NASA tests technology similar to GPS with a probe on the Moon

NASA’s CAPSTONE cubeSat successfully tested GPS-like navigation technology on Earth for the first time, intended to help more efficient space missions to the Moon.

The mission’s Cislunar Autonomous Positioning System is a spacecraft-to-spacecraft navigation and communications system that works with NASA’s Lunar Reconnaissance Orbiter to determine the distance between the two spacecraft in lunar orbit.

This technology could allow future spacecraft to determine their position in space without relying solely on tracking from Earth. CAPSTONE also has a new precision one-way ranging capability built into its radio that could reduce the amount of ground network time required for operations in space.

The spacecraft also captured its first images of the Moon, showing the lunar surface near the Moon’s North Pole as CAPSTONE approached the Moon on May 3, NASA reports.
Launched in June 2022, CAPSTONE (Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment) last November became the first spacecraft to enter a unique elongated orbit that will support NASA’s Artemis missions.

In this special orbit, formally known as a Near Rectilinear Halo Orbit (NRHO), the pull of Earth’s and Moon’s gravity interact to allow a semi-stable orbit.
