Overview
This video details the intensive four-year simulation program designed to prepare astronauts for a Mars mission to Jezero Crater. Training encompasses psychological endurance in analog habitats, physical adaptation to 38-percent gravity, and scientific skill development in extreme environments. The journey to Mars is won on Earth by testing the mind, body, and science.

Frequently asked questions
- How long do astronauts train on Earth before going to Mars?
- Before humans touch Jezero Crater, they will spend four years simulating every disaster alongside Dr. Mei Lin and Dr. Tariq Al-Fayed.
- What is the CHAPEA habitat?
- NASA's CHAPEA habitat is where four crew members endure a 378-day Mars surface simulation, experiencing 22-minute communication delays to mimic deep space conditions.
- How do astronauts train for Mars's gravity?
- At the Neutral Buoyancy Laboratory, astronauts are submerged in 6.2 million gallons of water with weighted suits to mimic Mars's 38-percent gravity limit.
- What scientific skills do Mars trainees develop?
- Trainees become field geologists during ESA's Pangaea campaign in the Lanzarote volcanic fields, where they hunt for microbial biosignatures deep inside basaltic lava tubes.
- How are astronauts prepared for medical emergencies on Mars?
- Astronauts are trained to perform robotic appendectomies using haptic feedback loops, as a surgical evacuation at Mach 25 is not an option for the 2030s mission.
Transcript
Speaker: Fifty-four million kilometers from Earth, there is no abort protocol. Before humans touch Jezero Crater, they will spend four years simulating every disaster alongside Dr. Mei Lin and Dr. Tariq Al-Fayed.
Speaker: Inside NASA's CHAPEA habitat, four crew members endure a 378-day Mars surface simulation. We enforce 22-minute communication delays to permanently break their reliance on Houston.
Speaker: Gravity is the physical enemy. At the Neutral Buoyancy Laboratory, we submerge astronauts in 6.2 million gallons of water, weighting their prototype suits to mimic Mars's 38-percent gravity limit.
Speaker: But they must also become field geologists. During ESA's Pangaea campaign in the Lanzarote volcanic fields, trainees hunt for microbial biosignatures deep inside basaltic lava tubes.
Speaker: We augment those physical sites with the ARGOS robotic system. A 3D-axis tether unloads the astronaut's mass while VR headsets project a high-resolution topographical map of the Martian south pole.
Speaker: Medical autonomy is terrifying. We train them to perform robotic appendectomies using haptic feedback loops, because a surgical evacuation at Mach 25 simply isn't an option.
Speaker: The 2030s mission requires flawless expeditionary behavior. We isolate them in Antarctic winter-over camps. If a candidate's cortisol spikes during a generator failure, they do not fly.
Speaker: Three takeaways: analog habitats test the mind, 38-percent gravity pools train the body, and volcanic tubes hone the science. Thank you, Mei and Tariq. The journey to Mars is won on Earth.
