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
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.
Hubble Space Telescope precision stellar distance measurement has been extended 10 times further into the Milky Way. [ 10 ] The motion of the Sun through space provides a longer baseline of the parallax triangle that will increase the accuracy of parallax measurements, known as secular parallax .
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 .
He is an advocate for science education and has lectured internationally on the discoveries of the Hubble Space Telescope. [10] In 1996, Williams made the controversial decision to offer the director's discretionary time on the Hubble Space Telescope to two competing teams using distant supernovae to determine the universe's expansion rate ...
The Wide Field Camera 3 (WFC3) is the Hubble Space Telescope's last and most technologically advanced instrument to take images in the visible spectrum. It was installed as a replacement for the Wide Field and Planetary Camera 2 during the first spacewalk of Space Shuttle mission STS-125 (Hubble Space Telescope Servicing Mission 4) on May 14 ...
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.
Dr. Bless died in 2015, and his contributions to the Hubble Space Telescope and the HSP instrument were noted in news media. [2] He worked at the University of Wisconsin–Madison, and the HSP was the lightest and least expensive of the launch instruments. [2] The HSP instrument is located as of 2015 at the University of Wisconsin-Madison's ...
