Artemis 2 astronauts did CPR tests as they cruised toward the moon on Flight Day 3. This critical deep-space medical rehearsal ensures the crew is prepared for life-saving emergencies during their 10-day journey around the moon.
NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen are cruising toward the moon. After an intense launch on April 1, the mission pace has finally eased.
Flight Day 3 focuses on medical readiness and deep-space life-saving techniques. The crew is also testing a zero-gravity flywheel to maintain muscle mass and bone density during their historic lunar loop.
Discovering how artemis 2 astronauts did CPR tests
Artemis 2 astronauts did CPR tests to prepare for medical emergencies during their lunar voyage. By practicing microgravity resuscitation and checking diagnostic gear, NASA ensures the crew can handle high-stakes health crises in deep space.
Artemis 2 astronauts did CPR tests on Flight Day 3 to verify that medical equipment like thermometers, stethoscopes, and otoscopes function correctly. These drills are part of a broader effort to ensure the crew remains healthy while cruising toward the moon.
Astronauts Glover, Koch, and Hansen led the demonstrations while Wiseman checked the medical kit. This ensures that the crew can handle potential medical crises without immediate ground support while far from Earth.
The mission pace on Flight Day 3 is more relaxed compared to the action-packed launch sequence. This allows time for critical safety rehearsals before the high-stakes moon flyby on April 6.
Deep space medical kit validation
Maintaining crew health is essential as artemis 2 astronauts did CPR tests to simulate emergency scenarios in microgravity. The Orion spacecraft carries a specialized medical suite, including blood pressure monitors and diagnostic tools, which are vital for a crew venturing further from Earth than any mission since 1972.
Orion spacecraft manual flight trials
Pilot Victor Glover recently test-drove the Orion capsule near the SLS upper stage to confirm manual precision. He confirmed artemis 2 astronauts did CPR tests and flight maneuvers to ensure the spacecraft handles correctly during its high-stakes shakedown.

| Exercise Test | Wiseman, Glover | Flywheel Rowing Machine |
| Flight Control | Victor Glover | Orion Manual Thrusters |
Scientific importance and theories
Space medicine theories suggest that performing resuscitation in microgravity requires unique positioning to compensate for weightlessness.
As artemis 2 astronauts did CPR tests, researchers gathered data on the physical force required for compressions in deep space, which is critical for future Mars missions and sustainable lunar bases.
Testing zero gravity fitness systems
Physical conditioning is another priority while artemis 2 astronauts did CPR tests and health checks. Reid Wiseman tested a new flywheel device, describing it as a high-quality piece of gear for maintaining strength during the long voyage home.
Historic mission milestones achieved
The crew has surpassed several critical milestones since their April 1 launch, building confidence in the Orion platform:
- Aced the translunar injection (TLI) burn to fling into deep space.
- Conducted proximity operations within 50 feet of the rocket stage.
- Stored emergency water supplies after a minor valve glitch.
- Repaired the onboard space toilet for continued operational use.
Implications and what comes next
NASA will now monitor the crew’s progress as they approach the moon flyby on April 6. These medical drills prepare them for the radiation-heavy environment of deep space exploration.
The results from these tests will influence how medical kits are designed for Artemis 3 and beyond. Establishing robust emergency protocols is necessary for long-term lunar surface habitation and future missions.
Conclusion
Rehearsing safety protocols remains a top priority even as the mission pace eases during the lunar transit. Knowing that artemis 2 astronauts did CPR tests successfully ensures the crew’s readiness for any medical emergency. Explore more on our YouTube channel—join NSN Today.
