Podcasts about asteroids

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From August 2025. Today's 2 topics: - In a recent study Dr. Lynnane George and her co-authors investigate Space Elevator technology to remove materials from Ceres and deliver them to orbital depots around the solar system. The tiny gravity of Ceres, nano-fiber technology, and different water propulsion systems are utilized by Dr. George and her team to construct theoretically possible systems which would extract raw materials from Ceres and deliver them to low Earth orbit and other locations within the solar system. These researchers estimate such a transport system could reduce fuel costs by up to 60% compared to transport from the Earth's surface.   - Asteroid 2024 YR4 will not hit the Earth in 2032, has a 4% chance of hitting the Moon, and most likely will pass within 900 miles of the lunar surface. If 2024 YR4 were to impact the Moon it could send about the mass of several small cargo ships into space with lunar escape velocity and could pose a threat to our satellites. [Editor's note: Using JWST data, it's just been calculated to miss the Moon, unfortunately.

Astronomers using the 8.1 m Gemini South Telescope in Chile were excited by the fact that 467P (LINEAR-Grauer)'s Centaur like orbit had been changed as the nucleus emitted rocket like bursts of gases as it was warmed by the Sun. Inert inactive asteroids orbit the Sun following the law of gravity whereas active asteroids can emit little rocket like bursts of gas which can change their path about the Sun in interesting ways. It is important to study objects like 467P (LINEAR-Grauer) to make sure their path about the Sun doesn't change to make them a threat to our home planet.

Once every 1,435 days , a 780 foot diameter space rock that my Catalina Sky Survey teammate Carson Fuls discovered makes an annihilation defying close approach to our star. At it's nearest point to the Sun, Carson's well done space rock is traveling at an amazing 93 miles per second and receives 26 times the amount of solar radiation that heats the surface of the planet Mercury to 800F. After Carson first discovered his heat resistant space rock traveling towards it's next hot date with the Sun, it was observed by telescopes in New Mexico, Arizona, Hawaii, and England. These data allowed scientists at the Minor Planet Center to calculate it's orbit around the Sun, estimate it's size, and give it the name 2017 TC1. 2017 TC1 crosses the orbits of Mars, Earth, Venus, and Mercury and can come relatively close to Jupiter on it's extremely elliptical orbit about the Sun. It is possible that in the very distant past the giant planet Jupiter's pull on 2017 TC1 sent it on it's current path around the Sun. In September of 2021, 2017 TC1 will once again be bright enough for asteroid hunters to track as it makes another close approach to our Sun. At this time astronomers with be able to measure the pattern of colors that 2017 TC1 reflects which will reveal it's surface chemical composition. Until then we are left to wonder how it is possible for a space rock to survive on such a harrowing path.

A rare, early-season tornado in Michigan was the strongest to hit the state since 1977, and left four dead, including a 6th grader. Also, meteorological winter runs from the start of December through the end of February, but that's not true for the coldest part of the year in many places. Plus, NASA on Thursday walked back a prediction that an asteroid had a "small, but notable" chance of impacting Earth or the moon in 2032 based on newly analyzed data.

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.

In 1892 the world's largest telescope, the Lick Observatory's 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome.The adaptive optics research pioneered at Lick Observatory helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii.

A key question about the early history of the Solar System is whether the giant planets formed roughly at the distances from the Sun they presently occupy, or, as some theories predict, much closer to the Sun. The discovery of other solar systems with radically different configurations of planets has made this question more pressing, since it appears that the configuration of the Solar System might be atypical. In the podcast, Hal Levison explains why the Trojan asteroids of Jupiter offer us the best opportunity to discriminate between the various models of Solar System evolution. And that is why a spacecraft called Lucy is now well on its way to a rendezvous with these asteroids. Hal Levison is the Principal Investigator of the Lucy mission. He studies the dynamics of astronomical objects and, in particular, the formation and long-term behavior of solar system bodies. He is one of the original proponents of the Nice model (named after the city where it was conceived), a scenario that proposes the migration of the giant planets from an initial compact configuration closer to the Sun to their present positions. He is Chief Scientist in the Department of Space Sciences at the Southwest Research Institute in Boulder, Colorado.

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.

When raised lead levels were noticed in Los Angeles last year, Professor Francois Tissot, who usually examines the chemistry of asteroids, quickly saw that the fires that ravaged the region in January 2025 were to blame. He reveals the current extent of the concern and suggests Australia inspects its own burned regions too. Guest Francois Tissot Professor of geochemistry Caltech PresenterRobyn Williams

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. Guests: Scott Sandford - Astrophysicist and Research Scientist at NASA's Ames Research Center Robin George Andrews - Science journalist, volcanologist, and author of "How to Kill an Asteroid: The Real Science of Planetary Defense" Descripción en español Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.

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.

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

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.

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.
