Cutting Edge

JOHNSON SPACE CENTER, Houston--The United States and China have agreed to discuss expanded cooperation in space science and to start a "dialogue" on human space flight and exploration, according to a joint statement released in Beijing on Tuesday. The U.S.-China Joint Statement said both nations looked forward to reciprocal visits by the NASA administrator and appropriate Chinese space leaders in 2010.

"The United States and China look forward to expanding discussions on space science cooperation and starting a dialogue on human space flight and space exploration, based on the principles of transparency, reciprocity, and mutual benefit," the joint statement said. "Both sides welcome reciprocal visits of the NASA administrator and the appropriate Chinese counterpart in 2010."

John Logsdon, a space policy analyst at George Washington University, said expanded cooperation makes sense, but only if both sides are open with each other and share the technical data necessary to ensure safe operations.

"I think it's great," he said in a telephone interview. "It opens the door to see whether, in fact, there's a basis for cooperation. I think the operative word in there is 'transparency.' If China is willing to provide the information we need to work with them and vice versa--they were the ones who have been somewhat reticent to do that--I think it makes total sense."

The future direction of the U.S. manned space program is unclear as NASA waits for the Obama administration to make a decision on how the agency should proceed after the space shuttle is retired next year.… Read more

IBM researchers have cooked up a quick medical diagnostic testing system based on a silicon chip that can get by on a small sample and test for multiple diseases.

The breakthrough to be announced Tuesday means that physicians can test a patient immediately following a heart attack to improve survival rates. The test checks for disease markers, proteins that can be detected in blood using "capillary action force." In a nutshell, capillary forces refer to the tendency of a liquid to rise in narrow tubes or be drawn into a small opening.

The IBM Research-Zurich findings will be … Read more

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

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

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

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

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

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

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
