Space shuttle Discovery decamped from the international space station Saturday to begin a return trip back to Earth.
The shuttle, which arrived at the station ten days ago, is due back on Earth Monday to conclude only the second mission since the 2003. It is scheduled to land at the John F. Kennedy Space Center in Florida on Monday, but NASA is planning for a possible landing at Edwards Air Force Base in California because of the power unit issue.
Good return flight.
