(00:00:00) Theia Unveiled: Tracing the Origins of Earth's Moon and Lucy's Journey to Jupiter's Trojans (00:00:50) New study claims Theia and Earth were once neighbours (00:06:16) Lucy’s mission to Jupiter’s trojan asteroids (00:15:26) Starliner’s next mission to be limited to cargo only (00:17:57) The Science Report (00:23:17) Alex on Tech: Dooms Day clock countdown to Digital ID In this episode of SpaceTime, we dive into the intriguing origins of our Moon and the latest developments in space exploration.Theia: The Lost Planet Behind the Moon's BirthA groundbreaking study reveals that Theia, the small planet believed to have collided with Earth to form the Moon, originated from the inner solar system. Researchers from the Max Planck Institute and the University of Chicago have analyzed isotopic compositions of Earth and Moon rocks, suggesting that Theia was likely composed of materials found closer to the Sun than Earth's orbit. This discovery sheds light on the nature of this celestial body and its dramatic impact on our planet's history.Lucy Mission Update: Journey to Jupiter's TrojansNASA's Lucy spacecraft, launched in October 2021, is on an ambitious 12-year mission to explore Jupiter's Trojan asteroids. These ancient remnants from the solar system's formation are crucial for understanding planetary development. Lucy will visit seven asteroids, including both leading and trailing Trojan swarms, providing unprecedented insights into the early solar system. Principal Investigator Hal Levison emphasizes that the mission will revolutionize our understanding of planetary formation and the origins of volatiles and organics on terrestrial planets.Starliner Mission Limited to CargoIn a significant setback, NASA has announced that Boeing's Starliner spacecraft will only carry cargo on its next mission to the International Space Station. This decision follows a series of technical issues that plagued Starliner's previous flights. With the total number of planned missions reduced from six to four, NASA aims to ensure safety and reliability before allowing crewed flights again.www.spacetimewithstuartgary.com✍️ Episode ReferencesJournal of ScienceNASA ReportsMax Planck Institute StudiesBecome a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.
