Summary
STS-70 launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39B, Kennedy Space Center, FL, USA on July 13, 1995. It was Lockheed Space Operations Company's 60th launch, 3rd this year and humanity's 4,000th orbital launch attempt. It was the 70th Space Shuttle flight and the 4th this year. The payload was bound for low Earth orbit (LEO). Discovery (STS-70), one of 4 catalogued objects, reached a 307 × 340 km orbit inclined 28.5°. 5 crew members flew: Terence Henricks, Nancy J. Currie-Gregg, Donald A. Thomas, Kevin R. Kregel and Mary Ellen Weber. The spacecraft was Space Shuttle Discovery (OV-103). 4 objects from this launch are catalogued, 2 of them payloads.

Spacecraft
Space Shuttle Discovery (OV-103)
Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9, having spent a cumulative total of almost a full year in space. Discovery performed both research and International Space Station (ISS) assembly missions. It also carried the Hubble Space Telescope into orbit. Discovery was the first operational shuttle to be retired, followed by Endeavour and then Atlantis.
- Destination: Low Earth Orbit
- Mission length: 8 days 22 hours
Space Shuttle Discovery successfully landed at the Shuttle Landing Facility after this mission.

About this launch
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.
