Hubble Space Telescope Apparently in & # 039; Safe Mode & # 039; After Gyroscope Failure







Iconic of NASA Hubble Space Telescope It is out of action for the moment.



	

	Hubble, which has been watching the skies since 1990, entered a safe mode of protection after another of its orientation maintenance gyros failed, mission team members said Sunday night (October 7). .

		"It's true, very stressful weekend, at this moment, the HST is in safe mode while we figure out what to do." Another turn of the turn has failed, the first step is to try to return the last turn, which had been turned off, and being problematic, "Rachel Osten, deputy head of mission for Hubble at the Space Telescope Science Institute in Baltimore, said through Twitter on Sunday, in response to questions and comments tweeted about the rumored gyroscope failure.

				It is true. Very stressful weekend. At this time, the HST is in safe mode while we figure out what to do. Another turn did not work. The first step is to try to recover the last turn, which had been turned off, and is being problematic.

		Hubble has six gyros, all of which were replaced by astronauts walking in space during a service mission in May 2009. The telescope needs three gyros that work to "ensure optimal efficiency" the team members of the mission have written, and the error reduces that number to two (if the "problematic" that had been turned off can not go back online).

		But that does not mean it's time to panic. Hubble can do good science with two gyros, or even one, astrophysicist Grant Tremblay of the Harvard-Smithsonian Center for Astrophysics said on Twitter on Sunday.

		"* YES * the third one does not turn again, I would not be surprised if it changed to 1 turn mode, keeping the second one as a reserve, maybe @rachelosten knows it, but I think it's a stressful and difficult decision. bright in @STScI can recover the third. Stress ". he tweeted.

		"It's not a difficult decision, @astrogrant: the plan has always been to switch to 1-gyro mode when there are two left, there is not much difference between 2 and 1, and a lot of extra observation time is bought. desperately " Osten tweeted in response.

		"It's not really scary, we knew it was coming in. The gyroscope lasted about six months longer than we thought (it almost disconnected it in the spring.) We'll solve the problems and we'll come back," Osten added. in another tweet.



				It's not really scary, we knew it was coming. The gyro lasted about six months longer than we thought (it almost disconnected in the spring). We will work through the problems and we will return.

		Neither NASA nor its partner in the mission, the European Space Agency, had made an official statement on the subject of the gyroscope until Sunday night. 

		Hubble is not the only famous NASA robot that is experiencing some technical difficulties at this time. From the agency Opportunity Mars Rover has not taken a look since June 10, when a massive dust storm blocked so much sunlight that the solar-powered rover could not recharge its batteries. That storm has declined since then, and Opportunity team members recently increased attempts to stop the six-wheeled robot, which has been exploring the red planet since January 2004.

		Opportunity's youngest and largest cousin, Curiosity, recently switched to his backup computer after experiencing memory problems with his master brain. And the Kepler space telescope, which has discovered about 70 percent of the 3,800 exoplanets confirmed to date, has as little fuel as its handlers. recently turn it off, to make sure you have enough fuel left to face Earth and transmit your latest data to Earth next week.

		NASA's Dawn spacecraft, which has been surrounding the dwarf planet Ceres since March 2015, is also running out of fuel. Their innovative mission could end as early as this month, said Dawn's team members.
