Kosmos 482: The Soviet-era Venus probe that fell to Earth

This week on Planetary Radio, we explore the decades-long journey of Kosmos 482, a Soviet-era Venus probe that spent 53 years orbiting Earth before its dramatic return on May 10, 2025. Ben Fernando, a postdoctoral researcher in seismology and planetary science at Johns Hopkins University, joins us to explain the history of Kosmos 482 and how seismology and acoustic sensors are helping scientists detect and locate objects impacting Earth. Then Bruce Betts, our chief scientist, joins us for What's Up, where we look back at the largest human-made objects ever to crash back to Earth.
