The High Energy Transient Experiment (HETE) was an international mission led by The Massachusetts Institute of Technology (MIT). Its prime objective was to carry out the first multiwavelength study of gamma ray bursts (GRBs) with UV, X-ray, and gamma ray instruments. A unique feature of the mission was its capability to localise bursts with several arcsecond accuracy, in near real-time aboard the spacecraft. These positions were to be transmitted to the ground, and picked up by a global network of primary and secondary ground stations (SGS), enabling sensitive follow-up studies. However the satellite was never released from its payload fitting. Although signals were received, the solar panels could not deploy, and it went silent after a few days when its batteries ran down.

SWAS, the Sub-millimetre Wave Astronomy Satellite, had a 0.6m telescope with a 490 to 550 GHz sub-millimetre receiver and an acousto-optical spectrometer. SWAS was used to study the cooling of molecular cloud cores, the sites of star formation in our galaxy, by measuring lines from molecular oxygen and water.

  • WIRE - . Nation: USA. Agency: NASA Greenbelt. Class: Astronomy. Type: X-ray astronomy satellite. Spacecraft: WIRE. Decay Date: 2011-05-10 . USAF Sat Cat: 25646 . COSPAR: 1999-011A. Apogee: 582 km (361 mi). Perigee: 537 km (333 mi). Inclination: 97.5000 deg. NASA's long-delayed WIRE (Wide Field Infrared Explorer) astronomy satellite was the fifth Small Explorer (SMEX) mission managed by NASA-Goddard. The L-1011 Stargazer launch aircraft took off from Vandenberg's runway 30/12 at 01:55 GMT on March 2 for the first launch attempt. The planned 02:56 GMT launch was cancelled at T-46 seconds due to a problem with the tail fin release mechanism of the Pegasus XL launch vehicle. The second attempt was successful, with the Pegaus XL being dropped at 36 degrees N x 123 degrees W over the Pacific Ocean at 02:56 GMT. However the WIRE ran into serious trouble shortly after orbit injection. The cover of the solid hydrogen telescope ejected prematurely, and the cryogenic coolant evaporated and vented, spinning the satellite out of control. WIRE was going to make an infrared photometry survey, generating a large catalog of galaxies and quasars.

  • TERRIERS - . Nation: USA. Agency: NASA Greenbelt. Manufacturer: AeroAstro. Class: Technology. Type: Military technology satellite. Spacecraft: TERRIERS. USAF Sat Cat: 25735 . COSPAR: 1999-026A. Apogee: 493 km (306 mi). Perigee: 484 km (300 mi). Inclination: 97.1000 deg. Period: 94.40 min. TERRIERS was part of NASA's Student Explorer Demonstration Initiative (STEDI), which was a precursor program to the UNEX (University Explorer) series. STEDI was managed by USRA (the Universities Space Research Association) for NASA, while UNEX was to be more directly managed by NASA-GSFC. TERRIERS was to be operated by the space physics group at Boston University for ionosphere studies, and carried TESS, a set of extreme ultraviolet (EUV) spectrographs to get electron density and thermosphere emission profiles. The GISSMO instrument measured the solar EUV flux. The spacecraft was built by AeroAstro and based on HETE. TERRIERS was placed in the correct orbit, but it failed to orient its solar panel to the Sun and ran out of battery power by May 20. Controllers were optimistic that when its orbit processes to a better sun angle the satellite could be revived. Additional Details: here....
  • MUBLCOM - . Nation: USA. Agency: USA. Manufacturer: Germantown. Class: Communications. Type: Military communications satellite. Spacecraft: Microstar. USAF Sat Cat: 25736 . COSPAR: 1999-026B. Apogee: 745 km (462 mi). Perigee: 738 km (458 mi). Inclination: 97.7000 deg. Period: 99.70 min. After deploying the TERRIERS satellite, the conical Payload Adapter Fitting (1998-26E) was jettisoned at 05:21 GMT, leaving the disk-shaped MUBLCOM satellite attached to the Pegasus XL PRIMEX HAPS-Lite stage. The second HAPS burn at 05:22 GMT raised apogee to 775 km, followed by a third, apogee burn at 06:10 GMT which circularised the orbit. MUBLCOM was deployed to a 769 km x 776 km x 97.7 degree orbit. The final HAPS burn then placed the depleted HAPS stage in a lower 388 km x 722 km x 97.1 degree disposal orbit. MUBLCOM (Multiple beam Beyond Line-of-sight Communications) was an experimental satellite funded by DARPA and managed by the US Army's Communications-Electronics Command (CECOM) at Ft Monmouth, New Jersey. It was built by Orbital Sciences using the Microstar (Orbcomm type) bus and carries a payload testing hand-held radio satellite communications for the armed forces.

    Six years later MUBLCOM was the target for the DART Autonomous Rendezvous Technology mission. On April 16, 2005, DART closed within 100 m of MUBLCOM satellite, then evidently began a series of out-of-control maneuvers resulting in an in-space collission and MUBLCOM being bumped into a 3 to 5 km higher orbit. DART was deorbited while MUBLCOM, still functioned, continued on in space.

HESSI, the sixth Small Explorer, carried a rotating modulation collimator transform telescope, imaging solar flares in the hard X-ray spectrum. The launch marked the return to flight of Pegasus after the Hyper-X failure. The launch was originally to have occurred on 28 March 2001. The L-1011 launch aircraft took off at 19:29 GMT from the Cape Canaveral Skid Strip RW30/12, and headed out to the drop area at 28.0 N 78.5 W over the Atlantic. Drop of the Pegasus in the Atlantic Drop Zone at 28.0 N 78.5 W was at 20:58 GMT, with ignition 5 seconds later. The Pegasus reached orbit at 21:07 GMT. On the first pass it was confirmed that the solar panels had opened.

    The satellite rotated at 15 rpm, imaging by reconstructing the Fourier components from the time modulation of the solar x-ray flux through a set of 9 grids each 9 cm in diameter. It was expected to make images with a resolution of 2 arcseconds at 40 keV energies and 36 arcseconds at 1 MeV energies. The launch delays meant that HESSI missed some of the best flares at solar max.

Perigee: 405 km (251 mi). Inclination: 13.0000 deg. Period: 97.30 min. The C/NOFS (Communication/Navigation Outage Forecasting System) satellite flew the US Defence Department's Space Test Program P00-3 space weather forecasting mission. The L-1011 launch aircraft staged from Kwajalein atoll to a release point for the Pegasus booster somewhere over the Pacific at 10.5229 N 167.7562 E. The research satellite carring ionospheric instruments, including Aerospace Corporation's CORISS receiver which used GPS signals to determine electron densities in the ionosphere, and the Naval Research Laboratory's CERTO ionospheric radio beacon. The spacecraft was built by General Dynamics C4 Systems (former Spectrum Astro) and was managed by DoD-STP and the Air Force Research Lab. The objective was to provide data that would allow better forecasts of ionospheric scintillation which causes problems with communications and GPS signals. The satellite deployed six 10-meter booms after release from the final booster stage.
