Phoenix Set To Bake Some Ice-Rich Samples This Week![]() The next sample delivered to NASA's Phoenix Mars Lander's Thermal and Evolved-Gas Analyzer (TEGA) will be ice-rich. A team of engineers and scientists assembled to assess TEGA after a short circuit was discovered in the instrument has concluded that another short circuit could occur when the oven is used again. "Since there is no way to assess the probability of another short circuit occur ... more Canadian Asteroid-Hunting Satellite A World First ![]() Canada is building the world's first space telescope designed to detect and track asteroids as well as satellites. Called NEOSSat (Near Earth Object Surveillance Satellite), this spacecraft will provide a significant improvement in surveillance of asteroids that pose a collision hazard with Earth and innovative technologies for tracking satellites in orbit high above our planet. Weighing i ... more NASA Plans To Test Space Shuttle Replacement In Spring 2009 ![]() NASA is planning to conduct in spring 2009 the first test flight of a new carrier rocket with an advanced launch vehicle to replace the outdated space shuttle, the U.S. space agency said in a statement. "NASA is developing new spacecraft, the Ares rockets and Orion crew capsule, to deliver astronauts to the International Space Station (ISS) and send them on their way to the Moon," the stat ... more Exploding Asteroid Theory Strengthened By New Evidence ![]() Geological evidence found in Ohio and Indiana in recent weeks is strengthening the case to attribute what happened 12,900 years ago in North America - when the end of the last Ice Age unexpectedly turned into a phase of extinction for animals and humans - to a cataclysmic comet or asteroid explosion over top of Canada. A comet/asteroid theory advanced by Arizona-based geophysicist Allen We ... more Will We Ever Reach Mars ![]() The title of this article could be continued: Will we be able to come back? It may take years to find an answer, but the search has already been launched. During the next month, the Institute of Bio-Medical Problems will conduct a medical experiment to develop non-surgical methods of treatment for diseases that cosmonauts may develop during a long journey to Mars. Hardly anything can ... more |

![]() ![]() Now using an ion thruster that had been powered off since October, Dawn continues to make steady progress on its journey deeper into space. In this phase of the mission, each day of thrusting changes the probe's speed by 6.7 meters/second (15 miles/hour). Dawn will operate its ion thrusters for a total of more than 5 years, providing the extraordinary boost required to orbit both main belt ... more DigitalGlobe Releases CitySphere 2 For Worldwide Image Coverage ![]() Satellite imagery provider DigitalGlobe has released CitySphere 2.0, an enhanced version of its extensive library of on-demand digital satellite imagery of the most populated global cities. CitySphere 2.0 features the addition of dozens of never-before-available views of global cosmopolitan cities such as Dubai, Seoul and Jakarta, plus city images from less developed geographic regions acr ... more Rosetta Awakes From Hibernation For Asteroid Encounter ![]() Spacecraft controllers have just awoken Rosetta from hibernation to prepare for its encounter with asteroid (2867) Steins on 5 September. ESA's comet chaser will study the relatively rare asteroid as it flies by on its way to comet 67/P Churyumov-Gerasimenko. Launched in March 2004, Rosetta will reach its final destination only in 2014, after travelling a total of about 6500 million km. Th ... more NASA Reveals New Discoveries From Mercury ![]() Scientists have argued about the origins of Mercury's smooth plains and the source of its magnetic field for more than 30 years. Now, analyses of data from the January 2008 flyby of the planet by the Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft have shown that volcanoes were involved in plains formation and suggest that its magnetic field is actively produc ... more Astrium Concludes Galileo In-Orbit Test ![]() During approximately two months of in-space testing, known as the In-Orbit Test (IOT) phase, the Giove-B navigation satellite has performed excellently. Engineers from Astrium, the prime contractor for Giove-B, presented the results of the tests at the European Space Research and Technology Centre ESTEC in Noordwijk, Holland. The key components of the Galileo system, particularly the new ... more |
