00:00These robots may change the future of space exploration.
00:04Space Hopper is built to hop around low-gravity environments like asteroids and moons.
00:09During each jump, it adjusts its legs mid-air to land upright every time.
00:14In places where classic wheeled robots can't go, this little jumper could help search for signs of life.
00:21ReachBot is a climbing robot made to explore caves on Mars and the Moon.
00:25It uses long, extendable arms with grippers to grab cave walls and pull itself deeper inside.
00:32It's still in the prototype stage, but one day it could explore places no robot or human has ever reached.
00:39Spirit is a robot dog being trained to explore the Moon.
00:44To move over rocks, sand, and snow, it senses the ground and adjusts its steps like a real animal.
00:50Unlike wheeled rovers, it can handle steep slopes and loose, icy soil,
00:55perfect for exploring the Moon's still largely unexplored South Pole.
