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.

Japan’s newest space telescope goes silent

28 March 2016 Stephen Clark

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.

Black hole observatory launched from Japan
