United Launch Alliance engineers have resolved the problem that triggered an abort of a planned Delta 4-Heavy rocket launch Sept. 30, but the company said Friday it is continuing to evaluate a concern with the launch pad swing arm retraction system at Cape Canaveral. ULA said the Delta 4-Heavy’s mission to launch a classified National Reconnaissance Office spy satellite will be postponed beyond next week.

United Launch Alliance scrubbed the launch of a Delta 4-Heavy rocket Wednesday night less than 10 seconds before liftoff from Cape Canaveral, the second such abort suffered by this mission.. The launch of a classified National Reconnaissance Office spy satellite is expected to be delayed at least several more days as engineers assess the cause of Wednesday’s last-minute abort.
