ATLAS instrument assembly at NASA GSFC. The sole instrument on ICESat-2 is the Advanced Topographic Laser Altimeter System (ATLAS), a space-based lidar.It was designed and built at Goddard Space Flight Center, with the laser generation and detection systems provided by Fibertek.
According to the NASA web page on the project, it will provide state-of-the-art automated descent and landing system for planetary lander craft. A surface-tracking sensor suite with real-time hazard avoidance capabilities will assess altitude and velocity of the descending vehicle and the topography of the landing site to permit precision landing.
The Lunar Orbiter Laser Altimeter investigation provides a precise global lunar topographic model and geodetic grid. Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) The Lunar Reconnaissance Orbiter Camera addresses the measurement requirements of landing site certification and polar illumination.

The sole instrument on ICESat was the Geoscience Laser Altimeter System (GLAS), a space-based lidar. GLAS combined a precision surface lidar with a sensitive dual-wavelength cloud and aerosol lidar. The GLAS lasers emit infrared and visible laser pulses at 1064- and 532-nm wavelengths.
As defined by NASA Technical Standard NASA-STD-7002A, [1] it refers to a strategy where no test-dedicated qualification article exists and all production (flight) hardware is intended for flight. An example of a program using protoflight methods is the Mars Orbiter Laser Altimeter project.

The Advanced Topographic Laser Altimeter System (ATLAS) on NASA's Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) is a photon-counting lidar that uses the return time of laser light pulses from the Earth's surface to calculate altitude of the surface. ICESat-2 measurements can be combined with ship-based sonar data to fill in gaps and ...
The laser pulse can also be reflected by the surface of a satellite without a retroreflector, which is used for tracking space debris. [1] Satellite laser ranging is a proven geodetic technique with significant potential for important contributions to scientific studies of the earth/atmosphere/ocean system. It is the most accurate technique ...
