China is aiming to join the small club of nations who have successfully returned scientific samples of asteroids for analysis on earth, teaching us more about how our and potentially other solar systems formed. Tianwen-2 launched successfully this week, bound for an asteroid known as Kamo‘oalewa, which sits in a very strange orbit of both the earth and the sun, making it a “quasi-satellite”. Last year, scientists including Patrick Michel of the Côte d'Azur Observatory in France, published an intriguing suggestion that Kamo‘oalewa might in fact not be a conventional asteroid, but instead be a small piece of our moon that was ejected when the Giordano Bruno crater formed. In a little over a year from now, we might find out if that is right.Do you have to hold text at arm's length to read properly?

It has been thought that ornate threads of strings and baubles known as khipu are how records were made for business and administration, probably by a decimal code of knots in strings. But the exact purpose, nature and any meaning encoded therein, has eluded scholars for decades. Sabine Hyland, an anthropologist at the University of St Andrews, Scotland, has been studying them for years, and recently was granted access to the records of a village, only the fourth known, to have continued a form of the khipu tradition after the Spanish conquest to this day. She believes that they could even provide us in the modern world with valuable climate data.

CLAUSE 4.0: Let me search for more information about China's broader solar system exploration strategy and Rick Fisher's analysis. China's Phased Asteroid Mission Strategy Bottom Line Up Front: China has developed an ambitious multi-phase approach to asteroid exploration and planetary defense, positioning itself as a major space power with systematic missions targeting asteroids, Mars, Jupiter, and potentially the outer solar system through 2050. Current Asteroid Missions (2025-2030) Tianwen-2 (2025): China will launch the Tianwen-2 mission to sample a near-Earth asteroid next year. The mission will first focus on sampling near-Earth asteroid Kamoʻoalewa (2016 HO3). After delivering samples to Earth, the spacecraft will use our planet for a gravitational slingshot maneuver and set it on a course for main-belt comet 311P/PANSTARRS. SpaceNewsSpace Planetary Defense Test (2025-2030): China is planning its first mission to impact an asteroid in the name of planetary defense. The mission will serve a dual purpose: One craft will impact the asteroid while its partner observes the space rock to learn more about the solar system and its formation. SpaceSpace China wants to test changing the orbit of a potentially hazardous asteroid with an impactor spacecraft and also accurately measure how much its orbit is altered. China will launch 2-in-1 asteroid deflection mission in 2025 | Space Expanding Solar System Dominance Strategy Deep Space Exploration Roadmap: China's plans for exploring the outer Solar System are taking shape, with Jupiter's moon Callisto and one of the ice giants the main targets.

China's plans for outer Solar System exploration Ice Giant Missions (2035-2050): Zhu provides a potential launch date of 2035 for a Uranus mission, arriving in orbit in 2050. If a Neptune mission is chosen instead, it would launch in 2040 and arrive in 2058. China's plans for outer Solar System exploration Infrastructure and Capabilities Development Planetary Defense Force: China is recruiting for a planetary defense force to combat the threat of asteroids colliding with Earth. The successful candidates will be required to research tasks related to near-Earth asteroid monitoring and early warning systems. Wanted: 3 asteroid watchers for China's 'planetary defense force' Advanced Detection Systems: The "compound eye," a 25-antennae network of radars, is under construction to bounce signals off deep space objects to determine their potential threat to Earth. The project is set to be completed in 2025. China targets its first planetary defense test mission Strategic Implications Rick Fisher, a senior fellow at the International Assessment and Strategy Center, has been analyzing China's space ambitions extensively. Rick Fisher talks about China's growing space ambitions—from the Moon, to Mars, to asteroids. Throughout the program, Rick talked about Chinese space policy, goals, objectives, hardware, all of it, as tools of the Chinese Communist Party (CCP) and as an implement of the PLA (People's Liberation Army). NTDThespaceshow China's systematic approach includes not just exploration but potential dual-use capabilities, advanced manufacturing in space (including plans for a lunar base by the 2030s Space-Based Solar Power and 21st-Century Geopolitical Competition | RealClearDefense and space-based solar power), and the development of comprehensive planetary defense systems that could have both protective and offensive applications. This represents a coordinated strategy to establish Chinese leadership across the solar system through the combination of scientific exploration, resource utilization, and strategic positioning—what some analysts view as China's bid to become the dominant space power of the 21st century.

A Chinese spacecraft that’s scheduled for launch as early as next month has a double destination: a “quasi-moon” of Earth and an asteroid that acts like a comet. The first destination for Tianwen-2 is an asteroid, Kamo’oalewa. It’s a chunk of rock no more than the length of two or three football fields. What makes it intriguing is that it weaves around the Sun in a pattern that makes it look like a satellite of Earth. The asteroid spends half of its time farther from the Sun than Earth is, the other half closer to the Sun. Seen from Earth, it appears to loop around our planet – like a moon. Some research suggests it was a chunk of the Moon that was blasted into space by a big impact. Tianwen-2 is scheduled to arrive at Kamo’oalewa next year. It’ll spend a year traveling along with the asteroid. It’ll drop off a small lander and rover, and collect a few ounces of rocks and dirt. The craft will swing by Earth to drop off the samples, then journey to 311P Panstarrs. The object is a third of a mile wide, and orbits the Sun at about twice Earth’s distance. Observations reveal that Panstarrs is rocky, like an asteroid. But soon after it was discovered it sprouted several long tails, so it was classified as a comet. It may be a loosely bound pile of rocks and dust. If so, it may sometimes lose some of the dust, and sunlight then pushes it away – giving this asteroid the tails of a comet.

Happy Halloween! In this special episode of The LIUniverse, Dr. Charles Liu and co-host Allen Liu welcome back archaeology expert Hannah Liu, MEd to bring a scientific eye to the holiday and some of its most familiar denizens: witches, werewolves, zombies, black cats and even the Great Galactic Ghoul! As always, though, we start off with the day's joyfully cool cosmic thing: Comet C/2023 A3 (Tsuchinshan-ATLAS). You'll learn all about this visitor from the Oort Cloud, including how we know where it came from. Hannah talks about how ancient people responded to the arrival of a comet, including how leaders have used them for their own political purposes, and Charles brings up the inclusion of Halley's Comet on the Bayeux tapestry. Then it's time for Chuck to introduce our theme for this special episode: how the superstitions of the past interact with the mysteries of science. You'll hear from Hannah about the history of Halloween and its beginning as the Druidic celebration of Sawen (or Samhain) marking the end of the harvest season. Jumping ahead in history, we look at the Salem Witch Trials of the 17th Century, and the “science” that was used to condemn innocent young women to death for behaviors the powers that be disapproved of. You'll also get serious answers to spooky questions like “Do full moons affect behavior?” (We're talking the behavior of moths, sea turtles and humans, rather than werewolves, although we do actually get into the possible origins of the wolfman myth as embodied in the Greek myth of Zeus and Lycaon with a minor digression into D&D and legendary DJ Wolfman Jack.) After witches and werewolves, what else could we talk about next than zombies? In this case, natural zombie spiders created by the sting of a parasitic Tarantula Hawk wasp, or zombie ants that have been infected by the fungus Ophiocordyceps unilateralis. And yes, somehow The Walking Dead and The Last of Us shamble into the discussion, although regarding the latter, Allen explains why cordyceps probably couldn't survive in a human host. Next up, we look at the connection between black cats and the holiday. Hannah brings up the traditions of cats as “Witch's Familiars” and shapeshifters, and Chuck reminds us of the moment when we saw a cat transform into Professor McGonagall in Harry Potter and the Sorcerer's Stone. You'll hear about how STS-13, which was slated to be the thirteenth mission of the Space Shuttle, was renamed STS-41-C, in an attempt to avoid any superstition or reminder of the ill-fated Apollo 13. There was an alternate mission patch that featured an illustration of the shuttle landing under a giant black cat, referencing the mission's original designation, STS-13; and that the day the mission returned was April 13, 1984, which was a Friday the 13th. Speaking of space, Hannah asks Chuck about the concept of “The Great Galactic Ghoul,” the fictitious space monster blamed for the failure of nearly every probe sent to Mars by the Soviet Union, Japan, and even NASA between 1988 and 1999. Out of 10 missions, only 2 US probes landed successfully on the Red Planet. Since then, while the Ghoul did claim a few more victims including two missions by the UK, it seems to have gone into hiding, since the US has had multiple successful missions, as has China with their Tianwen lander and Zhurong rover, India, Russia, the European Space Agency, and the UAE. Finally, to end our special HaLIUween episode, Chuck brings up Albert Einstein's term, “Spooky Action at a Distance,” which he coined derisively to describe the physics concept known as quantum entanglement that he dismissed but has since been proven to exist.

Astronomy Daily - The Podcast: 2nd September 2024Welcome to another episode of Astronomy Daily from Downunder. It's Steve here, bringing you the latest space and astronomy news on this second day of spring and September 2024. We've got a mixed bag of stories for you this week, from China's high-resolution map of Mars to SpaceX's Falcon 9 mishap, and much more. Let's dive right in!Highlights:- SpaceX Falcon 9 Mishap: The Federal Aviation Administration (FAA) has cleared SpaceX to restart its Falcon 9 launches following an investigation into a rare mishap during a first stage booster landing. The booster tipped over and exploded while attempting to land on a droneship off the Florida coast. Despite the mishap, the mission successfully delivered 21 Starlink Internet satellites into orbit. This incident ended a streak of over three years of successful booster landings.- NASA's Solar Sail Deployment: NASA's advanced composite solar sail system has successfully deployed in space. Launched on Rocket Lab's Electron vehicle, the solar sail reached full deployment on August 29. This innovative technology uses sunlight to guide its path through space and will be tested for maneuverability in the coming weeks. The data gathered will help design future solar sail missions for space weather monitoring, asteroid reconnaissance, and more.- Europa Clipper's Solar Arrays: NASA's Europa Clipper spacecraft has been fitted with gigantic solar arrays at the Kennedy Space Center. These arrays, each measuring 14.2 meters in length, are the largest ever developed by NASA for a planetary mission. They will help power the spacecraft as it investigates Jupiter's icy moon Europa, aiming to determine if its subsurface ocean could support life. The spacecraft is scheduled to launch on October 10 and will arrive at Jupiter in 2030.- China's High-Resolution Mars Map: China's Tianwen-1 mission has created the first high-resolution global color map of Mars. Developed by the Chinese Academy of Sciences, this map has a spatial resolution greater than 1 km and could support future crewed missions to Mars. The map was created using countless remote sensing images acquired by the Tianwen-1 orbiter.- Boeing's Starliner Return: NASA has announced that Boeing's Starliner capsule will depart the International Space Station no earlier than September 6. The capsule, which has faced multiple delays and technical issues, will return to Earth uncrewed. Astronauts Sonny Williams and Butch Wilmore, who were originally scheduled to return on Starliner, will now come back aboard a SpaceX Dragon capsule in February next year.- DART Mission Debris: Debris from NASA's DART mission, which tested a kinetic impact to nudge an asteroid, could potentially reach Earth and Mars. While it's unlikely we'll see a meteor shower on Earth, the debris could result in meteors on Mars. The DART mission successfully shortened the orbit of the asteroid Dimorphos around its parent asteroid Didymos.For more space news, be sure to visit our website at astronomydaily.io.

Entre las diversas misiones al espacio, la Agencia Espacial Europea (ESA) desarrolla el ambicioso proyecto ExoMars con el objetivo de buscar rastros de vida pasada en Marte. Sobresale el rover Rosalind Franklin concebido para esta misión, un vehículo capaz de perforar la superficie marciana a dos metros de profundidad. La Covid y la invasión rusa a Ucrania han hecho posponer su lanzamiento para el 2028. Se llama ExoMars por "Exobiology on Mars", una misión de astrobiología con el objetivo de buscar vida en Marte. La misión se compone de dos etapas diferenciadas y es un proyecto de la Agencia Espacial Europea (ESA). Recientemente, el director francés François Pomès National Geographic realizó un documental sobre esta misión y las peripecias que ha tenido a lo largo de su historia. Jorge Vago, el responsable científico de esta misión explicó a RFI los puntos fuertes de esta misión:Durante un tiempo contó con la colaboración de la agencia espacial rusa, Roscosmos, pero después de la invasión rusa a Ucrania, la ESA canceló dicha participación y su lanzamiento previsto en el 2022 tuvo que ser pospuesto. Hace unos meses se anunció un acuerdo de colaboración con la NASA y se ha replanificado el lanzamiento de la sonda para el 2028. Entre los puntos fuertes de esta misión está el rover concebido para esta misión, el Rosalind Franklin, llamado así en honor de la científica británica que contribuyó al descubrimiento de la estructura del ADN.Un vehículo de seis ruedas que cuenta con un taladro capaz de perforar y tomar muestras a dos metros de profundidad de la superficie marciana. Los rovers actuales que están en Marte, como el Curiosity o el Perseverance,  sólo pueden recoger muestras de la superficie. Como Marte no tiene movimientos tectónicos como la tierra, a dos metros de profundidad se pueden encontrar elementos muy antiguos. El objetivo es buscar rastros de vida pasada como fósiles de microorganismos o de otros materiales que pudieran expresar una forma arcaica de vida. Otro punto importante de esta misión es el lugar que la ESA ha escogido para aterrizar, el Oxia Planum, considerado un lugar con un alto potencial para encontrar dichos rastros de vida, pues millones de años antes era un océano marciano. El lanzamiento de esta misión se ha reprogramado para el 2028.

Episodio espacial dedicado a la basura espacial, un problema que tiende a agravarse cada día ACTUALIDAD Un tema de especial relevancia Nuevas megaconstelaciones de satélites De 4500 satélites activos en órbita, 1800 son de SpaceX Y pidieron permiso para lanzar 42.000 El operador de satélites más grande en la órbita baja terrestre Starlink ahora mismo implicados en 50% de las alertas de colisión (‘encuentros cercanos'), cuando estén desplegados los primeros 12k, subirá al 90% Las megaconstelaciones cambian un poco el juego. Muchísimos satélites en órbita. Son un riesgo en sí mismos Tienen 1700 avisos a la semana Tienen un sistema autónomo para CAMs Cada maniobra invalida los TLEs de Celestrak. Dificulta el control para otros operadores La NASA expresa su preocupación por el plan de despliegue de satélites de SpaceX por primera vez A la NASA le preocupa el potencial de un aumento significativo en la frecuencia de los eventos de conjunción y los posibles impactos en las misiones científicas y de vuelos espaciales tripulados de la NASA China denuncia ante la ONU que su estación espacial ha tenido que esquivar dos satélites de SpaceX China alega que los satélites Starlink se están volviendo demasiado abundantes e impredecibles en órbita, y quiere asegurarse de que Estados Unidos sepa que es responsable de cualquier daño que causen Pidió al secretario general que recordara a sus socios el Tratado del Espacio Ultraterrestre No está claro si el segundo de Starlink maniobró La delegación china afirma que un satélite Starlink se movía constantemente de manera impredecible ¿Un nuevo escenario de conflicto sinoestadounidense? China ha realizado una prueba que parece ser de retirada de residuos: El satélite Shijian 21, lanzado el 24 de octubre de 2021 desde Xichang en un Larga Marcha CZ-3B/G2 Experimental para validar tecnologías de retirada de basura espacial Se fue a GEO El 01/11 el Pentágono dijo que soltó un subsatélite. ¿Motor de apogeo? Realizaron varias maniobras de acercarse y alejarse Hace poco ExoAnalytic Solutions lo estuvo siguiendo con telescopios desde tierra. Se alejó del subsatélite, se acercó al Beidou-2 G2 (de posicionamiento [China tiene satélites de este sistema en GEO inclinadas]) Se fue acercando, y lo capturó. Luego, se lo llevó casi 3000 km por encima de GEO, a una órbita cementerio (y hacia el oeste de donde estaba). ¿Brazo robot? ¿En la tobera como el MEV-1? ¿Una red? No se sabe. China no dice nada. Este secretismo no les ayuda. Pero, de momento, está clara que su misión declarada es lo que era. Han retirado un satélite no funcional de una zona protegida. Es un logro notable. HISTORIA Un poco de Historia La humanidad ha generado basura espacial desde el principio El satélite más antiguo todavía en órbita es el Vanguard I, lanzado el 17 Marzo 1958, y se espera que dure 240 años (se usó y se usa para estudios de densidad atmosférica) Las últimas etapas de los cohetes se quedaban en órbita. Hay muchísimas todavía Eventos más famosos generadores de basura espacial: El proyecto West Ford (https://en.wikipedia.org/wiki/Project_West_Ford?wprov=sfti1) Esto es "genial". Una prueba de las locuras de la guerra fría En esa época las comunicaciones iban por cables submarinos o rebotando en la ionosfera. ¿Y si los soviéticos cortaban los cables? ¿Era la ionosfera suficientemente confiable? El plan era, atención, lanzar 480 millones de agujas de cobre, muy finas, de 1'78 cm (la mitad de la longitud de onda de la señal de 8GHz) Se lanzaron en tres ocasiones a alturas de más de 3000 km y a 96º y 87º de inclinación (casi polares) En la primera prueba, las antenas no se dispersaban, quedando todas juntas Se abandonó cuando aparecieron mejores soluciones, como los satélites de comunicaciones El embajador USA ante la ONU justificó que perturbaciones como la presión de radiación solar las harían reentrar en pocos años Pero no, algunos de los montones que no se desplegaron siguen arriba 11 de enero de 2007. Prueba antisatélite china (https://en.wikipedia.org/wiki/2007_Chinese_anti-satellite_missile_test?wprov=sfti1). 865 km de altura. Satélite FY-1C, de la serie Fengyun Destruido en un choque frontal con un impactador cinético. El último test anti satélite había sido en 1985 (un misil lanzado desde un F-15 estadounidense) Se detectaron casi 3500 trozos Se calcula que alrededor del 30% seguirán en órbita para el 2035 20 de febrero de 2008. Prueba antisatélite estadounidense (https://en.wikipedia.org/wiki/Operation_Burnt_Frost?wprov=sfti1) Un satélite de la NRO, el USA-193 Se justificó diciendo que llevaba hidracina muy tóxica y que se había perdido el control Se lanzó desde un barco Había un vuelo de la lanzadera espacial programado, así que esperaron a que aterrizara También lo querían muy bajo para minimizar el debris, pero no mucho, al no ser un cuerpo aerodinámico, lo que complicaría las cosas Ventana de ocho días Una altura de unos 250 km Se detectaron 174 piezas, que re-entraron en pocos meses. Dos duraron algo más. La última re-entró 20 meses después Siempre negaron que fuera respuesta a la prueba china. Febrero de 2009: El choque entre un satélite Iridium (operacional) y uno ruso Kosmos 2251 (https://en.wikipedia.org/wiki/2009_satellite_collision?wprov=sfti1). Primer choque entre dos satélites (aunque antes ya habían chocado satélites con debris). Altura de 789 km. Chocaron a 11,700 m/s de forma casi perpendicular Los cálculos realizados por CelesTrak esperaban que estos dos satélites fallaran en 584 metros. 10 días después se estimaron unos 1000 piezas de más de 10 cm (muchas más de tamaño menor). Un año después eran alrededor de 2000. 5 años después, 1500 seguían en órbita (otras habían reentrado) Restos de esta colisión pasaron cerca de la ISS (un trozo pasó a 120 m. La tripulación estaba en las Soyuz) Misión Shakti. 27 marzo de 2019. La India hace su prueba anti satélite (https://en.wikipedia.org/wiki/Mission_Shakti?wprov=sfti1). El objetivo era un satélite de prueba a 283 km Otro impactador cinético Supuestamente, empezaron activamente tras la prueba China Eligieron una órbita baja para minimizar los debris que se generaban Más o menos, en unos meses la mayoría habían reentrado. Los que llegaron más altos tardaron uno o dos años La prueba rusa del 2021. Hablamos de ella en el primer episodio y a ese episodio nos remitimos EL PROBLEMA YA NO ES QUE SE LANCE, SINO QUE NO SE RETIRE Algunas de las altitudes más congestionadas en la órbita terrestre baja son las que van de 750 a 850 kilómetros, un cementerio de satélites rusos, chinos y estadounidenses que han ido abandonándose a lo largo de las décadas. Algunos cuerpos de cohetes que orbitan la Tierra son enormes y pesan alrededor de 9 toneladas, como autobuses Otra altitud problemática es entre 1400 y 1500 kilómetros, donde no hay suficiente resistencia atmosférica para hacerlos frenar. A 500 o 600 kilómetros, el arrastre de la atmósfera derriba los escombros en máx. 10 a 20 años.  “A 1400 kilómetros, estará allí durante siglos” El Comando Espacial de EE.UU. actualmente rastrea alrededor de 35000 objetos de escombros, el 70% de los cuales están en órbita terrestre baja. LeoLabs rastrea objetos del tamaño de una pelota de béisbol y más grandes. McKnight dijo que hay entre 500000 y 900000 artículos más pequeños que actualmente no se rastrean y "cruzamos los dedos y esperamos que no nos golpeen". ALERTAS DE COLISIÓN El NORAD empezó a crear bases de datos recopilando lo que hay en el espacio desde el Sputnik ¿En qué consisten estas bases de datos? La información se almacena en lo que se conoce como Two line elements – el sistema clásico de parámetros orbitales Da información de la órbita y su evolución futura Son relativamente precisas para un cierto espacio de tiempo (días / semanas)… …dejan de valer si un satélite maniobra. Celestrak. Probablemente la principal base de datos a día de hoy Hay varias instituciones a día de hoy trabajando en generar alertas de colisiones CSpOC (Combined Space Operations Center en la Vandenberg Space Force Base). Desde 2005, antes se llamaba JSpOC (Joint Space Operations Center), se cambió el nombre en 2018). Hay empresas privadas, como LeoLabs. Muy críticos últimamente con todo el tema de la basura espacial. Después de analizar la probabilidad de colisiones en la órbita terrestre baja y las consecuencias en términos de desechos producidos, la startup de mapeo espacial LeoLabs advierte a los operadores de naves espaciales que se mantengan alejados de ciertas altitudes. "No compre condominios en el rango de 780 a 850 kilómetros", dijo Darren McKnight, miembro técnico senior de LeoLabs, el 6 de enero durante un webcast del Centro de Investigación y Política Espacial de la Universidad de Washington. Esa altitud alberga escombros de un evento ASAT chino, cuerpos de cohetes rusos abandonados y cargas útiles y escombros estadounidenses descartados. PD McKnight también advirtió sobre problemas a 1.400 kilómetros, donde los escombros se acumulan durante siglos. Aparte de decir de forma clara y casi brusca que opina que los USA van muy por detrás del resto en misión de contención de basura espacial. El radar S3TSR (Spanish Space Surveillance and Tracking Space Radar) está situado en la Base Aérea de Morón (Sevilla) y su operación y sostenimiento es responsabilidad del COVE (Centro de Operaciones de Vigilancia Espacial del Ejército del Aire), centro a través del cual España participa en el consorcio EU-SST. El primero de Europa en detectar los restos del satélite ruso Tselina-D tras su destrucción Maniobras para evitar la colisión: Primero se estudia el aviso (suele llegar del CSpOC). Se analiza (determina) mejor la órbita de los dos objetos. Se analiza la probabilidad. Se decide si se maniobra Cambio de órbita Cambio de periodo Consideraciones operacionales (impacto en el combustible y en la misión del satélite) MITIGACIÓN Qué se puede hacer antes, para evitar ser un debris Planificar el final de la vida: Motores, tethers, elementos de añadir resistencia Hay varias estrategias, en función de la órbita Reentrada Órbitas cementerio Para ayudar en Active Debris Removal (ADR): Marcadores, luces, pegatinas, enganches, sistemas de reducción del giro (los satélites muertos giran sin control, en general) Técnicas de retirada activa de basura espacial: Contacto Hay técnicas de tirar (son técnicas que no necesitan una sincronización muy compleja, es decir, el «detumbling» puede hacerse con el propio agarre), y técnicas de empujar (técnicas con una sincronización rígida). Tirar (laxos) Las redes con cable Los arpones con cable Un sistema de agarre con cable Empujar (sincronizados) Brazos robot (con o sin sistemas de amortiguamiento) Tentáculos. Sirven para casos en los que haya cierta incertidumbre en el cuerpo a capturar Sin contacto «Pastoreo» con impulsión iónica (los motores se ponen contra el debris — necesita motores al otro lado para compensar) Tractores electrostáticos Láser (mediante transferencia de impulso, o mediante ablación en el debris) Kits de desorbitación. Por ejemplo, con cohetes de combustible sólido, o con kits desplegables, como con cables, o superficies que incrementen la resistencia. Normalmente antes de capturarlos hay que cancelar su giro. Suelen estar girando sin control. Hay varias técnicas también, muchas relacionadas con los métodos anteriores. NORMATIVA Normativa. Vimos hace poco que Kamala Harris creó un marco de prioridades espaciales para Estados Unidos que incluye eliminación de desechos orbitales, pero no es más que una primera piedra Estados Unidos líder en lanzamientos espaciales, muy retrasada en la retirada de basura ¿Cómo se regula este tema? La normativa es muy escasa. No hay realmente nada a nivel internacional que obligue a tratar con el tema. Algunos países lanzadores pueden tener normativa, de forma que sólo lancen objetos que cumplan ciertas características (porque según los tratados en vigor, el estado lanzador es responsable de los daños que provoquen los objetos que lancen). Aparte de los tratados como el Tratado del Espacio Ultraterrestre, hay recomendaciones, que no obligaciones, como las Guías para la Mitigación de la Basura Espacial, del COPUOS, Comité para el Uso Pacífico del Espacio Ultraterrestre, u otra del mismo nombre del INTER-AGENCY SPACE DEBRIS COORDINATION COMMITTEE La Space systems — Space debris mitigation requirements - ISO 24113:2019, que es voluntaria) Locales. Las ECSS, por ejemplo Dos zonas de especial protección: LEO y GEO. Técnicas: reentradas u órbitas cementerio 25 años máximo en órbita Reentrada controlada si la probabilidad de bajas es mayor a 10e-4 EMPRESAS ¿Qué se está haciendo en este campo? Interés privado: DeorbitKit, RemoveDebris, AstroScale... Detección: LeoLabs, Privateer AstroScale tiene una misión ahora mismo haciendo pruebas, aunque han tenido que detenerlo recientemente por tener un problema Surrey también ha realizado pruebas en órbita Interés público: eDeorbit, Andorid, Clean Space (proyecto ESA, empresa privada suiza), prueba de retirar un adaptador de cohete. GEO: prolongación de la vida (dos misiones ya, las MEV de Northrop-Grumman) El problema es intentar controlar el número de objetos en órbita y, sobre todo, su riesgo. El objetivo hace unos años era retirar cosas grandes (ENVISAT y etapas de lanzadores. Básicamente, que no aumente el problema). Para mantener la situación bajo control se estima que el 90-99% debería desorbitar, lo cual excede las cifras actuales. La Space Force quiere colaborar con empresas privadas. Ha mostrado interés, pero de momento habla poco de financiación. El brazo tecnológico de la Fuerza Espacial conocido como SpaceWERX lanzó un programa llamado Orbital Prime que solicita propuestas de empresas privadas e instituciones académicas sobre tecnologías para eliminar desechos espaciales Los equipos pueden ganar premios en la Fase 1 de $250,000 y premios en la Fase 2 de $1.5 millones. Si se selecciona alguno para una demostración en el espacio, el gobierno financiará una parte del coste. INCLUSO EN LA LUNA Por terminar el tema, comentar que aunque el problema es básicamente terrestre, tenemos que tener cuidado en no «exportarlo» a otros cuerpos. Por ejemplo, recientemente (finales del año 2021), dos sondas lunares tuvieron una alerta. Chandrayaan-2 de la India realizó una maniobra el 18 de octubre para evitar un acercamiento con Lunar Reconnaissance Orbiter de la NASA Chandrayaan-2 realizó una maniobra dos días antes de la conjunción prevista para el 20 de octubre después de que los datos orbitales mostraran que las dos naves espaciales se acercarían a tres kilómetros entre sí. el anuncio pasó desapercibido porque se emitió el mismo día que ocurrió la prueba de misil antisatélite ruso Tanto la NASA como la agencia espacial india ISRO dijeron que se coordinaron entre sí en la maniobra, pero no revelaron cómo decidieron que Chandrayaan-2, en lugar de LRO, debería ser el que maniobre. Chandrayaan-2 entró en órbita lunar en agosto de 2019 y, en ese momento, los funcionarios de ISRO dijeron que la nave espacial tendría suficiente propulsor para operar durante siete años y medio. LRO, por el contrario, ha estado en órbita lunar desde 2009, la NASA dijo el año pasado que tenía suficiente combustible a bordo para al menos seis años más de operaciones. A finales de enero saltó la noticia de que un viejo cohete de SpaceX iba camino de estrellarse contra la Luna. Resulta que los astrónomos estaban equivocados. Sí, un cohete va a impactar de manera descontrolada en la superficie del satélite el 4 de marzo, pero no es la segunda etapa de un Falcon 9, sino el propulsor de un cohete Larga Marcha 3C que se usó en la misión china Chang'e 5-T1 en 2014. ¿PRÓXIMAMENTE MARTE? En marzo, la NASA confirmó que estaba intercambiando datos con la agencia espacial china sobre las órbitas de sus naves que orbitan Marte después de algunas frustraciones iniciales por la falta de datos sobre la órbita de Tianwen-1.

火星任务将暂停约50天|Mars mission to pause for about 50 daysChina's Tianwen 1 Mars mission will be inactivated for about 50 days from mid-September due to an expected disruption of its communications with Earth caused by solar electromagnetic radiation, the mission's chief designer said.中国天问一号火星任务的总设计师说,由于太阳电磁辐射导致其与地球的通信预期中断,该任务将从9月中旬起暂停约50天。During the period, which will end in early November, the Zhurong rover and the mission's orbiter will suspend their working mode, Zhang Rongqiao of the China National Space Administration told reporters on Monday. The rover had been operating on the Red Planet for 100 days as of Monday, while the orbiter has been circling Mars since February.中国国家航天局的张荣桥周一告诉记者,在于11月初结束前,祝融号探测器和人造卫星将暂停其工作模式。截至周一,探测器已经在火星运行了100天,而人造卫星自2月以来一直在围绕火星运行。"During that time, the Earth, Mars and the sun will almost be in a straight line and the distance between Earth and Mars will be farthest," Zhang said. "The sun's electromagnetic radiation will greatly affect the communication between the rover, the orbiter and ground control."“在这段时间里,地球、火星和太阳几乎在一条直线上,地球和火星之间的距离将是最远的,”张荣桥说。“太阳的电磁辐射将极大地影响火星探测器、人造卫星和地面控制之间的通信。”After they resume operation, the rover will continue traveling southward toward an ancient coastal area on Utopia Planitia, a large plain within the largest known impact basin in the solar system, for scientific exploration while the orbiter will enter a new Mars orbit to carry out a remote-sensing global survey of the Red Planet and will continue relaying signals between Zhurong and Earth, Zhang said.张荣桥说,在他们恢复运行后,探测器将继续向南行驶,前往乌托邦平原上的一个古老的沿海地区进行科学探索,这是太阳系中已知最大的撞击盆地内的一个大平原,而人造卫星将进入一个新的火星轨道,对火星进行全球遥感探测,并将继续在祝融号和地球之间传递信号。As of Monday, Zhurong had traveled 1,064 meters on the Martian surface and was in good condition with sufficient energy, Zhang said.张国华说,截至周一,祝融号在火星表面行驶了1064米,状态良好,能量充足。The core component of the Tianwen 1 mission, the country's first interplanetary adventure, the 240-kilogram Zhurong has outlived its three-month life expectancy with all of its predetermined tasks completed.天问一号任务的核心部分,即完成中国的第一次星际探险,重达240公斤的祝融号已经超过了它三个月的预期寿命,完成了所有预定的任务。The 1.85-meter-tall rover, which is now about 392 million kilometers from Earth, is the sixth rover on Mars, following five others launched by the United States.这个1.85米高的火星探测器现在距离地球约3.92亿公里,是继美国发射的五个火星探测器之后的第六个火星探测器。Tianwen 1, named after an ancient Chinese poem, was launched on July 23 last year from the Wenchang Space Launch Center in Hainan province and traveled more than 470 million km and carried out several trajectory maneuvers before entering Martian orbit on Feb 10. Zhurong touched down on the planet on May 15 and separated from its landing platform a week later.天问一号以中国的一首古诗命名,于去年7月23日从海南省文昌航天发射中心发射,在2月10日进入火星轨道之前,行驶了4.7亿多公里,进行了几次轨道机动。5月15日,祝融号在地球上着陆,一周后与着陆平台分离。The mission has generated more than 420 gigabytes of primary data, with Zhurong alone having obtained about 10 GB of primary data, according to sources at the space administration.据航天局的消息,该任务产生了超过420千兆字节的原始数据,仅祝融号就获得了约10千兆字节的原始数据。To mark the mission's achievement, the administration and the People's Bank of China issued a set of gold and silver commemorative coins on Monday.为了纪念这一任务的成就,航天局和中国人民银行于周一发行了一套金银纪念币。1. inactivate美 &英 [ɪn'æktɪveɪt]v.使灭活;使停止活动网络:使不活动;失活;使失去活性 2. electromagnetic美 [ɪ.lektroʊmæɡ'netɪk] 英 [ɪ.lektrəʊmæɡ'netɪk]adj.电磁的网络:电磁式;电磁制动;兼容裕量 3. orbiter美 ['ɔrbɪtər] 英 ['ɔː(r)bɪtə(r)]n.(绕天体作轨道运行的)宇宙飞船;轨道飞行器网络:人造卫星;盘旋物;轨道器 4. relay美 [rɪ'leɪ] 英 [riː'leɪ]n.接力赛;接班的人(或动物);轮换者;中继设备v.转发(信息、消息等);转播(电视或广播信号)网络:继电器;分程传递;传达 5. interplanetary美 [.ɪntər'plænə.teri] 英 [.ɪntə(r)'plænɪt(ə)ri]adj.行星间的网络:星际;生星际的;行星际的 6. trajectory美 [trə'dʒektəri] 英 [trə'dʒekt(ə)ri]n.轨迹网络:弹道;轨道;轨线 7. maneuver美 [məˈnʊvər] 英 [məˈnuːvə(r)]n.演习;谨慎或熟练的动作;花招v.巧妙地移动;用计得到网络:机动;调遣;操纵 8. commemorative美 [kə'memərətɪv] 英 [kə'mem(ə)rətɪv]adj.纪念的网络:纪念性的;纪念意义的成品;纪念物

Remember, we welcome comments, questions and suggested topics at thewonderpodcastQs@gmail.com   S2E09 TRANSCRIPT: ----more---- Yucca: Welcome back to the Wonder Science-based Paganism. I'm your host Yucca Mark: And I'm your host, Mark. Yucca: And this week we're actually talking about science. And how science plays into science-based paganism, what science really is, and a little bit around the current events with the relationship of science and paganism. Mark: Right. This subject is very timely as it turns out. We've been wanting to do this episode for a while. But as it turns out, there is a sort of controversial thread on Starhawk's Facebook page currently in which she expressed her happiness about getting the second installment of the COVID-19 vaccination and really had a number of people, I wouldn't say a majority, but quite a number of people, very hostile to vaccination, very hostile to the pharmaceutical industry, science products and really attacking her quite a bit personally for her going along with what we currently know in, in terms of medical science for addressing COVID-19. So we felt that it would be a good time to talk about science what it is, what it, isn't, how that dovetails with our scientific, science-based pagan practices and what that all means, how that all fits together. Yucca: Exactly. Yeah. So a huge amount to cover here. Mark: Yes. Yucca: So let's dive in. I think we should actually start with the topic of what is science in the first place, because this is an area where as important as it is in our lives, there's a tremendous amount of misconception around just the concept of science itself. Mark: Yes indeed. One of the, one of those misconceptions is something that atheists encounter quite a bit in their conversation with people who are, I guess what I would call credulous religionists people who have beliefs that are not evidence-based, but are more experiential based. So they believe things because they've had experiences or simply because they've been told that they're true by people who they believe. And that accusation is that atheists, and this would also be true of godless pagans, worship science or that our our trust in the products of science is as much faith based as the faith based Willie of someone who believes in God's, for example hear that pretty frequently in those circles. And it's not true. But in order to understand that it's not true you need to know what science is to begin with and what it's not. Science is not an assertion of a cosmology apropos of nothing. That's not what it is. It's not an assertion that these things are true and you must believe them. It's an evidence-based process. Yucca: So let's start by unpacking what somebody could mean when they say science. So typically in the English speaking world, if we say science, there's one of three things that we could be referring to. And first and foremost, science is a process. It's a process of inquiry of learning about the world and in school, they might've made you memorize the scientific method or the scientific process that you had to go through in each of the steps and observation, and hypothesis and all of that. And that's an idealized version of the process. In real life it's never so cut and dry and clean. It's very messy. But that's what we're doing. Now, science, when someone says science, they could also be referring to the body of knowledge, which has been gained through that. Process. So if you take a biology course or you pick up a book about physics, those are talking about the things that we have learned by doing science. Now, the third way that the word gets used is science can also refer to the institutions or the people who practice science. So when you read a headline that says science says XYZ is bad for you. Well, science as an a process can't say anything. It's a process. It's a tool that we're using a body of knowledge. Can't say anything, but institutions can take positions. They can draw conclusions, individual scientists can. The word can be used to mean any of those three things, but it's technical meaning really is that process of inquiry and there's, it's not just, Oh, I ask a question. I have to ask very specific kinds of questions for them to be scientific. They have to be independently, the evidence has to be independently verifiable and it has to be reproducible. It can't, to be scientific, it can't be just an experience that I personally had that no one else can verify. If I do an experiment, the results that I get have to be, somebody else in another lab on the other side of the world, or on, out in the field, has to be able to get those same results and to replicate that. Mark: In order for the hypothesis to be verified. Yucca: Yes. Yes. And you have to, when you set up your experiment, it has to be set up in such a way that you can disprove or support your hypothesis. And I'm kind of jumping around here but that leads me to one other really important thing that I want to, conceptual thing, that I want to bring up, which is in science, you cannot prove a hypothesis. There's mathematical proofs, it's a legal term. You can disprove. But you could only add evidence in support of an idea. Now, when you have enough evidence becomes overwhelming and we then switched to talking about that idea as a fact, we're always learning more, always coming back and refining our understanding, looking for the exceptions and rewriting the story. There's things that we took for granted that we put in textbooks for years, and then we go, Oh wait, the data doesn't support that. Mark: There's new data and it doesn't support. Yucca: And when that happens, that's exciting. That's where the good stuff is. Look for where the data conflicts with our previous understanding and, whole new fields spring out of that. Mark: I think it was Richard Fineman. I'm not entirely sure, but I think it was the physicist Richard Fineman, who said the most exciting words in science are not Eureka it's that's funny. Yucca: Exactly. And I also want to step back for a moment and say that, my background is I'm a scientist, so I'm an ecologist. And then I later went into the space sciences into planetary science. So I work both as an independent ecologist and am also a science teacher. So I get really fired up about all of this, but we often in our culture have this idea where. As though science is close to only certain people, you have to have a degree in this field or else you can't possibly be an authority in it, or you have to have your PhD and this and that, and have done your postdoc over here, right. Where there is use in there being in someone, having a degree in an area. But that is only the start. Most scientists, their knowledge. Yeah. They spent a few years in school and they learned some really important processes there. And some of the ethics that guide whatever their field is, but the real knowledge comes from the continual learning. Always going back, learning more, reading the literature in your field, experimenting. And that's not something that's just limited to someone who's got a degree. Everybody can do that. That's something that, and personally, I think that's a responsibility that we, as citizens of the modern world have. To be able to make informed decisions that are going to influence the direction that our society and our ecosystems and our world go in. Mark: I agree. I agree. And the term that we use for that is science literacy, which is much less about absorbing A pattern of facts and much more about understanding the thinking process that's involved in analyzing a given proposed statement so that we, as scientifically literate, people can look at a given proposal and say, well, Is that true or not, or is it likely to be true or not? And what is the available evidence that points towards it? And is there available evidence that contradicts it? What is the relative weight of that evidence that we're going to consider? Is it just somebody say so, or is it the consensus of a whole bunch of studies that have been done independently in order to draw the conclusion that they've drawn? And that's something called the hierarchy of evidence. Which is an important aspect of doing scientific analysis. I do not call myself a scientist because I'm not one, I don't do science. And I don't have a degree in it. I took a bunch of courses in college. But what I am is someone who's really fired up about science and has been since he was very young. And so I am an autodidact in various scientific fields. I'm interested in cosmological physics. I'm interested in planetary science. I'm very interested in physical anthropology and human evolution. These are fields that I am always pouring over the internet to learn things about because they just happened to scratch a particular itch that I have to want to know more. Curiosity is at the heart science. Yucca: Excuse me Mark: Go ahead. Yucca: I think you worked in conservation for many years. Didn't you? Have so a field that, that is very heavy leaf science-based with some other fields in tied in there as well. Mark: At its best. It's very science-based at its worst, it's sort of just opposed to change. I have, I've seen and, you know, regrettably been a part of some self-styled environmental efforts that were really just about, you know, people not wanting more houses in their neighborhood or more traffic or for their nice view to be spoiled. And it's not that spoiling a nice view. Isn't something important. I consider beauty to be a really important, element of human experience. In fact, it's one of the four sacred pillars in atheopagan . But that's not as science driven as say conservation of a wetland area for a set of endangered species which is more the kind of work that I prefer to do. Yucca: I pulled you away though. You are on a beautiful train of thought there about curiosity being the heart of inquiry and Mark: Well, yes. I mean, we have these four brains, right? We have these frontal neocortexes, and what they seek is answers because. That is our superpower as humans. We aren't fast. We aren't strong. We don't have, you know, giant teeth and claws. We are soft, squishy, slow extremely vulnerable organisms. But what we can do is we can think in our capacity to think, and our curiosity about the nature of the world enables us to do extraordinary things. Thanks. Yucca: Yeah. I mean, just this last month alone has shown some of the amazing things that we can do, especially when we work together on this stuff. I mean, last month we. Landed Perseverance on Mars, which has a little drone on it, right. Flying in another world's atmosphere. And that it's the one of many that have come before it. And all of the other missions that are there too. So the HOPE mission and Tianwen 1 mission. And we're just reaching out and exploring and answering questions that, that our ancestors could only dream to be able to answer questions like that for. Mark: Right. And of course the deepest question that Perseverance is designed to inquire into is are we alone? It's looking for life. It's looking for signs that life existed on Mars. And of course by a, and I don't mean are there other intelligent beings that were on Mars? That's not that's not what I'm talking about, but life, if life was on Mars, the way that it is on and perhaps still is deep in the soil, we don't know. But if life was on Mars, the way that it is on Earth, that means that life is not a fluke. It means that it's kind of common, right? Given the conditions life will arise. And that has profound impacts for every year aspect of human exploration, everything from art and philosophy and religion to to the scientific disciplines. So this curiosity, this burning curiosity in humanity, And our soaring imagination, our capacity to dream of these questions and their possible answers. It's deeply moving and inspiring. And so the scientific enterprise, it's not just. This sort of dry fact-finding mission. It is, it's kind of at the heart of the human project. Yucca: And I want to take a quick tangent about Perseverance mission for the search for life. One of the questions that I hear voiced quite often as, okay. So if there's life on Mars now, it's almost certainly not on the surface because Mars has lost most of its atmosphere. It's still has quite a bit of atmosphere compared to many other places, but the radiation environments very high, the temperatures can be quite extreme if it's there, it's almost certainly not on the surface. It's going to be several meters down. It's going to be at the. Polar ice caps, maybe in subsurface lakes. So why are we searching on the surface where we're fairly sure there is no current life? And the assumptions behind that is that if life is that now there's certainly more dead things than living. That's the case here on Earth. But also, the life which could have developed if it followed the same path as life on Earth during the short period of time that Mars was a wet, warm world. So there was about a billion year period. Mars actually was what we'd consider habitable before we were during its Noachian period. Well, the life would have most likely been microscopic at the time. But that would have influenced the chemistry of the lake bed, where we're searching currently. We're looking for what the chemical signs left behind. Types of minerals that could only form in the presence of organic matter or in the presence of these processes, which are not possible, as far as we can tell, abiotically. So we're searching where we can, and then we have the major ethical questions to then look at is okay. If we find those signatures, then we might go and look in the places where we might think that they'd be. But if they are there, we have to really think carefully about the possibility of contamination. Mark: Right, Yucca: Right. Do we want to introduce Earth life? To Mars and perhaps back to Mars, because the very popular hypothesis is that we come from Mars, that life developed first on Mars and then hitchhiked to Earth. Mark: In raining down in, in meteorites that had been struck off of Mars. Yucca: Yeah. Quite easy to go down the gravity hill. Right. So this is one of the questions that Perseverance and the other rovers and experiments might help us find out is are we Martians? Where are we from? Right. And that really changes our view of ourselves and our place in the cosmos. Mark: Yes. And as you can hear in the animation, in our voices, this is tremendously exciting stuff. The implications of this for just our understanding of ourselves and who we are and what we're doing here are really profound. So, you know, science, isn't just people titrating with glassware in a laboratory wearing white coats. It is, it's the search for it's the search for the text of reality. The factual nature of the objective world that we live in, the objective universe that we live in. Now that said there are questions that science cannot answer. And anyone who's involved with science, who's honest about it will acknowledge that this is the case ethical questions, for example. I may get sidetracked into game theory later on, but I'm not going to do that right now. Questions about morality are not, they do not lend themselves to the scientific process. Very well. We were not going to run an experiment where we take a population of people and say, okay, 50% of you murder is okay. 50% of the murder is not okay. Now we're going to run the experiment and see how well your society gets along. That's it's not going to happen. Yucca: Well, there, there are ways to set experiments up like that in a way that would be falsifiable. And that is what makes it scientific or not. But you couldn't answer a question like is what's the best color? What is the meaning of this song? You could answer questions like perhaps do humans have an instinctual morality, right? This is something that has been investigated. And we're leaning towards saying yes, there are certain things which are instinctual we've talked about before, like the idea of reciprocity and things like that are instinctually ingrained into us as animals where other animals have different things ingrained in them. So the what question you are asking is something that has to, you have to be able to test it. And if you can't test it, it's not scientific. That doesn't mean it's not valuable. That doesn't mean it doesn't have meaning in our lives. It's just not science and science doesn't answer that. Now there are certain questions, which right now are not scientific or unscientific, but one day may become scientific. Mark: Yes. Yucca: Multiverse questions for instance. Mark: Well, or they're even, here on Earth, which at one time were not scientifically testable, but now are I think of the question from the film and book contact by Carl Sagan, where the preacher character Palmer, Joss asks of Ellie, the the astronomer. Did you love your father? And she says, yes. And he says, prove it. And the truth is that when we talk about the brain experience of love, if you put a bunch of electrodes in somebody's head, you can actually track that there is a particular kind of state that equates to our felt sense of love, but that, so it is possible to prove these things, but that doesn't mean that's necessarily the most meaningful way of approaching that kind of a question. Science is a very powerful and robust set of tools, but it's not a universal set of tools. There are questions that we have to answer for ourselves around right and wrong and around qualitative betterness or worseness, that's a bad construction. That, that science is really not. You know, science is just not the way you're going to approach these things. So that leads me to want to talk about scientism. Does that seem like a good place to go? Now there's so much in this topic, honestly, you know, we were talking before we started recording and we realized, yes, exactly. We, we We realized early on, there's probably way more of this than will fit in a podcast, but we'll do our best. One of the accusations that I have seen in atheist circles a lot in the conversations between religionists, what I call credulous religionists, who are people who believe in things for which there is scant or no scientifically credible evidence. Like gods or souls or spirits or ghosts or magic, things like that. Those folks will often accuse people who use science as a system for defining the cosmology that they subscribed to as subscribing to scientism and scientism is portrayed as science as a religion that you just, you believe in it and it's faith based and you just believe in it because you believe in it. And it's just a choice, just like choosing to believe in Vishnu or Apollo. There are real problems with that proposal because the nature of science, first of all, is not to be declarative about what is true. What science says is according to the evidence we have thus far with the best analysis we've been able to apply, this is what is most likely to be true. And in some cases, that evidence is so overwhelming that we talk about those things as facts. I joked before the, the show started, gravity is real. We we have enough evidence available that nobody is not subject to gravity and it's not subject to what you believe in. Gravity is just real. Yucca: Sure. On some very large scales, Mark: yes, Yucca: Do we understand it properly. There are some real questions there, but right now, If I jump up, I'm falling back to Earth. Mark: You're going to fall back to Earth. Exactly. So, so this, what that means is that the body of knowledge that is accumulated together, which is some kind of sometimes termed as science, that body of knowledge is all a set of probabilistic guesses, based on evidence about what is most likely to be true. And the based on evidence part is the real difference, because, you know, I had an experience where where I heard a voice in my head and I believe that it was, you know, Vishnu talking to me. That is not scientifically credible evidence. It's not reproducible. It's not capturable in any way. And there are other explanations for that kind of phenomenon happening that are more likely to be true. So the accusation of scientism I feel has to do with a lack of understanding about what science really is. And in some cases and then willingness to understand what science really is, a desire that science be a faith based process. Like those others. But it isn't faith-based. That said it is a human enterprise and human enterprises have human frailties built into them. There's something called confirmation bias. We're all subject to it. Confirmation bias is seeing what you want to see. You know, the seeing what you want to confirm, what you already believe. And scientists are as subject to this as everybody else, which is why we have these double blind experiments in order to take the observer out of the equation of what the outcome of the experiment is. Because if we just leave it up to humans, to judge, they're going to go with their biases, they it's inevitable that they will. And there are some unethical scientists who cling to their beloved theory, even when the evidence flies in its face. That's a problem. There are some scientists who are unethical, who are paid by grants or other funding from particular sources that want the outcome of the science to be a particular way. And the scientist cooperates. That is a problem. Yucca: Although I'd like to say that is far less of an issue than is often accused. And when you look at within the peer reviewed world there in any journal worth its salt, there's the declarations in the actual article. So you can go and look, okay, are there any conflicts or anything that needs to be declared about the relationships between the authors and the subjects that they're presenting. Mark: Right, right. But all of this is to say that it's a human enterprise and humans have failings, and those can get sewn into the findings of certain studies. But the solution to that is not to throw science out. The solution is better science, exactly science that does not involve people that are so locked into their confirmation biases, that they can't let them go. Science that's done, you know, without people feeling pressure from their funders. So that's the beautiful thing about science is that it's, self-correcting the peer review process whereby other experts take a look at your out your results and do their best to tear it apart. Okay. Is a really powerful element of the scientific method. So once you've published your results, Oh boy, I found something. This is great. Then everybody in the world does their best to say, no, you didn't find anything here. Your methodology was flawed and your data was dirty and no. And maybe they're successful and they're right. And now you've learned something. Maybe they're unsuccessful and you were right. And now you've learned something. So in either case it's very important this constant accretion of experimental and evidential body of knowledge and then analysis of it. And then and then Prosecution of inquiry into those results to see whether they really stand up. It's all very important and it gives us knowledge with a high degree of certainty. In many cases. Yucca: And I do want to speak for a moment to the peer reviewed process. It is incredible on many fronts and gives us just as you've been talking about a high level of certainty, it is one of the areas where it really highlighted that science is a human endeavor and that it is fraught with human problems. And one of the challenges with the peer reviewed process is that it often can entrench pre-existing biases. There's a lot of examples. One of the classic examples is Dr. Eugene Parker and his idea of the solar wind. And that kept, he tried publishing multiple times the The experts in the V in the field that were reviewing his paper, kept throwing it out. Eventually it was published and he was then later vindicated. We found the solar wind, and now we have a probe named after him, which is incredibly rare to have a space mission named after a living individual. But there are many instances in which changing a paradigm is blocked by this process. So it's a process that helps us on many fronts, but has challenges on other fronts. And sometimes people will latch onto, well, here's the challenge with peer reviewed, or there's a challenge that there's a minority of scientists who are being paid or the challenge in what you can get funding for. But again, we don't want to throw the whole process out. We don't want to throw science out with that bath water because the science as a tool and even as an institution has allowed us to achieve and learn so much too that the world that we live in today would be unrecognizable to just a few generations back. Mark: Yes. Yes. Yes. And so this, you know, a lot of what we've been explaining here is this sort of love song to science, which is, you know, a wonderful thing, but I'd like to bring it back a little bit now, to science-based paganism and what that means to us and what that means in the broader context of the pagan umbrella of various kinds of faiths and paths. I initially stepped away from the pagan community after practicing with it for 27 years. No, that's not right. 22 years. Because of experiences that I had that just were so far out of consistency with anything that could be scientifically validated that I just became incredibly uncomfortable. And then that got exacerbated by two instances where people used supernatural explanations to excuse really unethical behavior, in my opinion, and that, I mean, at that moment, it's like, well, you could excuse anything because you can just say that, you know, some spirit told you to do it or Yucca: God wanted it. Mark: Yeah, exactly. And we've certainly seen through history, what, what can happen. The horrible things that can happen when somebody says God wants it. And so I stepped away and I mean, you've heard this story before. I, I. I started to miss it a lot. And that got me into an inquiry about, well, what is religion? How does that, what does that have to do with the brain? What in the human organism is religion serving, right? And what I came back to was a frame, a framing of a particular path within science-based paganism called atheopagan ism. And the reason that the science base is so important is that it gives us a solid evidentiary base. For understanding the nature of the universe that we live in which we can then celebrate Revere live in service to it, it provides the foundation on which a rich, emotionally satisfying ethically coherent religious practice can be built. And that is why that's why I'm on this podcast right now. It's why I'm doing the things that I'm doing to promote science-based paganism in the world. My, my belief personally, is that the world, as it is the world as described by science is so marvelous, so extraordinary and beautiful and amazing and strange and mysterious. And. All of those, you know, kind of super-light of adjectives that I don't need or want anything else to worship or celebrate or revere in order to have a very rich and abundant life. And that doesn't mean that those other things don't exist. It means that they don't meet an evidentiary standard that I find compelling. Well, I'll leave it there. How about you? Yucca. Yucca: Well, I mean, there's so many directions to go with this. I want to come to the idea of, so we've been talking about what science is and what scientists do and all of this, and, but bringing it back to being pagan and how that informs our understanding of the world of ourselves, of existence, where most pagans, and most of us in our daily lives are not doing formal science. There's a lot of pagans who are scientists, right. That's really common. I think the very first episode has shared that in my early 20 years being at LANL with a bunch of the LANL folks. So Los Alamos National Laboratory, that a ton of them were pagans. Right. That's really common. But in everyday life how we use science as a way of understanding and informing our decisions around the world, what is this being science based? And I think that for me, well, one it's using the scientific method in my daily life, but also informing my understanding on things that I value and the choices that I make looking at what we have learned from science about these things and lifestyle choices. In my way of understanding what ritual is or how can I level up my ritual? Okay. I want to level up my ritual. I'm going to go read as much as I can about what the field of neuroplasticity is talking about right now. What have they found out? Right. And even if one doesn't have a formal training in these fields, the summaries of these, of the experiments done. There's lots of, you know, pop science books and articles and podcasts. There's tons of podcasts out there by scientists who are translating their field into a more accessible format and just looking for as much information as I can. And keeping that really open mind. The, you know, the good mind of a scientist, even if you're not formally trained as a scientist, you can still have a scientist's mind. And that's where the science-based comes in for me with paganism. Mark: I really agree. And certainly in terms of my my environmental ethic. Choices about, you know, why I decided to drive an electric car, you know, these kinds of things certainly come down to science-based assessments that I've made based on what my values are around how much do I want to impact the atmosphere? How much do I, you know, want to consume energy, all those kinds of things. The other piece when talking about science-based paganism, I think both of us have articulated really well, what it means to us as individuals, but science-based paganism is also a movement. It's been on the move in recent years and there's more and more attention to it. There's more and more people participating in it which is exciting. And I need to say a little bit about why I think that's it important because I have high hopes for paganism. I think that reverence for the Earth, which brings us forth and sustains us throughout our lives and for the Sun, of course, which is the energy source, which drives all of that process. It's such a truthful form of spirituality. It's rooted in reality. And that's why it is so much more moving to me than some others, which, as far as I can tell are not so much rooted in reality. They're rooted in stories and I love stories. I love stories and I love myths and I love metaphors and, you know, symbols and imagery and all that stuff. And I use it all in my rituals. But when it comes to what I'm going to direct, my spiritual love towards. I want it to be real. I want to know that it's real. And the best tool that we have for knowing things is science. So my hope is that over time, the pagan community will become more science-based and people who don't want to be science-based, they don't have to be, you know, I'm not trying to convert anybody, but my hope is that more and more of us will become more scientifically literate and will become a movement that stands up and starts to speak with credibility. In our society about what's really important here, you know, how should we be living in relation to the natural world? How should we be living in relation to one another? Because right now that language is all about money and money besides being imaginary. Which doesn't mean it isn't real. It just means that it's something that we've collectively decided to behave as if it's real. That's an insufficient capture of value. And I want to live my life in relation to what is most of value. That at root that's really where I am with it. Did we actually run out of stuff to say on this topic? I can't believe it. Yucca: Well, choose a topic and I can run off on a tangent with it. But I think that for the story of today, far as the story of this podcast I think that this is a wonderful place to wrap up and say as always, we so appreciate all of you being here with us and taking the time out of your day to listen. And for the feedback that we get from you just for being part of this movement, this community. Mark: Yes. Yes. Very much so. The I'm always just so tickled when someone joins the Atheopagan Facebook group, for example, and says, Oh, I heard you on a podcast. Or if they leave a comment on the blog. Yes. So I was listening to this thing called the wonder and I heard about the blog. It's just, it's really heartwarming. And to know that these ideas and this direction for spirituality is, has real appeal for people. Well Yucca. Thank you so much. What a wonderful conversation I've really enjoyed today. Yeah. Yucca: Likewise. Thank you.
