NASA's Artemis II mission has launched, marking the first crewed lunar flight in over 50 years. The Orion spacecraft will carry an optical communications system developed by MIT Lincoln Laboratory, allowing it to transmit high-resolution video and images of the lunar surface back to Earth at much higher data rates than traditional radio-frequency systems.

Why it matters

Space-based communications has long been a challenge, with the radio-frequency spectrum becoming increasingly congested. Laser communications offer a solution that can handle the growing data demands of deep-space exploration. The success of the Artemis II mission's optical communications system could pave the way for future lunar and Mars missions to livestream video, coordinate activities, and stay in real-time contact with Earth.

The details

The Orion spacecraft's Optical Communications System (O2O) was developed by a team from MIT Lincoln Laboratory and NASA's Goddard Space Flight Center. At the heart of O2O is the laboratory's Modular, Agile, Scalable Optical Terminal (MAScOT), a compact laser communications system that can precisely track and transmit data via laser beams. MAScOT previously demonstrated its capabilities on the International Space Station, achieving data rates up to 1.2 Gbps down and 155 Mbps up.

  • The Artemis II mission launched on April 3, 2026.
  • The 10-day mission will orbit the moon, testing the O2O laser communications system.

What they’re saying

“Space-based communications has always been a big challenge. RF communications have served their purpose well. However, the RF spectrum is highly congested now, and RF does not scale well to longer distances across space. Laser communication [lasercom] is a solution that could solve this problem, and the laboratory is an expert in the field, which was really pioneered here.”

— Farzana Khatri, Senior staff member, Optical and Quantum Communications Group, MIT Lincoln Laboratory

“Our success with ILLUMA-T laid the foundation for streaming HD [high-definition] video to and from the moon. You can imagine the Artemis astronauts using videoconferencing to connect with physicians, coordinate mission activities, and livestream their lunar trips.”

— Jade Wang, Assistant leader, Optical and Quantum Communications Group, MIT Lincoln Laboratory

What’s next

The Artemis II mission will pave the way for future Artemis missions, which aim to land astronauts on the moon and prepare for a lasting lunar presence, and eventually human missions to Mars.

The takeaway

The successful demonstration of laser communications during the Artemis II mission represents a major technological advancement that could revolutionize how spacecraft communicate, enabling higher-bandwidth data transmissions and real-time video connections between astronauts and Earth.
