The uncrewed Boeing Starliner spacecraft is less than two minutes from landing on U.S. soil after spending three months at the International Space Station. Starliner is the first American-made orbital crew capsule designed to perform a ground landing as a reusable spacecraft.
The base heat shield separated from the spacecraft to allow the six airbags to inflate and brace for a ground landing. The three main parachutes are also slowing down the uncrewed capsule.
The airbags are filled with nitrogen to cushion Starliner’s landing at White Sands Space Harbor in New Mexico. The NASA and Boeing landing and recovery team is stationed at a holding zone near the landing site. After landing, technicians will use equipment to “sniff” the spacecraft for any lingering hypergolic fluids before approaching Starliner, opening the hatch, and unloading time-critical cargo. The spacecraft will then be transported to Boeing facilities at NASA’s Kennedy Space Center in Florida.

NASA’s coverage continues as Boeing’s uncrewed Starliner spacecraft reaches the final stages of landing.
Around 30,000 feet after atmospheric re-entry, the forward heat shield separated from the spacecraft and the drogue parachutes inflated to help slow down the uncrewed capsule.
About 45 seconds later, at around 8,000 feet, the drogue parachutes separated to make way for three larger main parachutes to deploy, slow down Starliner to 4 miles per hour, and allow an airbag-assisted landing.
Soon, the base heat shield will jettison to expose six airbags that will inflate to assist in a soft landing at White Sands Space Harbor in New Mexico in just a few minutes at 12 a.m. EDT, Saturday, Sept. 7.

NASA’s coverage continues on NASA+, the NASA app, and YouTube, and the agency’s website as Boeing’s uncrewed Starliner spacecraft begins entry interface 400,000 feet above Earth.
As the hottest part of re-entry, the spacecraft’s heat shield will reach 3,000 degrees Fahrenheit as it enters the atmosphere.
Starliner is equipped with an ablative heat shield containing a layer of plastic resin that will heat up to gas and carry the heat away from the crew capsule through convection. This process helps keep the temperature inside the capsule around 70 degrees Fahrenheit. Similar heat shields were used on Mercury, Gemini, and Apollo spacecrafts.
The spacecraft is expected to land at approximately 12 a.m. Saturday, Sept. 7, at White Sands Space Harbor in New Mexico.

NASA will return Boeing’s Starliner to Earth without astronauts Butch Wilmore and Suni Williams aboard the spacecraft, the agency announced Saturday during a news conference. The uncrewed return allows NASA and Boeing to continue gathering testing data on Starliner during its upcoming flight home, while also not accepting more risk than necessary for its crew. The news conference is available here.
Wilmore and Williams, who flew to the International Space Station in June aboard NASA’s Boeing Crew Flight Test, have been busy supporting station research, maintenance, and Starliner system testing and data analysis, among other activities.
“Spaceflight is risky, even at its safest and most routine. A test flight, by nature, is neither safe, nor routine. The decision to keep Butch and Suni aboard the International Space Station and bring Boeing’s Starliner home uncrewed is the result of our commitment to safety: our core value and our North Star,” said NASA Administrator Bill Nelson. “I’m grateful to both the NASA and Boeing teams for all their incredible and detailed work.”
Wilmore and Williams will continue their work formally as part of the Expedition 71/72 crew through February 2025. They will fly home aboard a Dragon spacecraft with two other crew members assigned to the agency’s SpaceX Crew-9 mission. Starliner is expected to depart from the space station and make a safe, controlled autonomous re-entry and landing in early September.
NASA and Boeing identified helium leaks and experienced issues with the spacecraft reaction control thrusters on June 6 as Starliner approached the space station. Since then, engineering teams have completed a significant amount of work, including reviewing a collection of data, conducting flight and ground testing, hosting independent reviews with agency propulsion experts, and developing various return contingency plans. The uncertainty and lack of expert concurrence does not meet the agency’s safety and performance requirements for human spaceflight, thus prompting NASA leadership to move the astronauts to the Crew-9 mission.
“Decisions like this are never easy, but I want to commend our NASA and Boeing teams for their thorough analysis, transparent discussions, and focus on safety during the Crew Flight Test,” said Ken Bowersox, associate administrator for NASA’s Space Operations Mission Directorate. “We’ve learned a lot about the spacecraft during its journey to the station and its docked operations. We also will continue to gather more data about Starliner during the uncrewed return and improve the system for future flights to the space station.”
Starliner is designed to operate autonomously and previously completed two uncrewed flights. NASA and Boeing will work together to adjust end-of-mission planning and Starliner’s systems to set up for the uncrewed return in the coming weeks. Starliner must return to Earth before the Crew-9 mission launches to ensure a docking port is available on station.
“Starliner is a very capable spacecraft and, ultimately, this comes down to needing a higher level of certainty to perform a crewed return,” said Steve Stich, manager of NASA’s Commercial Crew Program. “The NASA and Boeing teams have completed a tremendous amount of testing and analysis, and this flight test is providing critical information on Starliner’s performance in space. Our efforts will help prepare for the uncrewed return and will greatly benefit future corrective actions for the spacecraft.”
NASA’s Commercial Crew Program requires spacecraft fly a crewed test flight to prove the system is ready for regular flights to and from the space station. Following Starliner’s return, the agency will review all mission-related data to inform what additional actions are required to meet NASA’s certification requirements.
The agency’s SpaceX Crew-9 mission, originally slated with four crew members, will launch no earlier than Tuesday, Sept. 24. The agency will share more information about the Crew-9 complement when details are finalized.
NASA and SpaceX currently are working several items before launch, including reconfiguring seats on the Crew-9 Dragon, and adjusting the manifest to carry additional cargo, personal effects, and Dragon-specific spacesuits for Wilmore and Williams. In addition, NASA and SpaceX now will use new facilities at Space Launch Complex-40 at Cape Canaveral Space Force Station in Florida to launch Crew-9, which provides increased operational flexibility around NASA’s planned Europa Clipper launch.
The Crew-9 mission will be the ninth rotational mission to the space station under NASA’s Commercial Crew Program, which works with the American aerospace industry to meet the goal of safe, reliable, and cost-effective transportation to and from the orbital outpost on American-made rockets and spacecraft launching from American soil.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon where the agency is preparing for future human exploration of Mars.

NASA and Boeing leadership provided an update on Starliner’s Crew Flight Test during a news conference Thursday. The integrated Starliner team continues to assess the spacecraft’s propulsion system performance and complete other tasks before scheduling its undocking from the International Space Station and return to Earth. Watch the full replay of the news conference.
Engineering teams from NASA and Boeing recently wrapped up ground hot fire testing of a Starliner reaction control system thruster at the agency’s White Sands Test Facility in New Mexico. The test series involved firing the engine under conditions like those the spacecraft experienced during its approach to the space station. The tests also included various stress-case scenarios to simulate the conditions expected during Starliner’s undocking and deorbit burn, which will position the spacecraft for landing in the southwestern United States. Teams are in the process of taking apart this thruster to conduct physical inspections. Initial findings show degraded thruster performance, which aligns with what has been observed in orbit.
Additionally, NASA and Boeing will conduct a second docked hot fire test over the weekend to demonstrate the spacecraft’s thruster performance. The first docked hot fire test occurred on June 15. The upcoming test will allow checks of the helium leaks while also verifying the thrusters are operating as expected.
NASA plans to hold an agency-level readiness review no earlier than next week. Following the review, mission leadership will finalize the plan for a normal return to Earth and select a targeted undocking date for Starliner. NASA also plans to host a televised briefing with agency and Boeing leadership following the review. More news conference details will be shared when available.
NASA astronauts Butch Wilmore and Suni Williams continue to provide additional crew time and valuable contributions aboard the space station, assisting with science investigations and helping ground teams collect critical data for post-certification, long-duration Starliner flights to the orbiting complex.
