Te­le­scope off­line

Sunday Star-Times - - WORLD -

An­other Nasa space te­le­scope has shut down, halt­ing sci­ence ob­ser­va­tions. Less than a week af­ter the Hub­ble Space Te­le­scope went off­line, the Chan­dra X-ray Ob­ser­va­tory has done the same thing. Nasa said Chan­dra au­to­mat­i­cally went into so-called safe mode this week, pos­si­bly be­cause of a gy­ro­scope prob­lem. Hub­ble went into hi­ber­na­tion last week­end due to a gy­ro­scope fail­ure. Flight con­trollers are work­ing to re­sume oper­a­tions with both tele­scopes. A Nasa as­tronomer tweeted: ‘‘Chan­dra de­cided that if Hub­ble could have a lit­tle va­ca­tion, it wanted one, too.’’
