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 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.
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 ...
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 ...
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 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 ...
Originally, NASA wanted to power the ascent stage using LOX and liquid methane (LCH 4) engines, RS-18, as future missions to Mars would require the astronauts to live on the planet. The Sabatier Reactor could be used to convert the carbon dioxide (CO 2 ) found on Mars into methane, using either found or transported hydrogen, a catalyst , and a ...
