NASA says Hubble is back up after strange gyro problems

The Hubble Space Telescope – one of NASA's most reliable and important space assets – has had difficult weeks. Earlier this month, NASA revealed that Hubble was experiencing unexpected downtime after the failure of one of its gyroscopes and that the emergency gyroscope was producing strange results.

NASA engineers failed to explain why Hubble's gyroscope was bustling. They turned off and turned on the components, but that did not seem to solve the problem. Believing that a kind of blockage was responsible for the strange behavior of the telescope, the NASA team performed a series of maneuvers to release the gyroscope, correcting the problem. Now it seems that everything is working fine and NASA is comfortable announcing that Hubble is back to normal.

"On Friday night, the team began the process of restoring scientific instruments to the standard operating state," NASA said in a statement. "Hubble has completed the maneuvers to reach the first scientific observations and the telescope has collected its first scientific data since October 5."

The problem is still not entirely clear. The telescope was returning meaningless readings, and since gyroscopes are what the Hubble uses to orient itself when it drifts into orbit, it is vital that they work properly. The strategy of sending repeated telescopic maneuvers to the telescope seems to have solved the problem, so NASA moves forward and resumes scientific operations.

This is obviously good news, but NASA is quick to point out that Hubble is rising towards age. The telescope almost doubled the timing of its initial mission, which lasted more than 28 years, although it was designed for only about 15 years.

In a perfect world, the James Webb Space Telescope would already be operational and collect data alongside the Hubble. Unfortunately, due to a series of inexcusable gaffes by contractor Northrop Grumman, the planned launch of the telescope in 2007 was delayed by almost 15 years and cost nearly $ 10 billion. The initial budget for the new telescope was $ 500 million.
