Associated space launch
Astro-H is the 6th satellite in a series of X-ray telescopes by JAXA and ISAS. Its 4 instruments on board will cover the X-ray and Gamma ray regions. This region consists of photons with energy ranging from 0.3-600keV, and the telescope will provide the highest resolution ever achieved of 3-10 keV bands. The craft weighs 2.7 tonnes and will be placed into a circular orbit 575km above the ground, with an inclination of 31 degrees.
H-2A R/B was lifted into orbit during the mission ‘H-IIA 202 | Astro-H (Hitomi)’, on board a H-IIA space rocket.
The launch took place on Feb. 17, 2016, 8:45 a.m. from Yoshinobu Launch Complex LP-1.
