JAXA, NASA approve replacement for failed Hitomi astronomy satellite
Artist’s concept of the failed Hitomi satellite. Credit: JAXA The Japanese space agency is moving ahead with a smaller-scale X-ray astronomy satellite to replace the failed Hitomi observatory, which spun out of control about a month-and-a-half after its launch last year. The X-ray Astronomy Recovery Mission, or XARM, could launch as soon as March 2021,…

Japan’s Hitomi observatory made cosmic discovery before failing
The Perseus galaxy cluster is filled with hot X-ray-emitting gas, as seen in this image from NASA’s Chandra X-ray Observatory. Astronomers using the Soft X-ray Spectrometer aboard the Hitomi satellite have, for the first time, mapped the motion of this gas and determined its velocity structure across a large part of the cluster. The square…

Japan gives up on rescuing black hole observatory
Artist’s concept of Japan’s Hitomi satellite. Credit: JAXA/Akihiro Ikeshita Japan’s space agency says it has ceased efforts to rescue a failed X-ray astronomy satellite after it spun out of control and broke apart in orbit, declaring the nearly $400 million mission lost two months after its launch. Controllers on the ground lost contact with the…

Attitude control failures led to break-up of Japanese astronomy satellite
Artist’s concept of Japan’s Hitomi satellite. Credit: JAXA/Akihiro Ikeshita Japan’s Hitomi X-ray observatory was beset by a series of attitude control problems March 26 that caused the satellite to spin out of control and shed sizable chunks of its power-generating solar panels or deployable telescope, according to engineers analyzing fragments of telemetry data sent to…

U.S. military rules out collision as cause of Hitomi satellite’s woes
The Hitomi satellite is seen Nov. 27 at a press day held before its launch. Credit: JAXA As Japanese ground controllers struggle to restore communications with a tumbling space telescope in orbit, the U.S. military’s space surveillance experts have eliminated one cause for the satellite’s troubles. A military spokesperson told Spaceflight Now in an email…

Japan’s newest space telescope goes silent
Updated on March 28. Artist’s concept of the Hitomi observatory. Credit: JAXA/Akihiro Ikeshita Japan has lost contact with the newly-launched Hitomi space telescope, and ground observations indicate the satellite has shed debris and may be tumbling in orbit more than 350 miles above Earth. Ground controllers lost contact with the Hitomi black hole observatory at the…

Photos: H-2A rocket soars on groundbreaking astronomy mission
Burning a mixture of super-cold liquid hydrogen, liquid oxygen and pre-packed solid propellant, Japan’s H-2A rocket vaulted into a deep blue evening sky over the beaches of Tanegashima Island on Wednesday with a satellite that will see the surroundings of black holes better than ever before. The 174-foot-tall (53-meter) rocket blasted off at 0845 GMT…
