4 Min Read NASA Uses Colorado Mountains for Simulated Artemis Moon Landing Course
NASA has certified a new lander flight training course using helicopters, marking a key milestone in crew training for Artemis missions to the Moon. Through Artemis, NASA explore the lunar South Pole, paving the way for human exploration farther into the solar system, including Mars.
The mountains in northern Colorado offer similar visual illusions and flight environments to the Moon. NASA partnered with the Colorado Army National Guard at the High-Altitude Army National Guard Aviation Training Site near Gypsum, Colorado, to develop the foundational flight training course.
“Artemis astronauts who will land on the Moon will need to master crew coordination and communication with one another,” said Paul Felker, acting deputy director of flight operations at NASA’s Johnson Space Center in Houston. “Much like they will on the Moon, astronaut teams are learning how to work together efficiently in a stressful environment to identify hazards, overcome degraded visual environments, and evaluate risks to successfully land.”
During the two-week certification run in late August, NASA astronauts Mark Vande Hei and Matthew Dominick participated in flight and landing training to help certify the course. The pair took turns flying a helicopter and navigating to landing zones. Artemis flight crew trainers, mission control leads, and lunar lander operational experts from NASA Johnson joined them on each helicopter flight to assess the instruction, training environment, and technical applications for crewed lunar missions.

NASA and the Colorado Army National Guard began working together in 2021 to develop a foundational lunar lander simulated flight training course for Artemis. NASA The NASA astronauts and trained instructor pilots with the Army National Guard flew to progressively more challenging landing zones throughout the course, navigating the mountainous terrain, and working together to quickly and efficiently land the aircraft.
Teams can train year-round using the course. Depending on the season, the snowy or dusty conditions can cause visual obstruction. Lunar dust can cause similar visual impairment during future crewed missions.
“Here in Colorado, we have specifically flown to dusty areas, so we know and understand just how important dust becomes during the final descent phase,” Vande Hei said. “Dust will interact with the lander thrusters on the Moon. During our flight training, we have had to revert to our instruments – just like we would on the Moon – because astronauts may lose all their visual cues when they’re near the surface.”
During Artemis III, four astronauts inside the agency’s Orion spacecraft on top of the SLS (Space Launch System rocket) will launch to meet SpaceX’s Starship Human Landing System in lunar orbit. Orion will then dock with the Starship system and two astronauts will board the lander. Astronauts will use the Starship lander to safely transport themselves from lunar orbit to the lunar surface. Following surface operations, the two astronauts will use Starship to launch from the lunar surface, back to lunar orbit, and dock with Orion to safely journey back to Earth.
The NASA-focused course has been in development since 2021. Vande Hei and Dominick are the 24th and 25th NASA astronauts to participate in and evaluate the course based on functionality and Artemis mission needs. One ESA (European Space Agency) astronaut has also participated in the course.
“This course will likely be one of the first group flight training opportunities for the Artemis III crew,” said NASA astronaut Doug Wheelock, who helped to develop the foundational training course for the agency. “While the astronauts will also participate in ground and simulation training in Ohio and Texas, the real-world flight environment in Colorado at offers astronauts an amazing simulation of the problem solving and decision making needed to control and maneuver a lunar lander across an equally dynamic landscape.”
Though the course is now certified for Artemis, teams will continue to evaluate the training based on astronaut and technical feedback to ensure mission success and crew safety.
Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars for the benefit of all.

A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken from a rock named “Cheyava Falls” last year, the sample, called “Sapphire Canyon,” contains potential biosignatures, according to a paper published Wednesday in the journal Nature.
A potential biosignature is a substance or structure that might have a biological origin but requires more data or further study before a conclusion can be reached about the absence or presence of life.
“This finding by Perseverance, launched under President Trump in his first term, is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,” said acting NASA Administrator Sean Duffy. “NASA’s commitment to conducting Gold Standard Science will continue as we pursue our goal of putting American boots on Mars’ rocky soil.”
NASA’s Perseverance rover discovered leopard spots on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.Credit: NASA/JPL-Caltech/MSSS NASA’s Perseverance Mars rover took this selfie, made up of 62 individual images, on July 23, 2024. A rock nicknamed “Cheyava Falls,” which has features that may bear on the question of whether the Red Planet was long ago home to microscopic life, is to the left of the rover near the center of the image.Credit: NASA/JPL-Caltech/MSSS Perseverance came upon Cheyava Falls in July 2024 while exploring the “Bright Angel” formation, a set of rocky outcrops on the northern and southern edges of Neretva Vallis, an ancient river valley measuring a quarter-mile (400 meters) wide that was carved by water rushing into Jezero Crater long ago.
“This finding is the direct result of NASA’s effort to strategically plan, develop, and execute a mission able to deliver exactly this type of science — the identification of a potential biosignature on Mars,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “With the publication of this peer-reviewed result, NASA makes this data available to the wider science community for further study to confirm or refute its biological potential.”
The rover’s science instruments found that the formation’s sedimentary rocks are composed of clay and silt, which, on Earth, are excellent preservers of past microbial life. They also are rich in organic carbon, sulfur, oxidized iron (rust), and phosphorous.
“The combination of chemical compounds we found in the Bright Angel formation could have been a rich source of energy for microbial metabolisms,” said Perseverance scientist Joel Hurowitz of Stony Brook University, New York and lead author of the paper. “But just because we saw all these compelling chemical signatures in the data didn’t mean we had a potential biosignature. We needed to analyze what that data could mean.”
First to collect data on this rock were Perseverance’s PIXL (Planetary Instrument for X-ray Lithochemistry) and SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instruments. While investigating Cheyava Falls, an arrowhead-shaped rock measuring 3.2 feet by 2 feet (1 meter by 0.6 meters), they found what appeared to be colorful spots. The spots on the rock could have been left behind by microbial life if it had used the raw ingredients, the organic carbon, sulfur, and phosphorus, in the rock as an energy source.
In higher-resolution images, the instruments found a distinct pattern of minerals arranged into reaction fronts (points of contact where chemical and physical reactions occur) the team called leopard spots. The spots carried the signature of two iron-rich minerals: vivianite (hydrated iron phosphate) and greigite (iron sulfide). Vivianite is frequently found on Earth in sediments, peat bogs, and around decaying organic matter. Similarly, certain forms of microbial life on Earth can produce greigite.
The combination of these minerals, which appear to have formed by electron-transfer reactions between the sediment and organic matter, is a potential fingerprint for microbial life, which would use these reactions to produce energy for growth. The minerals also can be generated abiotically, or without the presence of life. Hence, there are ways to produce them without biological reactions, including sustained high temperatures, acidic conditions, and binding by organic compounds. However, the rocks at Bright Angel do not show evidence that they experienced high temperatures or acidic conditions, and it is unknown whether the organic compounds present would’ve been capable of catalyzing the reaction at low temperatures.
The discovery was particularly surprising because it involves some of the youngest sedimentary rocks the mission has investigated. An earlier hypothesis assumed signs of ancient life would be confined to older rock formations. This finding suggests that Mars could have been habitable for a longer period or later in the planet’s history than previously thought, and that older rocks also might hold signs of life that are simply harder to detect.
“Astrobiological claims, particularly those related to the potential discovery of past extraterrestrial life, require extraordinary evidence,” said Katie Stack Morgan, Perseverance’s project scientist at NASA’s Jet Propulsion Laboratory in Southern California. “Getting such a significant finding as a potential biosignature on Mars into a peer-reviewed publication is a crucial step in the scientific process because it ensures the rigor, validity, and significance of our results. And while abiotic explanations for what we see at Bright Angel are less likely given the paper’s findings, we cannot rule them out.”
The scientific community uses tools and frameworks like the CoLD scale and Standards of Evidence to assess whether data related to the search for life actually answers the question, Are we alone? Such tools help improve understanding of how much confidence to place in data suggesting a possible signal of life found outside our own planet.
Marked by seven benchmarks, the Confidence of Life Detection, or CoLD, scale outlines a progression in confidence that a set of observations stands as evidence of life.

A view inside the sandbox portion of the Crew Health and Performance Analog, where research volunteers participate in simulated walks on the surface of Mars. Credit: NASA Four research volunteers will soon participate in NASA’s year-long simulation of a Mars mission inside a habitat at the agency’s Johnson Space Center in Houston. This mission will provide NASA with foundational data to inform human exploration of the Moon, Mars, and beyond.
Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer enter into the 1,700-square-foot Mars Dune Alpha habitat on Sunday, Oct. 19, to begin their mission. The team will live and work like astronauts for 378 days, concluding their mission on Oct. 31, 2026. Emily Phillips and Laura Marie serve as the mission’s alternate crew members.
Through a series of Earth-based missions called CHAPEA (Crew Health and Performance Exploration Analog), carried out in the 3D-printed habitat, NASA aims to evaluate certain human health and performance factors ahead of future Mars missions. The crew will undergo realistic resource limitations, equipment failures, communication delays, isolation and confinement, and other stressors, along with simulated high-tempo extravehicular activities. These scenarios allow NASA to make informed trades between risks and interventions for long-duration exploration missions.
“As NASA gears up for crewed Artemis missions, CHAPEA and other ground analogs are helping to determine which capabilities could best support future crews in overcoming the human health and performance challenges of living and operating beyond Earth’s resources – all before we send humans to Mars,” said Sara Whiting, project scientist with NASA’s Human Research Program at NASA Johnson.
Crew members will carry out scientific research and operational tasks, including simulated Mars walks, growing a vegetable garden, robotic operations, and more. Technologies specifically designed for Mars and deep space exploration will also be tested, including a potable water dispenser and diagnostic medical equipment.
“The simulation will allow us to collect cognitive and physical performance data to give us more insight into the potential impacts of the resource restrictions and long-duration missions to Mars on crew health and performance,” said Grace Douglas, CHAPEA principal investigator. “Ultimately, this information will help NASA make informed decisions to design and plan for a successful human mission to Mars.”
This mission, facilitated by NASA’s Human Research Program, is the second one-year Mars surface simulation conducted through CHAPEA. The first mission concluded on July 6, 2024.
The Human Research Program pursues methods and technologies to support safe, productive human space travel. Through applied research conducted in laboratories, simulations, and aboard the International Space Station, the program investigates the effects spaceflight has on human bodies and behaviors to keep astronauts healthy and mission-ready.
