## Definition

a spacecraft designed to reach the surface of a planet or moon and stay there. Unlike a rover, it usually stays in one spot to collect data.

For teachers: a spacecraft designed to descend toward and come to rest on the surface of a celestial body. Typically distinguished from an orbiter or a rover by its stationary mission profile upon arrival.

## Examples

- The lander sent back clear photos of the rocky surface.
- Engineers lost contact with the lander shortly after it entered the thin Martian atmosphere.
- The mission's success depended on the lander's ability to deploy its scientific instruments autonomously in the extreme cold of the lunar south pole.

## Usage notes

- Often used in compound nouns such as 'lunar lander' or 'Mars lander'.
