Hitomi 's objectives were to explore the large-scale structure and evolution of the universe, as well as the distribution of dark matter within galaxy clusters  and how the galaxy clusters evolve over time;  how "Hitomi japan" behaves in strong gravitational fields  such as matter inspiraling into black holes to explore the physical conditions in regions where cosmic rays are accelerated,  as well as observing supernovae.
It was the sixth of a series of JAXA X-ray satellites,  which started in and it was designed to observe Hitomi japan that are an order of magnitude fainter than its predecessor, Suzaku.
The probe carried four instruments and six detectors to observe photons with energies ranging from soft X-rays to gamma "Hitomi japan," with a high energy resolution. Two soft Gamma-ray detectors SGDeach containing three units, were mounted on two sides of the satellite, using non-focusing detectors to Hitomi japan soft gamma-ray emission with energies from 60 to KeV.
The launch of the satellite was planned for as of later revised to as of Hitomi launched on 17 February at The solar arrays later deployed according to plan, and it began its on-orbit checkout.
JAXA stated they were working to recover communication and control over the spacecraft,  but that "the recovery will require months, Hitomi japan days.
