Of the
10 launches,
four are national security satellites,
three are NASA missions, and other
three are commercial —
one is Astrobotic’s lunar lander and the other
two are Boeing Starliner commercial crew capsule launches to the International Space Station.
One of the four national security launches will be a National Reconnaissance Office mission on a Delta 4 Heavy rocket, an aging vehicle that has to fly four more times before it’s retired. ULA last week launched NROL-44 on a Delta 4 Heavy following three months of delays and scrubs. including a pair of last-minute aborts and other delays caused by problems with the launch pad equipment.
Bruno said the problems were caused by aging equipment and difficulties operating launch pads that are rarely used.
Of the four remaining NRO missions on Delta 4 Heavy, two will fly from Cape Canaveral, Florida, and two from Vandenberg Air Force Base, California.
Bruno said ULA is taking action to avoid the problems experienced with NROL-44.
“We’re going through all the pads and preemptively replacing items,” he said. “We’ll activate the pads periodically and test them and activate them whether there’s a mission or not,” Bruno said. “I don’t expect to have issues like we had with NROL-44 ever again.”
