Abstract
A review of the Astro-H mission is presented here on behalf of the Astro-H collaboration. The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). One of the main uniquenesses of the ASTRO-H satellite is the high sensitivity and imaging capability of the wide energy band from 0.3 keV to 600 keV. The coverage is achieved by combining the four instruments of the SXS, SXI, HXI, and SGD. The other main uniqueness is a spectroscopic capability not only for a point-like source but also for an extended source with high spectral resolution of Δ<em>E</em>~4÷7eV of SXS. Using the unique powers of these instruments, ASTRO-H will address unresolved issues in high-energy astrophysics.
Highlights
Introduction and current statusASTRO-H is a facilityclass mission to be launched on JAXA H-IIA into low Earth orbit in 2014 [1,2,3]
ASTRO-H is a pointing observation-type satellite; each target is pointed until the integrated observing time is accumulated, and slews to the target
ASTRO-H has just completed the first half of the critical design review (CDR-1) which is required before making the system tests using the Thermal Test Model (TTM) or The Mechanical Test Model (MTM) and producing a part of the flight modules
Summary
ASTRO-H (formerly known as “”) is a facilityclass mission to be launched on JAXA H-IIA into low Earth orbit in 2014 [1,2,3]. ASTRO-H will be launched into a circular orbit with altitude 500 ÷ 600 km, and inclination 31 degrees or less. ASTRO-H has just completed the first half of the critical design review (CDR-1) which is required before making the system tests using the Thermal Test Model (TTM) or The Mechanical Test Model (MTM) and producing a part of the flight modules. We will summarize the mission concept and the current baseline configuration of instruments of ASTRO-H. A comprehensive introduction and most recent reviews of the ASTRO-H mission will be presented at the SPIE meeting in July, 2012 [3]
