The Spectrum Astro SA-200 satellite bus provided a flexible platform for satellites launched by the Pegasus booster.he Spectrum Astro SA-200 satellite bus provided a flexible platform for satellites launched by the Pegasus booster.

AKA: Fermi;GeoEye;Leostar;NFIRE;Nustar;SA;STSS. Status: Operational 2000. First Launch: 2000-07-19. Last Launch: 2013-02-11. Number: 7 . Gross mass: 500 kg (1,100 lb).

Spectrum Astro was acquired by General Dynamics C4 Division in 2006. Spectrum Astro's SA-200 family of satellites were marketed in three variants:

  • The SA-200B provided an affordable platform for data collecting space missions at LEO, MEO, HEO, and GEO orbits. The spacecraft combining proven high-capability space components with an open architecture designed for concurrent development and early interface and functional test.
  • The SA-200HP was a scalable platform for missions ranging from remote-sensing operations requiring continuous "push broom" sensors in any low-earth orbit, to planetary missions demanding precision pointing and extended lifetimes. This platform provided a range of electric power and propulsion capabilities with provisions for complete redundancy, depending on mission need and cost constraints. The SA-200HP was sized to support payloads launched by Pegasus, Taurus, or Athena launch vehicles.
  • The SA-200S was designed for missions with solar inertial, sun synchronous near-6am orbits, or missions that required duty-cycled, high-accuracy point tracking. It could be configured for a Pegasus, Athena, Delta, or Taurus launch. The bus provided a full capability monopropellant hydrazine RCS for orbit acquisition and precision control, and offered substantial pointing control and agility. Options for non-sun-synchronous orbits allowed payload operations for any sun orientation.

    Mightysat 2.1, also known as Sindri, used a Spectrum Astro SA-200B satellite bus. The spacecraft carried a hyperspectral imager for earth imaging and spectroscopy, as well as satellite technology experiments such as advanced solar arrays. An Aerospace Corp./DARPA picosatellite experiment, consisting of two small boxes connected by a deployable tether, was deployed later.

    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. Air dropped in Mayport DZ.

Secondary payloads included Tesat, a German laser communications terminal, and its hydrazine propulsion system. This was used to maneuver the satellite from its initial 255 km x 465 km x 48.2 deg orbit to 489 km x 497 km by 18 May. The orbit was changed to 243 km x 487 km on 9 August and by 23 August was 219 km x 450 km. The satellite had a dry mass of 380 kg dry, was 2.7 m long and 1.3 m in diameter.
