- Artemis II mission used the Orion Artemis II Optical Communications System (O2O) to livestream high-definition footage from the moon.
- O2O employed laser communications (lasercom) for high-speed data transmission, surpassing radio-frequency systems in bandwidth.
- The system downlinked nearly half a terabyte of data at speeds up to 260 Mbps, enabling real-time multimedia sharing.
- O2O's success allowed mission control to preserve and immediately analyze data, avoiding delays and potential corruption.
- Future improvements could increase downlink capacity by at least 10 times, supporting upcoming lunar and deep-space missions.
