NASA's Hubble Space Telescope, whose original camera and backup camera were designed, built, and managed by the Jet Propulsion Laboratory returned on Friday, October 26, after a three-week break when one of its gyroscopes did not work Normal operation back.
NASA announced that the Space Telescope has completed its first scientific observations since its collapse on Saturday, October 27. at 1
NASA said the Hubble task force at JPL successfully restored a backup gyroscope or gyroscope, which they activated remotely on October 6 to replace the gyro that had failed the day before.
Unexpectedly, the backup turned too fast, beyond the actual and intended speeds, so the team had to run tests. Www.moviesfilmonline.com / de / movies / … of – the – opera He tests Hubble to perform numerous maneuvers and switch the gyroscope between different modes of operation – methods the team believes that they have successfully eliminated the too high rotation values.
After a series of additional maneuvers to check gyro stability The team reversed the gyroscope and then started again.
On Friday, the team began restoring the scientific instruments to standard operating status. Hubble successfully completed maneuvers to finish the first scientific observations, and the telescope collected its first scientific data since October 5. The Space Telescope is now back in normal operation mode – with three fully functional gyroscopes, NASA's
Hubble original camera, the Wide Field / Planetary Camera (WPFC), was designed and engineered by JPL engineers and carried by the Space Telescope when it was launched April 24, 1990 aboard the space shuttle Discovery launched from the Kennedy Space Center in Florida.
When the first pictures of the WPFC – now labeled WPFC 1 to distinguish them from the other two cameras – came down from Hubble about a month later, mission scientists discovered that there was a mistake in the mirror of the camera and the pictures that she did was not as good as NASA had promised.
NASA announced the problem to the world in June 1990, while engineers at JPL sought a solution 59003] Former JPL director Lew Allen, who had since passed away, headed a panel to investigate the problem, but John Trauger, now Senior Research Scientist at JPL, suggested to NASA that NASA correct Hubble's "spherical aberration" by reflecting a small mirror in WFPC2, a replacement camera that JPL has been developing since 1985 when working on WFPC1.
Ultimately, Allen's committee of inquiry found the specific cause of Hubble's aberration, and Trauger and his team set to work on the optics of the still-to-be-made WFPC2  On December 2, 1993, the Atlantis Space Shuttle launched the Goddard Space Flight Center with WFPC2 , In the following days, astronauts picked up WPFC1 and put the new camera on Hubble.
Sixteen days later, the JPL team celebrated with great joy as Hubble's first images of the new camera arrived – they were so keen on the team they knew they had succeeded.
WFPC2 was eventually removed and replaced by Wide Field Camera 3 in May 2009 as part of the mission's first spacewalk. WFPC2 is now on display at the Smithsonian National Air and Space Museum.
Since the Hubble Mission began in 1990, the Space Telescope has made more than 1.3 million observations and has helped to publish more than 15,000 scientific papers.
