NASA is working to send swarms of swimming robots into space

Nasa recently announced US$600,000 (£495,000) in funding for a study into the feasibility of sending swarms of miniature swimming robots (known as independent micro-swimmers) out to explore the oceans beneath shells icebergs of the many “ocean worlds” of our solar system. But don’t imagine metallic humanoids swimming underwater like frogs. These will probably be simple, triangular corners.

Pluto is an example of a probable ocean world. But the worlds whose oceans are closest to the surface, making them the most accessible, are Europa, a moon of Jupiter, and Enceladus, a moon of Saturn.
