NASA Report Details Columbia Disaster
sea-maid submitted, created time 5 days 17 hours (www.time.com)
Seat restraints, pressure suits and helmets of the doomed crew of the space shuttle Columbia didn't work well, leading to "lethal trauma" as the out-of-control ship lost pressure and broke apart, killing all seven astronauts, a new NASA report says. At least one crew member was alive and pushing buttons for half a minute after a first loud alarm sounded, as he futilely tried to right Columbia during that disastrous day Feb. 1, 2003. 
Mystery stone circles may point to water on Mars

Using cameras on NASA's Mars Reconnaissance Orbiter, Matt Balme of the Open University in Milton Keynes, UK, and his colleagues mapped the Elysium Planitia, a region near the equator. They saw rings up to twenty-three meters across made up of stones sorted by size into concentric bands.
New window on the high-energy universe

New telescope finds that the high-energy share of gamma-ray bursts arrive at Earth significantly later than the low-energy portion.
Did lack of comet impacts help life evolve?

IT SEEMS we got off lightly in the cosmic lottery. Deadly comet impacts may be much rarer in our solar system than in others nearby.
First detection of carbon dioxide in an exoplanet

Moving one step closer to finding the fingerprints of life in a habitable planet beyond the solar system, astronomers have for the first time detected carbon dioxide in the atmosphere of a planet that orbits a star other than the sun.
The extrasolar planet and its star lie about sixty-three light-years from Earth. A gaseous body slightly bigger than Jupiter, the orb circles its parent star at a proximity that renders it far too hot to support life
Microbes drove Earth's mineral evolution

A comprehensive history of Earth's mineral wealth concludes that without life, many raw materials wouldn't exist. In the early interstellar medium, scientists say, there were about twelve minerals. The planetary formation process upped this to around sixty. The addition of water (itself a mineral) allows for more different kinds of reactions and the mineral count jumps into the hundreds
Astronautics: The Hubble Space Telescope Will Not Be Repaired Until Next Year

The Hubble Space Telescope seems to be its own worst enemy. The space shuttle Atlantis had been scheduled to tak en eleven-day trip to the Hubble to allow astronauts to replace old parts and make repairs, but the mission will have to be delayed until 2009--because the Hubble is broken.
NASA scientists have decided to permit the Hubble to switch to its backup Hubble Control Unit/Science Data Formatter and take the risk of this one breaking too, but it will allow the Hubble to resume its observations
Water's role in Martian chemistry becoming clearer

As its mission nears its end, the NASA Phoenix Mars Lander finds strong evidence for minerals similar to those formed on Earth by liquid water.
SpaceX 's Falcon 1 shows successful launch
Darkfrog submitted, created time 3 months 1 week (www.nature.com)
Private rocket company SpaceX has been in some trouble lately. However, the successful test of its new Falcon 1, which reached low earth orbit after it was launched late this past Sunday.
The Falcon 1 can only lift one ton of cargo. To compete, SpaceX will have to built a rockets that can lift at least ten tons. Even so, this is a huge triumph. SpaceX estimates that each launch will cost $10 million, about one-fourth the cost of current systems. With the American shuttle program winding down, this is a timely development.

The orbiting observatory has suddenly stopped transmitting data. NASA reports an unknown failure inside a data formatting unit as culprit.
NASA is debating whether to command Hubble to switch to a backup unit, which would require reconnecting all five scientific devices or to transport a new backup unit from Earth to the telescope. Considering that the current backup unit has been subject to eighteen years of crippling daily temperature changes, the earthbound backup may be the way to go.
Mars iron is ideal for building future bases
sea-maid submitted, created time 3 months 1 week (space.newscientist.com)
FUTURE colonizers of Mars needn't worry about lugging materials from Earth to build their bases - the most widely used building material on Earth, steel, could be manufactured on the Red Planet.
The rover Opportunity has found elemental iron - a key ingredient of steel - peppered across the Martian surface as a result of collisions with iron-rich meteorites. The dry conditions and lack of atmospheric oxygen mean that the stuff has not rusted, says Geoffrey Landis of NASA's Glenn Research Center in Cleveland, Ohio
Nature inverviews Senator Obama on science issues
Darkfrog submitted, created time 3 months 2 weeks (www.nature.com)
The title says it all. Obama, in his own words, responds to Nature magazine on scientific issues. The original idea for the article had been to get both candidates' views, but McCain's campaign declined Nature's invitation. Summaries of Senator McCain's views are given instead.
The only scientific issue for which McCain shows more enthusiasm than Obama is the space program. On others, he is either surpassed or matched by Obama
Politics: U.S. presidential candidates outline their positions on science issues
Darkfrog submitted, created time 3 months 3 weeks (www.nytimes.com)
Senator Obama focused more on the government's role in supporting basic research while Senator McCain favored tax breaks for private businesses, but both candidates claim to support education, defense, federal funding for embryonic stem cell research and space. The only thing this article lacks is enough detail to see where either or both men might be weaseling. Because--they're politicians--they're going to weasel.
It is starting to look like, for the American scientific community, either candidate would be an improvement over our current situation.

It's now or never for the Opportunity. The Mars rover Opportunity is set to climb out of the Victoria crater a bit ahead of schedule. The original plan had been to allow the rover more time to examine the layers of the Martian crust exposed in the crater's sides, but its operators noticed a spike in the current similar to the one that preceded severe problems with its sister rover, Spirit. If the Opportunity were to lose one of its six wheels now, say scientists, it would make it nearly impossible for it to climb out of the crater and visit other parts of the Martian surface.
Minimum Mass for Galaxies Discovered: Breakthrough Sheds Light on Mysterious Dark Matter

By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe – ten million times the mass of the sun.
