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 Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based ...
Hubble Space Telescope in the cargo bay of Discovery. STS-31 was launched on April 24, 1990 at 12:33:51 UTC (8:33:51 am EDT, local time at the launch site). A launch attempt on April 10, 1990, was scrubbed at T−4 minutes for a faulty valve in auxiliary power unit (APU) number one. The APU was eventually replaced, and the Hubble Space ...
STS-82 was the 22nd flight of the Space Shuttle Discovery and the 82nd mission of the Space Shuttle program.It was NASA's second mission to service the Hubble Space Telescope, during which Discovery's crew repaired and upgraded the telescope's scientific instruments, increasing its research capabilities.
Congress eventually approved funding of US$36 million for 1978, and the design of the LST began in earnest, aiming for a launch date of 1983. During the early 1980s, the telescope was named after Edwin Hubble. Hubble was originally intended to be retrieved and returned to Earth by the Space Shuttle, but the
The near infrared channel has a field of view of 135 by 127 arcsec (2.3 by 2.1 arcminutes) with 0.13 arcsec pixels, and has a much larger field of view than Near Infrared Camera and Multi-Object Spectrometer, which it was designed to largely replace. [2] The near infrared channel is a pathfinder for the future James Webb Space Telescope. [3]
Hubble has two identical SSATs onboard and can operate with only one. The SSATs send data from Hubble through NASA's Tracking Data Relay Satellite System (TDRSS) to the ground. The new transmitter replaced one that failed in 1998. The SSAT weighs 3.9 kilograms (8.6 lb) and is 14 by 8 by 2 + 3 ⁄ 4 inches (356 by 203 by 70 mm).
By 17:24 UTC, Hoffman had finished replacing RSU-2 (containing Gyros 2–3 and 2–4) and then replaced RSU-3 (containing Gyros 3–5 and 3–6). The astronauts then spent about 50 minutes preparing equipment for use during the second space walk and then replaced a pair of electrical control units (ECUs) (ECU-3 and ECU-1) that control RSU-3 and ...
Launch was planned for 2019, [20] [21] [22] but the project's website is now defunct and no updates have been provided on the fate of the effort. Mid/late-2021 – Science first light of the Vera C. Rubin Observatory is anticipated for 2021 with full science operations to begin a year later.
