SpaceTime Series 27 Episode 151
*A New Perspective on the Moon's Aitken Basin
Recent observations of the Moon's south pole reveal that the Aitken Basin crater is more circular than previously believed. This significant discovery challenges existing theories about its formation and has implications for future lunar missions, including NASA's Artemis program. The study, published in Earth and Planetary Science Letters, suggests a more direct impact created the crater, offering potential access to deep lunar material for study.
*Gravitational Wave Maps Unveil Hidden Cosmic Structures
Astronomers have developed the most detailed gravitational wave maps yet, revealing hidden black holes and cosmic structures. Using pulsar timing arrays, researchers have detected a background of gravitational waves across the universe. This groundbreaking research, reported in the Monthly Notices of the Royal Astronomical Society, opens new avenues for understanding galactic evolution and the universe's history.
*NASA's First Aircraft Accident Investigation on another planet
NASA has conducted its first aircraft accident investigation on another planet following the crash of the Mars Ingenuity helicopter. The investigation revealed that the helicopter's navigation system struggled with the featureless Martian terrain, leading to a hard landing. Despite the crash, Ingenuity continues to provide valuable data for future Mars missions.
