The Hubble Space Telescope (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 as a vital research tool and as a public relations boon for astronomy .
A fine guidance sensor (FGS) is an instrument on board a space telescope that provides high-precision pointing information as input to the telescope's attitude control systems. Interferometric FGSs have been deployed on the Hubble Space Telescope; a different technical approach is used for the James Webb Space Telescope's FGSs.
From the center to outer edge of the FGS field of view is 14.1 arcminutes [1] This is a diagram of the field of view of each Hubble Space Telescope instrument, including the three FGS instruments (FGS field of view(s) highlighted in yellow) A Fine Guidance Sensor being refurbished between servicing missions SM3A and SM4 A fine guidance sensors in space on STS Servicing Mission 2 in 1997
NASA's James Webb Space Telescope is by far the most powerful observatory ever launched into space.. Even Webb's very first images show why NASA spent 25 years and $10 billion. The Hubble Space ...
A space telescope (also known as space observatory) is a telescope in outer space used to observe astronomical objects. Suggested by Lyman Spitzer in 1946, the first operational telescopes were the American Orbiting Astronomical Observatory , OAO-2 launched in 1968, and the Soviet Orion 1 ultraviolet telescope aboard space station Salyut 1 in 1971.
Planetary science is the study of the assemblage of planets, moons, dwarf planets, comets, asteroids, and other bodies orbiting the Sun, as well as extrasolar planets. The Solar System has been relatively well-studied, initially through telescopes and then later by spacecraft. This has provided a good overall understanding of the formation and ...
NICMOS was installed on Hubble during its second servicing mission in 1997 along with the Space Telescope Imaging Spectrograph, replacing two earlier instruments.. NICMOS in turn has been largely superseded by the Wide Field Camera 3, which has a much larger field of view (135 by 127 arcsec, or 2.3 by 2.1 arcminutes), and reaches almost as far into the in
The Hubble Space Telescope received the Soft-Capture Mechanism (SCM) on STS-125. [7] The SCM is meant for unpressurized docking, but uses the LIDS interface to reserve the possibility of an Orion docked mission. [7] The docking ring is mounted on Hubble's aft bulkhead. [7] It may be used for safely de-orbiting Hubble at the end of its service ...
