The Impact of Space Junk
Recent updates highlight concerns regarding a Soviet-era spacecraft, Cosmos 482, which has been in low Earth orbit since 1972 and is expected to crash land. Researchers predict potential landing zones that avoid populated areas but note the risk if the craft lands intact, which was designed for the extreme conditions of Venus. The spacecraft's uncontrolled descent raises questions about space debris management and the long-term implications of aging satellites in orbit. Observing this event underscores the broader issue of space junk, emphasizing the need for sustainable practices in space exploration to mitigate future risks.
