Overview

  • Kosmos-482, launched in 1972 by the Soviet Union, failed to leave Earth orbit due to a rocket malfunction and has been gradually descending for over 50 years.
  • The descent capsule, weighing 495 kg, was built to endure Venus's harsh conditions, making it likely to survive reentry and potentially impact Earth intact.
  • Experts predict the reentry will occur between May 7 and 13, most likely around May 10, with the capsule traveling at approximately 100–200 mph upon impact.
  • The capsule could land anywhere between 51.7° N and 51.7° S latitude, with oceans being the most probable landing site due to Earth's geography.
  • While the statistical risk of injury or damage is extremely low, any harm caused would make the Russian government liable under international space law.
