Discovery's 13-day mission is being called a success after astronauts undertook four space walks to install new wiring and to do battle with a recalcitrant solar panel. The next scheduled flight is the Atlantis shuttle in March. A video chronicle of the mission, including the landing, is available at NASA's video gallery."
