NASA’s Chandra X-ray Observatory, which went into careful safe approach 10 October afterwards a annihilate with one of its stabilising gyroscopes, will resume accustomed science observations anon afterwards engineers complete software updates.
“The operations aggregation has auspiciously alternate the aircraft to its accustomed pointing mode,” NASA said in a statement. “The safe approach was acquired by a annihilate in one of Chandra’s gyroscopes consistent in a 3-second aeon of bad abstracts that in about-face led the on-board computer to account an incorrect amount for the aircraft momentum. The erroneous drive adumbration again triggered the safe mode.”
Engineers uplinked commands to put the doubtable gyro into assets and replaced it with a advantageous unit.
“Once configured with a alternation of pre-tested flight software patches, the aggregation will acknowledgment Chandra to science operations which are accepted to arise by the end of this week,” NASA said.
The Hubble Space Telescope, meanwhile, charcoal out of activity while engineers troubleshoot problems with one of its gyroscopes.
Hubble was launched with six gyros but alone needs three to accomplish normally. Two gyros bootless beforehand and a third suffered a baleful malfunction beforehand this month. The telescope’s abandoned actual advancement gyro was activated, but it, too, ran into problems.
Engineers are belief whether that gyro can be adequate to accustomed operation. If not, mission managers will apparatus a alleged single-gyro plan, operating Hubble in near-normal appearance with aloof one operational gyroscope while captivation the telescope’s added advantageous gyro in reserve.
