NASA’s Chandra X-ray Observatory (CXO) is aback online afterwards a brusque assignment in safe approach aftermost week.
Just afore 10 a.m. EDT on Oct. 10, the telescope automatically entered a safe configuration, swapping analytical accouterments to back units and alteration administration for optimal solar console charging.
Officials were quick to point out that “all systems functioned as expected” in the brusque transition, and “the accurate instruments are safe.”
Launched in July 1999, Chandra is one of the alleged Great Observatories—along with the Hubble Amplitude Telescope, Compton Gamma Ray Observatory, and Spitzer Amplitude Telescope.
A set of high-tech mirrors accomplish Chandra acute to X-ray sources 100 times fainter than antecedent instruments of its kind.
Its antecedent five-year mission has continued back expired; CXO has been amphibian through amplitude for about 20 years—with no end in sight.
On Monday, NASA appear that a annihilate in one of Chandra’s gyroscopes created a domino aftereffect throughout the facility: A three-second aeon of bad abstracts led the on-board computer to account an incorrect amount for the aircraft momentum, which ultimately triggered safe mode.
“The aggregation has completed affairs to about-face gyroscopes and abode the gyroscope that accomplished the annihilate in reserve,” the bureau said in an update. “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.”
The catholic discharge came aloof canicule afterwards the Hubble Amplitude Telescope entered safe mode, afterward the abortion of one of its three alive gyroscopes.
It’s not all doom and anguish for NASA’s accumulating of interstellar spyglasses: Earlier this year, advisers acclimated Chandra’s able high-angular-resolution mirrors to abduction a ancestors account of stars in the array NGC 6231, some 5,000 ablaze years from Earth.
