260 Mbps Between Moon and Earth — Communications Technology Powering Artemis II

NASA's Artemis II uses a two-stage radio network and a new laser optical system to maintain Moon–Earth communications.

The O2O laser system, developed with MIT Lincoln Laboratory, is the first lasercom demonstration on a crewed lunar mission.

O2O's MAScOT terminal points a 4-inch telescope with a two-axis gimbal to send infrared laser beams and can transmit up to 260 Mbps, including 4K video.

Orion experienced about 40 minutes of blackout when passing behind the Moon; NASA plans LCRNS relay satellites and chose Intuitive Machines in 2024 to help solve that issue.
