Russian satellite breaks up in space, forces ISS astronauts to shelter

WASHINGTON (Reuters) -A defunct Russian satellite has broken up into more than 100 pieces of debris in orbit, forcing astronauts on the International Space Station to take shelter for about an hour and adding to the mass of space junk already in orbit, U.S. space agencies said. There were no immediate details on what caused the break-up of the RESURS-P1 Russian Earth observation satellite, which Russia declared dead in 2022. U.S. Space Command, tracking the debris swarm, said there was no immediate threat to other satellites.
