Kosmos 482 Unexpectedly Re-Entry the Earth After 53 Years in Orbit
A relic of the Cold War space race has met its fiery end after being lost in space for over half a century. Its composition and original purpose made its return an event that raises concerns about potential ground impact and international responsibility.
On May 10, 2025, the Kosmos 482 probe, a failed Soviet Venus lander stranded in Earth’s orbit for over half a century, re-entered the Earth’s atmosphere. Data says the titanium part of the lander impacted somewhere over the eastern Indian Ocean about 248 miles (560 km) west of Middle Andaman Island and west of Jakarta, Indonesia.
Launched on March 31, 1972, from Baikonur Cosmodrome in what is now Kazakhstan, Kosmos 482 was a part of the Soviet Union’s Venera project, intended to explore the harsh environment of Venus.
However, a rocket malfunction shortly after launch caused the space to break up and prevented it from reaching its intended trajectory. This malfunction left a significant part of the spacecraft in orbit, including the Venus lander capsule, a particularly robust piece of hardware.
The lander capsule is a meter-wide, 1,091-lb (495-kg) sphere made from titanium, designed to withstand deceleration forces of 300 g upon atmospheric entry and then survive for over an hour on the surface of Venus, where not only sulfuric acid rains, but the atmosphere is also 90 times as dense as Earth’s.
These design specifications meant the capsule had a significant probability of surviving Earth’s atmospheric re-entry and impacting the ground at a considerable speed, potentially causing damage.
In addition, as Russia still has legal ownership of the spacecraft under international law, it would also have resulted in a very large bill for them for any damage caused by the capsule’s impact.
The probe’s re-entry was tracked by various agencies, including Roscosmos, the European Space Agency (ESA), and the US Space Force, as well as independent space trackers. Images were captured that seem to not only confirm that this was the capsule, but also suggested deployment of its landing parachute. However, after decades of exposure to cosmic radiation, the parachute’s integrity was likely compromised, rendering it largely ineffective.
ESA’s radar tracking station in Germany reports it failed to detect the spacecraft during a predicted pass at 07:32 GMT, while Roscosmos claimed to have observed it striking the lower atmosphere.
