The search for B produced 2 results out of 249 records BBXRT Launch Date: 12/02/1990 The Broad Band X-ray Telescope (BBXRT) marked the first opportunity for performing X-ray observations over a broad energy range with a moderate energy resolution. This energy resolution coupled with an extremely low detector background made BBXRT a very powerful tool for the study of continuum and line emission from cosmic sources, and the scientific results form a great start of what can be expected from Astro-D. The observing program was designed to be an even mix of Galactic and extragalactic targets. BBXRT was designed and built at the Laboratory for High Energy Astrophysics (LHEA) at NASA/GSFC. Other Name(s):  Broad-Band X-Ray Telescope |  GSFC Link  |  NSSDC Link  |  Image Gallery  |   Beacon Explorer A Launch Date: 03/19/1964 The Beacon Explorer-A was a small ionospheric research satellite instrumented with an electrostatic probe, ionospheric radio beacon, a passive laser tracking reflector, and a navigation experiment. Its primary purpose was to study electron densities in a near-Earth space. Other Name(s):  BE-A, S 66 |  NSSDC Link  |  Additional URL 1  |
