These estimates are applicable to an array of satellites orbiting the Earth. For space vehicles or space stations, the range of communications is estimated to increase up to 10,000 km (6,200 mi). [84] This approach to secure space-to-space communications was selected by Laser Focus World as one of the top photonics developments of 2015. [85]
Optical PAyload for Lasercomm Science (OPALS) is a spacecraft communication instrument developed at the Jet Propulsion Laboratory that was tested on the International Space Station (ISS) from 18 April 2014 to 17 July 2014 to demonstrate the technology for laser communications systems between spacecraft and ground stations.
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.
Dogs do not have red-sensing cones, so their sight is similar to that of someone with red-green color blindness, according to research by Jay Neitz, a professor of ophthalmology and a color vision ...
To get to the bottom of why cats chase lasers, we called in expert vet Dr. Hannah Godfrey. Below, she explains why they find them so appealing and whether lasers cause anxiety in cats .
On other space missions, astronauts reported seeing other colors such as yellow and pale green, though rarely. [10] Others instead reported that the flashes were predominantly yellow, while others reported colors such as orange and red, in addition to the most common colors of white and blue.
NASA's Vision Mission for the Innovative Interstellar Explorer considered using optical-laser communication, as did the 1980s era TAU probe. It has also been proposed that higher frequency signals, such as lasers operating at visible light frequencies, may prove to be a fruitful method of interstellar communication; at a given frequency it takes surprisingly small energy output for a laser ...
Lasers are being used for long-distance high-bandwidth communications and accuracy in air-to-air laser connectivity is important for data integrity. Scintillation is also a problem in development of weaponized lasers, such as the airborne laser being developed to intercept intercontinental ballistic missiles .
