Discovery Prepares for Return

Kailash Nadh writes "Discovery's astronauts packed up their stuff on Friday as they prepared to undock from the international space station now that NASA has cleared the shuttle to return to Earth next week. Their most difficult task before leaving the station was the maneuvering of a huge cargo container filled with 2 1/2 years worth of trash into the shuttle's payload bay. Once back on Earth, the items would either be disposed of or returned to researchers."
