An initial orbital test flight of the Dream Chaser orbital test vehicle was planned for 1 November 2016, [43] which was not met. On 3 February 2015, the Sierra Nevada Corporation's (SNC) Space Systems and OHB System AG (OHB) in Germany announced the completion of the initial Dream Chaser for European Utilization (DC4EU) study.

The USSR copied the US's reusable Space Shuttle orbiter, which they called Buran-class orbiter or simply Buran, which was designed to be launched into orbit by the expendable Energia rocket, and was capable of robotic orbital flight and landing. Unlike the Space Shuttle, Buran had no main rocket engines, but like the Space Shuttle orbiter, it ...
The Spacefacts list includes most flights listed here, but omits twelve: The three failed launches of STS-51-L, Soyuz T-10a and Soyuz MS-10, none of which achieved human spaceflight, the uncrewed launch of Soyuz 34 (which nevertheless returned a crew to Earth), and the eight sub-orbital human spaceflights: Mercury-Redstone 3 and 4, X-15 flights ...
Tracking vehicles in low Earth orbits (LEO) is quite different from tracking deep space missions. Deep space missions are visible for long periods of time from a large portion of the Earth's surface, and so require few stations (the DSN uses only three, as of February 20, 2010). These few stations, however, require the use of huge antennas and ...
The Air Force Space Surveillance System (AFSSS), also known as the "space fence", was a very high frequency radar network located at sites across the southern United States (from California to Georgia) with a centralized data processing site at the Naval Network and Space Operations Command in Dahlgren, Virginia. AFSSS began as the Navy's Space ...
The flight was designed to be controlled from the ground via the Manned Space Flight Network, a system of tracking and communications stations; back-up controls were outfitted on board. Small retrorockets were used to bring the spacecraft out of its orbit, after which an ablative heat shield protected it from the heat of atmospheric reentry .
It complemented the geosynchronous Defense Support Program, the Space-Based Infrared System, and other overhead non-imaging infrared (ONIR) systems [15] [16] and provided tracking cues to systems on the surface. The STSS program was developed in phases, the first of which was the launch of two demonstrator satellites.
First human spaceflight from the State of New Mexico. Reached an altitude of 89.24 km (55.45 mi), crossing the U.S. definition of space, but not the FAI's definition. 331 Nie Haisheng (3) Liu Boming (2) Tang Hongbo (1) 17 June 2021 Shenzhou 12: TSS: 17 September 2021 Shenzhou 12: First crew to Tiangong Space Station. — David Mackay Michael ...
