Irvine, Calif., Nov. 4, 2010 -- UC Irvine astronomers, along with scientists across the globe, are discovering hundreds of new galaxies through brighter galaxies in front of them that deflect their faint light back to the massive Herschel telescope...
The ocean surface is 30 percent more acidic today than it was in 1800, much of that increase occurring in the last 50 years - a rising trend that could both harm coral reefs and profoundly impact tiny shelled plankton at the base of the ocean food...
Water ice on asteroids may be more common than expected, according to a new study that will be presented today at the world's largest gathering of planetary scientists. Two teams of researchers who made national headlines in April for showing ...
The European Space Agency and its 16 national delegations have come together with the European Commission and more than a hundred separate industries to develop future road maps for space technology research and development across the continent. The new 'European Space Technology Master Plan' consolidates the overall process for space R&D and highlights 20 separate harmonised technology areas. It was discussed at a round table at this year's Le Bourget with key representatives from the EC, European industry and ESA.
"When blind people take a taxi, they will be able to give directions to the taxi driver!" says Jose Luis Fernandez Coya. The man speaking really knows what he is talking about: he is blind but also heads the R&D department of ONCE, the National Organization of Spanish Blind people. This association has always been looking for helpful innovations and has just developed a system based on GPS to guide blind people. The system called "Tormes", named after a famous Spanish 16th century story, is a computer with a Braille keyboard and satellite navigation technology that gives verbal directions. This personal navigator was presented to the press in Madrid recently. The European Space Agency (ESA) was involved in this event because ONCE and ESA are already working on how to improve "Tormes."
The Columbia Accident Investigation Board (CAIB) continues their work into the investigation of the accident and a number of hearings are now being held in public. The chairman of the NASA Columbia Task Force (the body that supports the CAIB) gave a detailed briefing a few days ago to ESA and the other International Partners on the status to date. Over 40,000 lbs of debris have been recovered, representing 20% of the total Shuttle mass. However, nothing has yet been recovered west of Texas despite the fact that there is filmed evidence that debris had fallen over California. The search for debris in this area still continues. The Orbiter Experiments Recorder is the latest piece of important equipment to be found. This is a magnetic tape recorder that records data from various sensors during ascent and re-entry, which had not been tele-metered down to the ground. The recorder is currently at the Kennedy Space Centre and undergoing analyses.
Using the Hubble Space Telescope, astronomers have, for the first time, observed the atmosphere of an extrasolar planet evaporating into space. Much of this planet may eventually disappear, leaving only a dense core. It is a type of extrasolar planet known as a 'hot Jupiter'. These giant gaseous planets orbit their stars very closely, drawn to them like moths to a flame. The scorched planet called HD 209458b orbits 'only' 7 million kilometres from its yellow Sun-like star. By comparison, Jupiter, the closest gas giant in our Solar System, orbits 780 million kilometres from our Sun. NASA/ESA Hubble Space telescope observations reveal a hot and puffed-up evaporating hydrogen atmosphere surrounding the planet. This huge envelope of hydrogen resembles a comet with a tail trailing behind the planet. Earth also has an extended atmosphere of escaping hydrogen gas, but the loss rate is much lower.
The inauguration ceremony for the European Space Agency's first deep space ground station was held today in New Norcia, 150km north of Perth. The completion of the New Norcia facility, its first deep space ground station, is an important event for ESA. The station will play a major role in the Agency's deep space missions, including Rosetta and Mars Express, the latter expected to launch in May this year. The key component of the ground station is its massive antenna which weighs over 600 tonnes and is over 40 metres high. It can move 540 tonnes of ballast, cantilever and 35 metre dish while maintaining precision accuracy of its beam.
It is midnight on 1 January 2004 and you want to send a greeting on your mobile phone to a friend. Sorry, the line is too busy, try again later. If you think you are alone with this problem, you are wrong. Space agencies have had to work out ingenious solutions to prevent similar 'engaged, call later' tones from happening on Mars. For the first time, there will be seven spacecraft on the Red Planet at the same time. Will they all be able to 'phone home'?
In the late afternoon of Friday 31 January, a final trim manoeuvre nudged the Artemis satellite into its assigned position in geostationary orbit, completing a most remarkable satellite recovery operation which has lasted 18 months.
