Our Window to the Soul of the Universe, The Hubble Space Telescope


Description:

Courtesy of NASA. Hubble's Name: NASA named the world's first space-based optical telescope after American astronomer Edwin P. Hubble (1889—1953). Dr. Hubble confirmed an "expanding" universe, which provided the foundation for the Big Bang theory. Mission: Launch: April 24, 1990 from space shuttle Discovery (STS-31) Deployment: April 25, 1990 Mission Duration: Up to 20 years Servicing Mission 1: December 1993 Servicing Mission 2: February 1997 Servicing Mission 3A: December 1999 Servicing Mission 3B: February 2002 Servicing Mission 4: May 2009 Size: Length: 43.5 ft (13.2 m) Weight: 24,500 lb (11,110 kg) Maximum Diameter: 14 ft (4.2 m) Cost at Launch: $1.5 billion Spaceflight Statistics: Orbit: At an altitude of 307 nautical miles (569 km, or 353 miles), inclined 28.5 degrees to the equator (low-Earth orbit) Time to Complete One Orbit: 97 minutes Speed: 17,500 mph (28,000 kph) Optical Capabilities: Hubble Can't Observe: The Sun or Mercury, which is too close to the Sun Sensitivity to Light: Ultraviolet through infrared (115—2500 nanometers) First Image: May 20, 1990: Star Cluster NGC 3532 Data Statistics: Hubble transmits about 120 gigabytes of science data every week. That's equal to about 3,600 feet (1,097 meters) of books on a shelf. The rapidly growing collection of pictures and data is stored on magneto-optical disks. Power Needs: Energy Source: The Sun Mechanism: Two 25-foot solar panels Power usage: 2,800 watts Pointing Accuracy: In order to take images of distant, faint objects, Hubble must be extremely steady and accurate. The telescope is able to lock onto a target without deviating more than 7/1000th of an arcsecond, or about the width of a human hair seen at a distance of 1 mile. Hubble's Mirrors: Primary Mirror Diameter: 94.5 in (2.4 m) Primary Mirror Weight: 1,825 lb (828 kg) Secondary Mirror Diameter: 12 in (0.3 m) Secondary Mirror Weight: 27.4 lb (12.3 kg) Power Storage: Batteries: 6 nickel-hydrogen (NiH) Storage Capacity: equal to 20 car batteries Stargazer Nation Links: Stargazer Nation Facebook Page - https://www.facebook.com/StargazerNation Stargazer Nation Facebook Group - https://www.facebook.com/groups/1441276202795886/ Facebook Friend Page - https://www.facebook.com/mrstargazer.nation Twitter - https://twitter.com/STARGAZERNATION On Tumblr: http://stargazernation.tumblr.com/ Blogspot - http://stargazernation.blogspot.co.uk/ On Pinterest: http://www.pinterest.com/Stargazernation/ Check out the latest: http://checkoutthelatest.com/MRSTARGAZERNATION Frequency: http://www.frequency.com/mrstargazernation?cid=4-2155340 Ashtar Command Crew: http://www.ashtarcommandcrew.net/profiles/blog/list?user=251glgsbn5l1o YouTube: https://www.youtube.com/user/MRSTARGAZERNATION Science Stage: http://sciencestage.com/stargazernation Before its News: http://beforeitsnews.com/contributor/pages/343/420/stories.html Google Community Group - https://plus.google.com/u/0/b/112543437330458039827/communities/11762178...
