The Astronomy, Space and Science News Podcast
Asteroid Impact Odds, Lunar Grand Canyons, and NASA's Stranded Astronauts
In this episode of SpaceTime, we discuss the alarming increase in the odds of asteroid 2024 YR4 impacting Earth, now estimated at 3.1% for December 22, 2032. This asteroid, measuring between 40 to 90 meters, poses a significant threat, and we delve into the implications of planetary defense strategies that could be employed to mitigate this risk.
The Origins of the Moon's Grand Canyons
We also explore new research that suggests the Moon's massive canyons, Vallis Schrodinger and Valles Plank, were carved out by asteroid impacts in a mere 10 minutes. This groundbreaking study provides insights into the Moon's geological history and will have important implications for future lunar missions, particularly the upcoming Artemis program.
NASA's Stranded Astronauts
Additionally, we cover the latest developments regarding NASA astronauts Sunita Williams and Butch Wiltmore, who have been stranded aboard the International Space Station since June 2024. With the potential for an earlier return home due to a change in SpaceX's Crew 10 mission schedule, we discuss the challenges they faced during their extended stay in orbit.
