description Hitomi (ASTRO-H) Overview
Hitomi (ASTRO-H) was a Japanese X-ray astronomy satellite developed by JAXA with NASA cooperation, launched on 17 February 2016 from the Tanegashima space centre. Carrying instruments for imaging and high-resolution X-ray spectroscopy, it was designed to study black holes, galaxy clusters, and supernova remnants, succeeding the Suzaku mission. About five weeks after launch, a cascading attitude-control failure caused the spacecraft to spin up and break apart; contact was lost in late March 2016 and the mission was declared lost soon afterward.
