Failed Soviet Probe Plunges Back to Earth After 53 Years Stuck in Orbit
A spacecraft that got stuck in Earth orbit after a failed attempt to travel to Venus more than 50 years ago has finally returned to Earth. Kosmos 482, the last remnant of the Soviet Venus exploration program, plunged on an uncontrolled reentry back into Earth's atmosphere on 10 May 2025, just over 53 years after it was dispatched on its mission on 31 March 1972. Because Kosmos 482 was built to withstand conditions on Venus – scorching temperatures averaging 464 °C (867 °F), acid rain, and crushing atmospheric pressure – scientists had hypothesized that the 495-kilogram (1,091-pound) lander might at least partially survive atmospheric entry. However, according to Russia's government space agency, the spacecraft probably fell into the ocean. Which would be unsurprising, given that some 71 percent of Earth's surface is covered by water. "The Kosmos-482 spacecraft, launched in 1972, ceased to exist, deorbiting and falling into the Indian Ocean," Roscosmos wrote in a Telegram post on May 10. "According to calculations by specialists from TsNIIMash (part of Roscosmos), the spacecraft entered the dense layers of the atmosphere at 09:24 Moscow time [06:24 UTC], 560 kilometers west of Middle Andaman Island, and fell into the Indian Ocean west of Jakarta." Astronomer Marco Langbroek of SatTrackCam Leiden, a satellite tracking facility in the Netherlands, says some uncertainty remains about Kosmos 482's final resting place, since the Roscosmos calculations are not based on observation, but modeling. However, the European Space Agency estimates the time of entry at 06:16 UTC, and the Technical University of Denmark estimates it at 06:40 UTC. The Roscosmos estimate sits nicely in the middle of the two estimates. The Indian Ocean, Langbroek says, is the most likely place for the spacecraft to have splashed down. We won't know for sure until more data is in. For now, we'll just have to settle for knowing that it did come down, and didn't land in a place where it's going to cause any problems, which is a nice win for humanity, all things considered.

Soviet spacecraft plunges to Earth after 50 years stuck in space
A Cold War-era spacecraft has come crashing down to Earth after being stuck in orbit for more than five decades. An unconfirmed report from Russian space agency Roscosmos claimed that the Kosmos 482 splashed down in the Indian Ocean, west of Jakarta. Experts from around the globe had been monitoring Kosmos 482, but its eccentric orbit, coupled with space weather, made its potential landing site difficult to predict. In an update on its Telegram channel, Roscosmos said: 'The descent of the spacecraft was monitored by the automated warning system for hazardous situations in near-Earth space. 'According to calculations by specialists from TsNIIMash [part of Roscosmos], the spacecraft entered the dense layers of the atmosphere at 9.24 Moscow time, 560 kilometres west of Middle Andaman Island, and fell into the Indian Ocean west of Jakarta. 'The spacecraft was launched in the spring of 1972 to study Venus, but due to a malfunction of the booster block, it remained in a high elliptical orbit of the Earth, gradually approaching the planet.' Both the EU Space Surveillance and Tracking Operations Centres and the US Space Command have been monitoring the probe after it suffered a rocket malfunction and ended up trapped in orbit around Earth for 53 years. The European Space Agency (ESA) space debris office had calculated that the craft would 'come down at a point between 52 degrees north and 52 degrees south of the equator'.
