Social networking fuels collaboration among NASA researchers

Social networking isn’t rocket science, but the eggheads at NASA are showing how it can be used to help them pursue the most bleeding edge applications.

The space agency in May launches a new research network named NASA Earth Exchange (NEX), which combines high-end supercomputing resources with Earth system modeling and the decades of NASA’s remote sensing data to provide a new way of analyzing the planet’s climate and land use patterns.

According to a story at Supercomputing Online, NASA scientists think they can use the new network to slash the time needed to gather and analyze the massive, global-scale datasets they use -- from the months it takes now to just hours.

The key is the online collaboration will incorporate social networking, enabling NASA scientist and science teams scattered around the world to easily share datasets, algorithms, complex codes and research results.

They haven’t been able to do that before because it required physically transferring huge amounts of data to each other. With NEX, all of the data and codes will actually reside on the social networking platform so there will be no need for all of that laborious stuff.

Using NEX, the scientists will apparently be able to build custom project environments using virtualization technology that will automatically capture the entire analysis process. Those environments will also be reusable by other scientists who can add their own data to the remote sensing data, throwing open all kinds of new avenues for research into such things as urbanization, deforestation and biodiversity.

Details about NEX have been compiled into a wiki.

Separately, but as another example of how it is using the new Web technologies, NASA said it would start using semantic search to enable its employees to search through the more than 50 years of information it has collected on its space program.

It’s using software from United Kingdom-based Smartlogic, which in turn is using Google Search hardware.

Perhaps not surprisingly, Chris Kemp, the thought leader behind this and other IT efforts at NASA Ames, such as the Nebula cloud computing platform, has reportedly been bumped up to the new position of chief technology officer for IT at NASA headquarters.

The Army unfolds a roadmap for unmanned aircraft systems

It’s not usual for me, or anyone else that I know for that matter, to recommend a government document as a great piece of reading, but I’d stray from that norm and point to the U.S. Army Roadmap for UAS 2010-2035.

I’m not saying it’s great literature, and there’s sections of it that would serve well as a sleep aid, but for overall entertainment for the techie minded among you I think it makes the grade.

Turn first to a section that describes the far-term of the Army’s roadmap for its unmanned aircraft systems, which describes what the Army sees happening in the 2026-2035 timeframe. It talks there, among other things, about using bug-like nano UAVs to survey buildings before soldiers enter them, and use clouds of the critters operating as interlinked smart warfighting array of reconfigurable modules (SWARM) to do the same for area reconnaissance.

There’s lots of similar acronymic stuff in the document (this is the Army, after all), but most of it has a similar heft, particular that for both the far-term and mid-term (2016-2025) chapters.

Taken individually, none of the technologies will come as a surprise as they’ve been talked of before. But the roadmap provides a context for how they will work together, and it promotes a grand vision that’s pretty sweeping. Twenty years from now, battlefields and the skies over American itself could be filled with these flying robots.

There are provisos, of course, as there always is. The military overall wants as many unmanned aircraft as it can get it hands on, but the Government Accountability Office recently warned that the military’s ability to handle the number it already has is stretched. And then there’s a small matter about making sense of all of the data these things produce.

Pshaw! Don’t let these piddling matters interfere with the dream. Read the thing first. Reality can come later.

Cell-All smarter phone is DHS' version of the Tricorder

Remember the tricorder, that ubiquitous, do-everything handheld tool featured in the Star Trek TV program? Take a handheld computer, wave it around in front of a person to diagnose illnesses, or hold it up in the air during  field mission to detect chemical elements or energy sources. That device was one of the best examples of the ingenuity of science fiction.

Now, in a case of life imitating art, Star Trek science fiction is rapidly turning into science fact,  and it seems that  government agencies are at the leading edge of the research and development.

We’ve already pointed to the interest that the military has in developing Apple iPhone-like applications for its warfighters. Nothing specific right now other than it wants to investigate how the Army can enhance the iPhone; given the past history of wartime innovations we should expect some eye-popping innovations from  soon.

Now comes the news that the Homeland Security Department (DHS) is developing something it’s calling Cell-All, which will marry a smartphone with sensors capable of sniffing the air around it so it can isolate toxic chemicals. There are obvious uses for emergency responders, but also for military and other personnel looking for things as such hidden explosives.

DHS is looking to the telecommunications side of smartphones to help it develop linked sensors that could cast a broad and sensitive net of sniffers.

What these advances are taking advantage of is the acceleration in development of ever smaller, cheaper and more specialized chips along with faster and denser memory technologies.

Predictions just last year were that it could take 15 years for such things as wireless health sensors to appear, but you have it wonder what the projections will be at the end of 2010. The DHS, for example, is looking to have prototypes of its Cell-All device in a year.
