The Tracking and Data Relay Satellite (TDRS) project has put 10 satellites into Earth's orbit since 1983, one of which was destroyed in the Challenger shuttle disaster. Boeing is under contract to build two modern, third-generation satellites. TDRS K is scheduled to launch in 2012, and TDRS L in 2013. Credit: NASA
