STS-70 was the 21st flight of the Space Shuttle Discovery and the last of 7 shuttle missions to carry a Tracking and Data Relay Satellite (TDRS). This was the first shuttle mission controlled from the new mission control center room at the Johnson Space Center in Houston. STS-70 was also the first flight of the new Block 1 orbiter main engine designed to improve both engine performance and safety.
