    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.

  4. ICESat - Wikipedia

    en.wikipedia.org/wiki/ICESat

    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.

  5. Laser communication in space - Wikipedia

    en.wikipedia.org/wiki/Laser_communication_in_space

    The LLCD is NASA's first attempt at two-way space communication using an optical laser instead of radio waves, and is expected to lead to operational laser systems on NASA satellites in future years. [16] In November 2013, laser communication from a jet platform Tornado was successfully demonstrated for the first time.

  6. Mars Orbiter Laser Altimeter - Wikipedia

    en.wikipedia.org/wiki/Mars_Orbiter_Laser_Altimeter

    A laser altimeter is an instrument that measures the distance from an orbiting spacecraft to the surface of the planet or asteroid that the spacecraft is orbiting. The distance is determined by measuring the complete round trip time of a laser pulse from the instrument to the body's surface, and back to the instrument.

    The Software Assurance Technology Center (SATC) is a NASA department founded in 1992 as part of their Systems Reliability and Safety Office at Goddard Space Flight Center. Its purpose was "to become a center of excellence in software assurance, dedicated to making measurable improvement in both the quality and reliability of software developed ...

  8. OSIRIS-REx - Wikipedia

    en.wikipedia.org/wiki/OSIRIS-REx

    The OSIRIS-REx Laser Altimeter (OLA) is a scanning and lidar instrument that will provide high resolution topographical information throughout the mission. [97] The information received by OLA creates global topographic maps of Bennu, local maps of candidate sample sites, ranging in support of other instruments, and support navigation and ...

  9. Bathymetry - Wikipedia

    en.wikipedia.org/wiki/Bathymetry

    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 ...
