CHAPEA, which stands for Crew Health and Performance Exploration Analog, is a series of analog missions designed to simulate year-long stays on the surface of Mars. These missions aim to provide valuable data on various factors, including physical and behavioral health and performance. The simulations take place at the Johnson Space Center in Houston, Texas, and the first mission, CHAPEA 1, commenced on June 25, 2023.
The Habitat
Mars Dune Alpha, the habitat used for the CHAPEA missions, is a 3D printed structure spanning an area of 1,700 square feet. It is equipped with all the necessary facilities to support the crew during their stay. The habitat includes private crew quarters, a kitchen, dedicated areas for medical care, recreation, fitness, work, and crop growth activities, as well as a technical work area and two bathrooms.
Goals of CHAPEA
The primary goal of the CHAPEA missions is to gather accurate and comprehensive data by creating a Mars-realistic environment. This includes incorporating environmental stressors such as limited resources, isolation, equipment failures, and demanding workloads. The crew members engage in various activities throughout the analog mission, including simulated spacewalks with virtual reality, communication tasks, crop growth experiments, meal preparation and consumption, exercise routines, personal hygiene, maintenance work, scientific research, and sleep patterns.
CHAPEA Mission Schedule
The CHAPEA missions are planned to be conducted over a period of several years. As of now, the schedule includes the following missions:
Analog mission 1 – Began on June 25, 2023
Analog mission 2 – Planned to start in 2025
Analog mission 3 – Planned to start in 2026

Significance of CHAPEA
The knowledge and insights gained from the CHAPEA analog missions can have a profound impact on future NASA missions, particularly those involving human exploration of Mars. The research conducted during these missions will contribute to understanding how to best support crew health and performance during long-duration space exploration missions.
NASA emphasizes the importance of CHAPEA by stating, "The inaugural CHAPEA mission began to determine how to best support crew health and performance while living on Mars during a long-duration exploration mission." This indicates that the findings and experiences from CHAPEA will play a crucial role in shaping the future of human space exploration.
The Crew of CHAPEA 1

The first CHAPEA mission, known as CHAPEA 1, involves a crew of four individuals, each with their specific role and expertise:
Kelly Haston – Research Scientist and Commander of the mission.
Ross Brockwell – Structural Engineer and Flight Engineer of the mission.
Nathan Jones – Emergency Medicine Physician and Medical Officer of the mission.
Yasmina Mirza – Microbiologist and Science Officer of the mission.
The primary objective of CHAPEA 1 is to study the effects of long-term isolation and confinement on crew health and performance. The crew members will reside and work in a simulated Mars habitat, exposing themselves to a range of stressors, including communication delays, limited resources, and challenging environmental conditions.
During the CHAPEA simulations, the crew will engage in various mission activities, such as simulated spacewalks, robotic operations, habitat maintenance, personal hygiene routines, exercise sessions, and crop growth experiments. These activities aim to replicate the conditions and challenges that astronauts might encounter during future Mars missions.
