NASA and Boeing welcomed Starliner back to Earth following the uncrewed spacecraft’s successful landing at 10:01 p.m. MDT Sept. 6, 2024, at the White Sands Space Harbor in New Mexico. Credit: NASA NASA and Boeing safely returned the uncrewed Starliner spacecraft following its landing at 10:01 p.m. MDT Sept. 6 at White Sands Space Harbor in New Mexico, concluding a three-month flight test to the International Space Station.
“I am extremely proud of the work our collective team put into this entire flight test, and we are pleased to see Starliner’s safe return,” said Ken Bowersox, associate administrator, Space Operations Mission Directorate at NASA Headquarters in Washington. “Even though it was necessary to return the spacecraft uncrewed, NASA and Boeing learned an incredible amount about Starliner in the most extreme environment possible. NASA looks forward to our continued work with the Boeing team to proceed toward certification of Starliner for crew rotation missions to the space station.”
The flight on June 5 was the first time astronauts launched aboard the Starliner. It was the third orbital flight of the spacecraft, and its second return from the orbiting laboratory. Starliner now will ship to NASA’s Kennedy Space Center in Florida for inspection and processing.
NASA’s Commercial Crew Program requires a spacecraft to fly a crewed test flight to prove the system is ready for regular flights to and from the orbiting laboratory. Following Starliner’s return, the agency will review all mission-related data.
“We are excited to have Starliner home safely. This was an important test flight for NASA in setting us up for future missions on the Starliner system,” said Steve Stich, manager of NASA’s Commercial Crew Program. “There was a lot of valuable learning that will enable our long-term success. I want to commend the entire team for their hard work and dedication over the past three months.”
NASA astronauts Butch Wilmore and Suni Williams launched on June 5 aboard Starliner for the agency’s Boeing Crewed Flight Test from Cape Canaveral Space Force Station in Florida. On June 6, as Starliner approached the space station, NASA and Boeing identified helium leaks and experienced issues with the spacecraft’s reaction control thrusters. Following weeks of in-space and ground testing, technical interchange meetings, and agency reviews, NASA made the decision to prioritize safety and return Starliner without its crew. Wilmore and Williams will continue their work aboard station as part of the Expedition 71/72 crew, returning in February 2025 with the agency’s SpaceX Crew-9 mission.
The crew flight test is part of NASA’s Commercial Crew Program. The goal of NASA’s Commercial Crew Program is safe, reliable, and cost-effective transportation to and from the International Space Station and low Earth orbit. This already is providing additional research time and has increased the opportunity for discovery aboard humanity’s microgravity testbed, including helping NASA prepare for human exploration of the Moon and Mars.

NASA and Boeing teams work around Boeing’s Starliner spacecraft after it landed at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Boeing’s Orbital Flight Test-2.NASA/Bill Ingalls As NASA and Boeing prepare to return the company’s Starliner spacecraft uncrewed from the International Space Station to Earth, safety and mission success remain as top priorities for the teams. Mission managers will complete a series of operational and weather checks before the spacecraft undocks from the orbital complex.
The Starliner spacecraft is the first American capsule designed to touch down on land, supporting expedited astronaut and cargo recovery on future missions and to aid the company in spacecraft refurbishment. For Starliner missions, NASA and Boeing will use potential landing locations in the White Sands Missile Range, New Mexico; Willcox, Arizona; and Dugway Proving Ground, Utah. Edwards Air Force Base in California also is available as a contingency landing site.
Twenty-four hours before undocking, NASA analyzes weather predictions for the various landing sites. Winds at the selected landing site must be 6 mph (approximately 6 knots) or less when flying with crew, and approximately 13 mph (12 knots) or less when uncrewed. Ground temperatures must be warmer than 15 degrees Fahrenheit, and the cloud ceiling must be at least 1,000 feet. One nautical mile of visibility is required, and the area must be clear of precipitation, thunderstorms, and lightning within approximately a 22-mile (35-kilometer) radius.
When teams proceed with undocking, Starliner will complete a series of departure burns, allowing it to reach its landing site in as little as six hours. A final weather check also occurs before the spacecraft’s deorbit burn. Winds must be at or below 10 mph (9 knots). If winds exceed these limits, teams will waive the deorbit burn, and Starliner will target another landing attempt between 24 and 31 hours later.
Once clear to proceed, Starliner executes its deorbit burn, which lasts approximately 60 seconds, slowing it down enough to re-enter Earth’s atmosphere and committing the spacecraft to its targeted site. Immediately after the deorbit burn, Starliner repositions for service module disposal, which will burn up during re-entry over the southern Pacific Ocean.
Following service module separation, the command module maneuvers into re-entry position. During re-entry, the capsule experiences plasma buildup – reaching temperatures up to 3,000 degrees Fahrenheit – that may interrupt communications with the spacecraft for approximately four minutes.
NASA and Boeing teams work around Boeing’s Starliner spacecraft after it landed at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Boeing’s Orbital Flight Test-2.NASA/Bill Ingalls Once Starliner re-enters Earth’s atmosphere, the forward heatshield – located on the top of the spacecraft – is jettisoned at 30,000 feet, exposing the two drogue and three main parachutes for deployment. The parachutes will continue to slow the spacecraft down as the base heatshield is jettisoned at 3,000 feet, allowing the six landing bags to inflate. At touchdown, the spacecraft is traveling at approximately 4 mph.
NASA and Boeing teams prepare for the landing of Boeing’s Starliner spacecraft at White Sands Missile Range’s Space Harbor, May 25, 2022, in New Mexico for the company’s Orbital Flight Test-2.NASA/Bill Ingalls The NASA and Boeing landing and recovery team is stationed at a holding zone near Starliner’s intended landing site. After landing, a series of five teams move in toward the spacecraft in a sequential order.
The first team to approach the spacecraft is the gold team, using equipment that “sniffs” the capsule for any hypergolic fuels that didn’t fully burn off before re-entry. They also cover the spacecraft’s thrusters. Once given the all-clear, the silver team moves in. This team electrically grounds and stabilizes Starliner before the green team approaches, supplying power and cooling to the crew module since the spacecraft is powered down.

The spacecraft is then transferred to Boeing facilities at NASA’s Kennedy Space Center in Florida for refurbishment ahead of its next flight.
NASA’s Commercial Crew Program is working with the American aerospace industry through a public-private partnership to launch astronauts on American rockets and spacecraft from American soil. The program’s goal is to provide safe, reliable, and cost-effective transportation on space station missions, which will allow for additional research time. The space station remains the springboard to NASA’s next great leap in space exploration, including future missions to the Moon and, eventually, to Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A National Advisory Committee for Aeronautics researcher notes the conditions on the P-39L after its first test run in the Icing Research Tunnel on Sept. 13, 1944. The aircraft was too large to fit in the test section, so it was installed downstream in a larger area of the tunnel. The initial tests analyzed ice buildup on the nose, propeller blades, and antennae. In the summer of 1945, the P-39L was used to demonstrate the effectiveness of a thermal pneumatic boot ice-prevention system and heated propeller blades.Credit: NASA On Sept. 13, 1944, researchers subjected a Bell P-39L Airacobra to frigid temperatures and a freezing water spray in the National Advisory Committee for Aeronautics (NACA)’s new Icing Research Tunnel (IRT) to study inflight ice buildup. Since that first run at the Aircraft Engine Research Laboratory (now NASA’s Glenn Research Center) in Cleveland, the facility has operated on a regular basis for 80 years and remains the oldest and one of the largest icing tunnels in the world.
Water droplets in clouds can freeze on aircraft surfaces in certain atmospheric conditions. Ice buildup on the forward edges of wings and tails causes significant decreases in lift and rapid increases in drag. Ice can also block engine intakes and add weight. NASA has a long tradition of working to understand the conditions that cause icing and developing systems that prevent and remove ice buildup.
The NACA decided to build its new icing tunnel adjacent to the lab’s Altitude Wind Tunnel to take advantage of its powerful cooling equipment and unprecedented refrigeration system. The system, which can reduce air temperature to around –30 degrees Fahrenheit, produces realistic and repeatable icing conditions using a spray nozzle system that creates small, very cold droplets and a drive fan that generates airspeeds up to 374 miles per hour.
View upstream of the Icing Research Tunnel’s 25-foot-diameter drive fan in 1944. The original 12-bladed wooden fan and its 4,100-horsepower motor could produce air speeds up to 300 miles per hour. The motor and fan were replaced in 1987 and 1993, respectively.Credit: NASA Two rudimentary icing tunnels had briefly operated at the NACA’s Langley Memorial Aeronautical Laboratory in Hampton, Virginia, but icing research primarily relied on flight testing. The sophisticated new tunnel in Cleveland offered a safer way to study icing physics, test de-icing systems, and develop icing instrumentation.
During World War II, inlet icing was a key contributor to the heavy losses suffered by C-46s flying supply missions to allied troops in China. In February 1945, a large air scoop from the C-46 Commando was installed in the tunnel, where researchers determined the cause of the issue and redesigned the scoop to prevent freezing water droplets entering. The modifications were later incorporated into the C–46 and Convair C–40.
A National Advisory Committee for Aeronautics engineer experiments with an Icing Research Tunnel water spray system design in September 1949. Researchers used data taken from research flights to determine the proper droplet sizes. The atomizing spray system was perfected in 1950.Credit: NASA Despite these early successes, NACA engineers struggled to improve the facility’s droplet spray system because of a lack of small nozzles able to produce sufficiently small droplets. After years of dogged trial and error, the breakthrough came in 1950 with an 80-nozzle system that produced the uniform microscopic droplets needed to properly simulate a natural icing cloud.
Usage of the IRT increased in the 1950s, and the controlled conditions produced by the facility helped researchers define specific atmospheric conditions that produce icing. The Civil Aeronautics Authority (the precursor to the Federal Aviation Administration) used this data to establish regulations for all-weather aircraft. The facility also contributed to new icing protections for antennae and jet engines and the development of cyclical heating de-icing systems.
The success of the NACA’s icing program, along with the increased use of jet engines – which permitted cruising above the weather – reduced the need for additional icing research. In early 1957, just before the NACA transitioned to NASA, the center’s icing program was terminated. Nonetheless, the IRT remained active throughout the 1960s and 1970s supporting industry testing.
The Icing Research Tunnel is highlighted in this 1973 aerial photograph. The larger Altitude Wind Tunnel (AWT) is located behind it, and the Refrigeration Building that supported both tunnels is immediately to the left of the AWT.Credit: NASA By the mid-1970s, new icing issues were arising due to the increased use of helicopters, regional airliners, and general aviation aircraft. The center held an icing workshop in July 1978 where over 100 icing experts from across the world converged and lobbied for a reinstatement of NASA’s icing research program.
The agency agreed to provide funding to support a small team of researchers and increase operation of the icing facility. In 1982, a deadly icing-related airline crash spurred NASA to bring back a full-fledged icing research program.
Nearly all the tunnel’s major components were subsequently upgraded. Use of the IRT skyrocketed, and there was at least a one-year wait for new tests during this period. In 1988, the facility operated more hours than any year since 1950.
This model was installed in the Icing Research Tunnel in 2023 as part of the Advanced Air Mobility Rotor Icing Evaluation Study, which sought to refine testing of rotating models in the tunnel, validate 3D computational models, and study propeller icing issues.Credit: NASA The facility was used in a complementary way with the Twin Otter aircraft and computer simulation to improve de-icing systems, predictive tools, and instrumentation. IRT testing also accelerated the all-weather certification of the OH-60 Black Hawk helicopter. In the 1990s, the icing program turned its attention to combatting super-cooled large droplets, which can cause ice buildup in areas not protected by leading edge de-icing systems, and tailplane icing, which can cause commuter aircraft to pitch forward.
The IRT was one of the busiest facilities at the center in the 2000s and continues to maintain a steady test schedule today, investigating icing on turbofan engines and propellers, refining testing of rotating models, validating 3D models, and much more. The IRT been used to develop nearly every modern ice protection system, provided key icing environment data to regulatory agencies, and validated leading ice prediction software. After 80 years, it remains a critical tool for sustaining NASA’s leadership in the icing field.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A prototype of the Mini Potable Water Dispenser, currently in development at NASA’s Marshall Space Flight Center, is displayed alongside various food pouches during a demonstration at NASA’s Johnson Space Center. NASA/David DeHoyos NASA engineers are working hard to ensure no astronaut goes hungry on the Artemis IV mission.
When international teams of astronauts live on Gateway, humanity’s first space station to orbit the Moon, they’ll need innovative gadgets like the Mini Potable Water Dispenser. Vaguely resembling a toy water soaker, it manually dispenses water for hygiene bags, to rehydrate food, or simply to drink. It is designed to be compact, lightweight, portable and manual, making it ideal for Gateway’s relatively small size and remote location compared to the International Space Station closer to Earth.
The team at NASA’s Marshall Space Flight Center in Huntsville, Alabama leading the development of the dispenser understands that when it comes to deep space cuisine, the food astronauts eat is so much more than just fuel to keep them alive.
“Food doesn’t just provide body nourishment but also soul nourishment,” said Shaun Glasgow, project manager at Marshall. “So ultimately this device will help provide that little piece of soul nourishment. After a long day, the crew can float back and enjoy some pasta or scrambled eggs, a small sense of normalcy in a place far from home.”
As NASA continues to innovate and push the boundaries of deep space exploration, devices like the compact, lightweight dispenser demonstrate a blend of practicality and ingenuity that will help humanity chart its path to the Moon, Mars, and beyond.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Dash 7 aircraft that will be modified into a hybrid electric research vehicle under NASA’s Electrified Powertrain Flight Demonstration project is seen taking off from Moses Lake, Washington en route to Seattle for a ceremony unveiling its new livery. The aircraft is currently operating with a traditional fuel-based propulsion system but will eventually be modified with a hybrid electric system. NASA / David C. Bowman Parked under the lights inside a hangar in Seattle, a hybrid electric research aircraft from electric motor manufacturer magniX showed off a new look symbolizing its journey toward helping NASA make sustainable aviation a reality.
During a special unveiling ceremony hosted by magniX on Aug. 22, leaders from the company and NASA revealed the aircraft, with its new livery, to the public for the first time at King County International Airport, commonly known as Boeing Field.
The aircraft is a De Havilland Dash 7 that was formerly used for carrying cargo. Working under NASA’s Electrified Powertrain Flight Demonstration (EPFD) project, magniX will modify it to serve as a testbed for hybrid electric aircraft propulsion research.
The company’s goal under EPFD is to demonstrate potential fuel savings and performance boosts with a hybrid electric system for regional aircraft carrying up to 50 passengers. These efforts will help reduce environmental impacts from aviation by lowering greenhouse gas emissions.
This livery recognizes the collaborative effort focused on proving that hybrid electric flight for commercial aircraft is feasible.
“We are a research organization that continues to advance aviation, solve the problems of flight, and lead the community into the future,” said Robert A. Pearce, associate administrator for NASA’s Aeronautics Research Mission Directorate. “Through our EPFD project, we’re taking big steps in partnership to make sure electric aviation is part of the future of commercial flight.”

NASA is collaborating with industry to modify existing planes with new electrified aircraft propulsion systems. These aircraft testbeds will help demonstrate the benefits of hybrid electric propulsion systems in reducing fuel burn and emissions for future commercial aircraft, part of NASA’s broader mission to make air travel more sustainable.
“EPFD is about showing how regional-scale aircraft, through ground and flight tests, can be made more sustainable through electric technology that is available right now,” said Ben Loxton, vice president for magniX’s work on the EPFD project.
Thus far, magniX has focused on developing a battery-powered engine and testing it on the ground to make sure it will be safe for work in the air. The company will now begin transitioning over to a new phase of the project — transforming the Dash 7 into a hybrid electric research vehicle.
“With the recent completion of our preliminary design review and baseline flight tests, this marks a transition to the next phase, and the most exciting phase of the project: the modification of this Dash 7 with our magniX electric powertrain,” Loxton said.
To make this possible, magniX is working with their airframe integrator AeroTEC to help modify and prepare the aircraft for flight tests that will take place out of Moses Lake, Washington. Air Tindi, which supplied the aircraft to magniX for this project, will help with maintenance and support of the aircraft during the testing phases.

In front of the plane is an electric powertrain that magniX will integrate into the current aircraft to build a hybrid electric propulsion system.NASA/David C. Bowman Creating a Hybrid Electric Aircraft
A typical hybrid electric propulsion system combines different sources of energy, such as fuel and electricity, to power an aircraft. For magniX’s demonstration, the modified Dash 7 will feature two electric engines fed by battery packs stored in the cabin, and two gas-powered turboprops.
The work will begin with replacing one of the aircraft’s outer turboprop engines with a new, magni650-kilowatt electric engine – the base of its hybrid electric system. After testing those modifications, magniX will swap out the remaining outer turboprop engine for an additional electric one.
Earlier this year, magniX and NASA marked the milestone completion of successfully testing the battery-powered engine at simulated altitude. Engineers at magniX are continuing ground tests of the aircraft’s electrified systems and components at NASA’s Electric Aircraft Testbed (NEAT) facility in Sandusky, Ohio.
By rigorously testing these new technologies under simulated flight conditions, such as high altitudes and extreme temperatures, researchers can ensure each component operates safely before taking to the skies.
The collaboration between EPFD, NASA, GE Aerospace, and magniX works to advance hybrid electric aircraft propulsion technologies for next-generation commercial aircraft in the mid-2030 timeframe. NASA is working with these companies to conduct two flight demonstrations showcasing different approaches to hybrid electric system design.
Researchers will use data gathered from ground and flight tests to identify and reduce certification gaps, as well as inform the development of new standards and regulations for future electrified aircraft.
“We at NASA are excited about EPFD’s potential to make aviation more sustainable,” Pearce said. “Hybrid electric propulsion on a megawatt scale accelerates U.S. progress toward its goal of net-zero greenhouse gas emissions by 2050, benefitting all who rely on air transportation every day.”
