What a long, strange trip it’s been: Butch Wilmore and Suni Williams finally concluded their never-ending story of Boeing’s Crewed Flight Test of Starliner yesterday when they landed in a SpaceX Crew Dragon in the Gulf of America near Tallahassee, Florida. Also aboard were NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov, with the four of them designated as Crew 9 on ISS Expedition 71/72.

After a nominal re-entry, the four landed at 5:57 p.m. EDT. Recovery teams on SpaceX vessels secured the spacecraft and assisted the crew while being circled by curious dolphins. Following their arrival on shore, the astronauts began the return procedures: extensive medical checks followed by travel to NASA’s Johnson Space Center in Houston for debriefings and reunions with their families.

Boeing’s Crew Flight Test (CFT) mission was as an 8-10 day demonstration flight for Starliner to validate its capabilities in transporting astronauts to and from the International Space Station. However, technical concerns, including issues with the spacecraft’s propulsion system, led NASA to opt for an uncrewed return of Starliner to conduct further testing and modifications before operational flights could commence.

For their part, Boeing disagreed with the decision, with the company arguing internally with NASA that Starliner was safe to ferry Williams and Williams back to Earth as planned. That was not to be, as NASA decided to fold the pair into Expedition 71/72 on ISS, and to bump two of the astronauts designated for Crew 9 — NASA astronauts Zena Cardman and Stephanie Wilson — from the mission.

Starliner would eventually return to Earth uncrewed in September, 2024, safely completing its mission via remote control and on-board programming.

Crew 9 Stats

During their missions, Williams and Wilmore traveled 121,347,491 miles, spent 286 days in space, and completed 4,576 Earth orbits. Hague and Gorbunov covered 72,553,920 miles, remained in orbit for 171 days, and completed 2,736 orbits. This mission marked Gorbunov’s first spaceflight. Hague has accumulated 374 days in space across two missions, Williams 608 days over three missions, and Wilmore 464 days across three flights.

Due to the unexpected long-term mission, Williams is now in second place for time spent in space by a female astronaut. Former NASA astronaut Peggy Whitson has accumulated a total of 675 days in space across multiple missions, making her the most experienced astronaut in terms of cumulative days, a record that Whitson will add to she commands the private Axiom Ax-4 mission to ISS later this year.

Crew-9’s mission included scientific research, maintenance operations, and technology demonstrations. Williams performed two spacewalks, partnering with Wilmore and Hague to remove a radio frequency antenna, collect external surface samples, and install protective patches on an X-ray telescope’s light filters. Williams set a new record for cumulative spacewalking time by a female astronaut, logging 62 hours and 6 minutes outside the station.

The crew conducted over 150 scientific studies and technology tests, dedicating more than 900 hours to research. Their work included plant growth experiments, stem cell technology investigations for treating blood disorders and cancer, and evaluations of circadian rhythm-supporting lighting systems. They also launched the first wooden satellite and studied microorganism survival in space by analyzing external samples from the station.

The mission marked the fourth flight of the Dragon spacecraft named Freedom, previously used for NASA’s SpaceX Crew-4 and Axiom Missions 2 and 3. Following retrieval, the spacecraft will undergo inspections and refurbishments at Cape Canaveral Space Force Station in preparation for future missions.

Shift Change

Crew-9’s comes shortly after the launch and docking at ISS of NASA’s SpaceX Crew-10, which completed the Crew 9 rotation. NASA astronauts Anne McClain and Nichole Ayers;  JAXA astronaut Takuya Onishi and Russian cosmonaut Kirill Peskov will now spend several months aboard Station, and will advance the scientific and engineering work planned for their stay.
