The Hubble telescope usually works after a failed gyro event



After his remaining backup gyroscopes failed, the Hubble Space Telescope went into safe mode, while ground control scientists figured out what to do next. NASA recently reported that the space observatory is back to normal. ( NASA )

The Hubble Space Telescope returned to normal operation two weeks after the malfunction of one of the gyroscopes aboard the spacecraft.

NASA reported on Saturday, October 27, that nearly the 30-year-old observatory was taken out of safe mode. It has also completed its first scientific observation since the malfunction, collecting data on a distant star-forming galaxy DSF2237B-1

-IR over the weekend.

What happened to the Hubble Space Telescope?

The Hubble Space Question The telescope started on October 6, when one of the three gyroscopes used failed. However, there were no concerns as the spacecraft is equipped with six gyros, three of which are designed for such situations.

Unfortunately, two other gyros have failed in the past and left one last gyro in memory. When this last backup gyro failed, NASA had to put the Hubble Space Telescope in a safe mode.

A gyroscope is important for the operations of the space observatory. The instrument is responsible for stabilizing and aligning the telescope in a particular direction for long observation periods.

The backup gyro returned inaccurate speeds during operation. In the last two weeks. Soil control scientists conducted basic troubleshooting techniques, including turning the instrument off and on to correct the problem. Fortunately, the gyroscope produced normal speeds last week, which makes NASA believe that the space observatory is ready to return to normal operation.

The US Space Agency said the Hubble is currently operating at three gyros and is expected to be up and running for the next decade or more. The telescope has experienced similar problems in the past, but in 2009 Space-Walking Shuttle astronauts installed six new gyros in the Observatory.

Chandra Also Back to Normal

The Chandra X-ray Observatory, which also entered safe mode A few days after Hubble, has also returned to normal operations. On October 21, NASA officials said that the glitch had been fixed and the space observatory had returned to work.

The space agency also identified a problem in the orientation and orientation of the spacecraft. His gyroscope did not work as expected.

To solve the problem, the ground control scientists enabled a new configuration for the spacecraft gyroscope. NASA will continue to monitor and fine-tune the performance of the gyroscope configuration as needed.
