In a 1 October 2026 NASA blog post, the agency reported that NASA astronauts Jessica Watkins and Luke Delaney, CSA (Canadian Space Agency) astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov were in the suit-up room of the Astronaut Crew Quarters in Kennedy Space Center's Neil A. Armstrong Operations and Checkout Building in Florida. SpaceX suit technicians assisted as the crew put on custom-fitted spacesuits and checked for leaks.

The suits supply pressurization to protect the crew from potential cabin depressurization, and a port on the thigh connects to life support systems, including air and power. They also feature touchscreen-compatible gloves and a flame-resistant outer layer.

For Watkins, the flight is her second on a SpaceX Dragon spacecraft but her first wearing the company's updated inflight spacesuit. The design, first used by a NASA astronaut on the Crew-11 mission, removes the inseam zipper and adds a spiral zipper on the torso, allowing the suit to split into upper and lower halves. The suits are adjustable in height and can expand by more than 14 inches.

According to the post, U.S. Space Force 45th Weather Squadron officials predicted a 40% chance of favorable conditions at the launch pad for liftoff.
