A futuristic space-exploration proposal from NASA would see shape-shifting robots roaming the surface or atmosphere of the soupy Saturn moon Titan, which may host a precursor to the chemistry of life.
The flying, amphibious robot, called Shapeshifter — one of 25 NASA-funded proposals — could be used to cruise through Titan's atmosphere, go spelunking in caves or dive into the moon's many seas.
"Shapeshifter can morph into a ball that rolls on the surface, a flight array that can fly and hover above-surface and move in subsurface voids, and a torpedo-like structure to swim under liquid efficiently, among other mobility modes," NASA officials wrote in a statement.

Shapeshifter is one of 25 early-stage technology proposals selected in the 2018 round of NASA's Innovative Advanced Concepts (NIAC) Phase 1 concepts. Other proposals include space telescope swarms and meteoroid impact detection. Each of the proposals is valued at approximately $125,000. Investigators have nine months to work on the definition and analysis of the concepts.
At the end of the process, the teams can apply for Phase 2 awards. These are valued at up to $500,000 for two years of study. This year's NIAC selection includes nine Phase 2 proposals, which range from interstellar precursor missions, to a huge space telescope, to an exploration concept for an icy Neptune moon called Triton.
In general, NIAC proposals are considered very early stage, years or decades away from a mission flight — if they remain of interest for long enough. But their work provides a library of concepts from which NASA can draw during mission development, the agency said.
"The NIAC program gives NASA the opportunity to explore visionary ideas that could transform future NASA missions by creating radically better or entirely new concepts while engaging America's innovators and entrepreneurs as partners in the journey," Jim Reuter, acting associate administrator of NASA's Space Technology Mission Directorate, said in the NASA statement. "The concepts can then be evaluated for potential inclusion into our early stage technology portfolio."
