SpaceX’s Falcon 9 lifted off from Launch Complex 39A at Florida’s Kennedy Space Center at 11:43 a.m. Eastern on Friday, sending NASA’s Crew-11 to the International Space Station after a one-day weather delay. The rocket’s first-stage booster, flying for the third time, returned to Landing Zone 1 minutes later, while the Crew Dragon capsule Endeavour—on its record-setting sixth mission—continued toward orbit. Commanded by NASA astronaut Zena Cardman, the multinational crew includes NASA pilot Mike Fincke, Japan’s Kimiya Yui and Russia’s Oleg Platonov. The four are due to dock autonomously with the station at about 3 a.m. Saturday following a roughly 15-hour chase, bringing the orbiting laboratory’s headcount to 11 for a short hand-over with Crew-10. Crew-11 is the 11th operational rotation flight arranged under NASA’s Commercial Crew Program and Dragon’s 19th human spaceflight overall. NASA says the astronauts are expected to spend roughly six months—potentially up to eight—conducting research ranging from stem-cell production and plant biology to experiments aimed at protecting eyesight and preparing for future lunar missions.
