The grand Delta finale is upon us, as United Launch Alliance (ULA) prepares to launch its last Delta IV rocket and bid farewell to an iconic rocket family that dates back to the Cold War.
Update: March 28, 4:18 p.m. ET: The launch of Delta IV Heavy rocket was scrubbed due to an “issue with the gaseous nitrogen pipeline which provides pneumatic pressure to the launch vehicle systems,” ULA wrote on X. Liftoff of the rocket is now scheduled for Friday at 1:37 p.m. ET.
Update: March 29: A new date for the launch of Delta IV Heavy rocket will be provided as the team continue to troubleshoot an issue that came up shortly before launch time on Thursday. “More time is needed to instill confidence in the system,” ULA wrote on X. “We will continue to work with our customer to confirm our next launch attempt.”
