Boeing has reshuffled a sequence of test flights planned for the company’s CST-100 Starliner capsule after stuck valves inside a test version of the ship’s service module caused a fuel spill in June, delaying the commercial spacecraft’s first unpiloted orbital demo mission until late this year or early 2019, and moving back the first crew launch to mid-2019, a company official said Wednesday.

Up to 24 launches are planned from Cape Canaveral in 2015, thanks to jam-packed manifests for SpaceX and United Launch Alliance to send up satellites for the U.S. military, NASA and commercial telecom operators.

The United Launch Alliance Atlas 5 rocket, standing 194 feet tall and and weighing a million pounds, unleashes two million pounds of thrust from its main engine and three solid-fuel boosters today to launch the EchoStar 19 commercial Internet broadcast satellite from Cape Canaveral, Florida.
