A Soviet Venus probe, Kosmos 482, is expected to re-enter Earth's atmosphere this week. Launched in 1972, it's the last remaining piece of the USSR's Venus program in Earth orbit. Unlike most space debris, its titanium lander, designed to withstand Venus' harsh conditions, may survive re-entry. Its re-entry is uncontrolled, raising concerns, although its potential impact is uncertain. The incident highlights growing concerns about space junk and its environmental impact.
