Hitomi was a facility-class mission launched on a JAXA H-IIA into low Earth orbit on Feb 17, 2016 from Tanegashima Space Center in Japan. Hitomi was the Japan's sixth X-ray astronomy mission, and was primarily developed at the Institute of Space and Astronautical Science of Japan Aerospace Exploration Agency (ISAS/JAXA) in collaboration with U.S. (NASA/GSFC) and Japanese institutions with contributions from the European Space Agency (ESA), the Netherlands Institute for Space Research (SRON), the Canadian Space Agency (CSA) and US and European institutions. On March 27, 2016, JAXA lost contact with the satellite and on April 28 announced to cease the efforts to restore the mission operations. Hitomi collected about one month worth of data with its instruments.
