NASA proposes steam-powered hopping robot for missions to the solar system’s icy moons

The video introduces Sparrow, a steam-powered hopping robot designed to explore icy terrains on Jupiter's moon Europa and Saturn's moon Enceladus. Sparrow features avionics, instruments, and thrusters within a spherical shell. It uses steam propulsion to hop over large distances, navigating Europa's icy surface. After collecting samples, Sparrow returns to the lander for collection.
