There have been 5 servicing missions, numbered 1, 2, 3A, 3B, and 4.
Space Shuttles Discovery and Atlantis were most often used for HST Servicing Missions, due to their larger cargo bays.
The Hubble telescope was launched in 1990, but faulty optics limited its use until a shuttle mission made repairs in 1993. Other servicing missions improved its onboard instruments. It will be mostly superseded by the James Webb Space Telescope planned for launch around 2018.
The Hubble telescope traveled to space aboard the Space Shuttle Discovery on April 24, 1990, on mission STS-31. There were four subsequent shuttle servicing missions, the last by STS-125 on May 13-19, 2009.
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.
The Space Shuttle was used by NASA for human spaceflight missions, such as deploying satellites, conducting research in microgravity, and servicing the Hubble Space Telescope. It served as a reusable spacecraft for launching missions into space and returning them safely back to Earth.
Yes, the Hubble Space Telescope has been repaired several times since its launch in 1990. The last servicing mission was in 2009.
The Hubble Space Telescope was repaired and serviced by astronauts during a series of Space Shuttle missions. Notably, five servicing missions took place between 1993 and 2009, with astronauts conducting repairs, upgrades, and maintenance tasks. NASA's crews, including notable astronauts like John Grunsfeld and Story Musgrave, played key roles in these missions, ensuring the telescope's continued functionality and longevity.
Atlantis is going to the Hubble Space Telescope. This will be the final servicing mission and no spacecraft will travel to Hubble after this.
It took 20 years to build and launch the hubble telescope, a total of seven years after the proposed launched date in 1983, and even then it was not operational as one of it's main mirrors had been fitted incorectly, and it took another three years for a servicing mission made it fully operational. I have no idea
The total cost of the Hubble Space Telescope, including development, construction, and maintenance over its lifetime, is estimated to be around $10 billion. This includes the cost of the initial launch in 1990 and the subsequent servicing missions.
The trouble experienced with the Hubble Space Telescope included a flaw in its primary mirror, which caused blurry images. This issue was corrected during a servicing mission in 1993. Additionally, the telescope has faced challenges with a few component failures, which have been addressed through subsequent servicing missions.
The HST was carried aboard the Space Shuttle and placed in orbit in April of 1990. Four Shuttle missions visited it between 1993 and 2002 for service, upgrade, and maintenance. A planned fifth mission was cancelled in the aftermath of the Columbia disaster. However, after much public discussion, NASA administrator Mike Griffin approved one final servicing mission. It was completed in 2009, and there won't be any more. The Hubble telescope is now expected to function until at least 2014, and possibly 2020. Its scientific successor, the James Webb Space Telescope, is scheduled to be launched in 2018.
