Back to Action! Highlight a new Nifty Image of Hubble Telescope Recall

NASA's Hubble Space Telescope is officially re-launched after a short observation of the cosmos, and this is a surprising new look at a remote and star-shaped galaxy.

On October 5, the Hubble telescope was "safely protected" when the guidance gyroscope failed. After three weeks, the mission team solved Gyro Balkya and returned to Hubble. Shortly afterwards, the telescope was placed in star-shaped galaxies, about 11 million light-years away around Earth, in the Pegasus constellation.

The new image, taken on October 27, was the first image taken by the telescope Wide Field Camera 3 after returning the service, according to a statement made by NASA. However, getting Hubble online was not easy; He worked with the entire team of engineers and experts to find a repair. [The Hubble Space Telescope’s Greatest Discoveries]

"This has been an incredible saga, according to the heroic efforts of the Hubble team," said Jennifer Wiseman, Hubble at the NASCAD's senior science scientist, Goddard Space Flight Center, in Greenbelt, Maryland. "This work will allow the Hubble Space Telescope to have full scientific capacity to benefit the astronomy community and the public in the coming years."

When Hubble's operating team members reported that telescopes had ceased watching science, they quickly tried to revive the gyro, but they did not succeed.

Instead, the group was able to activate gyro backup of the spacecraft. However, when gyro soon reported a high-speed 450-degree high rate, Hubble had less than 1 degree of power per day. The group had never seen rates in any other gyros, according to the statement.

The Hubble telescope has six gyros, but only three are used to collect telescope orientation data. Since the six gyroses of the two telescopes had not failed before, this was a last gyro copy. This means that the operating group would know how it works, or maybe it's a possible "environmentally friendly" way, which would limit Hubble's observations.

In 2011, Hubble's control center went through automated operations, 24 hours a day for people who did not control the telescope. However, during the unexpected connection of Hubble, team members constantly continued telescope health and safety.

"The groups joined the staff at the clock, something we did not have for years," said Dave Haskins, Hubble's Missions Operations Director in Goddard. "For me, it was perfect, it shows the group's versatility."

NASA also led a group of experts to find out how to handle the most common behavior of gyro. In weeks of creative thinking, constant testing and minor delays, the team concluded that there could be some types of locks. The gyro to solve this issue was transformed by different operating modes and attempted to rotate spacecraft spaceships. As a result, gyro has gradually changed its pace to normal rates, according to the statement.

Following this success, he loaded the new telescope software and practiced maneuvers to simulate true science observations. This ensured that the telescope was ready for action, working on three gyros.

In the meantime, other members of the group focused Hubble on using a single gyro. Although these preparations are unnecessary, today the NASA officials will be inevitably a kind of gyro in a moment, and now the team will be ready.

"Many members of the group worked personal sacrifices and off-shifts to ensure the health and safety of the observatories while identifying a safe and effective way," said Pat Crouse, Hubble's project director.

"Gyro recovery is the only one in the life expectancy of the observatory, but Hubble has three types of gyro production and the main goal of extending this productive period is the mission," he said. "Hubble continues to make amazing discoveries in a kind of gyro, but because of its overwhelming role and role, today is not the time."
