Analog Missions:
Advancing Human Space Exploration
Analog missions are scientific campaigns conducted on Earth to simulate the conditions of future exploration on a Solar System body, such as the Moon or Mars. These environments recreate conditions and operational constraints associated with long-duration missions in space, including isolation, resource limitations, or challenging terrain.
Through these simulations, researchers and crews gain valuable experience that will contribute directly to the success of future human expeditions beyond Earth.
Hypatia Mars Missions
The Hypatia missions are two-week expeditions conducted at a Mars analog research station. During these missions, the crews carry out high-quality space-related research while rigorously simulating their daily life on Mars. Living in a small habitat and without manyof Earth’s comforts, they experience first hand the challenges that astronauts may face on the Red Planet.
These missions also serve as a platform to highlight female role models in STE(A)M. Children and young people are introduced to real and relatable women scientists from different fields — such as astrophysics, mathematics, engineering, and biology — who are part of the crew. The stories of these professionals have the potential to inspire future generations and encourage them to pursue careers in these fields.
Why Are Analog Missions Essential?
They enable us to test, and validate critical components of space exploration before humanity learns to travel beyond Earth.
Analog missions allow teams to:
- Practice crew coordination and mission operations
- Conduct simulated extravehicular activities (EVAs) and field science
- Study habitability and human performance in confined environments
- Develop and evaluate scientific equipment and exploration technologies
- Test logistics, safety procedures, and emergency response protocols
The knowledge gained significantly reduces operational risks and improves planning for future crewed missions to the Moon and Mars
A Global Network of Analog Research Facilities
Around the world, a growing network of analog research facilities helps prepare future human missions to the Moon and Mars. These facilities are operated by a wide range of organizations —including space agencies, universities, nonprofit organizations, and international research groups— and provide unique capabilities to simulate space exploration.
Some locations focus on human performance and mission operations, others on robotics, field science, habitat engineering, or life-support systems in extreme conditions.

Major Analog
Iniciatives
In total, more than 15 major analog initiatives worldwide contribute to advancing operational readiness, crew safety, and scientific knowledge for future human missions.
Representative programs include:
- NEEMO — NASA Extreme Extreme Environment Mission Operations (Florida, USA) — underwater habitats that allow testing human and robotic exploration operations and crew training techniques to support space exploration
- Concordia — ESA Analog Station (Antarctica) — remote, extreme isolation and harsh environment conditions for studying human physiology, psychology and team dynamics
- MDRS — Mars Desert Research Station (Utah, USA) — Mars-focused operational research and crew simulations
- FMARS — Flashline Mars Arctic Research Station (Devon Island, Canada) — polar isolation and Mars-like terrain in the High Arctic
- HI-SEAS — Hawai‘i Space Exploration Analog and Simulation (Hawaii, USA) — long-duration isolation missions on volcanic environments resembling Martian geology
The Hypatia missions are currently conducted at analog stations operated by the Mars Society, one of the most established private entities managing analog stations dedicated to Mars exploration.
The Mars Desert Research Station
The Mars Desert Research Station (MDRS), operated by The Mars Society since 2001, is located in the Utah desert, where the landscape provide the opportunity to conduct Mars-related research and mission simulations.
More than 300 international crews have carried out scientific and operational investigations at MDRS, strengthening our readiness for human exploration of the Red Planet.

International Crews
at MDRS
MDRS Infrastructure
The MDRS base is designed to emulate a future Martian outpost and includes:
Main Hab
— central habitat for mission planning, living, and crew operations
Science Dome
— fully equipped laboratory for sample analysis and research activities
Astronomical Observatories
— two robotic telescope to observe the Sun and the night sky
GreenHab
— controlled environment for plant growth and food production studies
RAM
— repair and maintenance module for equipment and technology
Rovers
— enabling safe and structured field exploration
All surface operations outsidethe martian base are conducted in simulated spacesuits to maintain mission realism and safety.
The Flashline Mars Arctic Research Station
The Flashline Mars Arctic Research Station (FMARS), operated by The Mars Society since 2001, is located on Devon Island in the Canadian High Arctic. The station provides a unique opportunity to conduct Mars-related research and mission simulations under extreme polar conditions.
Fewer than 20 international crews have conducted scientific and operational investigations at Flashline, providing valuable insights into human exploration of Mars and helping to refine mission strategies for the Red Planet.

International Crews
at Flashline
Flashline Infrastructure
The FMARS base is designed as a Mars analog habitat and includes the following components:
FMARS Habitat
— the main living space, serving as an area for life, work, and research during simulations
Generator Shack
— a separate structure housing two generators that supply power to the habitat
Rovers
— features a robotic telescope to observe the night sky
Missions at Flashline require all surface operations outside the base to be conducted in simulated spacesuits with delayed communications, replicating the conditions of a real Mars mission.
Paving the Way to Mars
Analog missions are a vital bridge between conceptual mission design and true human presence on other worlds.
By integrating scientific research, technological testing, and human factors studies, the analog facilities help prepare teams for the complexities of life and work in space.
Each mission contributes to building the operational expertise required to take humanity’s next giant leap.
