Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA employees Broderic J. Gonzalez, left, and David W. Shank install pieces of a 7-foot wing model in preparation for testing in the 14-by-22-Foot Subsonic Wind Tunnel at NASA’s Langley Research Center in Hampton, Virginia, in May 2025. The lessons learned will be shared with the public to support advanced air mobility aircraft development. NASA/Mark Knopp The advanced air mobility industry is currently working to produce novel aircraft ranging from air taxis to autonomous cargo drones, and all of those designs will require extensive testing – which is why NASA is working to give them a head-start by studying a special kind of model wing. The wing is a scale model of a design used in a type of aircraft called a “tiltwing,” which can swing its wing and rotors from vertical to horizontal. This allows the aircraft to take off, hover, and land like a helicopter, or fly like a fixed-wing airplane. This design enables versatility in a range of operating environments.
Several companies are working on tiltwings, but NASA’s research into the scale wing will also impact nearly all types of advanced air mobility aircraft designs.
“NASA research supporting advanced air mobility demonstrates the agency’s commitment to supporting this rapidly growing industry,” said Brandon Litherland, principal investigator for the test at NASA’s Langley Research Center in Hampton, Virginia. “Tool improvements in these areas will greatly improve our ability to accurately predict the performance of new advanced air mobility aircraft, which supports the adoption of promising designs. Gaining confidence through testing ensures we can identify safe operating conditions for these new aircraft.”
NASA researcher Norman W. Schaeffler adjusts a propellor, which is part of a 7-foot wing model that was recently tested at NASA’s Langley Research Center in Hampton, Virginia. In May and June, NASA researchers tested the wing in the 14-by-22-Foot Subsonic Wind Tunnel to collect data on critical propeller-wing interactions. The lessons learned will be shared with the public to support advanced air mobility aircraft development.NASA/Mark Knopp In May and June, NASA tested a 7-foot wing model with multiple propellers in the 14-by-22-Foot Subsonic Wind Tunnel at Langley. The model is a “semispan,” or the right half of a complete wing. Understanding how multiple propellers and the wing interact under various speeds and conditions provides valuable insight for the advanced air mobility industry. This information supports improved aircraft designs and enhances the analysis tools used to assess the safety of future designs.
This work is managed by the Revolutionary Vertical Lift Technology project under NASA’s Advanced Air Vehicles Program in support of NASA’s Advanced Air Mobility mission, which seeks to deliver data to guide the industry’s development of electric air taxis and drones.
“This tiltwing test provides a unique database to validate the next generation of design tools for use by the broader advanced air mobility community,” said Norm Schaeffler, the test director, based at Langley. “Having design tools validated for a broad range of aircraft will accelerate future design cycles and enable informed decisions about aerodynamic and acoustic performance.”
In May and June, NASA researchers tested a 7-foot wing model in the 14-by-22-Foot Subsonic Wind Tunnel at NASA’s Langley Research Center in Hampton, Virginia. The team collected data on critical propeller-wing interactions over the course of several weeks.NASA/Mark Knopp The wing is outfitted with over 700 sensors designed to measure pressure distribution, along with several other types of tools to help researchers collect data from the wing and propeller interactions. The wing is mounted on special sensors to measure the forces applied to the model. Sensors in each motor-propeller hub to measure the forces acting on the components independently.
The model was mounted on a turntable inside the wind tunnel, so the team could collect data at different wing tilt angles, flap positions, and rotation rates. The team also varied the tunnel wind speed and adjusted the relative positions of the propellers.
Researchers collected data relevant to cruise, hover, and transition conditions for advanced air mobility aircraft. Once they analyze this data, the information will be released to industry on NASA’s website.

The Artemis II crew (from left to right) CSA (Canadian Space Agency) Jeremy Hansen, mission specialist; Christina Koch, mission specialist; Victor Glover, pilot; and Reid Wiseman, commander, don their Orion Crew Survival System Suits for a multi-day crew module training beginning Thursday, July 31, 2025 at the agency’s Kennedy Space Center in Florida. Behind the crew, wearing clean room apparel, are members of the Artemis II closeout crew. NASA/Rad Sinyak The first crew slated to fly in NASA’s Orion spacecraft during the Artemis II mission around the Moon early next year entered their spacecraft for a multi-day training at the agency’s Kennedy Space Center in Florida. Crew donned their spacesuits July 31 and boarded Orion to train and experience some of the conditions they can expect on their mission.
NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen participated in a suited crew test and crew equipment interface test, performing launch day and simulated orbital activities inside Orion.
Every milestone in the Artemis campaign brings us closer to landing Americans back on the Moon and pushing onward to Mars.

“In about six months, Artemis II astronauts will journey around the Moon for the first time in 53 years,” Duffy said. “America rallied behind Apollo because it represented the best of us – now it’s Artemis’ turn. They’re not just carrying a flag – they’re carrying the pride, power, and promise of the United States of America.”
With Orion powered on, the suited crew test was a close representation of what the crew can expect on launch day. The crew began the day by suiting up inside the spaceport’s Multi-Operation Support Building, donning their Orion crew survival system spacesuits, boarding the zero-emission crew transportation vehicles, and entering Orion, which is currently inside the Multi-Payload Processing Facility, where engineers have loaded its propellants over the course of several weeks.
Once in Orion, the crew performed several launch day activities, including communications checkouts and suit leak checks. For the first time, the crew was connected to the spacecraft and its communications and life control systems, and all umbilicals were connected while the spacecraft operated on full power.
Teams simulated several different ground and flight conditions to give the crew more experience managing them in real time. Some of the activities simulated scenarios where the crew was challenged to address potential issues while in space such as leaks and failure of the air revitalization system fan, which is needed to provide oxygen and remove carbon dioxide from the cabin. Getting this hands-on experience and learning how to act fast to overcome potential challenges during flight helps ensure the crew is ready for any scenario.
The test provides astronauts the ability to train on the actual hardware they will use during flight, allowing them and support teams the opportunity to familiarize themselves with the equipment in configurations very close to what will be experienced during flight. It also allows teams to verify compatibility between the equipment and systems with flight controller procedures, so they can make any final adjustments ahead of launch.
This test brings together the Artemis II crew and the Orion spacecraft that will carry them to the Moon and back.
Shawn Quinn
NASA's Exploration Ground Systems Program manager
“It signifies the immense amount of work that our operations and development teams put into making sure we are ready for launch.” Quinn said. “They have meticulously planned each operation, timing them to perfection – and now we put it to the test.”
Exchanging their spacesuits for cleanroom garments for the crew equipment interface test, and with the spacecraft powered off, the crew also performed many of the activities they are likely to do in flight and conducted additional equipment checks. The crew practiced removing and stowing the foot pans on the pilot and commander seats, which will allow them to have more open space in the cabin after launch. They also accessed the stowage lockers and familiarized themselves with cameras, associated cables and mounts, and the environmental control and life support system hardware.
In addition to getting practical experience with the actual hardware they’ll use in space, they also prepared for life in deep space, reviewing cabin labels, sleep arrangements and checklists, and the hygiene bay.
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.

NASA A Trip to the Moon
In July 1969, astronauts Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. Now, NASA and its international partners in the Artemis accords are working to send humans back there, this time to stay. The trip will be challenging, especially since space is a very uninviting place for humans! One unexpected source of danger will be the Sun.
The Sun: Friend and Foe
The energy the Sun provides allows life on Earth to thrive. But this energy can also be dangerous to us. This danger can be as simple as getting a sunburn if you are out in the sunlight for too long, or as complex as a geomagnetic storm causing chaos in our satellite network.
This animation demonstrates a simulation by the MAGE model of Earth’s magnetosphere being hit by a geospace storm in May 2024, the strongest in nearly 20 years. Storms like this are caused by solar weather that could endanger astronauts en route to the Moon or active on its surface during future missions. NASA’s Scientific Visualization Studio and CGS Team Things get more complicated in space. On Earth, the atmosphere and magnetosphere protect us from most solar energy. But spacecraft and astronauts in space don’t have this protection. For astronauts on upcoming Artemis missions to the Moon, the Sun’s radiation could cause anything from ruined electronics to a greater long-term risk of cancer.
The Real Risks
On August 2, 1972, a massive solar storm began with the eruption of sunspot MR11976. One of the Coronal Mass Ejections (CMEs) it produced raced from the Sun to Earth in less than 15 hours. That’s a record that still stands today! This led to power grid fluctuations and caused havoc with spacecraft in flight. Recently declassified U.S. military records show that the storm caused sea mines off the Vietnamese coast to explode, as well.
Importantly, the August 1972 solar storm happened in between the Apollo 16 and 17 missions to the Moon. Studies show that astronauts en route to the Moon, and especially astronauts on the surface, could have been badly sickened by the radiation that came with it. This threat remains real if a solar storm of similar severity were to occur during future Lunar missions.
Watchful Protectors
Organizations like NASA and NOAA keep an eye on the Sun, to forecast potential sources of danger. If a solar flare or Coronal Mass Ejection (CME) is on the way, scientists should be able to spot the danger ahead of time so that steps can be taken to reduce the damage. For astronauts going to the Moon, this may be as simple as taking shelter in a special part of their spacecraft.
An animated gif of a Coronal Mass Ejection (CME) erupting from the surface of the Sun in September 2024. If a CME like this was aimed at the Moon, the intense energy it carried could damage spacecraft electronics and even cause severe radiation sickness in astronauts. NOAA/NASA NOAA’s Space Weather Follow-On (SWFO) program sustains their space weather observations and measurements. NOAA’s CCOR-1 flew on the GOES-19 spacecraft and provides crucial near-real-time CME data. The CCOR-2 instrument will fly on SWFO-L1. Other missions include SOHO, a long-running collaboration between NASA and the European Space Agency, and HERMES, a NASA heliophysics instrument intended for the Lunar Gateway that will orbit the Moon.
NASA’s Moon to Mars Space Weather Analysis Office (M2M SWAO) also conducts real-time space weather assessments. These support new capabilities for understanding space weather impacts on NASA exploration activities, including on the Moon.
The Moon as a Laboratory
A big part of the reason we want to go back to the Moon is the amazing level of information we can learn about the history of the Solar System. “Any object in our solar system doesn’t just exist in isolation,” explains Prabal Saxena, a Research Space Scientist in the Planetary Geology, Geophysics & Geochemistry Lab at NASA’s Goddard Space Flight Center. “It is constantly interacting with meteorites and meteors. That’s why you see a lot of the impact creators on the Moon. But it is also constantly interacting with the Sun.” This can come from the solar wind, CMEs, and other forms of solar energy hitting the Moon’s barren surface.
Pictured is the Lunar Swirl Reiner Gamma, a geological feature on the surface of the moon. In areas that are magnetically protected, the ground stays relatively bright. Just outside of the shielded regions, radiation-induced chemical reactions darken the landscape, effectively “sunburning” the lunar surface. NASA/GSFC/Arizona State University Saxena points out that the Moon’s relative lack of a magnetosphere means that Lunar surface material effectively traps evidence of the past habits of the Sun. “A lot of the energetic particles that we would otherwise see deflected by Earth’s magnetosphere and atmosphere are impacting the surface of the Moon. So you can actually trace back what the history of the Sun might be.”
He compares this to scientists taking ice cores to get a glimpse into Earth’s atmospheric history. With everything from evidence of the prehistoric solar atmosphere to information on how the Sun affects water on the lunar surface locked in rocks left largely untouched for millions of years, it is clear why NASA wants to go back and have another look around.
Going Back
But it is still important to keep an eye on the potential dangers to explorers both metallic and organic. In an interview, Lennard Fisk, former NASA Associate Administrator for Space Science and Applications, described a conversation he had with Neil Armstrong. More than anything else during Apollo 11, Armstrong was afraid of a solar flare. He knew he could depend on his spacecraft and crewmates. But space weather was an uncontrollable variable.
We had a different understanding of space weather in 1969. Space radiation, including the solar wind, was a new discovery back then. But research done in those early days helped make breakthroughs still paying off today, and we are building upon these discoveries with new missions that continue to advance our knowledge of the Sun and the rest of our solar system.
