A SpaceX Falcon 9 rocket launched four astronauts on the Axiom Space Ax-4 mission to the International Space Station (ISS). The crew, including retired NASA astronaut Peggy Whitson as commander, will conduct nearly 60 experiments during their 14-day stay. The mission, involving astronauts from India, Poland, and Hungary, follows delays due to weather and a rocket leak. The Dragon capsule will dock with the ISS Thursday morning, and the crew will splash down off southern California after their mission. This is SpaceX's 18th human spaceflight.
