NASA’s Goddard Space Flight Center (NASA’sGoddardSpaceFlightCenter), researchers are working to study the future of space flight and remote sensing instruments used in laser launchers, including for the ice cover and marine ice monitoring micro-pulse laser altimeter, A laser spectroscopy instrument for atmospheric carbon dioxide detection, and a laser imaging radar for high-resolution imaging of the Earth’s surface cnc punching machine. In addition, these flying loads can also be used for the detection of the atmosphere of other stars in the solar system and for the imaging of the stars cnc machining center. In this paper, we first summarize NASA’s previous space-borne laser-borne launchers for Mars, Mercury, Earth and Lunar Orbit, and then synthesize the current space flight laser load projects, and introduce their science of proximity sensing And to explore the use of the expected results.
There are three laser loads in use today, and their mission is to use scientific data on the Earth induction welding, Moon, and Mercury so that we can more deeply understand our planet and the solar system. All of these radar systems use a semiconductor laser array-pumped high power quasi-persistent solid-state laser as a light source. The first solid-state laser pumped on-board semiconductor laser was the Mars satellite laser altimeter, which was launched in 1996 and provides a large number of high-resolution Mars profiles. Subsequently, in 2003, a laser altimeter was launched for earth sciences research. The laser load currently in use is the cloud-aerosol orthogonal polarimetric lidar, the Mercury laser altimeter, and the lunar satellite laser altimeter, which was launched in 2006. Although the current semiconductor-pumped solid-state lasers in space has made great success, but still can not meet the requirements of future laser radar. Therefore, it is necessary to develop a new type of space laser for future proximity sensing.
