NASA's Crew-12 Mission Progresses Through Launch Milestones
NASA's SpaceX Crew-12 mission advanced through several key pre-launch milestones, including crew arrival at the launch pad and suit-up procedures. The mission received the "go" for fueling after the crew access arm retracted, with the spacecraft later achieving autonomous flight after a successful launch and first-stage return.
- The international crew consists of NASA astronauts Jessica Meir (commander) and Jack Hathaway (pilot), along with mission specialists Sophie Adenot from the European Space Agency and Andrey Fedyaev from Roscosmos. This is the first spaceflight for Hathaway and Adenot, and the second for both Meir and Fedyaev. - The mission is scheduled to last approximately eight months, an increase from the previous standard of six months for NASA crews, a change prompted by budget constraints. The crew will serve as part of ISS Expeditions 74 and 75. - The Crew Dragon spacecraft, named "Freedom," is a flight-proven vehicle, having previously flown four other missions, including both NASA and private astronaut flights. The Falcon 9 booster supporting the mission was on its second flight and completed the first-ever landing at the newly constructed Landing Zone 40 at Cape Canaveral. - Key research objectives include technology demonstrations for future deep space missions, such as a miniaturized system to generate intravenous saline solution from potable water and automated monitoring of plant health for in-space food production. - Human health studies are a primary focus, with experiments examining how microgravity affects blood flow and clotting risk, as well as piloting skills for simulated lunar landings to assess disorientation during gravitational transitions. - The mission will restore the International Space Station's crew to its full complement of seven astronauts, following the early return of the Crew-11 mission due to a medical issue. - The Dragon spacecraft is designed to dock autonomously with the ISS at the Harmony module's space-facing port, though the crew can take manual control if necessary. The journey to the station is expected to take approximately 34 hours. - While in orbit, the crew will test the European Enhanced Exploration Exercise Device (E4D), a compact piece of equipment combining a rowing machine, bicycle, and strength device, designed for smaller habitats like the lunar Gateway.
