The ASTRO-H Mission

ASTRO-H Overview

The ASTRO-H is the sixth X-ray observation satellite that will explore the extreme universe that is abundant with high energy phenomena around black holes and supernova explosions, and observe a cluster of galaxies filled with high-temperature plasma.

Objectives The purpose of ASTRO-H is to explore the structure and evolution of Universe with the following observational capabilities:
  1. One of the first imaging and spectroscopic observations with the hard X-ray telescope.
  2. The first spectroscopic observations with an extremely high energy resolution of the micro-calorimeter.
  3. The most sensitive wideband observation over an energy range from 0.3 to 600 keV.
