NASA is sending 2 probes to the moon to test complex 'three-body orbits'

NASA is planning to send two maneuverable probes to lunar orbit in order to learn how spacecraft are affected by the complex gravitational environment near the moon.

The mission, known as CAPSTONE 02, is currently aiming to launch in 2027. It will see the two probes maneuver in close proximity to one another and fly in "formation" so mission operators can better understand the gravitational effects spacecraft experience in cislunar space. This area of space is under the influence of both Earth's gravity and the moon's, meaning spacecraft operating there will have to navigate what are known as "three-body orbits."

While testing spacecraft maneuverability in these complex orbits, CAPSTONE 02 will also study communication and navigation systems that will be used in NASA's planned Artemis missions of lunar exploration and moon base construc...
