A Japanese satellite that was thought to have failed shortly after launch has shown unexpected signs of activity, sending beacon signals back to the Japan Aerospace Exploration Agency. The Hitomi satellite launched on February 17 but was unable to make contact until a brief signal burst on March 28, and footage filmed from the ground appears to show the satellite tumbling through space. This contact suggests that there is hope of recovering Hitomi, although it appears that the satellite has suffered a loss of directional control.
