NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will launch no earlier than Tuesday, Sept. 24, on the agency’s SpaceX Crew-9 mission to the International Space Station. NASA astronauts Zena Cardman and Stephanie Wilson, previously announced as crewmates, are eligible for reassignment on a future mission.
Hague and Gorbunov will fly to the space station as commander and mission specialist, respectively, as part of a two-crew member flight aboard a SpaceX Dragon.
The updated crew complement follows NASA’s decision to return the agency’s Boeing Crew Flight Test uncrewed and launch Crew-9 with two unoccupied seats. NASA astronauts Butch Wilmore and Suni Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.
The decision to fly Hague was made by NASA chief astronaut Joe Acaba at the agency’s Johnson Space Center in Houston. Acaba had to balance flying a NASA crew member with previous spaceflight experience to command the flight, while ensuring NASA maintains an integrated crew with a Roscosmos cosmonaut who can operate their critical systems for continued, safe station operations.
“While we’ve changed crew before for a variety of reasons, downsizing crew for this flight was another tough decision to adjust to given that the crew has trained as a crew of four,” said Acaba. “I have the utmost confidence in all our crew, who have been excellent throughout training for the mission. Zena and Stephanie will continue to assist their crewmates ahead of launch, and they exemplify what it means to be a professional astronaut.”
The agency will share reassignment details for Cardman and Wilson when available.
“I am deeply proud of our entire crew,” said Cardman, “and I am confident Nick and Alex will step into their roles with excellence. All four of us remain dedicated to the success of this mission, and Stephanie and I look forward to flying when the time is right.”
Wilson added, “I know Nick and Alex will do a great job with their work aboard the International Space Station as part of Expedition 72.”
With 203 days logged in space, this will be Hague’s third launch and second mission to the orbiting laboratory. During his first launch in March 2018, Hague and his crewmate, Roscosmos’ Alexey Ovchinin, experienced a rocket booster failure, resulting in an in-flight, post-launch abort, ballistic re-entry, and safe landing in their Soyuz MS-10 spacecraft. Five months later, Hague launched aboard Soyuz MS-12 and served as a flight engineer aboard the space station during Expeditions 59 and 60. Hague conducted three spacewalks to upgrade space station power systems and install a docking adapter for commercial spacecraft. An active-duty colonel in the U.S. Space Force, Hague completed a developmental rotation at the Defense Department, and served as the Space Force’s director of test and evaluation from 2020 to 2022. In August 2022, Hague resumed duties at NASA, working on the Boeing Starliner Program until this flight assignment. Follow @astrohague on X and Instagram.
This will be Gorbunov’s first trip to space and the station. Born in Zheleznogorsk, Kursk region, Russia, he studied engineering with qualifications in spacecraft and upper stages from the Moscow Aviation Institute. Gorbunov graduated from the military department with a specialty in operating and repairing aircraft, helicopters, and aircraft engines. Before his selection as a cosmonaut in 2018, he worked as an engineer for Rocket Space Corp. Energia and supported cargo spacecraft launches from the Baikonur Cosmodrome.
Hague and Gorbonov will become members of the Expedition 72 crew aboard the station. They will join Wilmore, Williams, fellow NASA astronaut Don Pettit, and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner conducting scientific research and maintenance activities into the station’s 24th year of continuous human presence.

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 SpaceX officials announced during a news conference Friday their plan to launch the agency’s SpaceX Crew-9 mission to the International Space Station no earlier than Sunday, Aug. 18. Watch a full replay of the news conference.
Crew-9 is the ninth crew rotation mission with SpaceX to the space station under NASA’s Commercial Crew Program. The mission will carry NASA astronauts Zena Cardman, spacecraft commander; Nick Hague, pilot; and Stephanie Wilson, mission specialist; as well as Roscosmos cosmonaut Alexander Gorbunov to the orbiting laboratory for a six-month science mission. This will be the first spaceflight for Cardman and Gorbunov, the second mission to the space station for Hague, and the fourth spaceflight for Wilson, who has spent 42 days in space aboard three space shuttle Discovery missions – STS-120, STS-121, and STS-131.
During a separate crew news conference later on Friday, Cardman, Hague, Wilson, and Gorbunov answered reporters’ questions and discussed topics such as the inspiration behind the Crew-9 mission patch design, research they’ll complete in microgravity, and how they prepare for a long-duration flight. Watch a full replay of the crew news conference here.
“I am absolutely honored to be here with my crewmates, who have been an awesome team – Nick, Stephanie, and Alex. They have shown so much technical excellence. They are also deeply kind and incredible teammates who have been really fun to work with, which has just made this a dream assignment for me,” said Cardman.
The international crew will lift off from NASA Kennedy Space Center’s Launch Complex 39A in Florida aboard a SpaceX Falcon 9 rocket and Dragon spacecraft. The Dragon spacecraft supporting this flight, named Freedom, previously flew on SpaceX’s Crew-4 and Axiom Space’s Ax-2 and Ax-3 missions.

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.

NASA and Boeing engineers are evaluating results from last week’s engine tests at NASA’s White Sands Test Facility in New Mexico as the team works through plans to return the agency’s Boeing Crew Flight Test from the International Space Station in the coming weeks.
Teams completed ground hot fire testing at White Sands and are working to evaluate the test data and inspect the test engine. The ongoing ground analysis is expected to continue throughout the week. Working with a reaction control system thruster built for a future Starliner spacecraft, ground teams fired the engine through similar inflight conditions the spacecraft experienced on the way to the space station. The ground tests also included stress-case firings, and replicated conditions Starliner’s thrusters will experience from undocking to deorbit burn, where the thrusters will fire to slow Starliner’s speed to bring it out of orbit for landing in the southwestern United States. For a detailed overview of the test plans, listen to a replay of a recent media teleconference with NASA and Boeing leadership.
“I am extremely proud of the NASA, Boeing team for their hard work in executing a very complex test series,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We collected an incredible amount of data on the thruster that could help us better understand what is going on in flight. Next, our team has moved into engine tear downs and inspections which will provide additional insight as we analyze the results and evaluate next steps.”
Integrated ground teams also are preparing for an in-depth Agency Flight Test Readiness Review, which will evaluate data related to the spacecraft’s propulsion system performance before its return to Earth. The date of the agency review has not yet been solidified.
NASA and Boeing leadership plan to discuss the testing and analysis work in detail during a media briefing next week. More information on the briefing will be made available soon.
While testing and analysis are happening on Earth, NASA astronauts Butch Wilmore, Starliner mission commander, and Suni Williams, mission pilot, are working alongside the Expedition 71 crew. The two participated in vein scans using the Ultrasound 2 device on Monday. Doctors on the ground monitored in real-time as the pair took turns imaging each other’s neck, shoulder, and leg veins. Afterward, Wilmore scanned the veins of fellow NASA astronaut Matthew Dominick, helping researchers understand how microgravity affects the human body.
Wilmore and Dominick also spent a portion of the day taking inventory of the food stored aboard the space station. Williams worked on a pair of studies, first exploring the use of microgravity to manufacture higher-quality optical fibers than on Earth. Williams also investigated using fluid physics, such as surface tension, to overcome the lack of gravity when watering and nourishing plants grown in space.

NASA astronauts Butch Wilmore, commander, and Suni Williams, pilot, of NASA’s Boeing Crew Flight Test, continue contributing to International Space Station research and activities since their arrival on June 6 to the orbiting laboratory. Wilmore and Williams have completed half of all hands-on research time conducted aboard the station as the expedition crew prepares for the departure of Northrop Grumman’s Cygnus. As packing takes most of the crew’s time, the extra help from Wilmore and Williams allows packing and research to happen simultaneously. To learn more about what other crew members are doing aboard the International Space Station, visit: blogs.nasa.gov/spacestation.
Media are invited to hear Wilmore and Williams discuss their mission during an Earth-to-space call at 11 a.m. EDT Wednesday, July 10. Read the agency’s coverage advisory for more information.
On July 1, Wilmore and Williams spent the morning in the Permanent Multipurpose Module, organizing stowage and tidying up. Wilmore then moved into the Japanese Experiment Module to disassemble an empty NanoRacks CubeSat Deployer in preparation for upcoming NanoRacks missions.
Later, Wilmore prepped and viewed samples for the Moon Microscope, a demonstration that allows flight surgeons on Earth to diagnose illnesses and could provide diagnostic capabilities for crews on future missions to the Moon and Mars. Meanwhile, Williams conducted some routine orbital pluming, then audited U.S. stowage items housed inside the Zarya module.
On July 2, Wilmore joined NASA astronaut Tracy Dyson to load trash and discarded gear inside Northrop Grumman’s Cygnus spacecraft. Cygnus is scheduled to be released from the Unity module later this month for disposal over the South Pacific Ocean, ending its five-and-a-half-month stay at the orbiting lab.
Williams spent most of Tuesday on Starliner operations and then assessed the air flow of the pump filter attached to the Advanced Plant Habitat. At the end of the day, Williams and all eight of her crewmates held a conference with ground teams.
Also, on July 2, teams brought the Starliner spacecraft out of quiescent mode to conduct mission data loads, or MDLs. These are files for the spacecraft’s computer to understand current inertial and relative navigation states, Earth rotation, thermal conditioning, and more. The spacecraft was commanded back to a docked quiescent mode after MDL loading was complete.
