The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.
STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final Space Shuttle mission to the Hubble Space Telescope (HST). The launch of the Space Shuttle Atlantis occurred on May 11, 2009, at 2:01 pm EDT. [2] [3] [4] Landing occurred on May 24 at 11:39 am EDT, [5] with the mission lasting a total of just under 13 days ...
STS-61 was NASA's first Hubble Space Telescope servicing mission, and the fifth flight of the Space Shuttle Endeavour.The mission launched on December 2, 1993, from Kennedy Space Center (KSC) in Florida.
Responsible for all Space Shuttle-based activities related to construction and operation of the Space Station, including logistics and transfer items stored in a multi-purpose logistics module (MPLM) or Spacehab. Also responsible for all Shuttle payloads, from Spacehab to the Hubble Space Telescope to deployable satellites. On Shuttle missions ...
STS-31 was the 35th mission of NASA's Space Shuttle program and the tenth flight of the Space Shuttle Discovery. The primary purpose of this mission was the deployment of the Hubble Space Telescope (HST) into low Earth orbit. Discovery lifted off from Launch Complex 39B on April 24, 1990, from Kennedy Space Center, Florida.
There were many problems, delays, and cost increases in the program, and the Challenger disaster delayed the availability of the launch vehicle. The Hubble Space Telescope was launched in April 1990, but gave flawed images due to a flawed primary mirror that had spherical aberration. The defect was found when the telescope was in orbit.
NRO led the development of a computer controlled mirror polishing technique, which was subsequently also used for the polishing of the primary mirror of the Hubble Space Telescope. [30] Later satellites had larger mirrors, with a diameter of around 2.9 to 3.1 meters (110 to 120 in). [31]
The second mission in the Polaris Program will launch via a Falcon 9 Block 5 vehicle with a Crew Dragon capsule. SpaceX and Polaris had studied a crewed mission to lift the Hubble Space Telescope into a higher orbit to prevent it from burning up in the atmosphere, [4] [5] but this option was rejected by NASA in June 2024.
