The Artemis 2 mission by NASA will involve science experiments on astronaut health to investigate sleep, stress, immunity, and radiation in deep space.

The Artemis 2 mission of NASA, which is to be launched in early 2026, should be the first crewed flight of the Orion spacecraft and Space Launch System rocket. In addition to the hardware testing, the mission will also be an important science project, with the emphasis being on the effect of deep space on human health.

The four astronauts, including Reid Wiseman, Victor Glover, Christina Koch and Canadian Space Agency astronaut Jeremy Hansen, will participate in various science experiments throughout their ten-day trip around the moon. They will submit blood, urine and saliva samples prior to, during and after flight to assist NASA in monitoring the changes in cardiovascular well-being, stress and immunity.

Such projects as ARCHeR will examine sleep and stress patterns with the help of wearable wrist sensors, and the markers of the immune system will be monitored to evaluate the impact of radiation and microgravity on biological reactions. AVATAR is another experiment that will involve organ-on-a-chip models that mimic bone marrow to investigate how tissues respond to radiation from the magnetosphere of the earth.

Radiation will also be monitored closely with dosimeters on astronauts and monitors in Orion and contingency shields are already in place in case of a solar storm.

A combination of high-level spaceflight experimentation and state-of-the-art biomedical research, Artemis 2 will broaden the understanding of human deep space adaptation, which will be the foundation of future successful lunar exploration and journeys to Mars.
