NASA announced a news briefing with SpaceX Crew-12 members and of NASA, Sophie Adenot of ESA, and Andrey Fedyaev of Roscosmos. The call is scheduled to begin at 2:45 p.m. EDT on Wednesday, Sept. 16, 2026, and will originate from the International Space Station.
The briefing will cover the crew’s mission aboard the station and their upcoming return to Earth. NASA provided an online viewing option at https://www.nasa.gov/live. Media wishing to participate were instructed to contact the Johnson Space Center newsroom in Houston no later than 5 p.m. CDT on Tuesday, Sept. 15, 2026, by calling 281-483-5111 or emailing jsccommu@mail.nasa.gov. Reporters must dial in at least 10 minutes before the start of the call. NASA’s media accreditation policy is available online.
Crew-12 joined Expedition 74/75 on the station and took part in hundreds of experiments. NASA identified several research efforts the crew supported, including studies of bacteria that cause pneumonia with implications for cardiovascular care, on-demand generation of intravenous fluids for future missions, and investigations into how individual physical characteristics may influence blood flow during spaceflight.
NASA said the Crew-12 team will leave the station after Crew-13 arrives and a short handover period. Ahead of departure, mission teams will assess weather at planned splashdown sites off the coast of California.
NASA emphasized the station’s role in advancing human spaceflight, expanding commercial activity in low Earth orbit, and preparing for long-duration missions to the Moon under the Artemis program and to Mars. The agency noted that humans have lived and worked continuously aboard the International Space Station for more than 25 years.
