when was the hubble space telescope launched and when will it stop operating
Hubble Space Telescope The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.[6]
James Webb Space Telescope In December 2016, NASA announced that the JWST had passed major milestones, including completion of its primary mirror and integration of science instruments with the payload module, and had begun undergoing acoustic and extreme vibration testing to simulate launch conditions.[12][13] In March 2018, NASA delayed the JWST's launch an additional year after the telescope's sunshield ripped during a practice deployment and the sunshield's cables did not sufficiently tighten.[14] The JWST is currently scheduled to launch in May 2020.[3][4][15]
