Jeffrey Alan Hoffman is an American former NASA astronaut and currently a professor of aeronautics and astronautics at MIT. Hoffman made five flights as a space shuttle astronaut, including the first mission to repair the Hubble Space Telescope in 1993, when the orbiting telescope's flawed optical system was corrected.
STS-51-D was the sixteenth flight of the shuttle and fourth for the Space Shuttle Discovery. Its mission was to deploy a number of 10 satellites. The landing suffered extensive brake damaged and a ruptured tire. All subsequent landings had to be done at the Edwards Air Force Base until the development and implementation of nose steering.Low Earth Orbit
STS-61 was the first Hubble Space Telescope servicing mission, and the fifth flight of the Space Shuttle Endeavour. The mission launched on 2 December 1993 from Kennedy Space Center in Florida. The mission restored the spaceborne observatory's vision, marred by spherical aberration, with the installation of a new main camera and a corrective optics package. This correction occurred more than three and a half years after the Hubble was launched aboard STS-31 in April 1990. The flight also brought instrument upgrades and new solar arrays to the telescope.Low Earth Orbit
The National Aeronautics and Space Administration is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research. NASA have many launch facilities but most are inactive. The most commonly used pad will be LC-39B at Kennedy Space Center in Florida.
