Description This artist’s concept depicts NASA’s three SkyFall Mars helicopters collecting data while flying over the surface of the Red Planet. The green frequency waves emanating from the helicopters’ large antennas depict collection of subsurface radar data. The red beams depict collect near-infrared imagery data from regolith (crushed rock and dust) and other surface features. […]
