The Pegasus XL with fairing removed exposing payload bay and the IBEX satellite. The Pegasus XL, introduced in 1994 has lengthened stages to increase payload performance. [12] In the Pegasus XL, the first and second stages are lengthened into the Orion 50SXL and Orion 50XL, respectively. Higher stages are unchanged; flight operations are similar.
It was launched on 6 December 1998, at 00:57:54 UTC, from Vandenberg Air Force Base aboard a Pegasus XL launch vehicle. [1] The telescope was designed by the Smithsonian Astrophysical Observatory (SAO) and integrated by Ball Aerospace, while the spacecraft was built by NASA's Goddard Space Flight Center (GSFC). [2]
The IBEX satellite was carried into space on 19 October 2008, by the Pegasus XL launch vehicle. The launch vehicle was released from Stargazer, which took off from Kwajalein Atoll, at 17:47:23 UTC. [3] By launching from this site close to the equator, the Pegasus launch vehicle lifted as much as 16 kg (35 lb) more mass to orbit than it would ...
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 ...
On 25 April 2007, AIM was launched into a circular 550 km (340 mi) Sun-synchronous orbit by a Pegasus-XL launch vehicle, which was air-launched from the Lockheed L-1011 Stargazer aircraft operated by Orbital Sciences Corporation (OSC). [12]
Launch of CYGNSS on a Pegasus-XL. The CYGNSS mission was launched on December 15, 2016, at 13:37:21 UTC from a single Pegasus XL air-launched rocket. The rocket was deployed from a customized Lockheed L-1011 aircraft, Orbital ATK 's Stargazer, from a position 201 kilometers (125 mi) off the coast of Cape Canaveral, Florida.
