NASA is working to resume science operations of the Hubble Space Telescope after the spacecraft entered safe mode on Friday, October 5, shortly after 6:00 p.m. EDT. Unfortunately, that could take weeks to accomplish, which means the telescope will stay in safe mode until the team is able to troubleshoot the gyroscope.

In the wake of the fifth and final space shuttle servicing mission in 2009, two of the older-generation gyros failed, one at a time, leaving Hubble with just four operational units.

Responding to a claim that the safe mode was "scary news for the most famous telescope in history", Dr Osten downplayed the issues.

It's crucial that Hubble remain operational for at least the next few years, because its replacement, the James Webb Space Telescope, has been delayed until at least 2021.

"Mission experts are taking steps to return Hubble to great science", the National Aeronautics and Space Administration (NASA) said in a tweet. But only three gyros are needed for normal telescope operation with the others held in reserve. Thus, at this time, Hubble has two functional gyroscopes.

Hubble deputy mission head Rachel Osten, said, 'Very stressful weekend.

NASA said if they are unable to recover the malfunctioning gyro Hubble will resume science operations using just one device.

Named after astronomer Edwin P. Hubble, the foremost American astronomer of the 20th century, the sophisticated optical observatory was placed into orbit about 600 kilometers (370 miles) above Earth by the crew of the Space Shuttle Discovery on April 25, 1990.

"The gyro that failed had been exhibiting end-of-life behavior for approximately a year, and its failure was not unexpected; two other gyros of the same type had already failed".

Launched in 1990, Hubble has had trouble with its gyroscopes before. "We'll work through the issues and be back", she wrote.

We know that the unit has a total of six gyroscopes, because it was designed with multiple redundancy of all systems.

"It's not a hard decision, @astrogrant: the plan has always been to drop to 1-gyro mode when two remain". With only one gyro Hubble is restricted in what parts of the sky it can look, because it can only rotate in one direction at a time.

It is named after famed astronomer Edwin Hubble who was born in Missouri in 1889.

"So things closer in in the solar system than, say, the orbit of Mars, that would be more hard", he said.
