Aircraft, spacecraft, or vehicles designed to land and descend to a surface; plural of lander.
From 'land' (Germanic origin) plus '-er' suffix meaning 'one who lands.' Modern usage especially for spacecraft developed with the space age.
Moon landers like the Apollo Lunar Module are engineering marvels—the Apollo landers weighed 17 tons yet fit inside a shaft smaller than an elevator, requiring impossible feats of engineering to bring astronauts to the Moon!
