    In January 2013, NASA tested one-way laser communication with LRO by sending an image of the Mona Lisa to the Lunar Orbiter Laser Altimeter (LOLA) instrument on LRO from the Next Generation Satellite Laser Ranging (NGSLR) station at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

    The flash lidar flashes a laser and acts like a flash camera permitting the generation of lidar maps and images. [10] The Doppler lidar measures the vehicle's altitude and velocity to precisely land on the surface, and the high-altitude laser altimeter provides data enabling the vehicle to land in the chosen area. [10]

  4. Laser communication in space - Wikipedia

    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.

    The Laser Altimeter could measure the height of the CSM above the lunar surface to within one meter. It used a pulsed ruby laser operating at 694.3 nanometers and 200 millijoule pulses of 10 nanoseconds duration. The Stellar Camera was used during the runs of the Laser Altimeter on the night side of the Moon.

    The Laser Communications Relay Demonstration (LCRD) is a NASA mission that will test laser communication in space for extremely long distances, [1] between Earth and geosynchronous orbit. After being integrated into STPSat-6 , a part of STP-3 , LCRD launched on 7 December 2021 on an Atlas V 551.

    Founded as Beltsville Space Center, Goddard was NASA's first of four space centers. Its original charter was to perform five major functions on behalf of NASA: technology development and fabrication, planning, scientific research, technical operations, and project management.

  8. 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 ...

    MOLA topographic images of the two hemispheres of Mars. This image appeared on the cover of Science magazine in May 1999. The Mars Orbiter Laser Altimeter (MOLA) was one of five instruments on the Mars Global Surveyor (MGS) spacecraft, which operated in Mars orbit from September 1997 to November 2006. However, the MOLA instrument transmitted ...
