The space shuttle Discovery left the International Space Station behind having done everything it was scheduled to do and more. It is set to land Wednesday.
Two space walks are scheduled for Monday. With craft from Russia, Europe, and Japan at the International Space Station as well, Discovery's last mission may include a unique photo op.
One day into the final mission for the space shuttle Discovery, the orbiter's systems were 'in great shape.' But the craft's heat-shedding tiles were closely inspected for post-launch damage.
