The astronauts who will soon fly to the International Space Station on NASA’s SpaceX Crew-3 mission just walked out of the double doors below the Neil A. Armstrong Building’s Astronaut Crew Quarters and made their way to the Tesla Model X cars that will take them to Launch Complex 39A.
Since the late 1960s, Pads A and B at Launch Complex 39 have supported America’s major space programs, with Pad A used most frequently for launches under the Space Shuttle Program. After the retirement of the shuttle program in 2011, Pad A helped usher in a new era of spaceflight with the historic Demo-1 launch for the agency’s Commercial Crew Program, which returned human spaceflight capability to the U.S.
Crew-3 astronauts Raja Chari, Tom Marshburn, Kayla Barron, and Matthias Maurer have finished putting on their SpaceX spacesuits and will soon depart the Neil A. Armstrong Operations and Checkout Building for the short journey to Launch Complex 39A. At the pad, a SpaceX Falcon 9 rocket and Crew Dragon spacecraft, named Endurance by the crew, stand ready for liftoff.

Tonight, Nov. 10, a SpaceX Falcon 9 rocket and Crew Dragon spacecraft are scheduled to lift off from Kennedy Space Center’s Launch Complex 39A, carrying NASA astronauts Raja Chari, Tom Marshburn, and Kayla Barron, as well as ESA (European Space Agency) astronaut Matthias Maurer to the International Space Station for the third crew rotation mission under the agency’s Commercial Crew Program.
Liftoff is targeted for 9:03 p.m. EST – an instantaneous launch window – and launch weather officers with the 45th Weather Squadron at Cape Canaveral Space Force Station are predicting a 70% chance of favorable weather conditions for launch. The primary weather concerns are cumulus clouds and flight through precipitation. Teams also continue to monitor the weather conditions along in Crew Dragon’s flight path, which is expected to be favorable for launch. Live countdown coverage will begin at 4:45 p.m. on NASA Television and the agency’s website, as well as right here on the blog.
Following liftoff, the Crew-3 astronauts will have a 22-hour journey to the space station, where they will be greeted by NASA astronaut Mark Vande Hei and cosmonauts Anton Shkaplerov and Pyotr Dubrov – the Expedition 66 crew already on board. Crew-3 astronauts will remain at the station for a six-month science mission, living and working as part of a seven-member crew.

The earliest possible opportunity for NASA’s SpaceX Crew-3 launch is 9:51 p.m. EST Monday, Nov. 8, if mission teams do not pursue Crew-2 return on Sunday, Nov. 7 or Monday. Nov. 8.
Mission teams will make a final decision on whether to prioritize Crew-3’s launch or Crew-2’s return in the coming daysbased on the likelihood of favorable conditions for a Crew Dragon splashdown or Crew Dragon launch. NASA and SpaceX also are reviewing the time needed between launch or return operations.
NASA and SpaceX are forgoing launch opportunities Saturday, Nov. 6 and Sunday, Nov. 7, due to unfavorable weather conditions. Weather officials with the 45th Weather Squadron forecast only a 40% chance of favorable launch weather on Saturday, Nov. 6, with the primary concerns revolving around liftoff winds, cumulus clouds, and surface electric field constraints. The down range weather also is not acceptable on Sunday, Nov. 7 due to risks associated with launch abort sites up the eastern seaboard.
Mission teams still are monitoring weather conditions for a launch attempt on Monday, Nov. 8. The primary operational concern is strong winds at the pad and unfavorable conditions down range.
“These are dynamic and complex decisions that change day by day,” said Steve Stich, NASA’s Commercial Crew Program manager. “The weather in November can be especially challenging, so our goal is to move forward on the plan with the highest probability of mission assurance and crew safety.”

The agency continues to monitor a minor medical issue involving one of the Crew-3 astronauts, which is expected to be clear prior to launch.
The Crew-3 flight will carry NASA astronauts Raja Chari, mission commander;Tom Marshburn, pilot; and Kayla Barron, mission specialist; as well as ESA (European Space Agency) astronaut Matthias Maurer, also a mission specialist, to the space station for a six-month science mission, staying aboard until about late April 2022.
The SpaceX Crew Dragon spacecraft and Falcon 9 rocket are in good shape and will remain at Launch Complex 39A at Kennedy Space Center.
The Crew-2 flight will return to Earth with NASA astronauts Shane Kimbrough and Megan McArthur, JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide, and ESA (European Space Agency) astronaut Thomas Pesquet.Crew 2’s Dragon undocking depends on a variety of factors, including vehicle readiness, recovery team readiness, weather, sea states, and other factors.
The Crew Dragon spacecraft is capable of staying in orbit for at least 210 days as a NASA requirement. Additional analysis could allow the spacecraft to remain in orbit for longer, if necessary. Crew Dragon Endeavour remains healthy while currently docked to the space station.
Teams are reviewing all options for safely launching and returning crew members to continue the agency’s important work on the International Space Station. Updated Crew-3 launch and Crew-2 return timelines will be provided in the coming days.
