The tiny Salto robot mimics the extraordinary leaping ability of the furry little galago by storing energy in its springs as it crouches. This stored power -- similar to that retained in the tendons of the galago between jumps -- is released suddenly to enable the Salto to execute successive leaps.

Molten regolith electrolysis, a method of extracting metals from soil to serve as the material for 3D printing, may be able to produce vital building materials for future Mars visitors. Researchers from NASA and the University of Central Florida are working on the concept as a way to reduce the massive amount of material that would otherwise need to be launched from Earth for a Mars mission.
