On February 17 at 5:45pm JST this H-IIA rocket blasted skyward from JAXA’s Tanegashima Space Center located off the southern coast of Japan, planet Earth. Onboard was the ASTRO-H X-ray astronomy satellite, now in orbit. Designed to explore the extreme cosmos from black holes to massive galaxy clusters, the satellite observatory is equipped with four cutting-edge X-ray telescopes and instruments sensitive to photon energies from 300 to 600,000 electron volts. By comparison, visible light photon energies are 2 to 3 electron volts. Following a tradition of renaming satellites after their successful launch, ASTRO-H has been newly dubbed “Hitomi”, inspired by an ancient legend of dragons. Hitomi means “the pupil of the eye”.

在2月17日晚上5:45 (JST)，這枚H-IIA火箭從位於日本南部沿海的JAXA種子島太空中心發射升空。搭載在火箭上的ASTRO-H X射線天文衛星現在已經進入軌道。該衛星觀測站旨在探索極端的宇宙現象，從黑洞到巨大星系團，配備了四台尖端的X射線望遠鏡及對300至600,000電子伏特光子能量敏感的儀器。相比之下，可見光光子的能量只有2至3電子伏特。根據衛星成功發射的傳統，ASTRO-H在新命名後被稱為”Hitomi”，靈感來自於古老的龍的傳說。”Hitomi”的意思是”眼睛的瞳孔”。
