The Space Force is launching lasers into orbit
WORDS SAMANTHA MATHEWSON
The Space Force aims to better pinpoint the location of Earth’s true centre using lasers on GPS satellites, slated to launch in 2025.
A set of Laser Retroreflector Arrays, or LRAs, will be installed onto two GPS III satellites, SV9 and SV10, as part of NASA’s Space Geodesy Program. The lasers are designed to make precise sub-centimetre measurements using a technique called Satellite Laser Ranging, which will allow researchers to more accurately determine Earth’s centre.
