Shuttle Atlantis takes off on station delivery mission

KENNEDY SPACE CENTER, Fla.--The space shuttle Atlantis roared to life and raced into orbit Monday on a critical mission to deliver 15 tons of equipment and spare parts to the International Space Station, gear needed to protect against failures after the shuttle fleet is retired next year.

The shuttle's three hydrogen-fueled main engines fired up at 120-millisecond intervals and six seconds later, after computers verified the powerplants were operating normally, Atlantis' twin solid-fuel boosters ignited with a flash at 2:28 p.m. EST, instantly pushing the orbiter skyward.

As commander Charles Hobaugh and pilot Barry "Butch" Wilmore monitored the computer-controlled ascent, Atlantis wheeled about its vertical axis and arced away to the northeast, into the plane of the space station's orbit in the first step of a complex two-day rendezvous.

The shuttle's boosters operated normally, separating from Atlantis' external fuel tank as planned two minutes and four seconds after liftoff, and the spaceplane continued toward its planned preliminary orbit on the power of its three main engines.

A television camera mounted on the side of Atlantis' external tank provided spectacular views as the shuttle thundered toward space, showing the Florida coastline and scattered clouds dropping away below as the ship accelerated toward space.… Read more

Hackers create tools for disaster relief

MOUNTAIN VIEW, Calif.--Google, Microsoft, and Yahoo may be tough competitors when it comes to Internet software and services, but they are putting their differences aside to build a developer community to tackle bigger picture problems like saving lives in emergencies.

The companies have joined with NASA, the World Bank, and PR agency SecondMuse to organize the first-ever Random Hacks of Kindness event, which was held at a warehouse space-cum community center called Hacker Dojo this weekend. For two days, coders worked on ways to use technology to help solve real-world problems, such as how people can get information and … Read more

NASA spacecraft confirms water ice deposits on moon

Making a bigger splash than expected, the crash of an empty rocket stage in a permanently shadowed crater near the moon's south pole last month kicked up a surprising amount of water ice and vapor, confirming the presence of a potentially valuable resource for future space travelers.

"I'm here today to tell you that indeed, yes, we found water," said Anthony Colaprete, the project scientist and principal investigator for the Lunar Crater Observation and Sensing Satellite. "And we didn't find just a little bit, we found a significant amount."

Holding up water jugs to make the point, he said "if you remember, a month ago we were talking about teaspoons going into glasses over football fields. Well, now I can say today that in the 20- to 30-meter (65- to 100-foot-wide) crater LCROSS made, we found maybe about a dozen of these two-gallon buckets worth of water."

And more than water. Data from the LCROSS instruments show signs of other compounds that may shed light on the moon's evolution.

"It's a whole lot more beyond the water," Colaprete said. "That's the exciting part in my mind, it's not only about the water now. There's actually a lot more here that we're going to be talking about in the months ahead, looking at the LCROSS data."

Said Greg Delory, a researcher at the University of California at Berkeley: "This is not your father's moon. Rather than a dead and unchanging world, it could in fact be a very dynamic and interesting one that could tell us unique things about the Earth-moon system and the early solar system."… Read more

Cough into your cell phone, not your sleeve

We've already written this week about using cell phone imaging to analyze a blood sample and diagnose disease. Because viruses such as influenza are smaller than light waves, diagnosing something like H1N1 is not yet possible.

Thankfully, the sounds of our coughs might be all we need to diagnose whether we have a cough, flu, or respiratory disease. It all boils down to the quality of a cough, such as whether it is dry or wet (aka "productive" or "unproductive"), where the presence or absence of mucus on the lungs helps to determine the cause … Read more

NASA hopes to free Mars rover from 'sand trap'

After months of tests and analysis, engineers plan to beam commands to NASA's Spirit Mars rover Monday, kicking off a long-awaited attempt to free the hardy craft from the talcum powder-like soil of a hidden crater that trapped it last April.

"Spirit's facing the most challenging situation it's seen yet on the surface of Mars," Doug McCuistion, director of NASA's Mars exploration program, said Thursday. "We know a lot of people around the world...view Spirit with great affection, exploring the Red Planet along with it, experiencing the excitement, seeing new and exciting … Read more

NASA launches Web resource for 2012 predictions

Over the past few weeks, we've heard more and more about 2012 when, according to some, the world will end. Responding to all that talk with a healthy dose of skepticism, scientists at the National Aeronautics and Space Administration have launched a Web page to dispel the myths surrounding the momentous occasion.

On an FAQ page called, "2012: Beginning of the End or Why the World Won't End?" NASA wrote that much like the Y2K scare a decade ago, the end of the world won't come in 2012.

"Impressive movie special effects aside, December … Read more

Remote-control gun turrets, made for Italy

The Italian army has ordered 81 Hitrole Light remote-controlled weapon stations for its Iveco Lince vehicles in response to increased attacks in Afghanistan employing improvised explosive devices, according to a statement last month from Italian Ministero della Difesa, or ministry of defense.

Italy has struggled to live up to its NATO commitments in the face of widespread domestic opposition to the war in Afghanistan, and it has gone to great lengths to keep casualties to an absolute minimum. One way to do that is to stay buttoned-up.

The Hitrole is an electrically powered machine gun turret, operated by a single … Read more

Sponge absorbs 180 times its weight (in toxic sludge)

That tiny, plastic-looking black cube up there can absorb up to 180 times its own weight in toxic waste without absorbing any water. How? As with just about every amazing and/or inexplicable scientific breakthrough nowadays, the answer is spelled N-A-N-O.

Researchers at Peking and Tsinghua universities, both in Beijing, have adapted carbon nanotubes into a sponge-like material that can be squeezed dry, which sounds like extremely exciting news for the infomercial cleaning product industry. One minor detail:

Since carbon nanotubes are hydrophobic, there's no modification required to make them not absorb water.

For the record, that includes mysteriously … Read more

New York hospital revives ailing computer network

It's no secret that the installed base of technology at large medical facilities needs refreshing, especially as hospitals work toward digitizing medical records.

At St. Vincent's Catholic Medical Center in New York, a nonprofit with 42 facilities across five boroughs, the constant accessing and updating of patient records through the hospital's shared-bandwidth MPLS network resulted in unacceptable lag time pretty much all day, every day.

So Kane Edupuganti, director of IT Operations & Communications, convinced the higher-ups to retire the hospitals' hundreds of five-plus-year-old desktops and buy more than 600 zero client cubes from Pano Logic.
