The ASTRO-H X-ray Observatory
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). ASTRO-H will investigate the physics of the high-energy
universe via a suite of four instruments, covering a very wide energy range,
from 0.3 keV to 600 keV. These instruments include a high-resolution,
high-throughput spectrometer sensitive over 0.3-2 keV with high spectral
resolution of Delta E < 7 eV, enabled by a micro-calorimeter array located in
the focal plane of thin-foil X-ray optics; hard X-ray imaging spectrometers
covering 5-80 keV, located in the focal plane of multilayer-coated, focusing
hard X-ray mirrors; a wide-field imaging spectrometer sensitive over 0.4-12
keV, with an X-ray CCD camera in the focal plane of a soft X-ray telescope; and
a non-focusing Compton-camera type soft gamma-ray detector, sensitive in the
40-600 keV band. The simultaneous broad bandpass, coupled with high spectral
resolution, will enable the pursuit of a wide variety of important science
themes.Comment: 22 pages, 17 figures, Proceedings of the SPIE Astronomical

Hitomi (ASTRO-H) X-ray Astronomy Satellite
The Hitomi (ASTRO-H) mission is the sixth Japanese x-ray astronomy satellite developed by a large international collaboration, including Japan, USA, Canada, and Europe. The mission aimed to provide the highest energy resolution ever achieved at E > 2 keV, using a microcalorimeter instrument, and to cover a wide energy range spanning four decades in energy from soft x-rays to gamma rays. After a successful launch on February 17, 2016, the spacecraft lost its function on March 26, 2016, but the commissioning phase for about a month provided valuable information on the onboard instruments and the spacecraft system, including astrophysical results obtained from first light observations. The paper describes the Hitomi (ASTRO-H) mission, its capabilities, the initial operation, and the instruments/spacecraft performances confirmed during the commissioning operations for about a month

The ASTRO-H X-ray astronomy satellite
The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly
successful X-ray missions developed by the Institute of Space and Astronautical
Science (ISAS), with a planned launch in 2015. The ASTRO-H mission is equipped
with a suite of sensitive instruments with the highest energy resolution ever
achieved at E > 3 keV and a wide energy range spanning four decades in energy
from soft X-rays to gamma-rays. The simultaneous broad band pass, coupled with
the high spectral resolution of Delta E < 7 eV of the micro-calorimeter, will
enable a wide variety of important science themes to be pursued. ASTRO-H is
expected to provide breakthrough results in scientific areas as diverse as the
large-scale structure of the Universe and its evolution, the behavior of matter
in the gravitational strong field regime, the physical conditions in sites of
cosmic-ray acceleration, and the distribution of dark matter in galaxy clusters
at different redshifts.Comment: 24 pages, 18 figures, Proceedings of the SPIE Astronomical
