Debris may be on collision course with space lab: NASAWashington (AFP) July 10, 2011 NASA is tracking a piece of Soviet space debris that could collide with the International Space Station, the US space agency said Sunday after the shuttle Atlantis docked on its final mission. The space junk is part of Cosmos 375, a satellite launched in 1970 by the former Soviet Union and which collided with another satellite and broke apart, but details about the size and exact trajectory of the object were unknown, NASA said. However, the debris could be on a collision course with the station ... read more |
