The Pegasus Project was a NASA initiative to study the frequency of micrometeoroid impacts on spacecraft by means of a constellation of three satellites launched in 1965. [ 1 ] [ 2 ] All three Pegasus satellites were launched by Saturn I rockets , and remained connected with their upper stages.
As of 2015, the most recent Pegasus XL to be purchased — a planned June 2017 launch of NASA's Ionospheric Connection Explorer (ICON) mission — had a total cost of US$56.3 million, which NASA notes includes "firm-fixed launch service costs, spacecraft processing, payload integration, tracking, data and telemetry and other launch support ...
During the mission, an uncrewed Orion capsule spent 10 days in a distant retrograde 60,000 kilometers (37,000 mi) orbit around the Moon before returning to Earth. [10] Artemis II, the first crewed mission of the program, will launch four astronauts in 2025 [11] on a free-return flyby of the Moon at a distance of 8,900 kilometers (5,500 mi). [12 ...
The first Pegasus launch to use Stargazer was conducted on June 27, 1994, as the maiden flight of the Pegasus-XL. Previous launches used the NASA-operated Boeing B-52 nicknamed "Balls 8," which was also used for four subsequent launches, as the original Pegasus could not be launched from Stargazer due to clearance issues. A modified version ...
The radar set failed a CADFISS test, where all the stations in the network had to transmit information to NASA to ensure accurate information could be obtained. The failed part was replaced within 3 hours, but when the Capsule communicator asked for a realistic estimate, he was told 24 hours. The mission was immediately scrubbed for one day.
The ultimate goal of NASA's Constellation program was a crewed mission landing humans on Mars in the 2030s as a spiritual successor to the Apollo Applications Program in the 1960s. The mission would utilize the hardware of the Constellation Project, primarily the Orion spacecraft (or a variation based on the Orion), and the Ares V cargo-launch ...
Wide-field Infrared Explorer (WIRE, also Explorer 75 and SMEX-5) was a NASA satellite launched on 5 March 1999, on the Pegasus XL launch vehicle into polar orbit between 409 and 426 km (254 and 265 mi) above the surface of Earth.
Pegasus 3 was a Pegasus spacecraft, consisting of 1,450 kilograms (3,200 lb) of instruments, attached to the S-IV upper stage of the carrier rocket which had placed it into orbit. [1] It had a total mass of 10,323 kilograms (22,758 lb), [ 2 ] and was equipped with two sets of micrometeoroid detection panels, and a radio for tracking and ...
