The crew of Discovery has begun its last day of joint operations with the International Space Station.

Crew members were awakened at 3:32 a.m. CDT by "All Because of You," performed by U2. It was played for Mission Specialist Ron Garan.

The crew will spend the morning configuring a backup drive for the Kibo laboratory’s robotic arm. The astronauts also will be enjoying a couple of hours of off-duty time today after several busy days on orbit.

International Space Station Flight Engineer Greg Chamitoff and Discovery Mission Specialist Garrett Reisman (whom Chamitoff replaced as a station crew member) will speak with NBC News, KGO Radio and Fox News Radio this afternoon. Those interviews will air live on NASA TV at 1:10 p.m.

At 2:57 p.m. CDT, the crews of Discovery and Expedition 17 are due to say goodbye to each other. Hatches between the two spacecraft will be closed shortly thereafter.

Crew members will do a series of leak checks before going to sleep for the evening. Discovery's crew begins its sleep period at 7:02 p.m.

Undocking from the International Space Station is set for Wednesday at 6:42 a.m.
