|High Energy Astrophysics |
(X-ray and Gamma-ray Astronomy)
The Constellation-X Observatory is a combination of several X-ray satellites orbiting in close proximity to each other and working in unison to generate the observing power of one giant telescope.
|EXIST - Energetic X-ray Imaging Survey Telescope|
Is a proposed hard X-ray imaging all-sky deep survey mission and was recommended by the 2001 Report of the Decadal Survey. It is a strong candidate to be the Black Hole Finder Probe, one of the three "Einstein Probes" in the Beyond Einstein Program described in the current Roadmap for NASA Space Science missions.
|GRIP - Gamma Ray Imaging Payload|
The Gamma Ray Imaging Payload (GRIP2) is a balloon borne coded-aperture telescope designed for imaging observations of galactic and extragalactic gamma-ray sources. GRIP2 incoorporates a rotating hexagonal coded aperture mask and a 70 cm diameter NaI(Ti)/CsI(Na) phoswich detector.
|HEFT - High Energy Focusing Telescope|
HEFT is an balloon-borne experiment that will use depth-graded multilayer optics and Cadmium Zinc Telluride pixel detectors to image astrophysical sources in the hard X-ray (20 - 100 keV) band.
|NUSTAR - Nuclear Spectroscopic Telescope Array|
NuSTAR will carry the first focusing hard X-ray (6-80 keV) telescope. It will eliminate high detector backgrounds, allow true imaging, and permit the use of compact high performance detectors.
|XTE - X-ray Timing Explorer|
The Rossi X-ray Timing Explorer (RXTE) was launched on December 30, 1995 from NASA's Kennedy Space Center. The mission is managed and controlled by NASA's Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. RXTE features unprecedented time resolution in combination with moderate spectral resolution to explore the variability of X-ray sources.
