A lander is a spacecraft that descends towards, then comes to rest on the surface of an astronomical body other than Earth. [1] [page needed] In contrast to an impact probe, which makes a hard landing that damages or destroys the probe upon reaching the surface, a lander makes a soft landing after which the probe remains functional.
Rovers which land on celestial bodies far from the Earth, such as the Mars Exploration Rovers, cannot be remotely controlled in real-time since the speed at which radio signals travel is far too slow for real-time or near-real-time communication.
An artist's concept of the Athena lander on the moon, some 100 miles from the lunar south pole. A high tech drill can be seen by the left landing leg that will dig into the surface to measure ...
