The Hubble Space Telescope (HST; also known colloquially as "the Hubble" or just "Hubble") is a space telescope that was carried into orbit around the Earth by the Space Shuttle Discovery in April 1990. It is named for the American astronomer Edwin Hubble. Hubble's position outside the Earth's atmosphere allows it to take extremely sharp images and, although not the first space telescope to be deployed, Hubble has become one of the most important instruments in the history of astronomy. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image of the universe's most distant objects ever made. Many observations made using the telescope have led to breakthroughs in astrophysics.
The construction and launch of the Hubble was beset by delays and budget problems. Then, soon after its 1990 launch, it was found that the main mirror suffered from spherical aberration due to faulty quality control during its manufacturing, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality and became a vital research tool as well as a public relations boon for astronomy. The HST is part of NASA's Great Observatories series, with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope. Hubble is a collaboration between NASA and the European Space Agency.
The Hubble is the only telescope ever designed to be serviced in space by astronauts. To date, there have been four servicing missions, with a fifth and final mission planned for September 2008. Servicing Mission 1 took place in December 1993 when Hubble's imaging flaw was corrected. Servicing Mission 2 occurred in February 1997 when two new instruments were installed. Servicing Mission 3 was split into two distinct missions: SM3A occurred in December 1999 when urgently needed repairs were made to Hubble; and then SM3B followed in March 2002 when the Advanced Camera for Surveys (ACS) was installed.
Since SM3B, the Hubble has lost use of two major science instruments and is operating with viewing restrictions because of rate-sensing gyroscope failures. There are six gyroscopes onboard Hubble and three are normally used for observing. However, after further failures, and in order to conserve lifetime, a decision was taken in August 2005 to switch off one of the functioning gyroscopes and operate Hubble using only 2 gyros in combination with the Fine Guidance Sensors. This mode retains the excellent image quality of Hubble, and provides a redundancy should it be needed. Further redundancy is available now that an operational mode requiring only one gyro has been developed and tested. Six new gyroscopes are planned to be installed in SM4.
The two instruments that have failed are the Space Telescope Imaging Spectrograph (STIS) which stopped working in August 2004 and the Advanced Camera for Surveys (ACS) which ceased operations in January 2007 (operations were later restored for its little used far-ultraviolet mode). Currently (mid-2007) Hubble observations are being taken with the Wide Field and Planetary Camera 2 (WFPC2) and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS). Astrometry is being carried out with the Fine Guidance Sensor (FGS). Without a reboost to increase the diameter of its orbit, drag will cause Hubble to re-enter the Earth's atmosphere sometime after 2010.
Following the 2003 Columbia Space Shuttle disaster, the fifth servicing mission (SM4), initially planned for 2004, was canceled on safety grounds. NASA determined that a manned mission would be too dangerous, due to a lack of access to the International Space Station (ISS), which can serve as a safe haven for an astronaut crew. The Shuttle cannot travel between the Hubble and ISS orbits. The organization later reconsidered this position, and, on October 31, 2006, NASA administrator Mike Griffin gave the green light for a final Hubble servicing mission to be flown by Atlantis. The mission is now planned for August 2008. As a safety precaution, NASA will have the orbiter Endeavour standing by at Launch Complex 39B to provide rescue in the event of an emergency. The planned repairs to the Hubble will allow the telescope to function until at least 2013, when its successor, the James Webb Space Telescope (JWST), is due to be launched. The JWST will be far superior to Hubble for many astronomical research programs, but will only observe in infrared, so it will not replace Hubble's ability to observe in the visible and ultraviolet parts of the spectrum.

A British professor and expert on the health effects of ionizing radiation told Alex Jones today evidence points toward a nuclear explosion occurring at the Fukushima Daiichi complex. Two explosions at the plant in March were described as hydrogen gas explosions by Japanese officials and the corporate media.
Professor Chris Busby on the Alex Jones Show, April 12, 2011.
Citing data collected by two Russian scientists, Professor Chris Busby told Alex Jones and his audience the explosions at Fukushima were nuclear. The Russian scientists, Sergey A. Pakhomov and Yuri V. Dubasov of the VG Khlopin Radium Institute in Saint Petersburg, examined data related to the explosion at Chernobyl.
Japanese nuclear safety agency raises crisis level of Fukushima Daiichi power plant accident from 5 to 7.
Using ratios of the radionuclides Xenon 133 and Xenon 133m which they measured by gamma spectrometer, the Russians demonstrated that the Chernobyl explosion was a fission criticality explosion and not principally a hydrogen explosion as has been claimed.
A d v e r t i s e m e n t
"I believe that the explosion of the No 3 reactor may have also involved criticality but this must await the release of data on measurements of the Xenon isotope ratios," he writes in a statement on Fukushima and Chernobyl emailed to Infowars****.
Busby further notes that the surface contamination and of dose rates 60 kilometers out from the Fukushima site on March 17 exceeded that released at Chernobyl.
He explains in his statement that the damaged reactors at Fukushima "are now continuing to fission. It is hoped that there will be no separation of plutonium and possible nuclear explosion. I feel that this is unlikely now." Short of an actual plutonium explosion, the reactors remain open to the air and will continue to "fission and release radionuclides for years unless something drastic is done."
Dr. Busby noted a precedent for the dire scenario now unfolding -- a nuclear explosion at a plutonium production reprocessing plant in the former Soviet Union in 1957.
The incident at the Mayak facility was the second-worst nuclear accident in history after the Chernobyl disaster. The explosion released 50-100 tonnes of high-level radioactive waste and contaminated a huge territory in the eastern Urals. The Soviets kept the explosion secret for 30 years. According to a report on the accident, about 400,000 people in the region were irradiated following the explosion and other incidents at the plant.

Dr. Busby told Alex Jones that short of actual isotope readings, he cannot definitely state that the explosions at Fukushima were nuclear, although he believes they were. "We don't have evidence of that," he concluded, "we would need to have the Xenon isotope ratios."

Space weather in the palm of your hand, a new use for forty year old Russian rocket engines, and our moon is AWESOME! I'm Benjamin Higginbotham and this is your Spacevidcast SpacePod for December 22nd, 2010.
Orbital Sciences Corporation on Sunday executed a successful test of their AJ26 rocket engine at the NASA Stennis Space Center in Mississippi. The kerosene based engine is the first stage of the Taurus II rocket in development by Orbital to launch the Cygnus robotic resupply spacecraft to the International Space Station. The test lasted 55 seconds while the AJ26 engine was pushed to 108% of it's baseline thrust. Sunday was the first time the thrust vector control system was tested, a system vital for spacecraft steering during the four minute first stage burn. According to Orbital Sciences, all primary objectives were met successfully. Two AJ26 engines, which are modified Russian NK-33 engines originally designed for the Soviet Union's N1 moon rocket, will be used on each Taurus II. How do you make an NK-33 into an AJ26? Aerojet, the company behind the AJ26, test fires an NK-33 in Russia and if cleared for use, removes some of the original equipment, replaces the electronics and gimbal system, and clears the engine to use kerosene. Orbital will be test firing an AJ26 again in mid-January to check engine control valve tuning. The maiden voyage of Taurus II is scheduled to take place in the second half of 2011, from Wallops Island, Virginia.
Yesterday we talked about a great app for iPhone users called MissionClock. But what about a space geek app for the millions of Android users out there, like me? A company in Colorado has released an app for Android phones that allows users to see near real time images from the sun through the Solar Dynamics Observatory. The application was commissioned by NASA and developed by Atmospheric and Space Technology Research Associates, or ASTRA. According to the head of ASTRA, not only are scientists using it but amateurs and novices with an interest in space weather can also download and use the app. No stranger to space weather software, ASTRA also develops an Android application, aptly called SpaceWeather, that accesses ASTRA's network, and models space weather conditions, right in the palm of your hand. Look for both applications in the Android Marketplace.
Yesterday we covered the use of LRO's LOLA instrument to create maps of the moon with unprecedented accuracy. Well, another map release was made; this time by the European Space Agency or ESA. GlobCover 2009 is an improvement upon the same effort from five years ago, called GlobCover 2005. Using a years worth of data from the Medium Resolution Imaging Spectrometer on ESA's Envisat satellite, ESA and Université catholique de Louvain created the sharpest global land cover map ever created. The data was captured between Janurary 1st and December 31st 2009. These maps, which are freely available from ESA's website, can be used in any number of applications ranging from environmental studies to managing natural resources.
And speaking of the moon, I can't think of a better way to end this SpacePod than with the Winter Solstice Lunar Eclipse. If you missed this one, your next viewing opportunity for a Lunar Eclipse that happens on Winter Solstice will be December 21st, 2094. Enjoy.
