Astronauts fixed the Hubble Space Telescope during a series of servicing missions conducted by NASA. They conducted spacewalks to replace and repair critical components, including gyroscopes, batteries, and the camera systems. Notably, in 1993, they installed the Corrective Optics Space Telescope Axial Replacement (COSTAR) to fix the telescope's blurry vision caused by a flawed mirror. These missions significantly extended Hubble's operational life and improved its imaging capabilities.

What was found to be out of focus after it was launched?
The Hubble Space Telescope was found to be out of focus after it was launched in 1990, due to a flaw in its primary mirror. This issue was corrected in 1993 during a servicing mission, which installed corrective optics to fix the problem and improve the telescope's imaging capabilities.
What are 3 problems that hubble encountered?
The Hubble Space Telescope faced several significant challenges during its operational life. Firstly, its initial launch in 1990 revealed that its primary mirror had a spherical aberration, resulting in blurry images. Secondly, the telescope experienced various electronic and software issues over the years, which required multiple servicing missions to fix. Lastly, Hubble's aging components and the need for upgrades have posed ongoing challenges to maintain its functionality and scientific capabilities.
How did they fix the Hubble Telescope?
The slight optical defect (known as a spherical aberration, and less than 4 microns, 1/5 the thickness of a human hair) discovered in the Hubble's primary mirror after it was deployed in space, was corrected by a system known as COSTAR (Corrective Optics Space Telescope Axial Replacement). Built by Ball Aerospace, it was manufactured and tested between the Hubble's first deployment and her First Servicing Mission in 1993.COSTAR (since replaced, as all Hubble instruments installed after the FSM have corrective optics) worked much like corrective eyeglasses, using a system of tiny mirrors to correct for the flaw. The result of COSTAR's installation (and all of us who worked on it waited with our breath held until it was operational and the first pictures were in) was nothing less than spectacular, restoring Hubble to its original design specifications.
How much did the Hubble telescope cost to build?
It was actually 1.5 billion dollars. However, first images came back from the Hubble blurred, due to a faulty mirror. This was a big and even dangerous job to fix, and on top of that, it brought the total cost up to around $6 Billion USD. Ouch.
What do shuttles do in space?
space shuttles fix all kinds off satelites they help fix any kind of spacecraft.the space shuttles have been launching since 1977 from NASA.space shuttles are very useful space craft to help fix things in outer space .by George Philip if you like space shuttles a lot there is a Lego set
How is the hubble telescope getting fixed?
when there are problems with the hubble space telescope, astronomers send astronauts to go fix the problem.
What shuttle was used to repair the Hubble Space Telescope in 1993?
The Space Shuttle Endeavour was used to repair the Hubble Space Telescope in 1993 during the STS-61 mission. The crew installed corrective optics to fix the telescope's flawed vision.

How did astronomers fix the telescope for the Hubble Space Telescope?
By giving it "eyeglasses" just like your optometrist does to fix your vision. Initially by replacing the "High Speed Photometer" unit with the "Corrective Optics Space Telescope Axial Replacement" unit. Later instruments had their own "eyeglasses", making the "Corrective Optics Space Telescope Axial Replacement" unit unnecessary and it was replaced with the new "Cosmic Origins Spectrograph" unit.
Why do they need to repair the Hubble space telescope?
The best known Hubble repair mission was to install a fix to some flawed optics aboard the telescope. Other missions have been to replace other aging hardware and install more capable equipment for more advanced research.
Where was the Hubble Space Telescope built?
Once the Space Telescope project had been given the go-ahead, work on the program was divided among many institutions. Marshall Space Flight Center (MSFC) was given responsibility for the design, development, and construction of the telescope, while theGoddard Space Flight Center was given overall control of the scientific instruments and ground-control center for the mission. MSFC commissioned the optics company Perkin-Elmer to design and build the Optical Telescope Assembly (OTA) and Fine Guidance Sensors for the space telescope. Lockheed was commissioned to construct the spacecraft in which the telescope would be housed. Perkin-Elmer was commissioned to build the optical components of the Hubble Space Telescope. The construction of the main mirror was begun in 1979 and polishing completed in 1981 in Danbury Connecticut.
What will happen to Hubble Space Telescope?
They will pull it back to Earth. It will get burned up long before it hits the ground. The reason for doing this is because the HST is getting old and it would take too much time and money to fix it.

How do you fix telescope on club penguin ski mountain?
Use your rench to fix the telescope
Why did the Hubble space telescope fail?
the initial problem was=== the reflecting (lens/mirror) was improperly ground due to the thickness of a 25 cent washer used in the grinding machine that made the lens. the problem was solved by insalling corrective (lenses/mirrors) shaped like pringles potato chips. sounds crazy but its true. bob winters hannacroix n y. there is a particular name for this shape but i cant remember it except that its l o n g.
What are the disadvantages of a telescope in space have over a telescope on Earth?
In space, has the chance of being hit by debree, but you can get better images, and better info. Also if something goes wrong it will take awhile to fix it. On Earth, Can be fixed fast, but cannot get as better info from in space telescopes.
