Their learning experience is a collaboration between aircraft noise researchers from NASA’s Glenn Research Center in Cleveland and educators from the University of Notre Dame’s Turbomachinery Laboratory. The collaboration aims to encourage students’ interest in science, technology, engineering, and math (STEM) careers.
Recently, Notre Dame hosted students from The Portage School of Leaders High School and a team from NASA Glenn to see the Advanced Noise Control Fan operate in an outdoor setting. The fan is a NASA-owned test rig that has been configured to enable the study of a quieter aircraft engine technology. Known as the open rotor fan concept, the configuration involves an engine fan without a cover. Ground microphones were used during the test operated by Notre Dame to evaluate the radiated sound as the open rotor fan spun at various speeds.

It provides a hands-on learning laboratory for students in STEM.Credit: Matt Cashore/University of Notre Dame Students from the high school, which is part of the Career Academy Network of Public Schools, used 3D printers from the school’s facilities to fabricate parts for the open rotor test fan. The parts, known as stator blades, help direct and control airflow, ensuring smooth operation of the large, exposed fan blades that are the defining feature of an open fan engine design.
“It was beyond words,” said Rebecca Anderson, a junior from the high school. “The part I enjoyed most was when they got the fan running. It was really impressive to see how quiet it was. I feel like everyone involved in STEM would love to work for NASA, including me.”
NASA researcher Dr. Daniel Sutliff was part of the team from NASA Glenn to spend time mentoring the students.
“This is real-world, hands-on research for them,” Sutliff said. “If airlines are able to use technologies to make flight quieter and cleaner, passengers will have more enjoyable flights.”
The Advanced Noise Control Fan is on loan to Notre Dame from NASA through a Space Act Agreement. The fan research is supported by NASA’s Advanced Air Transport Technology project and its Efficient Quiet Integrated Propulsors technical challenge.

A rendering of Firefly’s Blue Ghost lunar lander and a rover developed for the company’s third mission to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative.Credit: Firefly Aerospace NASA continues to advance its campaign to explore more of the Moon than ever before, awarding Firefly Aerospace $179 million to deliver six experiments to the lunar surface. This fourth task order for Firefly will target landing in the Gruithuisen Domes on the near side of the Moon in 2028.
As part of the agency’s broader Artemis campaign, Firefly will deliver a group of science experiments and technology demonstrations under NASA’s CLPS initiative, or Commercial Lunar Payload Services, to these lunar domes, an area of ancient lava flows, to better understand planetary processes and evolution. Through CLPS, NASA is furthering our understanding of the Moon’s environment and helping prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach.
“The CLPS initiative carries out U.S. scientific and technical studies on the surface of the Moon by robot explorers. As NASA prepares for future human exploration of the Moon, the CLPS initiative continues to support a growing lunar economy with American companies,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “Understanding the formation of the Gruithuisen Domes, as well as the ancient lava flows surrounding the landing site, will help the U.S. answer important questions about the lunar surface.”
Firefly’s first lunar delivery is scheduled to launch no earlier than mid-January 2025 and will land near a volcanic feature called Mons Latreille within Mare Crisium, on the northeast quadrant of the Moon’s near side. Firefly’s second lunar mission includes two task orders: a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side and a delivery of a lunar orbital calibration source, scheduled in 2026.
This new delivery in 2028 will send payloads to the Gruithuisen Domes and the nearby Sinus Viscositatus. The Gruithuisen Domes have long been suspected to be formed by a magma rich in silica, similar in composition to granite. Granitic rocks form easily on Earth due to plate tectonics and oceans of water. The Moon lacks these key ingredients, so lunar scientists have been left to wonder how these domes formed and evolved over time. For the first time, as part of this task order, NASA also has contracted to provide “mobility,” or roving, for some of the scientific instruments on the lunar surface after landing. This will enable new types of U.S. scientific investigations from CLPS.
“Firefly will deliver six instruments to understand the landing site and surrounding vicinity,” said Chris Culbert, manager of the CLPS initiative at NASA’s Johnson Space Center in Houston. “These instruments will study geologic processes and lunar regolith, test solar cells, and characterize the neutron radiation environment, supplying invaluable information as NASA works to establish a long-term presence on the Moon.”
The instruments, collectively expected to be about 215 pounds (97 kilograms) in mass, include:
Lunar Vulkan Imaging and Spectroscopy Explorer, which consists of two stationary and three mobile instruments, will study rocks and regoliths on the summit of one of the domes to determine their origin and better understand geologic processes of early planetary bodies. The principal investigator is Dr. Kerri Donaldson Hanna of the University of Central Florida, Orlando. Heimdall is a flexible camera system that will be used to take pictures of the landing site from above the horizon to the ground directly below the lander. The principal investigator is Dr. R. Aileen Yingst of the Planetary Science Institute, Tucson, Arizona. Sample Acquisition, Morphology Filtering, and Probing of Lunar Regolith is a robotic arm that will collect samples of lunar regolith and use a robotic scoop to filter and isolate particles of different sizes. The sampling technology will use a flight spare from the Mars Exploration Rover project. The principal investigator is Sean Dougherty of Maxar Technologies, Westminster, Colorado. Low-frequency Radio Observations from the Near Side Lunar Surface is designed to observe the Moon’s surface environment in radio frequencies, to determine whether natural and human-generated activity near the surface interferes with science. The project is headed up by Natchimuthuk Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Photovoltaic Investigation on the Lunar Surface will carry a set of the latest solar cells for a technology demonstration of light-to-electricity power conversion for future missions. The experiment will also collect data on the electrical charging environment of the lunar surface using a small array of solar cells. The principal investigator is Jeremiah McNatt from NASA’s Glenn Research Center in Cleveland. Neutron Measurements at the Lunar Surface is a neutron spectrometer that will characterize the surface neutron radiation environment, monitor hydrogen, and provide constraints on elemental composition. The principal investigator is Dr. Heidi Haviland of NASA’s Marshall Spaceflight Center in Huntsville, Alabama. Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry. Two upcoming CLPS flights scheduled to launch in early 2025 will deliver NASA payloads to the Moon’s near side and south polar region, respectively.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Orion Environmental Test Article photographed inside the Thermal Vacuum Chamber on April 11, 2024, in the Space Environments Complex at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio. Credit: NASA/Quentin Schwinn Making the voyage 1.4 million miles around the Moon and back — the farthest a spacecraft built for humans has ever gone — the Orion spacecraft has faced a battery of tests over the years. Though Orion successfully proved its capabilities in the harsh environment of space during the Artemis I mission, Orion’s evaluation did not end at splashdown.
The crew module, now known as the Orion Environmental Test Article (ETA), returned to NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, in January 2024 and completed an 11-month test campaign necessary for the safety and success of Artemis II, the first crewed mission under NASA’s Artemis campaign.
Engineers and technicians from NASA and Lockheed Martin subjected the test article to the extreme conditions Orion may experience in a launch abort scenario. In the event of an emergency, Orion — and astronauts inside — will jettison away from the SLS (Space Launch System) rocket for a safe landing in the ocean.
Experts at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, conducted a lightning test, which simulates the electromagnetic effects of a lightning strike to the vehicle on the launch pad awaiting liftoff. The Feb. 20, 2024 test proved the grounding path of the vehicle is operating as designed and protecting the vehicle from damage to any of its equipment or systems. Credit: NASA/Quentin Schwinn Experts installed NASA’s Launch Abort System, designed to carry the crew to safety in the event of an emergency during launch or ascent. The Orion test article was subjected to acoustic levels simulating both a nominal ascent and a launch abort scenario. The acoustic test chamber at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, blasted the test article at a volume of almost 164 decibels on Sept. 9, 2024. Credit: NASA/Jordan Salkin On Nov. 11, 2024, experts successfully at NASA’s Neil Armstrong Test Facility completed the docking mechanism jettison test, designed to connect and disconnect the Orion spacecraft to Gateway, a small space station that will orbit the Moon. They also completed the forward bay cover jettison test on Nov. 23, 2024, which is the last piece that must eject right before parachutes deploy, and successfully tested Orion’s uprighting system. Credit: NASA/Jordan Salkin “This event would be the maximum stress and highest load that any of the systems would see,” said Robert Overy, Orion ETA project manager, NASA’s Glenn Research Center in Cleveland. “We’re taking a proven vehicle from a successful flight and pushing it to its limits. The safety of the astronaut crew depends on this test campaign.”
Experts conducted tests that simulated the noise levels of an abort during launch in addition to the electromagnetic effects of lightning strikes. The test campaign also jettisoned the test article’s docking module and parachute covers, as well as the crew module uprighting system, which consists of five airbags on top of the spacecraft that inflate upon splashdown.
“It’s been a successful test campaign,” Overy said. “The data has matched the prediction models, and everything operated as expected after being subjected to nominal and launch abort acoustic levels. We are still analyzing data, but the preliminary results show the vehicle and facility operated as desired.”
On. Nov. 23, 2024, after subjecting the Orion test article to launch abort-level acoustics, experts tested the functionality of the forward bay cover, which is the last piece that must eject before parachutes deploy. Credit: NASA/Jordan Salkin and Quentin Schwinn Testing Orion at such high acoustic levels was a major milestone for Artemis. The Reverberant Acoustic Test Facility, the world’s most powerful spacecraft acoustic test chamber, was built in 2011 in anticipation of this specific test campaign.
“These tests are absolutely critical because we have to complete all of these tests to say the spacecraft design is safe and we’re ready to fly a crew for the first time on Artemis II,” said Michael See, ETA vehicle manager, Orion Program. “This is the first time we’ve been able to test a spacecraft on the ground in such an extreme abort-level acoustic environment.”

Credit: NASA/Jordan Salkin and Quentin Schwinn Part of NASA Glenn, Armstrong Test Facility is home to the world’s largest and most powerful space environment simulation chambers capable of testing full-sized spacecraft for all the extreme conditions of launch and spaceflight. The facility not only houses an acoustic test chamber, but also a thermal-vacuum chamber and spacecraft vibration system.
“The facility is unique because there’s no other place in the world capable of testing spacecraft like this,” Overy said. “Armstrong Test Facility is a one-stop-shop for all your testing needs to prepare your spacecraft for the severe and challenging journey to and from space.”
Orion’s Round-Trip Journey to Ohio
This is not the first time Orion has been inside the walls of the Space Environments Complex at Armstrong Test Facility. The spacecraft underwent mission-critical testing in 2019, where it was subjected to extreme temperatures and an electromagnetic environment before it launched on Artemis I in 2022.
“I remember when it first arrived, the gravity of its importance really hit home,” said Joshua Pawlak, test manager, NASA Glenn. “I thought to myself, on future Artemis missions, astronauts will be inside Orion heading to the Moon, and they’ll be depending on it for survival.”
Pawlak was a mechanical test engineer when Orion made its first trip to the Sandusky facility. He participated in planning and coordinating testing of the vehicle and trained personnel. He managed the vehicle from the moment it arrived, through testing, and up until it departed for NASA’s Kennedy Space Center in Florida.

Credit: Joshua Pawlak “When it returned, I felt like I had a small part in this really big and exciting thing,” Pawlak said. “Seeing it come back blackened and scarred from the harsh environment of space was incredible. Space is not a friendly space, and I felt proud knowing that if there were astronauts on that vehicle, they would have survived.
After the Orion test article departs from Glenn, it will head to Kennedy for additional testing.
“When Artemis II launches and those astronauts are sitting on board, I’ll know that I did everything I could to ensure the vehicle is ready for them and going to perform as expected,” Pawlak said. “That’s why I do what I do.”

On Thursday, Dec. 5, 2024, a team returns the Artemis II Orion spacecraft to the Final Assembly and Test cell from a vacuum chamber inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida where it underwent vacuum testing. NASA/Eric Hernandez NASA’s Orion spacecraft for the Artemis II test flight returned to the Final Assembly and System Testing (FAST) cell following completion of the second round of vacuum chamber testing on Dec. 5 inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida.
After returning to the FAST cell, the four main batteries – which supply power to many Orion systems – were installed in the crew module. The batteries returned to NASA Kennedy from their supplier, EaglePicher Technologies, earlier this month. Solar array wings will also be installed onto the spacecraft by international partner ESA (European Space Agency) and its contractor Airbus in early 2025.
The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back.
