In 1972, the Soviet Union launched a pair of space probes destined for Venus. While the USSR’s Venera 8 successfully reached its destination, a malfunctioning Soyuz rocket ensured its sibling Kosmos 482 craft never made it past Earth’s orbit. Marco Langbroek posted about the impending reentry to his blog SatTrackCam Leiden on April 24. Based on calculation models co-designed by space engineer Dominic Dirkx, Kosmos 482 is due to begin its descent on or around May 10. It’s also possible that the Soviet space probe debris could burn up during atmospheric reentry, but that’s not entirely a given thanks to the probe’s original mission goals.
