An upcoming launch from the Florida coast is delayed a day by weather. Three NASA astronauts and a Russian cosmonaut are due to blast off in a Crew Dragon spacecraft called Endeavour. The capsule will be on a SpaceX Falcon 9 rocket that's now expected to launch Saturday night from Kennedy Space Center. A NASA official said developing weather patterns were a concern. The Crew-8 mission calls for them to spend almost six months at the International Space Station conducting experiments.
