Kosmos 482, a Soviet spacecraft launched in 1972, is making headlines as it prepares to reenter Earth's atmosphere between May 10 and 13, 2025. This event raises questions about the spacecraft's history, the risks involved, and what happens during reentry. Here’s everything you need to know about this significant moment in space history.

What is Kosmos 482 and why is it reentering Earth?
Kosmos 482 is a Soviet spacecraft that was launched on March 31, 1972, as part of the Venera program aimed at exploring Venus. Due to a rocket malfunction, it has been stranded in Earth's orbit for over 50 years. It is now expected to reenter Earth's atmosphere, with experts predicting a descent between May 10 and 13, 2025.

What are the risks associated with the reentry of Kosmos 482?
Experts have assessed that the risk to people from Kosmos 482's reentry is minimal. The likelihood of injury is comparable to that of a random meteorite fall, according to Dr. Jonathan McDowell. While the spacecraft may crash at speeds of 150 mph, the chances of it causing harm to individuals on the ground are very low.
-
How often do spacecraft reenter Earth's atmosphere?
Spacecraft reenter Earth's atmosphere regularly, with many satellites and space debris falling back to Earth each year. However, most of these reentries occur without incident, as they often burn up upon reentry or land in uninhabited areas. Kosmos 482's reentry is notable due to its historical significance and the fact that it has been in orbit for over five decades.
-
What happens to spacecraft during reentry?
During reentry, spacecraft experience extreme temperatures and pressure as they descend through the atmosphere. Kosmos 482 is equipped with a titanium heat shield designed to withstand these conditions, increasing the likelihood that it may survive the reentry intact. The spacecraft's trajectory is being closely monitored to predict its potential impact zone.
-
What is the historical significance of Kosmos 482?
Kosmos 482 serves as a reminder of the Soviet Union's ambitious space program during the Cold War. Its launch was part of the Venera program, which aimed to explore Venus. The upcoming reentry marks a bittersweet moment in space history, as it symbolizes the end of an era for a spacecraft that has remained in orbit for over 50 years.
-
How are experts monitoring Kosmos 482's reentry?
Experts are using various tracking systems to monitor Kosmos 482's trajectory as it descends towards Earth. This involves calculating its speed, altitude, and potential impact zone to ensure public safety and provide updates on the reentry process. Continuous monitoring allows for timely information regarding the spacecraft's descent.
