NASA Reviving its 'Blue Sky' Think Tank

NIAC has funded research into spacesuits that could be coated with proteins to generate electricity solely through the natural movement of the astronauts wearing them

NASA should revive its Institute for Advanced Concepts, a blue-skies idea mill that closed in 2007, says an expert panel – but it says the new incarnation should have its feet a little closer to the ground.

NASA's Institute for Advanced Concepts (NIAC) was founded in 1998 to harvest innovative ideas for spaceflight and aeronautics from outside the NASA community.

It received $4 million a year, about 0.02 per cent of NASA's annual budget, and funded more than 100 futuristic spaceflight and aeronautics projects that no one else would touch. The projects included motion-sensitive spacesuits that generate their own power, techniques to construct buildings in space using radio waves, and spherical robots to explore Mars, among many others.

But in 2007, a combination of budget constraints and internal politics shut the organisation down. On Friday, a committee convened by the US National Research Council released a report suggesting that NASA bring back the think tank.

The committee, which included a mix of people from academia and industry, found that NIAC had been successful right up until its final days. "They were definitely living up to their contract at the time they were terminated," says committee co-chair Robert Braun, a professor of space technology at the Georgia Institute of Technology.

Three NIAC-funded projects are now "on a path toward one day being a NASA mission", Braun says, including a prototype plasma rocket, an X-ray interferometer that is being considered for NASA's Black Hole Imager mission, and a "star shade", which could help existing space telescopes search for extrasolar planets.

Other projects have had unexpected medical spinoffs, like a skin-tight spacesuit that can help children with cerebral palsy walk. "By and large, the topics that they invested in were pushing the state of the art, were very advanced in terms of far-out thinking, and I'd say a decent percentage of them had the possibility of turning into something," Braun told New Scientist.
