Fine Guidance Sensor (HST)

STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final space shuttle mission to the Hubble Space Telescope (HST).
A fine guidance sensor (FGS) is an instrument on board a space telescope that provides high-precision pointing information as input to the observatory's attitude control systems.
 FGSs have been deployed on the Hubble Space Telescope, and will be deployed with a different technical approach on the James Webb Space Telescope.
 The system on Hubble uses an interferometric instrument
The Guide Star Catalog (GSC), also known as the "Hubble Space Telescope, Guide Catalog" ("HSTGC"), is a star catalog compiled to support the Hubble Space Telescope with targeting off-axis stars.
 GSC-I contained approximately 20,000,000 stars with apparent magnitudes of 6 to 15.
 GSC-II contains 945,592,683 stars out to magnitude 21.
 As far as possible, binary stars and non-stellar objects have been excluded or flagged as not meeting the requirements of Fine Guidance Sensors.
 This is the first full sky star catalog created specifically for navigation in outer space.
Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer.
 He played a crucial role in establishing the fields of extragalactic astronomy and observational cosmology and is regarded as one of the most important astronomers of all time.
Hubble Live, fully titled Hubble Live: The Final Mission, was a one-hour live American television special presentation that premiered on May 11, 2009 on the Science Channel.
 The program covered the launch of Space Shuttle "Atlantis" on NASA's Servicing Mission 4 (HST-SM4), the eleven-day fifth and final mission to repair the Hubble Space Telescope.
 The program was hosted by Josh Zepps, who is the host of science news series "Brink", and featured interviews with NASA astrophysicist and space telescope expert Kim Weaver and former NASA astronaut Paul William Richards.
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.
Michael L. Weiss is an American engineer who is known for his contributions to on-orbit satellite servicing missions, particular of the Hubble Space Telescope.
 Weiss most recently served as deputy program director on the Hubble Space Telescope program at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST; in orbit since 1990) and for the James Webb Space Telescope (JWST; scheduled to be launched in 2018).
 STScI is located on the Johns Hopkins University Homewood Campus in Baltimore, Maryland and was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA).
 Today, in addition to performing continuing science operations of HST and preparing for scientific exploration with JWST, STScI manages and operates the Mikulski Archive for Space Telescopes (MAST), the Data Management Center for the Kepler mission and a number of other activities benefiting from its expertise in and infrastructure for supporting the operations of space-based astronomical observatories.
 Most of the funding for STScI activities comes from contracts with NASA's Goddard Space Flight Center but there are smaller activities funded by NASA's Ames Research Center, NASA’s Jet Propulsion Laboratory, and the European Space Agency (ESA).
 The staff at STScI consists of scientists (mostly astronomers and astrophysicists), software engineers, data management and telescope operations personnel, education and public outreach experts, and administrative and business support personnel.
 There are approximately 100 Ph.D. scientists working at STScI, 15 of which are ESA staff who are on assignment to the HST project.
 The total STScI staff consists of about 450 people.
Rodger Evans Doxsey (March 11, 1947 – October 13, 2009) was an American physicist and astronomer who made major contributions to the scientific and operational success of NASA's Hubble Space Telescope (HST).
 He joined the HST Project at the Space Telescope Science Institute (STScI), in Baltimore, Maryland, in 1981, and was head of the Hubble Missions Office at his death.
Fine Guidance Sensor (FGS) for the Hubble Space Telescope is a system of three instruments used for pointing the telescope in space, and also for astrometry and its related sciences.
 Each FGS uses a combination of optics and electronics to provide for pointing the telescope at a certain location in the sky.
 There are three Hubble FGS, and they have been upgraded over the lifetime of the telescope by manned Space Shuttle missions.
 The instruments can support pointing of 2 milli-arc seconds (units of degree).
 The three FGS are part of the Hubble Space Telescope's pointing control system, aka PCS.
 The FGS function in combination with the Hubble main computer and gyroscopes, with the FGS providing data to the computer as sensors which enables the HST to track astronomical targets.
