NASA’s New Mars Rover Is Ready for Space Lasers – Jet Propulsion Laboratory
Perseverance is one of a few Mars spacecraft carrying laser retroreflectors. The devices could provide new science and safer Mars landings in the future.
Perseverance is one of a few Mars spacecraft carrying laser retroreflectors. The devices could provide new science and safer Mars landings in the future.
When the Apollo astronauts landed on the Moon, they
brought devices with them called retroreflectors, which are essentially small
