Correcting the flawed optics of the Hubble Space Telescope (HST) in its first years played a significant role in the birth of Webb. [81] In 1993, NASA conducted STS-61, the Space Shuttle mission that replaced HST's camera and installed a retrofit for its imaging spectrograph to compensate for the spherical aberration in its primary mirror.
Use of NASA logos, insignia and emblems is restricted per U.S. law 14 CFR 1221.; The NASA website hosts a large number of images from the Soviet/Russian space agency, and other non-American space agencies.
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.
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory , OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971.
The telescope is designed to last at least five and a half years (six months calibration plus five years science operations), but with a goal of ten years. [4] The limiting factor is expected to be fuel to maintain its halo orbit, of which there is enough for at least ten years. [4]
1883 – Andrew Ainslie Common uses the photographic dry plate process and a 36-inch (91 cm) reflecting telescope in his backyard to record 60 minute exposures of the Orion nebula that for the first time showed stars too faint to be seen by the human eye.
The telescope was turned on again in 2013, and by December 2013 the telescope had cooled down sufficiently to be able to resume observations. [60] Between then and May 2017, the telescope made almost 640,000 detections of over 26,000 previously known objects including asteroids and comets. [ 60 ]
Webb directed NASA's undertaking of the goal set by Kennedy of landing an American on the Moon before the end of the 1960s through the Apollo program. For seven years after Kennedy's announcement on May 25, 1961, of the goal of a crewed lunar landing, Webb lobbied for support for NASA in Congress, until he left NASA in October 1968.
