The ASTRO-E mission is an international cooperative project between NASA and the Japanese Institute of Space and Astronautical Science (ISAS). The spacecraft, launch vehicle, and some of the science instrumentation are being provided by ISAS. In this joint project, GSFC will provide the X-Ray Spectrometer (XRS) Detector System (XDS) and five(5) X-Ray Telescopes (XRT). Additionally, GSFC will manage a reimbursable contract with MIT to provide the Charge Couple Device (CCD), the Focal Plane Assembly (FPA), and its associated Analog Electronics Assembly (AE) for the X-Ray Imaging Spectrometer (XIS) instrument. ASTRO-E Mission is the Japan's fifth X-Ray Astronomy mission scheduled to be launched on January 24, 2000. The major purposes of ASTRO-E is to observe astronomical objects in a cosmological distance in X-Ray wavelengths, to perform very fine and wide-band X-Ray spectroscopy of cosmic high temperature plasmas. ASTRO-E also carries the Japanese Hard X-Ray Detector (HXD). The XIS utilizes four X-Ray CCD cameras in conjunction with four of the x-ray telescopes to cover an energy range of 0.4-10 keV with a typical energy resolution of 100 eV. The XDS is an array of X-Ray micro calorimeters which uses the fifth x-ray telescope and covers an energy range similar to XIS with a typical energy resolution of 12 eV. The HXD is a combination of well type phoswitch scintilators and Si Pin detectors and covers a 10-700 keV energy range.
