United Launch Alliance called off the planned liftoff of a Delta 4-Heavy rocket and a classified National Reconnaissance Office spy satellite from Vandenberg Air Force Base in California on Wednesday after indications of elevated hydrogen concentrations around one of the launcher’s main engines. Three previous launch attempts were scrubbed by technical concerns and bad weather.

SpaceX’s first launch since August took off Saturday from Vandenberg Air Force Base in California.

Liftoff occurred at 9:54 a.m. PST (12:54 p.m. EST; 1754 GMT), and the Falcon 9’s first stage landed on a barge in the Pacific a few minutes later.
