The Hubble Space Telescope (often referred to as 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 both as a vital research tool and as a public relations boon for … Ver mais Proposals and precursors In 1923, Hermann Oberth—considered a father of modern rocketry, along with Robert H. Goddard and Konstantin Tsiolkovsky—published Die Rakete zu den … Ver mais Within weeks of the launch of the telescope, the returned images indicated a serious problem with the optical system. Although the first images appeared to be sharper than those … Ver mais Since the start of the program, a number of research projects have been carried out, some of them almost solely with Hubble, others coordinated facilities such as Ver mais Key projects In the early 1980s, NASA and STScI convened four panels to discuss key projects.
