After taking a short break of observation of the cosmos, NASA Space Hubble Telescope is officially backed up, and the observer has a stunning new look of galaxy that is staring at a distance.
On October 5, the Hubble telescope went into a "safe" safeguard when one of a gyroscope related to orientation failed. After about three weeks, the mission team was able to put the balky gyro and get Hubble back online. Shortly afterwards, the telescope settled in a field of galaxies that starred around 11 billion light years away from Earth, in the rich Pegasus.
The new image, taken on October 27 using Camera Field 3 of the telescope, was the first picture held by the telescope after returning to the service, according to NASA's statement. However, having Hubble online back was not easy enough; It included a whole team of engineers and experts who worked tirelessly to find a repair, officials said in the statement.

"This has been an incredible saga, built on the heroic efforts of the Hubble team," said Jennifer Wiseman, senior Hubble project scientist at NASA's Goddard Sailing Center in Greenbelt, Maryland, in the statement. "Thanks to this work, Space Hubble Telescope is back to be able to have full science that will benefit the astronomical community and the public for years to come."
Once members of the Hubble operations team were informed that the telescope had given the best to take a comment on science, they soon try to regenerate the failure, but unsuccessful.
Instead, the team was able to operate a backup on the spacecraft. However, the gyro quickly reported extremely high rotation rates of 450 degrees per hour, when Hubble actually dropped less than 1 degree per hour. The team had never seen high rates on any other drivers, according to the statement.
The Hubble telescope has a total of six drives, but it generally uses only three at a time to collect data about the telescope direction. Because two of the six telescope drivers have failed, then this is the final backup. That would mean that the operations team must specify how to get worked or could come to a "single-way" method, which would restrict comments Hubble is big.
In 2011, Hubble's control center focused on automated operations, meaning that people no longer monitor the 24-hour telescope. However, during the Hubble brief, members and teams continuously tracked the health and safety of the telescope.
"The team came together to staff around the clock, something we have not done in years," said Dave Haskins, Hubble's mission operations manager at Goddard in the statement. "For me, it was seamless. It shows the flexibility of the team."
NASA also came to an additional team of experts to identify how to correct uncommon behaviors. After weeks of creative thinking, persistent tests and minor difficulties, the team came to the conclusion that there could be some obstacle. They tried to solve this issue by changing the gap between different operational methods and rotating the spacecraft. As a result, the squirrel gradually changed its rotation to more normal rates, according to the statement.
Following that success, the team loaded a new software for the telescope and performed a series of practice movements to simulate real science observations. This ensured that the telescope was ready for action, with three working circles.
Meanwhile, other members of the team had turned their focus to prepare Hubble to use only one joke. Although those preparations are not needed at the moment, NASA officials said the telescope will inevitably be turned into a single-way approach at some point, and teams will now be ready for that.
"Many members of the team made personal sacrifices to work long shifts and shifts to ensure the health and safety of the observer, identifying a safe and effective way forward," said Pat Crouse, the Hubble project manager in the statement.
"Recovery is not only vital to the life expectancy of the observer, but Hubble is most productive in a three-way manner, and extending this historic period of productivity is the main objective of the mission," he said. "Hubble will continue to make incredible discoveries when it's time to operate in a single way, but because of the great effort and decision of the mission team, this is not the time now."
