ULA Delta IV Heavy launch now aimed for next week

United Launch Alliance (ULA) has announced a refreshed launch schedule for the Delta IV Heavy rocket by next week to complete its 16th and final endeavor.

ULA will now launch on April 9 at 12:53 p.m. EDT. The Delta IV Heavy rocket will carry the NROL-70 mission for the National Reconnaissance Office (NRO) from Launch Complex-37 at Cape Canaveral Space Force Station, Florida.

This launch was planned earlier on March 28 and scrubbed due to an issue with liquid pump failure on the gaseous nitrogen pipeline. This part of the vehicle provides pneumatic pressure to the launch vehicle systems.

The Delta Launch Control held the liftoff at T-Minus for 4 minutes with less than a minute remaining in this built-in hold. The launch pad swing arm lock pins have retracted before the terminal count.

The company last week confirmed that the problem is being resolved with a new solution. You can check the live stream webcast here.
