STS-51-D was the 16th flight of NASA's Space Shuttle program, and the fourth flight of Space Shuttle Discovery. [2] The launch of STS-51-D from Kennedy Space Center (KSC), Florida, on April 12, 1985, was delayed by 55 minutes, after a boat strayed into the restricted Solid Rocket Booster (SRB) recovery zone. STS-51-D was the third shuttle ...
The Shuttle Training Aircraft (STA) is a former NASA training vehicle that duplicated the Space Shuttle's approach profile and handling qualities, allowing pilots to simulate Shuttle landings under controlled conditions before attempting the task on board the orbiter. The STA was also flown to assess weather conditions just prior to Space ...
The original intention was to compensate for this lower payload by lowering the per-launch costs and a high launch frequency. However, the actual costs of a Space Shuttle launch were higher than initially predicted, and the Space Shuttle did not fly the intended 24 missions per year as initially predicted by NASA.

Edwards Air Force Base in California was the site of the first Space Shuttle landing and became a backup site to the prime landing location, the Shuttle Landing Facility at the Kennedy Space Center. Several runways are arrayed on the dry lakebed at Rogers Dry Lake, [6] and there are also concrete runways. Space shuttle landings on the lake bed ...

The orbiter always landed at either Edwards Air Force Base, California or at the Kennedy Space Center Shuttle Landing Facility, Florida, except STS-3 at the White Sands Space Harbor in New Mexico. Similar special clearances (no-fly zones) were also in effect at potential emergency landing sites, such as in Spain and in West Africa during all ...
With an overall length of about 29 feet (8.8 m) and wingspan of 23.5 feet (7.2 m), the HL-20 would be a much smaller craft than the Space Shuttle Orbiter; it could fit within the payload bay of the Shuttle with wings folded. Projected empty weight of the HL-20 was 23,000 pounds (10 t) compared to the Space Shuttle Orbiter's empty weight of ...
