On 29 November 2011, the U.S. Air Force announced that it would extend USA-226 beyond the 270-day baseline duration. [69] In April 2012, General William L. Shelton of the Air Force Space Command declared the ongoing mission a "spectacular success". [70] On 30 May 2012, the Air Force stated that the X-37B would land at Vandenberg AFB in June 2012.

The Air Force expected to use the Space Shuttle to launch large satellites, and required it to be capable of lifting 29,000 kg (65,000 lb) to an eastward LEO or 18,000 kg (40,000 lb) into a polar orbit. The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay.
The first flight began on April 22, 2010, and saw the first X-37B remain in orbit for a total of 224 days. The second flight, which was the second X-37B's inaugural mission, began on March 5, 2011 ...
The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA.
This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit. A first list contains rockets that are operational or have attempted an orbital flight attempt as of 2024; a second list includes all upcoming rockets.
Space (regardless of outcome): Flights which reach approximately 100 km or more above Earth's surface. Any orbit (regardless of outcome): Flights which achieve at least one complete orbit even if the orbit differs from the targeted orbit.
STS-48 was a Space Shuttle mission that launched on September 12, 1991, from Kennedy Space Center, Florida. The orbiter was Space Shuttle Discovery on her 13th flight. The primary payload was the Upper Atmosphere Research Satellite (UARS). The mission landed on September 18 at 12:38 a.m. EDT at Edwards Air Force Base on runway 22.
