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-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.
The Hubble Space Telescope, deployed during Mission STS-31 in April 1990, was the first. CGRO was launched on a two-year mission to search for the high-energy celestial gamma ray emissions, which cannot penetrate Earth's atmosphere. At about 16,000 kg (35,000 lb), CGRO was the heaviest satellite to be deployed into low Earth orbit from the ...

The Hubble Space Telescope was deployed in April 1990 during STS-31. It was designed to undergo periodic servicing and upgrading over its projected 15-year lifespan, with first servicing performed during STS-61 in December 1993. Hawley, who originally deployed the telescope, operated the orbiter Remote Manipulator System arm on STS-82 to ...
To mark 34 years of service, the Hubble Space Telescope captured an image of the Little Dumbbell Nebula, which may contain evidence of one star devouring another.
Webb's delays and cost increases have been compared to those of its predecessor, the Hubble Space Telescope. When Hubble formally started in 1972, it had an estimated development cost of US$300 million (equivalent to $2,185,203,000 in 2023), but by the time it was sent into orbit in 1990, the cost was about four times that.
