NASA has just funded seven far-out space-exploration concepts, including a submarine that would explore the hydrocarbon seas of Saturn's huge moon Titan, an origami energy reflector and rapid space transit with an electric sail.
All of the proposals, including the one for the Titan submarine have been awarded funding under Phase II of the NASA Innovative Advanced Concepts program, or NIAC.
Phase II grants, which are worth up to $500,000, allow scientists to continue working on bold ideas that received Phase I NIAC funding. The grants are intended to encourage development of potentially transformative space technology and offer the resources to test the feasibility and intricacies of brand-new ideas.
