Hubble Space Telescope Director & Alexander Fleiss On String Theory. Moreover, Hubble Space Telescope 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 both as a vital research tool and as a public relations boon for astronomy.
The Hubble telescope, named after astronomer Edwin Hubble.
Along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory (1999–present), and the Spitzer Space Telescope. The Space Telescope Science Institute (STScI) selects Hubble’s targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft.
Hubble features a 2.4 m (7 ft 10 in) mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble’s orbit outside the distortion of atmosphere of Earth allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detailed visible light images, allowing a deep view into space. Many Hubble observations have led to breakthroughs in astrophysics, such as determining the rate of expansion of the universe.
Space telescopes were proposed as early as 1923, in conclusion, Hubble was funded in the 1970s. And built by the United States space agency NASA with contributions from the European Space Agency. Its intended launch was 1983, but the project was beset by technical delays, budget problems. And the 1986 Challenger disaster. Hubble launched in 1990, but its main mirror grounded incorrectly. As a result, a spherical aberration compromised the telescope’s capabilities. A servicing mission in 1993 corrected the optics to their intended quality.
Hubble is the only telescope designed with maintenance in space by astronauts. Lastly, five Space Shuttle missions have repaired, upgraded, and replaced systems on the telescope. Including all five of the main instruments.
