The four crew members of NASA’s SpaceX Crew-9 mission, including NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov, pose for a photo aboard the International Space StationNASA Media are invited to hear from NASA’s SpaceX Crew-9 astronauts during a news conference beginning at 11:55 a.m. EST, Tuesday, March 4, from the International Space Station.
NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore will discuss their return to Earth on NASA+. Learn how to watch NASA content through a variety of platforms, including social media.
Media interested in participating must contact the newsroom at NASA’s Johnson Space Center in Houston no later than 5 p.m. Monday, March 3, at 281-483-5111 or jsccommu@mail.nasa.gov. To ask questions, media must dial into the news conference no later than 15 minutes prior to the start of the call. A copy of NASA’s media accreditation policy is online. Questions also may be submitted on social media using #AskNASA.
Crew-9 contributed to hundreds of scientific experiments, including swabbing the station’s exterior for microbes, printing 3D medical devices, and studying how moisture, orbital altitude, and ultraviolet light affect plant growth.
The crew will depart the space station after the arrival of Crew-10 and a short handover period. Ahead of Crew-9’s return, mission teams will review weather conditions at the splashdown sites off the coast of Florida prior to departure from station.
The mission is part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.

Improving space-based pharmaceutical research
View of the Ice Cubes experiment #6 (Kirara) floating in the Columbus European Laboratory module aboard the International Space Station.UAE (United Arab Emirates)/Sultan Alneyadi Researchers found differences in the stability and degradation of the anti-Covid drug Remdesivir in space and on Earth on its first research flight, but not on a second. This highlights the need for more standardized procedures for pharmaceutical research in space.
Long-term stability of drugs is critical for future space missions. Because multiple characteristics of spaceflight could influence chemical stability, the scientists repeated their experiment under circumstances as nearly identical as possible. This research used Kirara, a temperature-controlled incubator developed by JAXA (Japan Aerospace Exploration Agency) for crystallizing proteins in microgravity. Results also confirmed that a solubility enhancer used in the drug is radiation resistant and its quality was not affected by microgravity and launch conditions.
Evaluating postflight task performance
A test subject performing a sensorimotor field test on the ground.NASA/Lauren Harnett Immediately after returning from the International Space Station and for up to one week, astronauts perform functional tasks in ways similar to patients on Earth who have a loss of inner ear function. This finding suggests that comparing data from these patients and astronauts could provide insight into the role of the balance and sensory systems in task performance during critical parts of a mission such as landing on the Moon or Mars.
Spaceflight causes changes to the balance (vestibular) and sensory systems that can lead to symptoms such as disorientation and impaired locomotion. Standard Measures collects a set of data, including tests of sensorimotor function, related to human spaceflight risks from astronauts before, during, and after missions to help characterize how people adapt to living and working in space.
