Last crew pic of STS133 and ISS crews together.
The shuttle Discovery undocked at 5 am EST this morning and pulled away from the station at around 6:30. This was Discovery's last trip to the ISS and into space. It will be retired barring some unexpected act of Congress.
The crews were shaken from their slumber this morning with the playing of the "Theme from Star Trek" and personally narrated by WIlliam Shatner, the iconic actor who played Captain Kirk on the classic series as well as 6 of the movies.
The Discovery crew will perform safety checks including another robotic arm-camera inspection of the re-entry tiles. They are scheduled to land on Wednesday.
