Recent volcanism on Mars reveals a planet more active than previously thought A vast, flat, "featureless" plain on Mars surprised researchers by revealing a much more tumultuous geologic past than expected, according to a study led by researchers at the University of Arizona. Enormous amounts of lava have erupted from numerous fissures as recently as one million years ago, blanketing an area almost as large as Alaska and interacting with water in and under the surface, resulting in large flood events that carved out deep channels. Why Mars is not geologically dead Lacking plate tectonics - shifting chunks of crust that constantly reshape Earth's surface - Mars has long been thought to be a geologically "dead" planet where not much is happening. Recent discoveries have researchers questioning this notion, however. Just last year, a team of planetary scientists, also at UArizona, presented evidence for a giant mantle plume underneath the region Elysium Planitia, driving intense volcanic and seismic activity in a relatively recent past. In the most recent study, a team led by Joana Voigt and Christopher Hamilton at UArizona's Lunar and Planetary Laboratory combined spacecraft images and measurements from ground-penetrating radar to reconstruct in three-dimensional detail every individual lava flow in Elysium Planitia. The extensive survey revealed and documented more than 40 volcanic events, with one of the largest flows infilling a valley named Athabasca Valles with almost 1,000 cubic miles of basalt. "Elysium Planitia is the youngest volcanic terrain on the planet, and studying it helps us to better understand Mars' past as well as recent hydrological and volcanic history," the authors write in their paper. Although no volcanic activity has so far been observed on Mars, "Elysium Planitia was volcanically much more active than previously thought and might even still be volcanically alive today," said Voigt, the first author of the study, published in the Journal of Geophysical Research: Planets. A plethora of Mars quakes recorded by NASA's InSight lander between 2018 until 2022 has provided proof that beneath its surface, the red planet is anything but dead. "Our study provides the most comprehensive account of geologically recent volcanism on a planet other than Earth," said Hamilton, associate professor at LPL. "It is the best estimate of Mars' young volcanic activity for about the past 120 million years, which corresponds to when the dinosaurs roaming the Earth at their peak to present." The findings have implications for research surrounding whether Mars could have harbored life at some point in its history, according to the authors. Elysium Planitia experienced several large floods of water, and there is evidence that the outpouring lava interacted with water or ice, shaping the landscape in dramatic ways. Across Elysium Planitia, Voigt and her co-authors found ample evidence of steam explosions, interactions that are of great interest to astrobiologists because they may have created hydrothermal environments conducive to microbial life. The team used images from the Context camera onboard NASA's Reconnaissance Orbiter, or MRO, combined with even higher-resolution images from MRO's UArizona-led HiRISE camera in selected areas. To obtain topographical information, they took advantage of data records from the Mars Orbiter Laser Altimeter on another NASA spacecraft, Mars Global Surveyor. These survey data were then combined with subsurface radar measurements taken with NASA's Shallow Radar, or SHARAD, probe. "With SHARAD, we were able to look as deep as 140 meters (460 feet) below the surface," said Voigt, who completed the study as part of earning her doctoral degree at UArizona. She is now a postdoctoral researcher at Caltech's Jet Propulsion Laboratory, or JPL, in Pasadena, California. "Combining the datasets allowed us to reconstruct a three-dimensional view of the study area, including what the topography was like befo...
Marte é um planeta fascinante que tem sido o assunto de muitas pesquisas científicas por séculos. No entanto, ainda há muito que aprender sobre este lugar misterioso. Uma nova pesquisa sugere que, debaixo de uma região chamada Elysium Planitia, pode haver uma enorme pluma de convecção de 4.000 quilômetros de largura no manto marciano que transporta magma derretido até a superfície, o que pode ser a fonte da atividade vulcânica observada no planeta. Esta descoberta está levando os cientistas a acreditarem que se existiu vida, essa vida ancestral ainda está viva no subterrâneo.

Experimental compound shown to block effects of multiple harmful drugs | New Atlas (01:20) Naloxone is a medication used to reverse or reduce the effects of opioids, which is commonly used to counter decreased breathing in an opioid overdose. A new chemical shows promise for serving a similar role, but it also works on non-opioid drugs.Known as Pillar[6]MaxQ (P6AS) It was developed at the University of Maryland, and it was recently tested on lab animals for the first time. Once P6AS is injected into the bloodstream, it binds with the molecules of certain other compounds and sequesters them into its central cavity, where they're surrounded by an outer layer of water.Altering the bound compound's chemical, physical and biological qualities.Resulting in blocking their effects on the body. In the mice model tests, P6AS proved to be highly effective at mitigating the effects of fentanyl – which is an opioid – but also on methamphetamine, which is not.Additionally it showed to do well at neutralizing non-opioid drugs such as PCP, ecstasy and mephedrone. Captured drug molecules were subsequently passed in the urine It should be noted that in the case of methamphetamine dosing, P6AS had to be injected within five minutes in order to be effective. Would likely be too small of a window in the real world The scientists are now working on lengthening those times, for opioids and non-opioids alike. It'll be several years before P6AS is available for general use. 'Mars' interior is not behaving,' active mantle plume reveals | Live Science (06:30) NASA's InSight mission has detected quakes and even evidence of recent volcanism around one Martian region, known as Elysium Planitia. Now, they think they know why this activity is occuring. This study appears to be the first active mantle plume discovered on the Martian surface.Findings suggest that Mars may be cooling significantly more slowly than scientists had anticipated. Mars lacks separate tectonic plates; instead, its crust is a single continuous sheet sitting atop the mantle.Therefore scientists think the volcanic activity on Mars must be the result of mantle plumes. Mantle plumes are columns of hot, rising material in the Earth's mantle that can cause volcanic activity and create hotspots on the Earth's surface.Mantle lies between the crust and the core. In short this finding suggests that Mars is still cooling, just more gradually than scientists had assumed. The study concludes by stating:“A plume beneath Elysium Planitia indicates that the surface volcanic flows and seismic activity are not isolated events, but part of a long-lived, actively sustained, regional system, with implications for the longevity and astrobiological potential of subsurface habitable environments.” In other words, the presence of this regional system suggests that there may be areas below the surface of Mars that have conditions that could be suitable for life to exist. Haptic hydrogel "skin" simulates touch in VR and AR | New Atlas (10:36) Engineers at the City University of Hong Kong have developed a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.Called WeTac Most haptic feedback devices are big and bulky, and require complex setups and tangles of wires.WeTac system looks like one of the neatest iterations The system is made of a rubbery hydrogel that sticks to the palm and front of the fingers, connected to a small battery and Bluetooth communication system located in a 5-cm2 (0.8-sq-in) patch on the forearm. That battery can be recharged wirelessly. The hydrogel is dotted with 32 electrodes spread across the palm, thumb and fingers, and electrical currents are sent through these to produce tactile sensations.Can simulate a range of experiences: catching a tennis ball, feeling a virtual mouse walk across your hand, or a negative feedback such as touching a digital cactus. Not interested in the video game applications, but this device could even help users remotely control robots, transmitting the tactile sensation of what the robot is grasping to its human operator. Pill technology releases molecules by exposure to UV light | Brighter Side News (15:37) Researchers from Tel Aviv University developed a new technology that will allow controlled encapsulation and release of molecules by exposure to UV light. The researchers estimate that the technology will lead to further development of delivery systems for controlled release of biomolecules and drugs in the body by external stimuli, using light. Development was inspired by viral compartments formed by the measles virus.The virus forms compartments that host all the reactions involved in the formation of new viral particles called viral factories. Dynamic and liquid-like structures that are formed inside the host cell The researchers designed a peptide (short minimalistic protein) which forms compartments that resemble viral factories for encapsulation of biomolecules. Additionally, they incorporated a unique element to the peptide sequence that enables a control of the encapsulation and release of molecules by irradiating the compartments using UV light. Dr. Ayala Lampel, who supervised this study stated on the potential of this technology:“This technology opens opportunities for biomedical and biotechnological applications including encapsulation, delivery and release of drugs, protein, antibodies or other therapeutic molecules.” A new water-based switch is thousands of times faster than current semiconductors | Interesting Engineering (21:04) Researchers have developed a water-based switch that becomes conductive thousands of times faster than current state-of-art semiconductor-based switches. Used in computers, smartphones, and wireless communications. Transistors are a crucial component in electronic devices because they can control the flow of electricity through a circuit, effectively acting as a switch. The building block of modern electronics, allowing for the amplification and switching of electronic signals. The faster a transistor can switch, the faster a computer system can perform tasks. To create this water-based switch:The researchers used a highly concentrated sodium iodide dissolved water and sprayed this salty water from a custom-made nozzle as a thin sheet only a few microns (micrometers) thick. Next, the water jet was excited with a short but powerful laser pulse at 400 nanometers (nm).This bumps electrons out of the dissolved salts, increasing the conductivity of water. Since the laser pulse is so fast, the water becomes conductive and behaves almost like a metal. All of this happens in less than one trillionth of a second, which translates to potential computer speeds in the terahertz (THz) range.Making this water-based switch faster than the fastest semiconductor switching speed currently known. Terahertz devices could someday enable much faster computing, and water-based technology could offer a more environmentally friendly alternative to rare-earth metals.

Show Notes: InSight hears meteoroid impacts on Mars | EarthSky (01:15) Since 2018, NASA's InSight lander has been busy studying the interior of Mars detecting over 1,300 marsquakes NASA announced on September 19, 2022, that, for the first time, InSight has heard the impacts of four meteoroids as they crashed into the Martian surface. Detected the vibrations from the impacts in 2020 and 2021. The impacts produced small marsquakes, up to a magnitude of 2.0. This is the first time that InSight – or any Mars lander or rover – has ever detected the seismic waves from a meteoroid impact. The four impacts occurred between 53 and 180 miles from InSight's location in Elysium Planitia. Elysium Planitia, a flat-smooth plain just north of the equator making it a great location to study the Martian interior. NASA's Mars Reconnaissance Orbiter took images of the impact sites from orbit. Appeared as dark spots in the orbiter's black-and-white Context Camera. The seismic waves generated by the impacts can give scientists clues about both the impacting rocks and the Martian subsurface. Additionally, scientists can use impact craters to determine the age of the surface. More craters = Older the surface is By using both InSight's data and orbital images of the impact craters, researchers can determine the meteoroid's trajectory and size of its shock wave (seismic wave). 7,000-year-old structure near Prague is older than Stonehenge, Egyptian pyramids | Live Science (05:27) Archaeologists digging near Prague have discovered the remains of a Stone Age structure that's older than Stonehenge and even the Egyptian pyramids: an enigmatic complex known as a roundel. 7,000 years ago during the late Neolithic, or New Stone Age Viewed from above, roundels consist of one or more wide, circular ditches with several gaps that functioned as entrances. "Roundels are the oldest evidence of architecture in the whole of Europe," according to Jaroslav Řídký, a spokesperson for the Institute of Archaeology of the Czech Academy of Sciences (IAP). Radio Prague International reported, the excavated roundel is large — about 180 feet (55 meters) in diameter, or about as long as the Leaning Tower of Pisa is tall Clear that this was part of the Stroked Pottery culture, which flourished between 4900 B.C. and 4400 B.C. Located in the Bohemian region of the Czech Republic Many farming villages found near the intersection of contemporary Poland, eastern Germany and the northern Czech Republic Carbon-dating organic remains from this roundel excavation could help the team pinpoint the date of the structure's construction and possibly link it with a Neolithic settlement discovered nearby. Watch this team of drones 3D-print a tower | MIT Technology Review (09:03) A mini-swarm's worth of drones have been trained to work together to 3D-print some simple towers. Could, one day, help with challenging projects such as post-disaster construction or even repairs on buildings that are too high to access safely. The process has multiple drones work together to build from a single blueprint, with one essentially checking the others' work as it goes. Inspired by the way bees or wasps construct large nests To demonstrate the drones' capabilities, the researchers got them to use foam and a special lightweight form of cement to build structures with heights ranging from 0.18 meters to 2.05 meters. The technique is limited for now because drones struggle to carry heavy loads, need regular charging, and still require human supervision. The researchers are hoping to alleviate some of these issues by automating the charging of drones during projects World's largest geothermal lagoon planned for Canada | New Atlas (14:12) A project, called geoLagon, is underway in Canada for a magnificent new open air lagoon in Canada that will be kept at balmy temperatures year round through a “huge Thermos” heating system underneath. Designed to be the largest of its type in the world Modeled on the famous geothermal lagoons of Iceland, the geoLagon is designed as an open-air attraction for visitors to relax and soak up the surroundings. To be built in Charlevoix, Quebec, span some 12,000 square meters (130,000 sq ft) warmed to a pleasant 39 °C (102 °F) all year It will be heated through an energy ecosystem consisting of geothermal, biomass, photovoltaics and solar heating systems, along with a thermal reservoir beneath the lagoon's base to store heat. Clusters of chalets will surround the lagoon once the project is completed, capturing solar energy with photovoltaic cladding to help run the heat pumps for the water. CEO Louis Massicotte says that further optimizations and technologies like sewer heat recovery could see the geoLagon village even become an energy provider, but is positive that the project will at the very least be able to sustain itself without drawing power from the grid. The project is planned in three stages, beginning with the construction of 150 solar-powered cottages, followed by the lagoon as the second stage and then the remaining 150 chalets thereafter. Expected to get underway in March and should take around 18 months. Israeli researchers managed to produce 3D printer ink to make wooden objects | Interesting Engineering (18:29) This Wood Ink is made from a mixture of wood flour and plant extracts. Doron Kam, a Ph.D. student working on the project, and colleagues developed this technology at the Hebrew University of Jerusalem. The technology converts organic "wood derivatives" into a paste that is then used as ink by a 3D printer. The scientists have so far used 3D printing to construct saddle, dome, and helix-shaped models out of their wood-infused ink. They think it might be used to make more sophisticated self-assembling products like furniture. What is the plan for this material, according to Doron Kam: “We are trying to make a material that won't last forever, that's what plastic is for. We are not looking for that … Three or four years of use, and then you can grind it down and print it again. This is sustainability in our product, this is our principle.”
Even as several Mars missions continue to drive across the planet or probe it from orbit, another mission is signing off. Without a good sweeping by a dust devil, it'll become a victim of dust — a fine orange powder that coats everything. InSight arrived in November 2018. It's not a rover, so it's stayed in the same spot, in a plain called Elysium Planitia. The craft has two major instruments. One is a seismometer. It's recorded more than 1300 marsquakes. It heard the strongest on May 4th, at fifth magnitude. The quakes have helped scientists map the layers inside Mars. The crust is thinner than expected, while the core is bigger. The core is still molten, which means its iron must be mixed with other elements that melt at lower temperatures. The other instrument was supposed to drill below the surface to measure the planet's internal heat. It couldn't penetrate the dirt, though, so it was abandoned. InSight is powered by solar panels. Over the years, dust has collected on top of them. Engineers cleared some of it off, but not all. By May, the coating had reduced the craft's power levels by 90 percent. So its instruments — including a weather station — are shutting down. Without a helping wind to clean it off, InSight should go silent later this year. Look for Mars rising near the Moon after midnight. They're high in the sky at first light. Mars looks like a bright orange star — colored by the dust that's doomed Mars Insight.

President Biden has been dragging his feet on relaxing Trump’s inhumane restrictions on refugees, leading to a lot of head-scratching and anger from Democrats and immigrant and refugee rights groups. According to new reporting by CNN, the reason for the delay is that Biden is fretting over the “political optics” of allowing more refugees into the country. The delay has left thousands of people seeking refuge in a state of limbo after an already lengthy waiting process. The Guardian reports that police officers and public officials from around the country have been donating to Kyle Rittenhouse’s legal defense fund. An executive internal affairs officer from Norfolk Virginia gave a donation that said “keep your head up, you’ve done nothing wrong.” The Florida Senate passed an “anti-riot bill” that Republican Gov. Ron DeSantis has been drooling over. According to the Orlando Sentinel, the bill will “grant civil immunity to people who drive through protestors blocking a road; prevent people arrested for rioting or offenses committed during a riot from bailing out of jail until their first court appearance; and impose a six-month mandatory sentence for battery on a police officer during a riot.” In addition, “A new crime of “mob intimidation,” defined as three or more people “acting with a common intent” forcing or threatening to force another person from taking a viewpoint against their will, is created by the bill. It is punishable as a first-degree misdemeanor, and bail is denied until first court appearance for anyone charged with the crime.” More alarming news on the climate front. In a new study by the Key Biodiversity Areas Secretariat in Cambridge, UK, scientists found that “just 3% of the world’s land remains ecologically intact with healthy populations of all its original animals and undisturbed habitat,” according to The Guardian.

Writing in the The Nation, Jane McAlevey argues that the effort does not mean that unionizing Amazon plants are doomed; rather, there were warning signs all over that the campaign had some serious problems - some due to Amazon’s union-busting efforts, but also due to some “fatal flaws” in the organizing campaign itself.

The Philadelphia Police Department launched a short-lived initiative to combat gun violence in the city this week. Commissioner Outlaw announced that the police department was going to team up with the Department of Parks and Recreation and teach children about gun safety. The problem? The Commissioner stated that they were going to use the NRA’s Eddie Eagle program without stating it was an NRA backed program. The initiative lasted less than a day after gun safety advocates and residents pounced on this idea. Philadelphia Councilmember Kendra Brooks, introduced two bills this week that would end practice of landlords denying turning away prospective tenants based upon eviction records. Brooks explained her rationale to WHYY: “Structural barriers and biases in the renting process disproportionately impact low-income renters, especially Black women. And as we know, these same renters have been hit the hardest by the pandemic. We must work toward a pandemic recovery that leaves no one behind and protecting renters’ rights to access affordable rental properties is a key part of that.” PASSHE Chancellor Dan Greenstein, made his case for his plan to fundamentally redesign the 14 state-owned university system to the Board of Governors on Thursday. Board of Governors Chair, Cynthia Shapira, called Greenstein’s remarks “inspirational” as she threw her support behind his plans to merge 6 of the universities into 2; fire hundreds of faculty and staff; and force students into more online classes. A piece of good news from the meeting that is getting much more coverage is the Board agree to freeze tuition for a third straight year.

Since landing in Elysium Planitia in 2018, InSight has been busy - detecting more than 500 Mars quakes and beginning to measure Mars’s core. Scientists say the lack of the powerful gusts of wind that are common in other parts of the planet have led to the build up. Still no flight for Ingenuity. An expected test flight for the little Mars helicopter was called off earlier this week due to a software issue related to its flight control. A fix has been identified and the NASA team say that Ingenuity may be ready to give it another go as early as next week. Acting NASA Administrator Steve Jurczyk announced that not only will the Artemis mission put the first woman on the moon, it will also send the first person of color as well.

For most of the United States, the winds tend to be pretty calm at this time of year, even in the Great Plains. On the “plains of paradise” of Mars, though, summer is the windiest time of year. As measured by the InSight lander, the winds are about five miles per hour faster in summer than in winter. InSight is designed to study the interior of Mars. It’s using a seismometer to measure “marsquakes.” And it’s been trying to deploy a probe to measure temperatures below the surface. But it also carries a small weather station. The station measures temperature and pressure, plus the speed and direction of the wind. InSight sits on a volcanic plain, known as Elysium Planitia. There are no mountains or canyons around, so there’s nothing to obstruct the winds. InSight’s readings show that the wind is strongest in the morning, not long after sunrise. And it’s weakest not long after sunset. And it’s also stronger in summer — an average of about 13 miles per hour, versus about eight miles per hour in winter. The most powerful wind gust was recorded during a big dust storm — about 70 miles per hour. The Martian atmosphere is so thin, though, that if you were standing on Mars you’d barely feel it — a thin breeze on the Red Planet. And Mars teams up with the Moon tonight. The planet is quite close to the Moon as they climb into good view, around midnight, and just as close at first light. Mars looks like a bright orange star. Script by Damond Benningfield Support McDonald Observatory
On May 5, 2018 the NASA Mars Lander InSight was launched to explore the inner geography of Mars. Although meant to study the planet's core InSight captured the sounds of wind rushing across the Elysium Planitia using geographic sensors. While winds on Mars are a common occurrence this is the first time the winds of mars have been recorded. NASA utilized the lander's seismometer to capture vibrations from a solar array nearby. InSight's air pressure sensor was also used to record Mars' winds and it captured the higher frequencies of the sound. Because these sensors pick up such low frequencies the recordings had to be sped up by over 100x in order to be audible to the human ear. Since Mars' atmosphere is composed mostly of CO2 the atmosphere is thinner meaning the wind's soundwaves have less energy than on earth, despite wind speeds of 10-30mph. This sound uses the two sets of recordings to create a creative composite recording of what wind might sound like on mars. Low frequency waves rumble while higher frequencies rise and fall, dampened by the thin atmosphere. Because of the frequency response of this sound it may be useful for masking tinnitus or distracting sounds. To fully experience this sound we recommend good headphones or speakers to reproduce the low rumbling of the Martian winds. Learn more about the White Noise App Download the White Noise app for free!

NASA’s InSight Mars lander keeps daily records of weather conditions at the Elysium Planitia landing site on the red planet.

Seasons are twice as long on Mars as on Earth because the Martian year is 687 days; almost double an Earth year. Mars doesn’t have months like we have months though. Our concept is based on a lunar orbit. Mars’ moons orbit much faster – Phobos every 8 hours, Deimos every 30 hours; so well over 2,000 orbits per 30 day ‘month’ for Phobos and over 500 orbits per ‘month’ for Deimos. InSight landed Nov. 2018 on a two-year mission to better understand the interior of Mars using both surface and drilling geophysical sensors. Turning to night sky highlights this week: Mars, Jupiter, and Saturn have the morning sky at 6:00 a.m.; Venus has the evening at 6:00 p.m. We’re gaining 2.5 minutes of sunlight per day through March.
Efforts intensify to revive the Opportunity rover, silent on Mars since June 2018; the InSight lander deploys instruments to study the Martian interior at Elysium Planitia and New Horizons completes its successful flyby of Ultima Thule, the most distant object ever visited.
Hoy viajamos hasta Marte porque allí, en un paraje llano y desolado del ecuador que lleva por nombre Elysium Planitia, reposa la nave InSight de la NASA desde el pasado 26 de noviembre de 2018. En estos momentos la nave está poniendo a punto sus instrumentos, desplegando algunos, calibrando otros, preparándose para lo que será su objetivo fundamental: estudiar el interior del Planeta Rojo. Nuestro invitado, José Francisco Moreno, ha dirigido al estudio y desarrollo de instrumentos destinados a conocer las condiciones meteorológicas de Marte y es el ingeniero principal del instrumento TWINS, situado en InSight. El cometido de TWINS es, básicamente, medir el viento y la temperatura de Marte en el lugar de descenso y aportar información ambiental al conjunto de experimentos de InSight.
Tratamos los siguientes temas: - Caníbales cósmicos: los núcleos galácticos activos. - El gigante de la vía láctea: Sagitario A*. - Agujeros negros supermasivos. - El viaje de la Insight, desde casa a Elysium Planitia.
InSight , INterior Exploration using Seismic Investigations, Geodesy, and Heat Transport, launched on May 5th, 2018 and on Monday, November 26, 2018, NASA-JPL successfully landed InSight on the Elysium Planitia on Mars. The lander, because it won't be moving, has a lot of unique science it will be doing. I spoke with Emily Lakdawalla , the senior editor and planetary evangelist for the Planetary Society about the science and what we hope to uncover about Mars.
Marte tiene un nuevo habitante robótico: la sonda InSight de la NASA, que ayer logró superar el siempre problemático descenso de la atmósfera marciana y ya está posada en Elysium Planitia, una zona estable y plana desde la que llevará a cabo un estudio geológico y sismológico del interior del planeta rojo. En La Brújula os contamos los instantes posteriores al amartizaje con éxito de InSight. Si os interesa la exploración de Marte buscad los episodios s02e01, s06e11 y s06e45, en los que hablamos de las misiones Curiosity, Schiaparelli y sobre viajes tripulados al planeta rojo. En los capítulos s05e04, s07e48 y s02e08 hablamos también de otros descubrimientos relacionados con Marte. Este programa se emitió originalmente el 26 de noviembre de 2018.

Finally, after technical issues delayed the mission by 2 years, NASA's latest outpost on the red planet is safely established at Elysium Planitia. InSight will use a crane to deploy surface instruments to study Mars' interior, listen for marsquakes and drill several meters beneath the landing site with a heat probe.
