The International Space Station is pictured from the SpaceX Crew Dragon Endeavour during a fly around.NASA NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are headed to the International Space Station for the agency’s SpaceX Crew-9 mission in September. Once on station, these crew members will support scientific investigations that include studies of blood clotting, effects of moisture on plants grown in space, and vision changes in astronauts.
Here are details on some of the work scheduled during the Crew-9 expedition:
Blood cell development in space
Megakaryocytes Orbiting in Outer Space and Near Earth (MeF1) investigates how environmental conditions affect the development and function of megakaryocytes and platelets. Megakaryocytes, large cells found in bone marrow, and platelets, pieces of these cells, play important roles in blood clotting and immune response.
“Understanding the development and function of megakaryocytes and platelets during long-duration spaceflight is crucial to safeguarding the health of astronauts,” said Hansjorg Schwertz, principal investigator, at the University of Utah. “Sending megakaryocyte cell cultures into space offers a unique opportunity to explore their intricate differentiation process. Microgravity also may impact other blood cells, so the insights we gain are likely to enhance our overall comprehension of how spaceflight influences blood cell production.”
Results could provide critical knowledge about the risks of changes in inflammation, immune responses, and clot formation in spaceflight and on the ground.

The Neutron Star Interior Composition Explorer (NICER) telescope on the exterior of the space station measures X-rays emitted by neutron stars and other cosmic objects to help answer questions about matter and gravity.
In May 2023, NICER developed a “light leak” that allows sunlight to interfere with daytime measurements. Special patches designed to cover some of the damage will be installed during a future spacewalk, returning the instrument to around-the-clock operation.
“This will be the fourth science observatory and first X-ray telescope in orbit to be repaired by astronauts,” said principal investigator Keith Gendreau at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “In just a year, we diagnosed the problem, designed and tested a solution, and delivered it for launch. The space station team — from managers and safety experts to engineers and astronauts — helped us make it happen. We’re looking forward to getting back to normal science operations.”

Some astronauts experience vision changes, a condition called Spaceflight-Associated Neuro-ocular Syndrome. The B Complex investigation tests whether a daily B vitamin supplement can prevent or mitigate this problem and assesses how genetics may influence individual response.
“We still do not know exactly what causes this syndrome, and not everyone gets it,” said Sara Zwart, principal investigator, at the University of Texas Medical Branch, Houston. “It is likely many factors, and biological variations that make some astronauts more susceptible than others.”
One such variation could be related to a metabolic pathway that requires B vitamins to function properly. Inefficiencies in this pathway can affect the inner lining of blood vessels, resulting in leaks that may contribute to vision changes. Providing B vitamins known to affect blood vessel function positively could minimize issues in genetically at-risk astronauts.
“The concept of this study is based on 13 years of flight and ground research,” Zwart said. “We are excited to finally flight test a low-risk countermeasure that could mitigate the risk on future missions, including those to Mars.”

As people travel farther from Earth for longer, growing food becomes increasingly important. Scientists conducted many plant growth experiments on the space station using its Veggie hardware, including Veg-01B, which demonstrated that ‘Outredgeous’ red romaine lettuce is suitable for crop production in space.
Plant Habitat-07 uses this lettuce to examine how moisture conditions affect the nutritional quality and microbial safety of plants. The Advanced Plant Habitat controls humidity, temperature, air, light, and soil moisture, creating the precise conditions needed for the experiment.
Using a plant known to grow well in space removes a challenging variable from the equation, explained Chad Vanden Bosch, principal investigator at Redwire, and this lettuce also has been proven to be safe to consume when grown in space.
“For crews building a base on the Moon or Mars, tending to plants may be low on their list of responsibilities, so plant growth systems need to be automated,” Bosch said. “Such systems may not always provide the perfect growing conditions, though, so we need to know if plants grown in suboptimal conditions are safe to consume.”

NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov (Credit: NASA) Editor’s note: This release was updated on Aug. 30, 2024, to correct Roscosmos cosmonaut Aleksandr Gorbunov’s role to mission specialist.
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.
