One antenna was located in the Shuttle's payload bay, the other – a critical change from the SIR-C/X-SAR, allowing single-pass interferometry – on the end of a 60-meter (200-foot) mast that extended from the payload bay once the Shuttle was in space. [2] The technique employed is known as interferometric synthetic aperture radar.
STS-99 was a Space Shuttle mission using Endeavour, that launched on 11 February 2000 from Kennedy Space Center, Florida. The primary objective of the mission was the Shuttle Radar Topography Mission (SRTM) project. This was also the last solo flight of Endeavour; all future flights for Endeavour became devoted to the International Space ...
Taken from Space Shuttle, 15 April 1994. The Spaceborne Imaging Radar (SIR) – full name 'Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR)', [1] is a synthetic aperture radar which flew on two separate shuttle missions. Once from the Space Shuttle Endeavour in April 1994 on and again in October 1994 on .
The Space Imaging Radar system (SIR-C) was the only part of the payload to be reactivated. The data recorded during the STS-59 mission would fill the equivalent of 20,000 encyclopedia volumes. Payload managers reported that more than 70 million square kilometers of the Earth's surface, including land and sea, have been mapped on this flight.
The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.
The OMS tests also helped adjust the Shuttle's orbit for use of the radar. [3] During the mission, President Reagan called the crew of STS-2 from Mission Control Center in Houston. [4] In the early planning stages of the Space Shuttle program, STS-2 was intended to be a reboost mission for the aging Skylab space station.
ORS-2. Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit.A number of Earth-observing satellites, such as RADARSAT, have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth.
TriDAR was again carried on board Space Shuttle Discovery during the STS-131 mission to the International Space Station. The TriDAR operated during shuttle rendezvous with the ISS, and acquired useful data up till the shuttle R-bar Pitch Maneuver. At that point, a cabling issue resulted in a loss of communications. [4]
