Bonn, Germany (SPX) Aug 23, 2010
Erhard Diedrich, in charge of the building of the Inuvik satellite station, returned from Canada with his colleagues, a happy man. The inauguration on 10 August was not only moving, but also marked the end of a successful first checkout phase. Over 300 passes of data have been acquired since April this year, among them 60 from the TanDEM-X satellite. We acquired a first image over the Inuv

Activity At Sakurajima Volcano Intensifies (anglès) - Dm, 24/08/2010 - 12:10
Washington DC (SPX) Aug 23, 2010
By mid-August, Sakurajima Volcano-one of Japan's most active-had erupted ash at least once every week during 2010. On August 19, 2010, an ash plume was sighted at 9,000 feet (2,700 meters), according to the Tokyo Volcanic Ash Advisory Center. This natural-color satellite image shows the gray plume moving west (towards image top) from the volcano's summit. Simultaneously, a pyroclasti

Anaxagoras Crater

This image from the Lunar Reconnaissance Orbiter shows the floor of the moon's Anaxagoras crater, including a portion of the crater's anorthositic central uplift. The boulders perched on ridges are eroding out of densely fractured bedrock. This image was taken by the Lunar Reconnaissance Orbiter Camera, or LROC, which consists of a pair of narrow-angle cameras and a single wide-angle camera. The mission is expected to return over 70 terabytes of image data. Image Credit: NASA/GSFC/Arizona State University

Stanford Researchers Tapped To Help Make Rules For Commercial Space Travel (anglès) - Dll, 23/08/2010 - 10:10
Stanford CA (SPX) Aug 23, 2010
Space may be the final frontier, but it's going to get more crowded pretty soon. And Stanford researchers are working to make sure the new pioneers can get there safely and easily. Commercial communication satellites and government-backed space missions have been under way for decades. But private companies like Virgin Galactic are on the verge of putting ordinary people into space as tour

Senate 'space jobs' bill announced (anglès) - Dll, 23/08/2010 - 10:10
Washington (UPI) Aug 19, 2010
A U.S. senator has introduced legislation he says would give tax incentives to private companies and investors developing commercial spacecraft. Sen. Bill Nelson, D-Fla., says his measure, called the Commercial Space Jobs and Investment Act, would also create up to five regional business enterprise zones in the United States to attract commercial space ventures and create jobs in region

Space tourist launch plane damaged (anglès) - Dll, 23/08/2010 - 10:10
Mojave, Calif. (UPI) Aug 20, 2010
The mother ship jet designed to launch suborbital space tourist flights was damaged upon landing in California when a landing gear collapsed, officials said. Officials with Scaled Composites, the Mojave, Calif., company that built the twin-fuselage carrier plane, said a mechanical problem with the left main landing gear on the Virgin Galactic WhiteKnightTwo jet caused the "minor inciden

India To Host Mega Global Space Science Event (anglès) - Dll, 23/08/2010 - 10:10
Bangalore, India (PTI) Aug 23, 2010
About 3000 scientists from more than 50 countries are expected to participate in the 39th Scientific Assembly of Committee on Space Research (COSPAR), a mega science event, to be hosted by Indian Space Research Organisation, in Mysore during July 14-22, 2012. The International Council for Science founded COSPAR in 1958. Establishment of COSPAR coincided with the launch of the first artific

Japan plans second asteroid sample grab (anglès) - Dll, 23/08/2010 - 10:10
Tokyo (UPI) Aug 19, 2010
Japan will send another satellite on a mission to capture material from an asteroid and bring it back to Earth for study, scientists say. The Japan Aerospace Exploration Agency says a successor to the troubled Japanese spacecraft Hayabusa, which managed to return a capsule to Earth this year, could launch as early as 2104, reported Wednesday. The cost of the new spacecr

Martian 'mud' volcanoes eyed for life (anglès) - Dll, 23/08/2010 - 10:10
Washington (UPI) Aug 19, 2010
Researchers say if life existed on Mars, the best place to look today is a region rich in what they say were mud volcanoes spewing sediment from underground. An area of the planet's northern plains called Acidalia Planita contains thousands of the circular mounds, formed from ancient sediment that might contain evidence of possible past or present life, Astrobiology magazine reports.

Laser detector uses 'darkest' material (anglès) - Dll, 23/08/2010 - 10:10
Washington (UPI) Aug 18, 2010
U.S. researchers say they've used the world's darkest material - a forest of carbon nanotubes - to develop a sophisticated laser power detector. Scientists at the National Institute of Standards and Technology will use the ultra-dark detector to make precision laser power measurements for advanced technologies such as optical communications, laser-based manufacturing, solar energy con

Japan's Panasonic to boost plasma panel output in China (anglès) - Dll, 23/08/2010 - 10:10
Tokyo (AFP) Aug 20, 2010
Japanese electronics giant Panasonic said Friday it will boost its plasma panel production in Shanghai to meet growing demand for flatscreen televisions in China. The Chinese unit, Panasonic Plasma Display (Shanghai) Ltd (PPDS), produces 25,000 42-inch panels a month and will start up a new plant in April 2012 with a monthly capacity for 120,000 42-inch panels, Panasonic said.

ISS orbit corrected (anglès) - Dll, 23/08/2010 - 10:10
Moscow (AFP) Aug 19, 2010
The orbit of the International Space Station (ISS) was successfully corrected on Thursday, an official of the Russian space flights control centre announced. The orbit was raised by 2.2 kilometres to 355.5 kilometres (220.9 miles), the official said, quoted by Interfax news agency. The manoeuvre was carried out using the engines of the Russian cargo vessel Progress M-06M. The orbital

Pasadena CA (JPL) Aug 23, 2010
Opportunity again drove five times in the past week, adding more to the total rover odometry as she makes her way to Endeavour crater. The rover drove on Sols 2329, 2330, 2333, 2334 and 2335 (Aug. 12, 13, 16, 17 and 18), totaling over 330 meters (1,083 feet). The rover has been driving with long (about 70 meter, or 230 foot) commanded drives followed by short drive segments of autono

NASA To Announce Latest Findings By Kepler Spacecraft

NASA will hold a media teleconference Thursday, Aug. 26, at 1 p.m. EDT to discuss the Kepler spacecraft's latest discovery about an intriguing planetary system.

Bright Lights

Two extremely bright stars illuminate a greenish mist in this image from the Spitzer Space Telescope's "GLIMPSE360" survey. This mist is comprised of hydrogen and carbon compounds called polycyclic aromatic hydrocarbons (PAHs), which also are found here on Earth in sooty vehicle exhaust and on charred grills. In space, PAHs form in the dark clouds that give rise to stars. These molecules provide astronomers a way to visualize the peripheries of gas clouds and study their structures in great detail. They are not actually green; but are color coded in these images to allow scientists see their glow in infrared. This image is a combination of data from Spitzer and the Two-Micron All-Sky Survey (2MASS). The Spitzer data was taken after Spitzer's liquid coolant ran dry in May 2009, marking the beginning of its "warm" mission. Image Credit: NASA/JPL-Caltech/2MASS/SSI/University of Wisconsin

Mud Volcanoes On Mars (anglès) - Dv, 20/08/2010 - 17:10
Moffett Field CA (SPX) Aug 20, 2010
If life does - or did - exist on Mars, signs of such life might well be found in a region in the northern plains called Acidalia Planitia, according to a new study. The region appears to be dotted with what scientists believe are geological structures known as mud volcanoes, spewing out muddy sediments from underground. These sediments might contain organic materials that could be biosigna

NASA Sensors To Guide Spacecraft To Safe, Distant Landings (anglès) - Dv, 20/08/2010 - 17:10
Hampton VA (SPX) Aug 20, 2010
NASA is developing technologies that will allow landing vehicles to automatically identify and navigate to the location of a safe landing site while detecting landing hazards during the final descent to the surface. This is important because future missions - whether to the Moon, an asteroid, Mars or other location - will need this capability to land safely near specific resources that are

Cosmic Lens Used To Probe Dark Energy For First Time (anglès) - Dv, 20/08/2010 - 17:10
Pasadena CA (SPX) Aug 20, 2010
Astronomers have devised a new method for measuring perhaps the greatest puzzle of our universe - dark energy. This mysterious force, discovered in 1998, is pushing our universe apart at ever-increasing speeds. For the first time, astronomers using NASA's Hubble Space Telescope were able to take advantage of a giant magnifying lens in space - a massive cluster of galaxies - to narrow in on
