Max Q, or the moment of peak mechanical stress on the rocket, has been reached.
The Falcon 9 rocket and Crew Dragon spacecraft Resilience lit up the Florida early evening sky, lifting off from Kennedy Space Center’s Launch Complex 39A at 7:27 p.m. EST! Mike Hopkins, Victor Glover, Shannon Walker and Soichi Noguchi have started their 27.5-hour journey to the International Space Station on NASA’s SpaceX Crew-1 mission.
Max Q (the moment of peak mechanical stress on the rocket) will happen during the next minute.
Crew-1 mission Commander Mike Hopkins just uttered the following words: “To all the people at NASA and SpaceX, by working together through these difficult times, you’ve inspired the nation, the world — and in no small part — the name of this incredible vehicle, Resilience. And now it’s time for us to do our part. Crew-1 for all.”
Fuel loading is complete on the second stage, and liquid oxygen loading has begun. Everything remains on target for the 7:27 p.m. EST launch of NASA’s SpaceX Crew-1 mission from Kennedy Space Center in Florida.
Weather conditions remain 80% favorable.
Right on schedule — at T-minus 35 minutes — RP-1 (rocket grade kerosene) loading and first stage liquid oxygen loading has begun.
Liftoff is scheduled for 7:27 p.m. EST.
The launch escape system for the Crew Dragon spacecraft, Resilience, is now armed. From liftoff until they reach orbit, roughly 12 minutes, the crew would be able to escape safely in the unlikely event of an anomaly.
Up next is propellant loading.
The crew access arm has retracted. Coming up next, the Dragon launch escape system will be armed.
Weather has been upgraded from 50% to 80% chance of favorable conditions for liftoff of NASA’s SpaceX Crew-1 mission. Launch is slated for 7:27 p.m. EST.
Confirmation was received from Commander Mike Hopkins that Crew Dragon, named Resilience by the crew, is “go” for launch! The next call will come at T-mins 45 minutes from the launch director. Weather looks good and we remain on target for a 7:27 p.m. EST launch.
In about 50 minutes, Resilience, with Hopkins, Pilot Victor Glover and Mission Specialists Shannon Walker and Soichi Noguchi aboard, will lift off from Kennedy Space Center’s Launch Complex 39A.
The SpaceX closeout team has left the crew access arm. Launch, set for 7:27 p.m. EST, is now just over an hour away.
Stay with us as the countdown continues. We’ll keep you updated on the key milestones throughout this historic mission. On NASA Television and the agency’s website, there is continuous live coverage of important Crew-1 activities.
