The SpaceX Crew-9 mission, which will send two astronauts to the International Space Station (ISS) aboard a Crew Dragon spacecraft, has encountered another delay. This latest setback is just for one day, with the new launch date now scheduled for September 26.
The mission was initially planned for an August 18 launch with a crew of four, but was postponed to accommodate the return of the struggling Boeing Starliner capsule, which went back to the ISS uncrewed. Following this decision, NASA opted to keep astronauts Butch Wilmore and Suni Williams—who arrived at the ISS on the Starliner—stationed there as part of Crew-9. Consequently, the Crew Dragon will have two empty seats reserved for them to use for their return in February of the following year.
The Crew-9 launch was once again set for September 25, but teams requested an additional day to finalize prelaunch operations, including hardware processing at Space Launch Complex 40 in Cape Canaveral, Florida. NASA officials noted that this delay would also allows for ongoing weather monitoring prior to liftoff.
The revised launch time is set for 2:05 p.m. ET (11:05 a.m. PT) on Thursday, September 26. The mission will see NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov embarking on the journey. They will work alongside Wilmore and Williams, in addition to three Soyuz crew members, and current Crew-8 members who will depart for Earth after a brief handover.
This mission marks Hague’s second visit to the ISS, although it’s his third space launch, considering he also participated in another mission that was aborted shortly after takeoff. He previously made it to the station during Expeditions 59 and 60 in 2019 and has accumulated a total of 203 days in space to date.
Upon their arrival, the crew will engage in various scientific experiments, such as studying blood cell development in a microgravity environment and exploring the potential benefits of vitamin B supplements in mitigating vision issues associated with long-duration space missions. They will also attend to maintenance tasks on the station, including the installation of special patches on an X-ray telescope known as NICER, which is mounted on the ISS. These patches are designed to prevent light leaks and enhance the accuracy of the telescope’s readings.
