SpaceX has delivered a new crew to the International Space Station in just 15 hours. The team, consisting of astronauts from the U.S., Russia, and Japan, launched from NASA’s Kennedy Space Center and arrived on Saturday. They will spend at least six months aboard, replacing colleagues who have been there since March. SpaceX plans to bring the previous crew back as early as Wednesday. NASA’s Zena Cardman and Mike Fincke, Japan’s Kimiya Yui, and Russia’s Oleg Platonov are now on board. Their arrival temporarily increases the space station’s population to 11.
