"Final Delta IV Heavy Rocket Launch Scrubbed Moments Before Liftoff"
The final launch of the United Launch Alliance's Delta IV Heavy rocket carrying the NROL-70 mission for the National Reconnaissance Office has been postponed to Friday due to an issue with the gaseous nitrogen pipeline. The launch will mark the end of a 64-year run for the Delta rocket fleet and is set to carry a classified payload into space. The ULA has not disclosed the nature of the payload, but it is likely a sophisticated satellite. The launch has faced delays due to unfavorable weather conditions, and the ULA is making way for its new Vulcan Centaur rocket as the Delta IV Heavy and Atlas V are reaching the end of their careers.
