Hubble+Telescope

__**Hubble Telescope**__ The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by a space shuttle in 1990. 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 Mission length 20 years, 6 months, and 10 days elapsed. A low Earth orbit (LEO) is generally defined as an orbit within the locus extending from the Earth’s surface up to an altitude of 2,000 km. Given the rapid orbital decay of objects below approximately 200 km, the commonly accepted definition for LEO is between 160 - 2,000 km(100 - 1,240 miles) above the Earth's surface. Orbit velocity: 7,500 m/s (25,000 ft/s) Acceleration due to gravity: 8.169 m/s2 (26.80 ft/s2) Location: Low Earth orbit [] []
