SpaceX Crew-9 is the ninth operational NASA Commercial Crew Program flight and the 15th crewed orbital flight of a Crew Dragon spacecraft. Originally scheduled to launch a crew of four to the International Space Station (ISS) in mid-August 2024,the mission was delayed by more than a month due to technical issues with the Boeing Starliner Calypso spacecraft that was docked at the ISS for the Boeing Crew Flight Test. NASA ultimately decided to send the Starliner back to Earth uncrewed,launch Crew-9 with two crew members,and return with four crew members,including the two crew members of the Boeing Crew Flight Test. After that delay and other delays largely due to weather,Crew-9 launched on 28 September at 17:17:21 UTC (1:17:21 pm EDT,local time at the launch site).
The Crew-9 mission marked several milestones. It was the first crewed mission to launch from Cape Canaveral Space Launch Complex 40;astronaut Nick Hague was the first active U.S. Space Force Guardian to launch to space since the branch was established in 2019;and the mission is expected to be the first Crew Dragon to splashdown in the Pacific Ocean.
The mission was initially planned to transport four crew members—NASA astronauts Zena Cardman,Nick Hague,and Stephanie Wilson,along with Roscosmos cosmonaut Aleksandr Gorbunov—to the International Space Station (ISS). Cardman was assigned to be the commander and Hague the pilot,while Wilson and Gorbunov would serve as mission specialists. [2] However,due to technical issues with the Boeing Starliner,NASA decided to return the Starliner uncrewed and launch Crew-9 with two open seats to return the Boeing Crew Flight Test astronauts to Earth. [3]
On 24 August,NASA Administrator Bill Nelson,along with a panel of agency officials,announced that the Boeing Starliner would return uncrewed,with its astronauts returning on Crew-9. Later,on 30 August,NASA announced that Hague and Gorbunov will fly on Crew-9 with Hague serving as commander. Gorbunov was required to fly as part of a NASA-Roscosmos crew interchange agreement. [4] Prior to the official announcement,Ars Technica reported that there was disagreement within NASA over who should fill the commander's seat in those six days. According to the reporting,NASA Chief Astronaut,Joe Acaba had initially selected Cardman to continue as commander,which had been met with some concerns in the astronaut office,stemming from NASA's history of never launching a mission without a test pilot or experienced astronaut in command. Both Cardman and Gorbunov are rookie astronauts who have never served as a test pilot. Hague,on the other hand,has prior spaceflight experience and is one of the few individuals who have survived a launch abort with Soyuz MS-10. [5]
Following the crew changes,SpaceX,NASA,Cardman,Hague,Wilson,and Gorbunov collaborated for three weeks to identify how Hague could assume many of the tasks typically divided between the commander and pilot,and determine which tasks could be assigned to Gorbunov,who would sit in the pilot's seat during launch. While Gorbunov is a qualified engineer and holds the rank of test cosmonaut (making him eligible to be a Soyuz commander),he had only previously received basic training on the Dragon in his role as a mission specialist. [6] Although only serving in a limited capacity,Gorbunov will be the first Russian cosmonaut to be at the controls of an American spacecraft.

SpaceX Crew-9 is the ninth operational NASA Commercial Crew Program flight to the International Space Station (ISS) and the 15th crewed orbital mission for a SpaceX Dragon spacecraft. The flight was originally planned to deliver four crew members to the ISS for Expedition 72,a six-month science mission:NASA astronauts Zena Cardman (commander),Nick Hague (pilot),and Stephanie Wilson (mission specialist),along with Roscosmos cosmonaut Aleksandr Gorbunov (mission specialist). [2] However,NASA decided to return the two astronauts of the Starliner crewed flight test,using Crew-9. Therefore,Crew-9 launched with a crew of two instead. [7] Hague will serve as commander,flying alongside Gorbunov.
The Dragon spacecraft,named Freedom ,is a veteran of the SpaceX Crew-4 and Axiom Space's Ax-2 and Ax-3 missions. [8] The Falcon 9 first-stage booster,designated B1085,will be making its second flight.
Originally scheduled for 18 August 2024,the launch was rescheduled to 24 September after NASA decided to return the Boeing Starliner Calypso spacecraft of the Boeing Crew Flight Test without its crew. This delay provided NASA additional time to assess the Starliner's condition,develop a safe return plan for its crew,and reconfigure the Starliner's software for an uncrewed return. [9] [10] ISS has only two IDSS ports,and one was occupied by Crew-8 while the other was occupied by Starliner. Therefore,Crew-9 did not launch until after Starliner undocked. Until Crew-9 arrived,they arranged to use SpaceX Crew-8 as their temporary emergency evacuation spacecraft,after which they transferred to Crew-9. [11]
Crew-9 was slated to use Launch Complex 39A (LC-39A) at Kennedy Space Center,which had supported all previous SpaceX's crewed missions and is also the only pad that can support Falcon Heavy launches. When Crew-9's launch was rescheduled to 24 September,it was brought close to the launch NASA's Europa Clipper mission,which needed to launch from LC-39A on a Falcon Heavy during a 21-day window in early October. To avoid scheduling conflicts and ensure ample preparation time for both missions,SpaceX shifted the Crew-9 launch to Space Launch Complex 40 at Cape Canaveral Space Force Station. [12] This was the first crewed mission to lift off from SLC-40. SpaceX had been constructing a crew access tower at this location since 2023 to facilitate such operations. [13]
Hague,a U.S. Space Force colonel,is the first active member of the Space Force to launch into space since the branch was established in 2019. Because the launch moved to SLC-40,the mission also marks the first time a Space Force servicemember launched from a Space Force launch complex. [14]
Crew-9 relocated from Harmony forward to Harmony zenith on 3 November 2024,with all four of its crew aboard. This allowed CRS-31 to dock later dock to Harmony forward,from which it will be able to perform a test to reboost ISS. Relocations carry the full crew because the spacecraft is also the crew's "lifeboat".
The mission is scheduled to end with a splashdown in the Pacific Ocean in March 2025,a first for a Crew Dragon mission. While SpaceX Dragon 1 missions had previously landed in the Pacific,SpaceX and NASA had shifted recovery operations to the East Coast in 2019. The move allowed astronauts and critical cargo to return to Kennedy Space Center more quickly after splashdown,and SpaceX opened a facility in Florida to take in capsules after flight and prepare them for the next mission. However,the move had an unforeseen consequence:the trunk module had to be jettisoned before reentry,and while the team expected it would burn up,SpaceX became aware of at least four cases of trunk debris being found on land. The shift back to Pacific Ocean splashdowns means that the trunk can stay attached longer and be directed towards a remote area of the ocean called Point Nemo (nicknamed the spacecraft cemetery),where any debris that survives reentry will be unlikely to cause damage. [15] [16]
Hague and Gorbunov arrived at Kennedy Space Center on Saturday,21 September,to prepare for their mission. The crew was scheduled to quarantine at the Operations and Checkout Building,where they conducted a dry dress rehearsal,adjusted their sleep schedules,and rehearsed flight procedures. At the time,the launch date was set for Thursday,26 September. [17]
On Tuesday,24 September,the SpaceX Falcon 9 rocket and Crew Dragon Freedom capsule were rolled out to SLC-40. [18] However,due to the approaching Hurricane Helene,NASA announced that the Crew-9 launch was delayed until Saturday,28 September.
Following a successful static fire and final dress rehearsal on Tuesday,the SpaceX Dragon and Falcon 9 rocket were rolled back to the hangar on Wednesday,25 September,as a precaution against potential weather impacts from Hurricane Helene,which was forecast to make landfall near the Florida panhandle on Thursday,26 September. [19]
Crew-9 was able to lift off on the first attempt on 28 September at 17:17:21 UTC (1:17:21 pm EDT,local time at the launch site). [20] With a launch weather forecast that predicted a 45% chance of violating weather constraints and rain clouds that passed by as the crew boarded the rocket,NASA leaders later remarked that they had "threaded a needle" regarding the weather. [21] After lifting the Dragon and second-stage to an altitude of 70 kilometers (43 mi;38 nmi) the rocket's first stage,Booster 1085 returned to the Cape Canaveral Space Force Station and touched down at Landing Zone 1,seven minutes and 36 seconds after launch,completing its second flight. [22] The second stage continued to lift the Dragon to an altitude of 200 kilometers (120 mi;110 nmi) before separation. [23]
A few hours later,when the second stage was commanded to make a destructive reentry,it experienced an off-nominal deorbit burn,deviating from its planned trajectory. Although it landed safely in the ocean,the impact point was outside the designated target area. SpaceX typically commands its second stages to re-enter the atmosphere and land in the ocean to minimize orbital debris. The off-target landing increased the potential risk of harm,as aircraft and mariners were not instructed to avoid the area. In response,SpaceX announced a temporary grounding of the Falcon 9 rocket while investigating the root cause of the mishap. [24] On 30 September the Federal Aviation Administration grounded the Falcon 9. [25] An exception was made for the launch of ESA's Hera. The FAA cleared the Falcon 9 to resume flights on 11 October. [26]

Barry Eugene "Butch" Wilmore is an American NASA astronaut and United States Navy test pilot. He has had three spaceflights, the first of which was an 11-day Space Shuttle mission in November 2009, to the International Space Station. Wilmore was designated as pilot with five other crew members on Space Shuttle Atlantis for the mission STS-129. He served as part of Expedition 41 to the International Space Station, and in 2024 returned to the ISS on the Boeing Crew Flight Test, the first crewed mission of the Boeing Starliner. As of October 2024, he is in space and is set to return to Earth in 2025.
Space Launch Complex 40 (SLC-40), sometimes referred to as "Slick Forty," is a launch pad located at Cape Canaveral Space Force Station in Florida. Initially opened as Launch Complex 40 (LC-40) and used by the United States Air Force for 55 launches of rockets from the Titan family between 1965 and 2005. In 2007, SpaceX acquired a lease for SLC-40 and has since transformed the complex into a high-volume launch site for the Falcon 9 rocket. As of November 2024, the pad has hosted over 220 Falcon 9 launches.
The Boeing Starliner is a spacecraft designed to transport crew to and from the International Space Station (ISS) and other low-Earth-orbit destinations. Developed by Boeing under NASA's Commercial Crew Program (CCP), it consists of a reusable crew capsule and an expendable service module.
Development of the Commercial Crew Program (CCDev) began in the second round of the program, which was rescoped from a smaller technology development program for human spaceflight to a competitive development program that would produce the spacecraft to be used to provide crew transportation services to and from the International Space Station (ISS). To implement the program, NASA awarded a series of competitive fixed-price contracts to private vendors starting in 2011. Operational contracts to fly astronauts were awarded in September 2014 to SpaceX and Boeing, and NASA expected each company to complete development and achieve crew rating in 2017. Each company performed an uncrewed orbital test flight in 2019.
Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of a reusable space capsule and an expendable trunk module, has two variants: the 4-person Crew Dragon and Cargo Dragon, a replacement for the Dragon 1 cargo capsule. The spacecraft launches atop a Falcon 9 Block 5 rocket, and the capsule returns to Earth through splashdown.
Crew Dragon Demo-1 was the first orbital test of the Dragon 2 spacecraft. The mission launched on 2 March 2019 at 07:49:03 UTC, and arrived at the International Space Station on 3 March 2019, a little over 24 hours after the launch. The mission ended with a splashdown on 8 March 2019 at 13:45:08 UTC.
The Boeing Starliner Orbital Flight Test was the first orbital mission of the CST-100 Starliner spacecraft, conducted by Boeing as part of NASA's Commercial Crew Program. The mission was planned to be an eight-day test flight of the spacecraft, involving a rendezvous and docking with the International Space Station (ISS), and a landing in the western United States. The mission was launched on December 20, 2019 at 11:36:43 UTC or 06:36:43 AM EST; however an issue with the spacecraft's Mission Elapsed Time (MET) clock occurred 31 minutes into flight. This anomaly caused the spacecraft to burn into an incorrect orbit, preventing a rendezvous with the International Space Station (ISS). The mission was reduced to just two days, with the spacecraft successfully landing at White Sands Space Harbor on December 22, 2019.
Boeing Crew Flight Test (Boe-CFT) was the first crewed mission of the Boeing Starliner capsule. Launched on 5 June 2024, the mission flew a crew of two NASA astronauts, Barry E. Wilmore and Sunita Williams, from Cape Canaveral Space Force Station to the International Space Station. The mission was meant to last eight days, ending on 14 June with a landing in the American Southwest. However, Starliner's thrusters malfunctioned as it approached the ISS. After more than two months of investigation, NASA decided it was too risky to return Wilmore and Williams to Earth aboard Starliner. Instead, the Boeing spacecraft returned uncrewed on 7 September 2024, and the astronauts will ride down on the SpaceX Crew-9 spacecraft in March 2025.
Zena Maria Cardman is an American geobiologist and NASA astronaut.
Boeing Starliner-1, also called Post Certification Mission-1 (PCM-1), is the name of the first operational crewed mission of the Boeing Starliner to the International Space Station (ISS) as part of the Commercial Crew Program. It was originally planned as the first Starliner mission following the Starliner Crewed flight test (CFT). The CFT was not a complete success, and as of November 2024, the launch date and name for the next Starliner mission is not known.
SpaceX Crew-1 was the first operational crewed flight of a Crew Dragon spacecraft, and the maiden flight of the Crew Dragon Resilience spacecraft. It was also the second crewed orbital flight launch by the United States since that of STS-135 in July 2011. Resilience launched on 16 November 2020 at 00:27:17 UTC on a Falcon 9 from Kennedy Space Center Launch Complex 39A (LC-39A), carrying NASA astronauts Michael Hopkins, Victor Glover and Shannon Walker, along with JAXA astronaut Soichi Noguchi, all members of the Expedition 64 crew. The mission was the second overall crewed orbital flight of the Crew Dragon.
The Boeing Orbital Flight Test-2 was a repeat of Boeing's unsuccessful first Orbital Flight Test (Boe-OFT) of its Starliner spacecraft. The uncrewed mission was part of NASA's Commercial Crew Program. OFT-2, using Starliner Spacecraft 2, launched 19 May 2022 and lasted 6 days. Starliner successfully docked with the International Space Station (ISS) on 21 May 2022. It stayed at the ISS for 4 days before undocking and landing in the White Sands Missile Range on 25 May 2022.
Boeing Starliner Calypso is a space capsule manufactured by Boeing and used in NASA's Commercial Crew Program. On 20 December 2019, Calypso launched on the Boeing Orbital Flight Test mission, an uncrewed test flight of Starliner to the International Space Station. The spacecraft was scheduled to dock to the ISS and then return to Earth following a week in space, although due to several software issues the spacecraft was unable to rendezvous with the station and landed after two days in space, resulting in Boeing needing to schedule a second Orbital Flight Test. It flew with two astronauts for Starliner Crewed Flight Test on its second mission in June 2024.
The Commercial Crew Program (CCP) provides commercially operated crew transportation service to and from the International Space Station (ISS) under contract to NASA, conducting crew rotations between the expeditions of the International Space Station program. American space manufacturer SpaceX began providing service in 2020, using the Crew Dragon spacecraft, and NASA plans to add Boeing when its Boeing Starliner spacecraft becomes operational no earlier than 2025. NASA has contracted for six operational missions from Boeing and fourteen from SpaceX, ensuring sufficient support for ISS through 2030.
Crew Dragon Endeavour is the first operational Crew Dragon reusable spacecraft manufactured and operated by SpaceX. The spacecraft is named after Space ShuttleEndeavour. It first launched on 30 May 2020 to the International Space Station (ISS) on the Crew Dragon Demo-2 mission. It has subsequently been used for the SpaceX Crew-2 mission that launched in April 2021, the private Axiom Mission 1 that launched in April 2022, the SpaceX Crew-6 mission that launched in March 2023, and the SpaceX Crew-8 mission from early March 2024 to late October 2024. As of November 2024, Endeavour holds the single-mission record for the most time in orbit by an American crewed spacecraft at 235 days.
SpaceX Crew-2 was the second operational flight of a Crew Dragon spacecraft, and the third overall crewed orbital flight of the Commercial Crew Program. The mission was launched on 23 April 2021 at 09:49:02 UTC, and docked to the International Space Station on 24 April at 09:08 UTC.
SpaceX Crew-8 was the eighth crewed operational NASA Commercial Crew flight and the 13th overall crewed orbital flight of a Crew Dragon spacecraft. The mission launched on 4 March 2024.
Expedition 72 is the 72nd long-duration expedition to the International Space Station (ISS). The expedition began with the departure of Soyuz MS-25 on 23 September 2024 and is led by Sunita Williams, her second time serving as commander of the ISS. It will continue the extensive scientific research conducted aboard the ISS, focusing on various fields, including biology, human physiology, physics, and materials science. The crew members will also maintain and upgrade the space station systems.
Aleksandr Vladimirovich Gorbunov is a Russian cosmonaut and aerospace engineer. A native of Zheleznogorsk, he graduated with a degree in engineering from the Moscow Aviation Institute.
So now we have to do the pilot and the commander role as a single person, you know, so there's not going to be a pilot there. Now we have had three weeks of training and it's been awesome to watch the full team come together, to watch the SpaceX team, to watch the NASA team surge and just roll your sleeves up and figure out, okay, how do we need to change things? And it's, you know, we've had previously flown Dragon crew members in the astronaut office that have helped support us. Zena and Stephanie have been integral to this effort and have pointed out and helped us come up with some great ways to understand what we can and can't do given the training that Alex has cause he's there, he's been through this training for two years. And so, there are things that he is extremely capable of doing that I would do as a pilot. And so we want to leverage those. But there's also a lot of things that he hasn't been trained on. And so we identify where those limitations are and then, and then I figure out what I need to do in order to cover down on all of that.
The Crew-9 mission is now expected to launch from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. This will be the first crewed launch from this complex, which SpaceX has built up in addition to its crew tower at Launch Complex 39A at nearby Kennedy Space Center.
