One Last Hurrah: ULA’s Final Delta IV Heavy Launch Targets New Window on March 29th

The historic final launch of the United Launch Alliance’s (ULA) mighty Delta IV Heavy rocket has faced another delay, but a new launch window is on the horizon. Originally scheduled for Thursday, March 28th, the mission was scrubbed due to an issue with the rocket’s gaseous nitrogen pipeline, which provides pneumatic pressure to its systems.

In an official statement, ULA confirmed the scrub and announced a new target launch date: “The launch of a United Launch Alliance Delta IV Heavy carrying the NROL-70 mission for the National Reconnaissance Office was scrubbed due to an issue with the gaseous nitrogen pipeline which provides pneumatic pressure to the launch vehicle systems. The team initiated operations to secure the vehicle. The launch is now planned for Fri., March 29 at 1:37 p.m. EDT.”
