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.

On Aug. 30, 1984, space shuttle Discovery lifted off on the STS-41D mission, joining NASA’s fleet as the third space qualified orbiter. The newest shuttle incorporated newer technologies making it significantly lighter than its two predecessors. Discovery lofted the heaviest payload up to that time in shuttle history. The six-person crew included five NASA astronauts and the first commercial payload specialist. During the six-day mission, the crew deployed a then-record three commercial satellites, tested an experimental solar array, and ran a commercial biotechnology experiment. The astronauts recorded many of the activities using a large format film camera, the scenes later incorporated into a motion picture for public engagement. The mission marked the first of Discovery’s 39 trips to space, the most of any orbiter.

Space shuttle Discovery, the third space-qualified orbiter in NASA’s fleet and named after several historical ships of exploration, incorporated manufacturing lessons learned from the first orbiters. In addition, through the use of more advanced materials, the new vehicle weighed nearly 8,000 pounds less than its sister ship Columbia and 700 pounds less than Challenger. Discovery rolled out of Rockwell International’s plant in Palmdale, California, on Oct. 16, 1983. Five of the six crew members assigned to its first flight attended the ceremony. Workers trucked Discovery overland from Palmdale to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base (AFB), where they mounted it atop a Shuttle Carrier Aircraft (SCA), a modified Boeing 747, for the transcontinental ferry flight to NASA’s Kennedy Space Center (KSC) in Florida. Discovery arrived at KSC on Nov. 9 following a two-day stopover at Vandenberg Air Force, now Space Force Base, in California.

Walker, back row left, and Judith A. Resnik. Right: Payloads installed in Discovery’s payload bay for the STS-41D mission include OAST-1, top, SBS-4, Telstar 3C, and Leasat-2.
To fly Discovery’s first flight, originally designated STS-12 and later renamed STS-41D, in February 1983 NASA assigned Commander Henry W. Hartsfield, a veteran of STS-4, and first-time flyers Pilot Michael L. Coats, and Mission Specialists R. Michael Mullane, Steven A. Hawley, and Judith A. Resnik, all from the 1978 class of astronauts and making their first spaceflights. In May 1983, NASA announced the addition of Charles D. Walker, an employee of the McDonnell Douglas Corporation, to the crew, flying as the first commercial payload specialist. He would operate the company’s Continuous Flow Electrophoresis System (CFES) experiment. The mission’s primary payloads included the Leasat-1 (formerly known as Syncom IV-1) commercial communications satellite and OAST-1, three experiments from NASA’s Office of Aeronautics and Space Technology, including the Solar Array Experiment, a 105-foot long lightweight deployable and retractable solar array. Following the June 1984 launch abort, NASA canceled the STS-41F mission, combining its payloads with STS-41D’s, resulting in three communications satellites – SBS-4 for Small Business Systems, Telstar 3C for AT&T, and Leasat 2 (Syncom IV-2) for the U.S. Navy – launching on the flight. The combined cargo weighed 41,184 pounds, the heaviest of the shuttle program up to that time. A large format IMAX® camera, making its second trip into space aboard the shuttle, flew in the middeck to film scenes inside the orbiter and out the windows.
Left: First rollout of Discovery from the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. Right: The June 26 launch abort.
The day after its arrival at KSC, workers towed Discovery to the Orbiter Processing Facility (OPF) to begin preparing it for its first space flight. They towed it to the Vehicle Assembly Building (VAB) on May 12, 1984, for mating with its External Tank (ET) and Solid Rocket Boosters (SRBs). The completed stack rolled out to Launch Pad 39A a week later. On June 2, engineers successfully completed an 18-second Flight Readiness Firing of Discovery’s main engines. Post test inspections revealed a debonding of a thermal shield in main engine number 1’s combustion chamber, requiring its replacement at the pad. The work pushed the planned launch date back three days to June 25. The failure of the shuttle’s backup General Purpose Computer (GPC) delayed the launch by one day. The June 26 launch attempt ended just four seconds before liftoff, after two of the main engines had already ignited. The GPC detected that the third engine had not started and shut all three down. It marked the first time a human spaceflight launch experienced an abort after the start of its engines since Gemini VI in October 1965. The abort necessitated a rollback to the VAB on July 14 where workers demated Discovery from the ET and SRBs. Engineers replaced the faulty engine, and Discovery rolled back out to the launch pad on Aug. 9 for another launch attempt. The six-person crew participated in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the actual countdown to launch, on Aug. 15. A software issue delayed the first launch attempt on Aug. 29 by one day.

Finally, on Aug. 30, 1984, Discovery roared off its launch pad on a pillar of flame and within 8 and a half minutes entered orbit around the Earth. The crew got down to work and on the first day Mullane and Hawley deployed the SBS-4 satellite. On the second day in space, they deployed Leasat, the first satellite designed specifically to be launched from the shuttle. On the third day, they deployed the Telstar satellite, completing the satellite delivery objectives of the mission. Resnik deployed the OAST-1 solar array to 70% of its length to conduct dynamic tests on the structure. On the fourth day, she deployed the solar array to its full length and successfully retracted it, completing all objectives for that experiment.

Walker remained busy with the CFES, operating the unit for about 100 hours, and although the experiment experienced two unexpected shutdowns, he processed about 85% of the planned samples. Hartsfield and Coats exposed two magazines and six rolls of IMAX® film, recording OAST-1 and satellite deployments as well as in-cabin crew activities. Clips from the mission appear in the 1985 IMAX® film “The Dream is Alive.” On the mission’s fifth day, concern arose over the formation of ice on the orbiter’s waste dump nozzle. The next day, Hartsfield used the shuttle’s robotic arm to dislodge the large chunk of ice.

On Sep. 5, the astronauts closed Discovery’s payload bay doors in preparation for reentry. They fired the shuttle’s Orbital Maneuvering System engines to slow their velocity and begin their descent back to Earth. Hartsfield guided Discovery to a smooth landing at Edwards AFB in California, completing a flight of 6 days and 56 minutes. The crew had traveled 2.5 million miles and orbited the Earth 97 times.

By Sept. 10, workers had returned Discovery to KSC to prepare it for its next mission, STS-51A, in November 1984. During its lifetime, Discovery flew a fleet leading 39 missions, making its final trip to space in February 2011. It flew both return to flight missions, STS-26 in 1988 and STS-114 in 2005. It launched the Hubble Space Telescope in 1990 and flew two of the missions to service the facility. Discovery flew two mission to Mir, docking once. It completed the first docking to the International Space Station in 1999 and flew a total of 13 assembly and resupply missions to the orbiting lab. By its last mission, Discovery had traveled 149 million miles, completed 5,830 orbits of the Earth, and spent a cumulative 365 days in space in the span of 27 years. The public can view Discovery on display at the National Air and Space Museum’s Stephen F. Udvar-Hazy Center in Chantilly, Virginia.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Student Launch, a STEM competition, officially kicks off its 25th anniversary with the 2025 handbook. By Wayne Smith
NASA’s Student Launch competition kicks off its 25th year with the release of the 2025 handbook, detailing how teams can submit proposals by Wednesday, Sept. 11, for the event scheduled next spring near NASA’s Marshall Space Flight Center in Huntsville, Alabama.
Student Launch is an annual competition challenging middle school, high school, and college students to design, build, test, and launch a high-powered amateur rocket with a scientific or engineering payload. After a team is selected, they must meet documentation milestones and undergo detailed reviews throughout the school year.
Each year, NASA updates the university payload challenge to reflect current scientific and exploration missions. For the 2025 season, the payload challenge will again take inspiration from the Artemis missions, which seek to land the first woman and first person of color on the Moon.
As Student Launch celebrates its 25th anniversary, the payload challenge will include “reports” from STEMnauts, non-living objects representing astronauts. The 2024 challenge tasked teams with safely deploying a lander mid-air for a group of four STEMnauts using metrics to support a survivable landing. The lander had to be deployed without a parachute and had a minimum weight limit of five pounds.
“This year, we’re shifting the focus to communications for the payload challenge,” said John Eckhart, technical coordinator for Student Launch at Marshall. “The STEMnaut ‘crew’ must relay real-time data to the student team’s mission control. This helps connect Student Launch with the Artemis missions when NASA lands astronauts on the Moon.”
Thousands of students participated in the 2024 Student Launch competition – making up 70 teams representing 24 states and Puerto Rico. Teams launched their rockets to an altitude between 4,000 and 6,000 feet, while attempting to make a successful landing and executing the payload mission. The University of Notre Dame was the overall winner of the 2024 event, which culminated with a launch day open to the public.
Student Launch began in 2000 when former Marshall Director Art Stephenson started a student rocket competition at the center. It started with just two universities in Huntsville competing – Alabama A&M University and the University of Alabama in Huntsville – but has continued to soar. Since its inception, thousands of students have participated in the agency’s STEM competition, with many going on to a career with NASA.
“This remarkable journey, spanning a quarter of a century, has been a testament to the dedication, ingenuity, and passion of countless students, educators, and mentors who have contributed to the program’s success,” Eckhart said. “NASA Student Launch has been at the forefront of experiential education, providing students from middle school through university with unparalleled opportunities to engage in real-world engineering and scientific research. The program’s core mission – to inspire and cultivate the next generation of aerospace professionals and space explorers – has not only been met but exceeded in ways we could have only dreamed of.”
To encourage students to pursue degrees and careers in STEM (science, technology, engineering, and math), Marshall’s Office of STEM Engagement hosts Student Launch, providing them with real-world experiences. Student Launch is one of NASA’s nine Artemis Student Challenges – a variety of activities that expose students to the knowledge and technology required to achieve the goals of Artemis.
In addition to the NASA Office of STEM Engagement’s Next Generation STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.
“These bright students rise to a nine-month challenge for Student Launch that tests their skills in engineering, design, and teamwork,” said Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region. “They are the Artemis Generation, the future scientists, engineers, and innovators who will lead us into the future of space exploration.”
