The space observatory is scheduled to take off at 3:45 a.m. EST from the Tanegashima Space Center in Kagoshima, Japan. The launch date was originally scheduled for February 12, but was delayed due to bad weather.


The 2,700-kilogram (6,000 lb) satellite is equipped with four telescopes and six detectors, allowing it to study both “hard” and “soft” x-rays and gamma rays.


ASTRO-H is capable of observing X-ray sources, like galaxy clusters and neutron stars, more than 10 times fainter than its predecessor, Suzaku, which operated from 2005 to 2015.


Japan's X-ray satellite is expected to provide breakthroughs in a wide variety of high-energy phenomena in the cosmos, ranging from the superheated material on the brink of falling into a black hole to the evolution of vast galaxy clusters.


ASTRO-H is expected to operate in low Earth orbit for three years.
