Mars' Molten Past
Houston TX (SPX) Nov 22, 2007Mars was covered in an ocean of molten rock for about 100 million years after the planet formed, researchers from the Lunar and Planetary Institute in Houston, Texas, UC Davis, and NASA's Johnson Space Center have found. The work is published in the journal Nature on Nov. 22. The formation of the solar system can be dated quite accurately to 4,567,000,000 years ago, said Qing-Zhu Yin, assistant ... more Study Sheds New Light On Early Formation Of Earth And Mars 
Houston TX (SPX) Nov 22, 2007A team of scientists from NASA's Johnson Space Center (JSC) and the Lunar and Planetary Institute (LPI), both in Houston, and the University of California, Davis (UCD) has found that terrestrial planets such as the Earth and Mars may have remained molten in their early histories for tens of millions of years. The findings indicate that the two planets cooled slower than scientists thought and a ... more China aiming to replace foreign satellites: report 
Beijing (AFP) Nov 19, 2007China is aiming to replace all its imported communications and broadcast satellites with home-made ones by 2010 as part of efforts to reduce its reliance on overseas technology, state media said Monday. The nation will step up research and development of these satellites as just one out of the 12 currently in use is Chinese-made, Sun Laiyan, chief of the China National Space Administration, ... more Mars Express Creates First Global Map Of Martian Ionosphere 
Paris, France (ESA) Nov 19, 2007With ESA's Mars Express, scientists continue to gain new insight into the mysterious Martian environment. Some of the most exciting results are being sent back by the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) experiment. MARSIS transmits low frequency radio waves towards the planet's surface and records the echoes of the different layers. Although Mars is sometim ... more Planets Forming In Pleiades Star Cluster 
Los Angeles CA (SPX) Nov 16, 2007Rocky terrestrial planets, perhaps like Earth, Mars or Venus, appear to be forming or to have recently formed around a star in the Pleiades ("seven sisters") star cluster, the result of "monster collisions" of planets or planetary embryos. Astronomers using the Gemini Observatory in Hawaii and the Spitzer Space Telescope report their findings in an upcoming issue of the Astrophysical Journal, th ... more |

Pasadena CA (SPX) Nov 14, 2007Spirit has been gradually losing power, with energy levels dropping to 320 watt-hours per Martian day (100 watt-hours is the amount of energy needed to light a 100-watt bulb for one hour). Measurements of atmospheric dust, known as Tau, have been averaging 0.65. That dust level is typical of levels measuring throughout most of the mission, but power levels are lower than in previous years becaus ... more The Appeal Of Mars 
Moscow (RIA Novosti) Nov 12, 2007Despite the numerous technical and medical-biological problems it would face, a manned mission to Mars is being spoken about with more and more certainty. Yet it is unclear why we should take such great risks to land astronauts on the Red Planet. Nor do we know whether the huge costs of such an expedition would ever be recouped. Yury Semyonov, a member of the Russian Academy of Sciences an ... more China to accept private funding for lunar missions 
Beijing (AFP) Nov 8, 2007China will accept private investment to help put a man and a rover on the moon, seeking outside funding for its expanding space ambitions, state media said Thursday. The funding opportunities will be open to "competent institutions and enterprises," the Shanghai Daily quoted a spokesman for the China National Space Administration as saying. "They could include scientific research organs, ... more NASA pressed to avert catastrophic Deep Impact 
Washington (AFP) Nov 8, 2007NASA penny-pinching risks exposing humankind to a planetary catastrophe if a big enough asteroid evades detection and slams into Earth, US lawmakers warned Thursday. But the US space agency said the chances of a new "Near-Earth Object" (NEO) like the one that wiped out the dinosaurs were too remote to divert scarce resources. Scott Pace, head of program analysis and evaluation at NASA, s ... more |

Washington (AFP) Nov 5, 2007The US shuttle Discovery undocked from the International Space Station on Monday, wrapping up a complex mission marked by a daring spacewalk to repair a torn solar array. After saying goodbye to their space station colleagues and closing the hatches, Discovery crew members smoothly sailed away from the ISS at 5:32 am (1030 GMT) before a scheduled landing set for Wednesday at 1802 GMT in Flor ... more Opportunity Studies Rock Composition And Changes In Atmosphere 
Pasadena CA (SPX) Nov 06, 2007Though atmospheric dust has returned to nearly pre-dust storm levels, Opportunity's solar arrays are still dustier than before the storm, keeping power levels about 200 watt-hours lower than pre-storm levels. Opportunity continues to generate solar power levels of more than 600 watt-hours per Martian day, or sol (100 watt-hours is the amount of energy required to light a 100-watt bulb for one h ... more Spirit To Head North For The Winter 
Pasadena CA (SPX) Nov 05, 2007With Martian winter approaching, the science and engineering teams have been hard pressed to select a site where Spirit can spend the winter. After previously narrowing the list of candidates to two sites, Spirit's handlers decided to send the rover to the northern edge of the elevated plateau known as "Home Plate," which Spirit has been exploring for many months now. ... more Embry-Riddle And Zero Gravity To Collaborate On Weightless Flights 
Daytona Beach FL (SPX) Nov 05, 2007Researchers, teachers and students will have access to weightless and variable-gravity conditions under a new agreement between Embry-Riddle Aeronautical University and Zero Gravity Corp. (Zero-G). Embry-Riddle and Zero-G will work together to integrate weightless flights and space science workshops for K-12 teachers, develop experiment programs for high school and college students, and expand m ... more
