SpaceX's Crew Dragon Freedom spacecraft docked with the Harmony module of the International Space Station, completing the first part of its Crew-12 mission that began with its launch about 34 hours earlier. Andrey Fedyaev, Jack Hathaway, Jessica Meir, and Sophie Adenot join the Expedition 74 crew.

A little while ago, SpaceX's Crew Dragon Freedom spacecraft blasted off atop a Falcon 9 rocket from the Kennedy Space Center in its Crew-12 or SpaceX Crew-12 mission. After almost exactly ten minutes, it successfully separated from the rocket's last stage and went en route to carry out its mission.

A little while ago, SpaceX's Crew Dragon Endeavour spacecraft completed its Crew-11, or SpaceX Crew-11, mission for NASA with a successful splashdown. Aboard were astronauts Zena Cardman, Michael Fincke, and Kimiya Yui, and cosmonaut Oleg Platonov, who had arrived at the International Space Station on August 2, 2025, as part of Expedition 73/74.

"the three #cosmonauts would have had a good chance of returning in the broken #Soyuz. Like me, #ChrisHadfield expressed his basic confidence in the Soyuz.
Pretty much all important functions can be triggered by the crew. For all points in time, e.g. for igniting the jets, a table is sent up daily, which is printed out and kept in the Soyuz. I can't say in detail whether the cruise engine overheats in the absence of cooling, but in simulations pretty much everything was played in for us and we still got as far as the upper atmosphere. From there on, the leaky cooling doesn't matter anyway. If there's a moisture problem in the capsule before the braking shock (that's where the cooling acts as a condensation surface) or it gets too hot, thanks to the Sokol #spacesuits you can deflate the air in the return capsule and come back under pure oxygen pressure. Very uncomfortable, but #doable. Soyuz is a life saver, not a limb saver, we were always told."

#introduction 🖖

I’ve worked at #NASA since the beginning of the #internationalspacestation , training #astronauts , #cosmonauts , and #flightcontrollers on guidance, navigation, control, and propulsion. I was a flight controller for the visiting vehicles to ISS. I co-led NASA’s instructor training program. Today, I manage instructors, software developers, #InstructionalDesigners, and video producers.

I love teaching. I exercise those muscles as a #sciencecommunicator on #quora.
