Podcasts about asteroids

There's growing debate about the future of asteroid mining, as technology keeps making new advancements. These new developments have prompted concerns about how this process can be regulated, as it looks more likely asteroid mining will take off by the end of the decade. Waikato University Senior Lecturer in Law Anna-Marie Brennan says there's plenty to be mined from asteroids - and it will likely reduce the environmental impacts on Earth. "But at the same time, a lot of researchers, a lot of lawyers think we do need a monitoring mechanism for this activity." LISTEN ABOVESee omnystudio.com/listener for privacy information.

SpaceTime with Stuart Gary - Series 29 Episode 28In this episode of SpaceTime, we dive into the groundbreaking mapping of Uranus's upper atmosphere, the European Space Agency's innovative Planetary Defense Fly Eye Telescope, and NASA's critical findings on Boeing's Starliner spacecraft.Mapping Uranus's Upper AtmosphereA new study has successfully created a three-dimensional map of Uranus's upper atmosphere, revealing how the ice giant's unusual magnetic field influences its auroral activity. This detailed mapping, reported in Geophysical Research Letters, shows emissions from molecules located up to 5,000 kilometers above the cloud tops, confirming a cooling trend over the past 30 years. The research highlights the complex dynamics of Uranus's magnetosphere, which is tilted and offset, leading to unique auroral patterns unlike any other planet in our solar system.ESA's Fly Eye Telescope for Planetary DefenseThe European Space Agency is developing the Fly Eye Telescope, designed to detect Near Earth Objects (NEOs) that could pose a threat to Earth. Inspired by the compound eye of insects, this innovative telescope uses a unique design to scan vast areas of the sky efficiently, identifying potential impact risks. With plans for a network of these telescopes, ESA aims to enhance our capability to monitor and mitigate the dangers posed by asteroids and comets.Nasa's Scathing Robert on Boeing's StarlinerNASA has released a critical report detailing the failures of Boeing's CST-100 Starliner spacecraft, highlighting engineering vulnerabilities and internal mistakes that jeopardized crew safety. The investigation found Starliner less reliable for crew survival compared to other manned spacecraft, leading to a recommendation that no further crewed flights occur until all technical issues are resolved. The report underscores the need for stringent oversight in space missions to ensure astronaut safety.www.spacetimewithstuartgary.com✍️ Episode ReferencesGeophysical Research LettersSupport our podcast: Become a supporter.

Astronomy Daily — S05E55 | 6 March 2026 Six stories today covering planetary defence, a cosmic laser record, a solar superstorm on Mars, space debris pollution, a mystery satellite launch, and the most charming farming experiment you'll hear about all year.   Stories This Episode 1. Asteroid 2024 YR4 — Moon Impact Officially Ruled Out NASA has confirmed, using the James Webb Space Telescope, that infamous asteroid 2024 YR4 will not hit the Moon in 2032. The space rock — once the most dangerous asteroid identified in two decades — will instead pass the Moon at a distance of around 13,200 miles. It previously held a 4% lunar impact probability, now fully eliminated thanks to Webb's extraordinary sensitivity pushing it to the limits of what the telescope can observe.   2. MeerKAT Detects Cosmic 'Gigalaser' 8 Billion Light-Years Away South Africa's MeerKAT radio telescope has spotted the most distant hydroxyl megamaser ever detected — a natural 'space laser' in a galaxy undergoing a violent collision more than 8 billion light-years away. The signal is so powerful it qualifies as a gigamaser. Adding to the serendipity, the signal was further amplified by a foreground galaxy acting as a gravitational lens on its 8-billion-year journey to Earth. The discovery points toward the future capability of the Square Kilometre Array (SKA).   3. ESA's Mars Orbiters Record Solar Superstorm Hitting Mars A new Nature Communications study reveals what happened when the record-breaking May 2024 solar superstorm hit Mars. ESA's Mars Express and ExoMars Trace Gas Orbiter recorded unprecedented electron density spikes in the Martian upper atmosphere — up to 278% above normal — and both spacecraft experienced computer glitches from the energetic particles. The study uses a novel spacecraft-to-spacecraft radio occultation technique and highlights how Mars's lack of a global magnetic field leaves it vulnerable to solar events in ways that Earth is not.   4. SpaceX Falcon 9 Re-entry Directly Linked to Atmospheric Lithium Plume For the first time, scientists have directly tied a specific rocket re-entry to a measurable atmospheric pollution event. Researchers at the Leibniz Institute for Atmospheric Physics detected a tenfold spike in lithium vapour in the upper atmosphere — from 3 to 31 atoms per cubic centimetre — in the hours following the uncontrolled re-entry of a Falcon 9 upper stage off Ireland in February 2025. Eight thousand backward atmospheric simulations confirmed the connection. Published in Communications Earth & Environment, the paper raises important questions about the growing chemical footprint of the commercial space industry.   5. Rocket Lab Launches Mystery Satellite — 'Insight at Speed is a Friend Indeed' Rocket Lab completed its 83rd Electron launch from New Zealand, deploying a single satellite for a confidential commercial customer to an orbit 470 km above Earth. The company announced the mission just hours before liftoff, offering no further details on the customer or the payload's purpose.   6. Scientists Grow Chickpeas in Simulated Moon Dirt for First Time Researchers at the University of Texas at Austin and Texas A&M University have successfully grown and harvested chickpeas in simulated lunar regolith — the first time this has ever been achieved. Using a combination of vermicompost (worm castings) and arbuscular mycorrhizal fungi to condition the otherwise toxic, sterile moon dirt, the team produced flowering, seed-bearing plants in soil mixtures of up to 75% regolith simulant. The chickpeas have not yet been cleared for eating pending metal accumulation testing — but the team's goal of 'moon hummus' is, apparently, very much alive.   Find Us:  astronomydaily.io  |  @AstroDailyPod on all platforms Subscribe & Review:  Apple Podcasts · Spotify · YouTube · everywhere you listenBecome a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-space-news-updates--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

Earth's orbit is full of space junk like out-of-service satellites that completed their mission long ago. One study even estimated that 100 trillion pieces of space debris are floating outside the planet. Joel Sercel, CEO and Founder of TransAstra, shares insights on space debris capture technology that has the potential to make space more accessible and sustainable for future generations.

Without additional data, the true nature of the rapidly northward moving point of light my Catalina Sky Survey teammate Carson Fuls had just discovered would have remained a mystery. Fortunately, this new object was tracked by telescopes in both Arizona and New Mexico. These data were used to calculate it's orbit around the Sun, estimate it's size, and give it the name 2017 UX5. When Carson first spotted this enormous 1,200 foot diameter space rock it was more than 30 million miles away traveling in our direction at 10.7 mi/s. It's orbit and that of the Earth's nearly intersect and at the closest point they are about two and one half times the Moon's distance from us apart. An asteroid the size of 2017 UX5 impacts the Earth every 76,000 years or so. According to the impact calculator developed at Purdue University and the Imperial College of London if 2017 UK5 is made of porous rock and came in at an angle of 45 degrees, it would start to break into pieces at an altitude of 41 miles and upon reaching the surface would create a crater 2.2 miles in diameter and 5/8 of a mile deep in sedimentary rock. The results 20 miles away from impact would be that of a 6.4 Richter Scale magnitude Earth quake followed by 176 mph air wind blast which would blow down 90% of the trees and collapse wood frame buildings. Fortunately asteroid hunters have not discovered any object like Carson's discovery with our number on it.

Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We'll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

But the concept never truly disappears, and for good reason. Near-Earth asteroids, numbering in the millions, contain staggering quantities of precious metals, rare earth elements, and water ice. Ironically, those same materials — iron, gold, platinum, nickel, and dozens of others — were originally delivered to Earth by asteroids during the Late Heavy Bombardment period some four billion years ago. We're essentially talking about going back to the source. The three main asteroid types — carbonaceous (C-type), silicate (S-type), and metallic (M-type) — each offer distinct resources. Beyond metals, the abundance of water ice in the solar system could relieve pressure on Earth's increasingly stressed freshwater supply and fuel deep-space missions. Philosophically, the implications are profound. Thomas More and Nietzsche both wrestled with why scarcity drives human value systems. Flood the market with space-borne metals and the entire economic architecture built on scarcity begins to crumble. Orwell saw it too — abundance erodes hierarchy. The first trillionaires born from asteroid mining might find their wealth meaningless almost immediately after making it. But the darker scenarios deserve equal attention. Redistributing consumption off-world doesn't eliminate it. Space debris, environmental degradation beyond Earth, and the very real risk of exploitative labor structures in off-world operations — echoes of colonialism and indentured servitude — are not science fiction. They're logical extensions of human patterns. The enthusiasm may ebb and flow, but asteroid mining remains an inevitable chapter in humanity's story. The real question is what kind of story we choose to write around it. ______________________ Resources   ______________________ For more podcast Stories from Space with Matthew S Williams, visit: https://itspmagazine.com/stories-from-space-podcast Hosted by Simplecast, an AdsWizz company.

On Earth living things are everywhere from the deepest ocean depths to the highest mountain tops. On our home planet RNA (Ribonucleic Acid) is a complex essential molecule involved in the process of translating genetic information into the working components of living cells. In a recent paper in the peer reviewed scientific journal Proceedings of the National Academy of Sciences , Dr. Yuta Hirakawa and his team of two coauthors report on their experiments to produce RNA under conditions similar to those which may have occurred in the early history of Earth and Mars.

On the morning of June 30, 1908, something exploded over the remote Siberian wilderness with a force estimated at up to 15 megatons of TNT — flattening over 80 million trees across 800 square miles… and yet, leaving behind no crater. In this episode of Truth Be Told Paranormal, we dive deep into one of the greatest unsolved mysteries in modern history: The Tunguska Event. Was it a comet or asteroid that detonated in the atmosphere?A mini black hole passing through Earth?A secret Nikola Tesla experiment gone wrong?Alien technology malfunctioning mid-flight?Eyewitnesses reported a fireball streaking across the sky, followed by a shockwave so powerful it knocked people off their feet over 40 miles away. Windows shattered hundreds of miles from the blast site. The night skies across Europe glowed for days afterward — bright enough to read a newspaper at midnight. But with no impact crater, minimal physical debris, and delayed scientific investigation due to political turmoil in Russia, the Tunguska explosion has remained a breeding ground for conspiracy theories and alternative explanations for over a century. Tonight, we examine the science, the speculation, and the cover-up theories surrounding the largest atmospheric explosion ever recorded in human history — and ask the question: Was Tunguska truly a natural disaster… or something far more mysterious?Become a supporter of this podcast: https://www.spreaker.com/podcast/truth-be-told-paranormal--3589860/support.

To get an idea of the energy involved in a rocket launch, the NASA Saturn V, moon rocket, fully fueled on the launch pad contained the chemical energy of 2,000 pounds of TNT. This old technology could carry us to Mars and back on missions that would last years. To cut the mission time, the risks, and the mass of supplies required for such a prolonged space mission NASA is looking at alternative means of rocket propulsion. Back in the 1950s NASA's project Orion was a study to investigate propelling a rocket by a series of atomic bomb explosions behind the vehicle. Now a safer and more gentle way of propelling a space craft with nuclear fission is being studied as the result of a NASA grant to BWX Technologies. The concept is to heat liquid hydrogen using a high temperature fission reactor furnace which would expel the gas at a high velocity producing the rocket's thrust. The process would be about twice as efficient in terms of thrust per pound of fuel when compared to burning a hydrogen and oxygen mixture. Since it is unacceptable to release trace amounts of radioactivity in the rocket's exhaust, engineers are investigating a technique developed by NASA in which the hydrogen exhaust is burned with oxygen to produce water which can be caught and decontaminated. Don't expect to buy a round trip ticket on a high speed fission powered rocket any time soon. However, in the long run nuclear technology could revolutionize the exploration and colonization of our solar system.

In April 2029 on one of the luckiest Friday the 13th in human history the 1500 ft by 500 ft asteroid Apophis will pass within 23,600 miles of the Earth's surface traveling at some 4.6 mi/s. This is extremely fortunate since an Apophis impact would release the energy of scores of nuclear weapons and cause wide spread devastation. NASA's OSIRIS-APEX will become the companion of the potentially hazardous asteroid Apophis on 5 June 2029,

Eighteen hours before my Catalina Sky Survey teammate Rose Matheny first spotted a small space rock with our Schmidt telescope on Mt. Bigelow, Arizona it had passed less than the Earth's diameter from the surface of our planet. Rose was able to discover this Smart Car sized space rock after it moved out of the Sun's glare. At this point it was about the Moon's distance from her and was traveling away at 3.4 mi/s. After Rose posted her discovery observations on the Minor Planet Center's Near Earth Object Confirmation page, for the next 24 hours it was tracked by telescopes in Spain, Illinois, and Arizona. Scientists at the Minor Planet Center used these data to calculate it's orbit around the Sun, estimate it's size and give it the name 2017 UJ2. This small asteroid had come near the Earth in 1978 but was invisible to the technology which astronomers had available at the time. 2017 UJ2 will not come close enough for us to detect in the foreseeable future, however, there are likely to be tens of millions of others like it which can come close to Earth. A small asteroid the size of Rose's discovery is likely to enter our atmosphere at least once a year and explodes at about 4 times higher than airliners fly. If such an event happened at night and you were lucky enough to see it you would be treated to a fantastic light show. If you are as lucky as a power ball winner you might even be able to find a piece of it on the ground.

Professor Dante Lauretta discusses his book The Asteroid Hunter and his early career at the University of Arizona's Lunar and Planetary Laboratory, recalling how mentor Mike Drake and Lockheed Martin recruited him in 2004 for a daring asteroid sample return mission despite early rejections.

Dante Lauretta describes how upon reaching asteroid Bennu the team found a hazardous rocky surface instead of expected sand, detailing the difficulty selecting the Nightingale landing site where the spacecraft sank into fluid-like material, collecting so much the container began leaking.R

We've reached the conclusion of our year-long project with the kid from Texas. But first, a little look back at ASTEROID CITY before a collective filmography ranking.

Bob Zimmerman covers ESA's fast-tracked Apophis asteroid mission, a commercial attempt to rescue a NASAtelescope, and the contrasting regulatory environments of the UK and New Zealand for space launches.

The Earth's atmosphere does a good job of protecting humanity from space weather, however, occasionally a major event does break through our shield and gets our attention. Tree rings and ice cores have recorded past space weather events thousands of time larger than which have occurred in the modern age. investing in research seems wise.

Science fiction became science fact in 2022 when NASA's DART mission took the first steps towards creating a planetary defence system that could someday protect Earth from a catastrophic asteroid collision. However, much more work on asteroid deflection is needed from the latest generation of researchers – including Rahil Makadia, who has just completed a PhD in aerospace engineering at University of Illinois at Urbana-Champaign. In this episode of the Physics World Weekly podcast, Makadia talks about his work on how we could deflect asteroids away from Earth. We also chat about the potential threats posed by near-Earth asteroids – from shattered windows to global destruction. Makadia's stresses the importance of getting a deflection right the first time, because his calculations reveal that a poorly deflected asteroid could return to Earth someday. In November, he published a paper that explored how a bad deflection could send an asteroid into a “keyhole” that guarantees its return. But it is not all gloom and doom, Makadia points out that our current understanding of near-Earth asteroids suggests that no major collision will occur for at least 100 years. So even if there is a threat on the horizon, we have lots of time to develop deflection strategies and technologies.

In an area which is about 1/400th of the entire sky, the NASA Kepler spacecraft has discovered 30 Earth like planets which are likely to have liquid water on their surfaces orbiting distant stars. These planets are likely to represent a tiny sample of the habitable planets which exist in the Milky Way. In spite of our efforts to find them, the question remains where are the alien civilizations? In a recent talk given at the Division of Planetary Sciences meeting Dr. Alan Stern of the Southwest Research Institute suggests that perhaps the majority of worlds with biology and intelligent civilizations exist on interior water ocean worlds where their existence is hidden by the thick layers of rock and ice which separate them from the hostile vacuum of space. We know that in our solar system alone the moon of Jupiter Europa, Saturn's moon Enceladus, and perhaps several other small worlds are likely to have oceans of nutrient rich liquid water covered by a thick layer of rock and ice. We also know that Whales and Dolphins have larger brains than humans, communicate with each other, and exhibit other forms of intelligence. Advanced civilizations existing in ice covered seas may know little of the greater Universe, may find it difficult to consider transporting enough water to travel beyond their worlds, and may not think that it is possible to communicate with others of their kind who are similarly hidden under miles and miles of radiation absorbing ice and rock.

Around the world those who value the natural night sky are evaluating the effects of light pollution. In addition to impairing astronomy and star gazing the past 100 years of increasing light pollution is proving to be harmful to human health and the natural world upon which we all depend. The purpose of the Dark Sky Network is monitor and facilitate the mitigation of the harmful effects of light pollution.

There's always been a fuzzy line between asteroids and comets, and new observations of asteroids in the vicinity of Jupiter provide a hint to the origin of the mysterious active asteroids that look like asteroids but act like comets. Elsewhere in the galaxy, the famous ring nebula gets a new spectral image that shows the presence of band of iron. Could it be the remnants of a planet like Earth or Mercury that was vaporized when the nebular formed? Tune in for our take on this, space news, trivia and much more.

In this episode of SpaceTime, we explore new insights into the origins of Earth's water, groundbreaking discoveries beneath the surface of Jupiter's volcanic moon Io, and how tectonic plate movements may have influenced Earth's climate throughout history.New Clues on Earth's Water OriginsA recent study published in the Proceedings of the National Academy of Sciences reveals that asteroid and comet impacts could only account for a small fraction of Earth's water supply. By analyzing oxygen isotopes in lunar regolith collected during the Apollo missions, researchers found that the early Earth likely retained little to no water during its formative years. This challenges long-held beliefs and suggests that the majority of Earth's water must have originated from other sources, rather than being delivered by celestial bodies.Unprecedented Volcanic Activity on IoNASA's Juno spacecraft has captured remarkable data on Io, the most volcanically active body in our solar system. Observations from a December flyby revealed the most energetic eruption ever detected on Io, affecting a vast area of 65,000 square kilometers. The findings indicate that interconnected magma reservoirs beneath Io's surface are responsible for this extraordinary volcanic activity, providing new insights into the moon's geological dynamics and evolution.Tectonic Plates and Earth's ClimateA new study suggests that carbon released from shifting tectonic plates may have played a significant role in Earth's climatic transitions, rather than volcanic activity as previously thought. Researchers reconstructed carbon movements over the last 540 million years, providing evidence that carbon emissions from mid-ocean ridges were the primary drivers of climate shifts between ice ages and warmer periods. This research reshapes our understanding of past climate dynamics and offers valuable insights for future climate models.www.spacetimewithstuartgary.com✍️ Episode ReferencesProceedings of the National Academy of SciencesJournal of Geophysical Research PlanetsCommunications Earth and EnvironmentBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.
