SPACE: SpaceX rocket issue delays astronaut launch. “SpaceX and NASA have delayed the launch of the company’s upcoming astronaut mission to the first half of November to investigate a problem with gas generators in a Falcon 9 rocket’s engine. A NASA statement said only that SpaceX data from a recent launch attempt of another Falcon 9 rocket showed “off-nominal behavior” in the generators, and the delay would allow the company to complete tests and review more data.”
