Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 quiet supersonic research aircraft sits on the ramp at sunrise before ground tests at Lockheed Martin’s Skunk Works facility in Palmdale, California, on July 18, 2025. The X-59 is the centerpiece of NASA’s Quesst mission to demonstrate quiet supersonic flight and the aircraft is scheduled to make its first flight later this year.Lockheed Martin Corporation As we honor the legacy of aviation pioneers this National Aviation Day, NASA’s X-59 is preparing to push the boundaries of what’s possible in air travel. The quiet supersonic aircraft’s historic first flight is on the horizon, with final ground tests about to begin.
Following completion of low-speed taxi tests in July 2025 in Palmdale, California, medium- and high-speed taxi tests mark the final steps before the aircraft takes to the skies for the first time. The taxi tests will focus on how the aircraft handles at higher ground speeds, including braking, steering, stability, and sensor performance. The X-59 team will also assess how well the visibility systems work since the cockpit has no forward-facing window.
The X-59’s initial flight will kick off a first phase of flight testing focused on verifying the aircraft’s airworthiness and safety. The X-59 will reach speeds of approximately 240 mph at an altitude of about 12,000 feet. The roughly one-hour flight will depart from Palmdale and land at NASA’s Armstrong Flight Research Center in Edwards, California.
During the flight, the X-59 team will evaluate several critical systems, including engine performance, stabilization, instrumentation, autopilot, control systems, and air data performance. These checks will ensure the aircraft is ready for future flight tests, where it will fly faster and higher to evaluate performance and safety, ultimately leading to future phases of the mission.
The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight by reducing the loud sonic boom to a quieter “thump.” Proving the X-plane’s airworthiness is the first step on the path to gathering data in support of the mission. The flight data will help inform U.S. and international regulators as they consider new noise standards for supersonic commercial flight over land.

5 Min Read NASA, Army National Guard Partner on Flight Training for Moon Landing
By Corinne Beckinger
When Artemis astronauts land on the Moon’s South Pole in a commercial human landing system, they will encounter a landscape pockmarked with deep craters, sloped connecting ridges, and harsh lighting conditions. The Moon’s lack of contrast, combined with its rolling terrain, will also pose a challenge, making it difficult for astronauts to overcome visual illusions on the lunar surface.
NASA astronaut Bob Hines (left) and Colorado Army National Guard HAATS instructor Ethan Jacobs practice landing procedures in the Rocky Mountains of Colorado in April 2025. Depending on the season, the snowy or dusty conditions can cause visual obstruction. Lunar dust can cause similar visual impairment during future crewed missions. In the mountains of northern Colorado, NASA and the U.S. Army National Guard are using military helicopters to develop a foundational lunar landersimulated flight training course to help astronauts practice flight and landing procedures for the Moon.
For decades, military helicopter pilots have trained at the HAATS (High-Altitude Army National Guard Aviation Training Site) in Gypsum, Colorado. In 2021, NASA and the Colorado Army National Guard began working together to develop a course specifically for the next generation of lunar explorers.
That NASA-specific course is scheduled to be finalized in August 2025, marking an important milestone for Artemis crewed landings training efforts.
“NASA is using a three-pronged approach with motion-based simulation, in-flight lunar landing analog training, and in-flight lunar simulation to build out its foundational training for Artemis Moon landings,” said NASA astronaut Doug Wheelock, who helped coordinate the training program. “Helicopters at or above 10,000 feet are not really efficient in the thin air, forcing us into operating with very thin power margins similar to the Apollo astronauts having to manage energy and momentum to land safely. The operations along with the terrain at the HAATS course in Colorado’s Rocky Mountains provide a valuable, real-world opportunity for Artemis astronauts to practice flying and landing in conditions similar to maneuvering a lander in the lunar environment.”
NASA astronaut Raja Chari participates in the HAATS course in April 2025. Since 2021, 22 NASA astronauts and one ESA (European Space Agency) astronaut have participated and evaluated the course based on functionality and Artemis mission needs. NASA/Laura Kiker NASA astronaut Raja Chari participates in the HAATS course in April 2025. Since 2021, 22 NASA astronauts and one ESA (European Space Agency) astronaut have participated and evaluated the course based on functionality and Artemis mission needs. NASA/Corinne Beckinger NASA’s human landing systems that will safely transport astronauts to and from the Moon’s surface will be provided by SpaceX and Blue Origin.
NASA’s Artemis III mission will build on earlier test flights and add new capabilities, including SpaceX’s Starship Human Landing System and advanced spacesuits, to send the first astronauts to explore the lunar South Pole and prepare humanity to go to Mars.
While each industry provider is responsible for training Artemis astronauts on its specific lander, NASA is establishing foundational training to help prepare astronauts for crewed flights.
Flight training opportunities like this are vital to mission success and crew safety.”
Doug Wheelock
NASA Astronaut
“Over the last few years, NASA and the Army National Guard have worked closely to evaluate training procedures and landing zone areas, incorporating accounts from Apollo astronauts,” Wheelock said. “During training flights at HAATS, astronauts can experience the visual illusions, cross-cockpit communication, and degraded visibility they may experience navigating to their landing zone near the lunar south pole. Flight training opportunities like this are vital to mission success and crew safety.”
Paired with trained instructors from the Army National Guard, astronauts fly to mountaintops and valleys in a range of aircraft, including LUH-72 Lakotas, CH-47 Chinooks, and UH-60 Black Hawks.
While one astronaut pilots the aircraft, an astronaut in the back charts the landing area, marking key landmarks, identifying potential hazards, and helping to track the flight path. Throughout the week-long course, the landing zones and situations become more challenging, allowing astronauts to experience team dynamics and practice communication skills they will need to land on the Moon.
“Our full-time Colorado Army National Guard pilots have thousands of flight hours navigating the Rocky Mountains at altitudes ranging from 6,500 to 14,200 feet, and we are reaching new heights by providing realistic and relevant training with NASA for Artemis,” said first sergeant Joshua Smith of the HAATS program. “Our Colorado Army National Guard pilots may not fly around the Moon, but we wear our motto, de monitbus ad astra — from the mountains to the stars — with pride.”
Fast Facts
On the Moon’s South Pole, the Sun is never more than 1.5 degrees above or below the horizon. With the Sun at such a low angle and with only a thin exosphere, shadows are stark, and astronauts may find it difficult to determine distances and heights.
The Moon’s atmosphere is extremely thin, with few particles, and is called an exosphere. The Moon’s exosphere is thin enough to glow in sunlight, which has been observed by spacecraft and some of the Apollo astronauts. The Moon’s surface is challenging to land on. There are inactive volcanoes, bounders, large basins, craters, and cracks in the Moon’s crust, caused by the Earth’s gravity tugging on the Moon. Moon dust can also obscure the view from the windows of a commercial human landing system, and affect sensors that relay important information, such as altitude and velocity, to astronauts. 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.

This is the 23rd spacecraft built to deliver goods to the International Space Station. In March, NASA and Northrop Grumman moved up the company’s Commercial Resupply Services-23 mission to September following damage to the Cygnus Pressurized Cargo Module during shipping for the company’s Commercial Resupply Services-22 flight.
Each resupply mission to the station delivers scientific investigations in the areas of biology and biotechnology, Earth and space science, physical sciences, and technology development and demonstrations. Cargo resupply from U.S. companies ensures a national capability to deliver scientific research to the space station, increasing NASA’s ability to conduct new investigations aboard humanity’s laboratory in space.
In addition to food, supplies, and equipment for the crew, Cygnus will deliver research, including materials to produce semiconductor crystals in space and equipment to develop improvements for cryogenic fuel tanks. Cygnus also will deliver a specialized UV light system to prevent biofilm growth and supplies to produce pharmaceutical crystals that could treat cancer and other diseases.
The International Space Station is a convergence of science, technology, and human innovation that enables research not possible on Earth. For almost 25 years, humans have continuously lived and worked aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies that enable us to prepare for human exploration of the Moon and Mars.
