SF Gate: Japan Aerospace Exploration Agency spokeswoman Izumi Yoshizaki said Monday that efforts to restore communication links since the problem began Saturday afternoon have been unsuccessful, and it was investigating what might have happened to the satellite, which is called Hitomi and was launched Feb. 17. via AP
'"We are really doing our best," she said by telephone in Tokyo.
'She said the agency was looking into a statement from the Joint Space Operations Center, or JSpOC, the U.S. military organization that tracks and identifies objects in space, that Hitomi may have splintered into several pieces.
'Whether that had happened or not is unclear, Yoshizaki said.
'Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, said he suspected the satellite had suffered an "energetic event," possibly a gas leak or a battery explosion, that sent it tumbling end-over-end. That would mean its antenna isn't pointing where it needs to, which is why the satellite can't communicate with the space agency, he said.'
