The laser array is rotated 2 degrees from the satellite's ground track so that a beam pair track is separated by about 90 m (300 ft). The laser pulse rate combined with satellite speed results in ATLAS taking an elevation measurement every 70 cm (28 in) along the satellite's ground path. [17] [19] [20] The laser fires at a rate of 10 kHz.
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.
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]
Digital Mapping System (DMS) - The Digital Mapping System (DMS), created by researchers at NASA's Ames Research Center, is an airborne digital imaging system that is used to detect openings in sea ice and build high-resolution maps of polar ice. The DMS instrument is a downward-facing digital camera that captures multiple individual frames that ...
Nasa hopes that the laser technology can help empower future crewed missions to Mars, among other exploration of our solar system, and so the successful test marks a major breakthrough. “The ...
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.
NASA’s laser communications experiment just beamed back a video from space for the first time, and it features a cat named Taters chasing a laser pointer.
