    en.wikipedia.org/wiki/Autonomous_Landing_Hazard...

    NASA Langley created three lidar (light radar) sensors: the flash lidar, Doppler lidar and high-altitude laser altimeter for the ALHAT project. [10] The flash lidar uses imagery technology to detect objects larger than the size of a basketball on a planetary surface under all lighting conditions.

  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. MESSENGER - Wikipedia

    en.wikipedia.org/wiki/MESSENGER

    MESSENGER was a NASA robotic space probe that orbited the planet Mercury between 2011 and 2015, studying Mercury's chemical composition, geology, and magnetic field. [9] [10] The name is a backronym for Mercury Surface, Space Environment, Geochemistry, and Ranging, and a reference to the messenger god Mercury from Roman mythology.

    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. [50]

  8. TOPEX/Poseidon - Wikipedia

    en.wikipedia.org/wiki/TOPEX/Poseidon

    TOPEX/Poseidon flew two onboard altimeters sharing the same antenna, but only one altimeter was operated at any time, with TOPEX given preference (on average 9 in 10 cycles during the first 10 years of the mission). TOPEX: The NASA-built Nadir pointing Radar Altimeter using C band (5.3 GHz) and Ku band (13.6 GHz) for measuring height above sea ...
