Hubble Space Telescope (SCRS). , the Trump Administration is considering a proposal by the Sierra Nevada Corporation to use a manned version of its Dream Chaser spacecraft to service "Hubble" some time in the 2020s both as a continuation of its scientific capabilities and as insurance against any malfunctions in the to-be-launched James Webb Space Telescope. There is no direct replacement to Hubble as an ultraviolet and visible light space telescope, because near-term space telescopes do not duplicate Hubble's wavelength coverage (near-ultraviolet to near-infrared wavelengths), instead concentrating on the farther infrared bands. These bands are preferred for studying high redshift and low-temperature objects,
Space Shuttle program OV-101) was rolled out on September 17, 1976, and later conducted a successful series of glide-approach and landing tests in 1977 that were the first real validation of the design. All Space Shuttle missions were launched from the Kennedy Space Center (KSC). The weather criteria used for launch included, but were not limited to: precipitation, temperatures, cloud cover, lightning forecast, wind, and humidity. The Shuttle was not launched under conditions where it could have been struck by lightning. The first fully functional orbiter was "Columbia" (designated OV-102), built in Palmdale, California. It was delivered to Kennedy Space Center (KSC) on
