A new launch date and time will be provided pending results, the company stated.
"We continue to remedy the technical issues that caused the last scrub of the Delta IV Heavy, and are working with our partners, the National Reconnaissance Office and the U.S. "Said Gary Wentz, Vice President of Government and Commercial Programs," We understand that this is a high-priority mission for the nation's warfighters and we take our commitment to safety and mission assurance seriously.
