Why NASA Should Bomb the Moon to Find Water: Analysis

From Popular Mechanics:

The Lunar Crater Observation and Sensing Satellite (LCROSS) is now traveling to the moon at 5592 mph and will crash-land on Oct. 9 in order to gather data from the 6-mile-high impact cloud it will create. Today, as NASA announced the crater where LCROSS will land (Cabeus-A), the mission continues to drum up controversy. Is crash-landing on the moon really necessary for science? Will it be worth the damage done to the moon? To both these questions, PM answers a resounding, Yes. Here's why we're rooting for NASA's October mission to bombard the moon.

From Popular Science:

Nanotechnology, lasers, genetics, and cancer? If there was also something about space, this story might have been a PopSci full house. Scientists at the University of California, Santa Barbara (UCSB), have figured out a way to deliver cancer-stopping RNA directly into the nucleus of a diseased cell. To get into the nucleus, the RNA is wrapped in special gold nanoshells which are then selectively opened by a laser.

Keeping Google Out Of libraries

From The BBC:

The proposed settlement between Google and US publishers must be resisted, argues Bill Thompson

Google is in the middle of a massive project to scan and digitise every book it can get its hands on, whether old or new, and if it gets its way then the US courts will soon endorse an agreement between the search engine giant and the US book industry that will allow it to do this without fear of prosecution for copyright infringement.

Authors and publishers will get some money in return, and we will all benefit from the improved access to digitised books that Google will provide.

From The Telegraph:

Having an attractive mate on your arm makes you look more attractive in the eyes of the opposite sex, claim scientists in research that could explain the continuing appeal of Hugh Hefner.

However going out with a better looking friend of the same sex can have the opposite effect.

Researchers have found that we bask in the reflective glory of our more attractive partners because others assume we must have hidden talents away from our looks.

Amazing Pictures: Space Shuttle Discovery Soars Through The Clouds Before Landing Safely (After A 2,000 Mile Diversion)

The space shuttle Discovery, lands on runway 22 at
Edwards Air Force Base near Rosamond, California.

From the Daily Mail:

The space shuttle Discovery landed safely in California early today after bad weather forced a switch of its touchdown site at the end of a two-week mission to the International Space Station.

NASA diverted the spaceship to Edwards Air Force Base in California's Mojave Desert after waiting in vain for two days for rain and clouds to clear over the shuttle's home port in Florida, the originally scheduled landing location.

Under partly cloudy desert skies, the shuttle landed at 0053 GMT.

White Dwarf "Close" To Exploding As Supernova

From Universe Today:

ESA’s XMM-Newton orbiting X-ray telescope has uncovered the first close-up of a white dwarf star that could explode into a type Ia supernova within a few million years. That's relatively soon in cosmic time frames, and although this white dwarf that is orbiting its companion star HD 49798, is far enough away to pose no danger to Earth, it is close enough to become an extraordinarily spectacular celestial sight. Calculations suggest that it will blaze initially with the intensity of the full Moon and be so bright that it will be seen in the daytime sky with the naked eye. But don't worry, it will be awhile!

Wolff (Space Science Inst.), Hubble Heritage Team (STScI / AURA), NASA

From Live Science:

Maybe even more than average citizens, the world's space agencies rely on daily and seasonal reports to better understand weather on Earth and other planets. Space-mission success ties directly to effective anticipation and navigation of inclement surface and atmospheric conditions.

Mission-design engineers at NASA, the European Space Agency (ESA), and similar organizations need to know what environmental issues a Mars Lander or Rover might face to ensure that heat shields, parachutes and other on-board mechanisms survive the trip through the atmosphere to the surface.

The Coming Battle Over Fresh Water

Hustle and Flow -- Audubon Magazine

As water becomes increasingly scarce, we may have to charge for every drop.

In a now-famous interview with The New York Times in 1995, Ismail Serageldin, the World Bank’s vice president for environmentally sustainable development, said, “Many of the wars in this century were about oil, but wars of the next century will be over water.” While the situation is currently considerably less dire in the United States than in many other places around the world, an escalating fight over water in the coming years is in the making. We are “entering an era of water reallocation, when water for new uses will come from existing users who have incentives to use less,” says Robert Glennon, the Morris K. Udall professor of law and public policy at the University of Arizona, in his new book Unquenchable: America’s Water Crisis and What to Do About It. Those reallocations can take place through contentious politicking and in the courts, or, Glennon argues, more peaceably, through market forces.

Why The DOJ Wants More On Yahoo Search Deal

From CNET:

The long road toward Microsoft and Yahoo's search deal could be set to get a little longer, or fall off a cliff.

Both companies have long expected the U.S. Department of Justice to scrutinize the deal to install Microsoft as the exclusive search provider for Yahoo's Web pages, which would also see Yahoo end its time as a search company. Microsoft and Yahoo confirmed Friday that the Justice Department has asked the two companies for more information about their deal, which is a step beyond taking a mere interest in the proceedings.

NASA Names Target For Water Hunt At Moon's South Pole

Scientists have suggested that water ice millions of years old might be found in the shadowed craters of the moon's north and south poles, where the sun never shines. (AP)

From L.A. Times:

The LCROSS satellite and rocket are to plunge into the surface Oct. 9, stirring up a dust cloud that may contain ice. The find would have major scientific implications and aid future space plans.

NASA scientists announced Friday that they had picked a 60-mile-wide crater near the moon's south pole as the place where they will send a rocket to punch a hole in the lunar surface next month in search of water.

Instruments aboard other satellites and on Earth have detected a significant amount of hydrogen, a telltale marker for water, on the northwest rim of the crater known as Cabeus A.

On the Scene: NASA's Huge Rocket Test

Ares First Stage Rocket Test: NASA, Walt Lindblom

From Space.com:

PROMONTORY, UTAH – After two previous cancellations of debut engine tests of NASA's new Ares I rocket, there was a bit of trepidation among the spectators near the ATK Space Systems test facility in Promontory Point, Utah.

On Thursday afternoon, ATK successfully test fired the Ares I rocket's first stage, a giant solid-fueled booster, that will be used to launch astronauts on NASA's Orion spacecraft no earlier than 2015. We were on location to witness the high tech fireworks show [SEE VIDEO], $75 million in the making. And while the price tag might be a bit daunting, the spectacle of the test-firing and the magnitude of the Ares project were truly breathtaking

Nanotubes Could Enable Self-Repairing Electronic Circuits

Nanotube Self-Healing Power: Capsules holding carbon nanotubes can put the zazz back in broken circuits J. Mat. Chem./RSC Publishing

From Popular Science:

Researchers develop nanotubes that can help circuits repair critical breaks.

Many people know the familiar wince when a cell phone or laptop hits the floor. But electronic devices of the future may self-repair tiny cracks or breaks in their circuitry with the help of nanotubes.

Researchers from the University of Illinois at Urbana-Champaign have created capsules that hold conductive nanotubes and can sit on circuit boards. Mechanical stress that causes a crack in the circuit would also split open some capsules and release the nanotubes to help bridge the gap.

From Live Science:

A dinosaur-killing asteroid may have wiped out much of life on Earth 65 million years ago, but now scientists have discovered how smaller organisms might have survived in the darkness following such a catastrophic impact.

Survival may have depended upon jack-of-all-trades organisms called mixotrophs that can consume organic matter in the absence of sunlight. That would have proved crucial during the long months of dust and debris blotting out the sun, when plenty of dead or dying organic matter filled the Earth's oceans and lakes.
