JD's Corner
It’s been a busy year, thus far. We didn’t have any downtime after the splashdown and success of Artemis II. During the mission, the crew conducted a full operational checkout of the Environmental Control and Life Support System, confirming stable performance of oxygen generation, carbon dioxide removal, humidity control, and trace contaminant management under real mission loads. They also demonstrated the proof‑of‑concept exercise hardware designed to maintain musculoskeletal and cardiovascular conditioning during transit, generating data that will shape future countermeasure systems and protocols. Artemis II further delivered critical engineering insight through the lunar‑return re‑entry, where the heat shield’s ablative performance and structural response were measured across thousands of sensors, data that now anchors our modifications for the next heatshield and gives key performance data needed for our certification pathway.
