The NASA / ESA Hubble Space Telescope (HST) has entered safe mode of protection after the failure of another of the gyros that maintains its orientation.
"It's true, very stressful weekend, at this moment, the HST is in safe mode while we figure out what to do Another gyroscope has failed The first step is to try to recover the last gyroscope, which was off and is being problematic", said Rachel Osten, deputy head of mission at the Space Telescope Science Institute in Baltimore, through her Twitter account on October 7, in response to questions and comments on Twitter about the rumored gyroscope failure.
Hubble has six gyros, all of which were replaced by astronauts during a service mission in May 2009. The telescope needs three gyros that work to "guarantee optimal efficiency", according to Space.com that cites the mission website, and the present ruling has reduced that number to two.
All in all, the Hubble telescope can continue to operate with two gyroscopes, or even one, says astrophysicist Grant Tremblay, of the Harvard-Smithsonian Center for Astrophysics, on his Twitter account.
