Hubble Space Telescope - Better Than Ever!

Final Servicing Mission. --- Please subscribe to Science & Reason: • http://www.YouTube.com/Best0fScience • http://www.YouTube.com/ScienceMagazine • http://www.YouTube.com/ScienceTV • http://www.YouTube.com/FFreeThinker --- "Improved Hubble Shows Evidence of Dark Matter" • http://www.youtube.com/user/tdarnell#play/uploads/2/3wluv08tDhU • http://www.deepastronomy.com/ "When Hubble Opened its New Eyes" • http://www.youtube.com/AndromedasWake • http://www.youtube.com/watch?v=9bytNgT7l8k "The Hubble Space Telescope - Rebirth of an Icon (Hubblecast 30)" • http://www.youtube.com/ESOcast • http://www.youtube.com/watch?v=Hjy7YSIH-GI --- The Hubble Space Telescope (HST) is a space telescope that was carried into orbit by the space shuttle in April 1990. It is named after the American astronomer Edwin Hubble. Although not the first space telescope, the 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 a collaboration between NASA and the European Space Agency, 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. Space telescopes were proposed as early as 1923. The Hubble was funded in the 1970s, with a proposed launch in 1983, but the project was beset by technical delays, budget problems, and the Challenger disaster. When finally launched in 1990, scientists found that the main mirror had been ground incorrectly, severely compromising the telescope's capabilities. However, after a servicing mission in 1993, the telescope was restored to its intended quality. Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely sharp images with almost no background light. Hubble's Ultra Deep Field image, for instance, is the most detailed visible-light image ever made of the universe's most distant objects. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe. The Hubble is the only telescope ever designed to be serviced in space by astronauts. There have been five servicing missions, the last occurring in May 2009. Servicing Mission 1 took place in December 1993 when Hubble's imaging flaw was corrected. Servicing missions 2, 3A, and 3B repaired various sub-systems and replaced many of the observing instruments with more modern and capable versions. However, following the 2003 Space Shuttle Columbia accident, the fifth servicing mission was canceled on safety grounds. After spirited public discussion, NASA reconsidered this decision, and administrator Mike Griffin approved one final Hubble servicing mission. STS-125 was launched in May 2009, and installed two new instruments and made numerous repairs. The latest servicing should allow the telescope to function until at least 2014, 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 complement (not replace) Hubble's ability to observe in the visible and ultraviolet parts of the spectrum. • http://en.wikipedia.org/wiki/Hubble_Space_Telescope .

Hubble's Successor: The James Webb Space Telescope

http://www.facebook.com/ScienceReason ... Science@ESA (Episode 4): Following The Redshift (Part 2) - Hubble's Successor: The James Webb Space Telescope. In this fourth episode of the Science@ESA vodcast series Rebecca Barnes will identify some of the key discoveries achieved with the famous Hubble Space Telescope, look at the concept of redshift, and meet a new telescope that will be used to uncover the early Universe. --- Please SUBSCRIBE to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- Named in 2002 in honour of NASA's administrator during the Apollo programme, the James Webb Space Telescope (JWST) mission is a collaborative project between the National Aeronautics and Space Administration, the European Space Agency and the Canadian Space Agency. JWST will address many of the outstanding issues of modern astronomy related to the 'Early Universe' and is expected to yield scientific breakthroughs as did its predecessor, the Hubble Space Telescope. JWST will be a general-purpose observatory with a suite of astronomical infrared-sensitive instruments. Compared to existing or planned observatories, JWST will have the unique advantage of combining superb image quality throughout a wide wavelength range, a wide field of view and unparalleled photon sensitivity due to its 6.5-metre diameter telescope primary mirror. http://sci.esa.int/science-e/www/area/index.cfm?fareaid=29 --- The James Webb Space Telescope (JWST) is a planned infrared space observatory, the partial successor to the aging Hubble Space Telescope. The JWST will not be a complete successor, because it will not be sensitive to all of the light wavelengths that Hubble can see. The main scientific goal is to observe the most distant objects in the universe, those beyond the reach of either ground based instruments or the Hubble. The JWST project is a NASA-led international collaboration with contributors in fifteen nations, the European Space Agency (ESA) and the Canadian Space Agency (CSA). Originally called the Next Generation Space Telescope (NGST), it was renamed in 2002 after NASA's second administrator, James E. Webb (1906-1992). Webb had headed NASA from the beginning of the Kennedy administration through the Johnson administration (1961-68), thus overseeing all the manned launches in the Mercury through Gemini programs, until just before the first manned Apollo flight. Current plans call for the telescope to be launched on an Ariane 5 rocket in June 2014, on a five-year mission (10 year goal). The JWST will reside in solar orbit near the Sun-Earth L2 point, which is on a line passing from the Sun to the Earth, but about 1.5 million km farther away from the Sun than is the Earth. This position, which moves around the Sun in exact orbital synchrony with the Earth, will allow JWST to shield itself from infrared from both Sun and Earth, by using a single radiation shield positioned between the telescope and the Sun-Earth direction. http://en.wikipedia.org/wiki/James_Webb_Space_Telescope .

Galileo

Galileo will use the most accurate atomic clock in space to provide the most accurate positioning services. In fact time is the key for satellite navigation systems. The launch of the first pair of Galileo satellites, set for October 20, will open the road for Europe's satellite navigation programme. Another In-orbit Validation pair will be lofted next year and the full constellation will become fully operational with a constellation of 30 spacecraft. Their technologies have already been demonstrated with two precursor satellites GIOVE-A & B. At the heart of each Galileo satellite are four atomic clocks which will ensure that users on Earth to know their position to within a metre. These ultra-precise clocks will all beat in rhythm, rigorously synchronized with the ground network of control stations. That is why Galileo has been described as 'one vast space clock'.

Space Odyssey: Voyage To The Planets 1 - BBC

Space Odyssey: Voyage To The Planets This two-part science fiction docu-drama examines the possibilities of a dangerous, manned space mission to explore the inner and outer planets of the Solar system. Five astronauts pilot the nuclear thermal rocket powered Pegasus spacecraft on a tour of the solar system. Their mission is a collaboration of the NASA, CSA, ESA and РКА space agencies and takes the crew to Venus, Mars, a close flyby of the Sun, Jupiter's moon Io and Europa, Saturn, Pluto, and the fictional Comet Yano-Moore. Most of the planetary destinations the crew reaches are followed by a manned landing there. Prior to the mission large tanks of hydrogen were deposited in stable orbits around the planets to allow the crew to refuel to have sufficient delta-v for the multi-year mission. The crew encounter many hardships and disappointments along the way. A Venus EVA that almost ends in disaster when the lander Orpheus encounters launch delays, the near-loss of the shield during the aerobrake in Jupiter's upper atmosphere (according to the first part of the miniseries) and the loss of samples from Jupiter's moon Io all test the crew's resolve. The most devastating blow comes when the ship's medical officer dies of solar radiation-induced lymphoma in Saturn orbit, forcing the crew to decide whether to continue the mission to Pluto, or abort and return to Earth. In the original British release, the crew decides to press on to Pluto, making history.

Planetary Science: Exploring The Solar System

Science & Reason on Facebook: http://tinyurl.com/ScienceReason Science@ESA (Episode 7): Planetary science - Exploring our backyard, the Solar System (Part 2) In this seventh episode of the Science@ESA vodcast series Rebecca Barnes continues to journey through the wonders of modern astronomy bringing us closer to home as we begin to explore the Solar System. We'll discover the scale and structure of the Solar System, find out why we explore it and introduce the missions launched on a quest to further investigate our local celestial neighbourhood. --- Please subscribe to Science & Reason: • http://www.youtube.com/Best0fScience • http://www.youtube.com/ScienceMagazine • http://www.youtube.com/ScienceTV • http://www.youtube.com/FFreeThinker --- Planetary science is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science, but which now incorporates many disciplines, including planetary astronomy, planetary geology (together with geochemistry and geophysics), physical geography (geomorphology and cartography as applied to planets), atmospheric science, theoretical planetary science, and the study of extrasolar planets. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve a combination of space exploration, predominantly with robotic spacecraft missions using remote sensing, and comparative, experimental work in Earth-based laboratories. The theoretical component involves considerable computer simulation and mathematical modelling. Planetary scientists are generally located in the astronomy and physics or earth sciences departments of universities or research centres, though there are several purely planetary science institutes worldwide. There are several major conferences each year, and a wide range of peer-reviewed journals. • http://en.wikipedia.org/wiki/Planetary_science --- The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars. Beyond Mars is the asteroid belt - a region populated by millions of rocky objects. These are left-overs from the formation of the planets, 4.5 billion years ago. On the far side of the asteroid belt are the four gas giants - Jupiter, Saturn, Uranus and Neptune. These planets are much bigger than Earth, but very lightweight for their size. They are mostly made of hydrogen and helium. Until recently, the furthest known planet was an icy world called Pluto. However, Pluto is dwarfed by Earth's Moon and many astronomers think it is too small to be called a true planet. An object named Eris, which is at least as big as Pluto, was discovered very far from the Sun in 2005. More than 1,000 icy worlds such as Eris have been discovered beyond Pluto in recent years. These are called Kuiper Belt Objects. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as "dwarf planets". Even further out are the comets of the Oort Cloud. These are so far away that they are invisible in even the largest telescopes. Every so often one of these comets is disturbed and heads towards the Sun. It then becomes visible in the night sky. • http://sci.esa.int/science-e/www/area/index.cfm?fareaid=7 .

PREVIEW: Alien Planets & Eyeball Earths

Music by Zero Project. The hunt for planets beyond our solar system has reached a fever pitch. With some 500 planets revealed by ground telescopes, now, the ultimate planet finder, the Kepler space telescope, has released a tsunami of data. Among over a thousand new planet prospects are 200 multi-planet solar systems and 58 worlds in life-friendly orbits. They're all within a narrow window on the sky the size of your hand. That's why this may be the tip of the iceberg in a galaxy that's literally crawling with planets. Scientists are now beginning to envision what these worlds are like, with atmospheres, oceans, geological history. In the process, they are redefining what a planet might need to spawn life.

NASA/ESA SOHO & NASA SDO Comet Meets Sun, October 1, 2011

A comet discovered on Friday September 30, 2011 by an amateur astronomer disintegrated on Saturday October 1, 2011 when it plunged into the Sun. The Corongraph of NASA/ESA's SOHO captured the last few hours of the comet. Very shortly after the comet dove into the Sun a Coronal Mass Ejection (CME) exploded. As of current solar scientists do not believe that a comet can trigger a Coronal Mass Ejection - however, the question of if a comet could cause a magnetic instability on the Sun remains and is being studied. On July 6, 2011 the Solar Dynamics Observatory (SDO) observed a sungrazing comet and it appeared to interact with the plasma and magnetic field as it fell apart. The first two segments in this video are from October 1, 2011 and were observed by NASA/ESA's SOHO spacecraft. The last two segments were captured by NASA's SDO on July 5, 2011.

Big New ExoPlanet Haul

From EsoCast in 1080p, comes the announcement of a rash of new planet discoveries. Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular orbits within the habitable zone around its star. Among the new planets just announced by scientists, sixteen are super-Earths - rocky planets up to ten times as massive as Earth. This is the largest number of such planets ever announced at one time. A planet in orbit causes its star to regularly move backwards and forwards as seen from Earth. This creates a tiny shift of the star's spectrum that can be measured with an extremely sensitive spectrograph such as HARPS. In their quest to find a rocky planet that could harbor life, astronomers are now pushing HARPS even further. They have selected ten well-studied nearby stars similar to our Sun. Earlier observations showed that these were ideal stars to examine for even less massive planets. After two years of work, the team has found five light super-Earths around three of the stars. These planets are very good candidates for future observations looking for evidence of life. One of the newly found planets, named HD 85512 b, orbits inside the habitable zone. This is the narrow area around a star where water can exist in liquid form. Astronomers estimate that liquid water could possibly be present on this planet if it is a rocky world that has more than 50% cloud cover. By looking carefully at the results from the first 8 years of HARPS observations, the team has found that around 40% of stars similar to the Sun harbor at least one planet lighter than Saturn. These new results lead astronomers to believe that they could soon find more super-Earths in the habitable zones of their stars with HARPS. These planets will be great targets for powerful future telescopes to try to study their atmospheres looking for evidence of life. Thanks to HARPS, the search for another Earth elsewhere in the galaxy is picking up pace!
