Scientists Find New Unfamiliar Terrain on Mars
Mars Clouds Drier Than Thought
Galileo Funding Solution Remains Elusive
Decisions at the European Union's executive commission and among EU governments in the coming weeks will determine whether any kind of Galileo network - with or without the special features that had set it apart from GPS - will be built.
Attending a meeting here organized by the French IFRI foreign-affairs institute, officials noted that Galileo's expected in-service date has been pushed back by one year every year since the program was approved in 2001. Originally foreseen as operational in 2008, Galileo will not be completed until 2013 at the earliest, officials said - and only then if decisions on its financing are made in the coming months.

Star Of Eve is Mars
On Dec. 24, Mars reaches opposition. This means that it will appear as a bright orange star in the east soon after sunset. The Planet Watch feature on the daily Seattle Times Weather Page can help you determine its location.
The Geminid meteor shower peaks this Thursday-Friday, so if we have clear skies and you can get away from the city lights you should be treated to one of the best meteor displays of the year. Bundle up, get comfortable and face east as soon as the moon sets. Our other December target is the open cluster of stars called the Pleiades. They are among the most noted stars of history, poetry and mythology. Native American legend described them as seven lost children/
Christmas Eve Star will be Mars
The Geminid meteor shower peaks this Thursday-Friday, so if we have clear skies and you can get away from the city lights you should be treated to one of the best meteor displays of the year. Bundle up, get comfortable and face east as soon as the moon sets.
Our other December target is the open cluster of stars called the Pleiades. They are among the most noted stars of history, poetry and mythology. Native American legend described them as seven lost children. They are mentioned in the Bible, and included in ancient cave paintings in France. As soon as the sun sets, find them high in the eastern sky. By about midnight they will be high in the southern sky. To the naked eye they appear to be five to seven tightly packed blue stars. The group is made up of more than 1,000 individual stars that were born about 100 million years ago and are drifting through space. The bright blue stars are young hot stars that will burn out over the next few million years.

Opportunity investigates Smith2
Opportunity performed diagnostic tests of the shoulder joint that controls side-to-side movement of the robotic arm, known as Joint 1. The joint had stalled on Nov 22, 2007, while the rover waas taking measurements with the microscopic imager.
Working with NASA's Reconnaissance Orbiter, Opportunity successfully tested UHF radio transmissions in support of entry, descent, landing, and surface operations of the Phoenix mission, now en route to the red planet.
Mineral discovery explains Mars' landscape
Twin rovers defy death to continue exploring Mars
With the brutal Martian winter quickly approaching, Spirit faced almost certain doom if it couldn't get free and find a safe haven.
At NASA's Jet Propulsion Laboratory near Pasadena, mission manager John Callas was noticeably worried.
"For Spirit, this could very well be the worst situation she has ever experienced," he said with the tone of a worried father.
Then, after several days of erratically moving mere inches, the rover broke free of Tartarus on Nov. 28 and started rolling feebly toward a protective rocky area known as Winter Haven 3
Campaigns Should Support Space Exploration
"Space exploration brings enormous national security, economic and scientific benefits to our nation and should be a win-win issue for all the candidates to endorse," Aerospace Industries Association President and CEO Marion Blakey said.
Over the last two weeks Constellation has emerged as a campaign issue after suggestions by candidates from both parties that the program could be delayed. Other candidates immediately countered with their strong support of the program.

Clothing Technology Advances
While its funding is coming from the Defence Capability and Technology Demonstrator, the new lines of advanced clothing may one day also be adapted for use in space. CSIRO’s Flexible Integrated Energy Device (FIED) just received $4.4 million to research and develop their idea to have battery operated clothing. The clothing would include three components, "advanced, conductive fabrics as part of the battery, vibration energy harvesting device and a rectifier/power management system to power soldiers’ electronic equipment." Right now the concept is being adapted for use by soldiers to help to eliminate carrying large batteries around, but who knows what the future could hold for this type of technology.

NASA Study Reveals Less H20 in Clouds
New NASA laboratory measurements of simulated martian clouds reveal that scientists may have been overestimating the amount of water in the planet's atmosphere. "The martian clouds we are studying are composed of water ice, like some clouds on Earth. However, they are forming at very cold temperatures, often below minus 100 degrees Celsius (minus 212 degrees Fahrenheit)," said Tony Colaprete, a planetary scientist at NASA's Ames Research Center, Moffett Field, Calif. "What we have found in our laboratory studies is that it is much harder to initiate cloud formation at these cloud temperatures than what we thought," he explained.

NASA Delaying Space Shuttle Launch Until at least Saturday
According to the release, "two of the four engine cutoff...sensors inside the liquid hydrogen section of the tank failed a routine prelaunch check." In addition, other sensors also gave false readings, "indicating that the (fuel) tank was 'wet' when it was dry."
As of now, NASA said it is aiming for a launch that could happen as early as 12:43 p.m. EST Saturday. But given the importance of safety and of ensuring that the shuttle launch without problems, don't be surprised if there are additional delays.

NASA study says clouds on Mars contain less water
New NASA laboratory measurements of simulated martian clouds reveal that scientists may have been overestimating the amount of water in the planet's atmosphere.
The martian clouds we are studying are composed of water ice, like some clouds on Earth. However, they are forming at very cold temperatures, often below minus 100 degrees Celsius (minus 212 degrees Fahrenheit)," said Tony Colaprete, a planetary scientist at NASA's Ames Research Center, Moffett Field, Calif. "What we have found in our laboratory studies is that it is much harder to initiate cloud formation at these cloud temperatures than what we thought," he explained
"This difficulty results in larger cloud particles, which fall out of the atmosphere more quickly and, thus, result in less cloud mass and a drier atmosphere," Colaprete explained
A$4.4 million for clever clothing
CSIRO has just received funding of A$4.4 million to help bring this possibility a step closer.
CSIRO’s Flexible Integrated Energy Device (FIED) was one of eight proposals selected as part of the latest round of Defence Capability and Technology Demonstrator (CTD) Program funding announced last night.
Principal Research Scientist with CSIRO’s Energy Technology Division, Dr Adam Best, said it was envisaged that the technology would be incorporated into a piece of clothing and would comprise three components: advanced, conductive fabrics as part of the battery, vibration energy harvesting device and a rectifier/power management system to power soldiers’ electronic equipment.

Galactic Germs
Experiments show that a germ causing food poisoning and other illnesses can be three times more dangerous in space than on the ground. This only adds to the endless list of risks that astronauts need to be aware with when possibly going on a manned mission to mars or even the moon. The study also shows that the immune system weakens during longs trips in space. That means your bodies immune system would definitely be susceptible on a mission to Mars. So the lesson to be learned here: our future astronauts to Mars better have strong immune systems otherwise who knows how ill they could become

NASA Takes Swift Action after Report of Astronaut Drinking
The panel said certification of astronauts for flight duty has no method to detect drinking episodes.
It also recommended NASA develop a code of conduct for astronauts.
"In general, astronauts are highly motivated to fly," the report stated. "Opportunities to fly in space are scarce and decreasing. The criteria for flight selection and how they are applied are unknown to the astronauts. Medical and behavioral health issues are perceived as having high potential for use to eliminate astronauts from mission assignment."
China to launch Mars probe in 2009
Yinghuo-1 would reach the pre-set circling orbit and beam the first images of the red planet in September 2010, the state-run China Daily said, quoting a senior scientist.

Spirit still has a chance
As the crow flies, that spot is 240.5 meters (130.8 feet) away. During the next few weeks, Spirit's journey to "Winter Haven 3" is expected to be no less difficult, requiring the rover to maneuver across a sandy, rocky valley along the western edge of "Home Plate."
During Spirit's 14 Martian days in Tartarus, the rover's trials were reminiscent of those of the previous Martian winter, when Spirit spent 12 sols churning up white material in a sandy area while trying to reach the slopes of "McCool Hill."

The device will be used to store and provide energy over a continuous period of time and can be charged by plugging into an electrical power point or through vibration energy harvesting. This could eventually be used in outer space. I thinks it’s a great idea that could really help out astronauts.

China's First Mars Probe to Blast Off in 2009

LEGOS!
Comet's 'dust bunnies' to shower Earth
"The Geminids is really a hot meteor shower," Pitts said. The meteors fall at medium speed, so they're easy to locate, he added.
The Geminids can be seen from anywhere in the Northern Hemisphere, though you'll want to get away from city lights if possible. In truly dark skies, you may be able to see 60 to 120 meteors per hour.
Meteor showers come from comets, concoctions of carbon dioxide, rocks and dirt. A comet eventually warms up in its orbit around the sun and then discards its "dust bunnies," as Pitts called them. Earth cuts through that path and, as the comet dust falls into the heavier atmosphere nearer Earth, the meteors begin to glow.
