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.

As we prepare for Artemis III, the first crewed docking missions with the new lunar landers, our focus is on integrating human factors and human systems requirements into key areas to guarantee the performance and success leading up to the lunar landing. This includes refining prebreath protocols and DCS mitigation strategies for the new suit and vehicle pressure regimes, advancing metabolic modeling for the xEMU architecture, and developing robust approaches to lunar dust exposure, autonomous medical care, and partial‑gravity physiology. These efforts build on the continuous stream of biomedical knowledge generated through ISS expeditions and commercial crew operations with SpaceX and Boeing, where investigations into SANS, venous thrombosis, neurovestibular response, bone health, immune adaptation, and behavioral health continue to refine our understanding of long‑duration human performance. Complementing this work, the IGNITE program under Administrator Isaacman is accelerating the maturation of lunar‑relevant technologies, from EVA systems to autonomous diagnostics, ensuring that our operational readiness keeps pace with our exploration ambitions.

Even as we advance human spaceflight, NASA’s science missions continue to expand our understanding of the universe and inspire the next generation of explorers. The Nancy Grace Roman Space Telescope will soon open a new era of wide‑field infrared astronomy, enabling precision cosmology and deep‑sky mapping that complement the extraordinary discoveries of the James Webb Space Telescope, which continues to reveal early‑universe structures, characterize exoplanet atmospheres, and uncover complex chemistry in star‑forming regions. Together, these scientific achievements and human‑exploration milestones reflect a unified commitment across NASA: to push the boundaries of knowledge, to safeguard the health and performance of our crews, and to enable humanity to explore farther, stay longer, and thrive beyond Earth.

We are working hard to enhance our training and competencies for the upcoming missions. There are so many new systems and architectures, and changing risks with exploration mission architectures, that it requires us to up our game. The skills our flight surgeons, biomedical engineers, technical authorities, and researchers need to know is evolving and expanding exponentially. In addition to our Tech Sheets, Standards, Clinical Practice Guidelines, and Human Systems Work on our website, you will begin to see research papers and white papers, exploring not only physiology and medicine, but technologies and innovation. It’s important for us to share our lessons learned, not only for ourselves and our partners, but for everyone involved in the greater human spaceflight ecosystem. We want everyone to be successful and safe in human spaceflight: “all boats float with a rising tide”.
