After last-minute hiccup, United Launch Alliance booster soars away with spacecraft for National Reconnaissance Office
Clear skies provided the perfect backdrop for spectators to follow the rocket’s flight for several minutes. Groups of people with their eyes on the sky were clustered at various locations around the Central Coast.
The rocket carried a National Reconnaissance Office payload for a mission dubbed NROL-42, but the exact duties of the new spacecraft remain top secret.
Plans called for jettisoning the payload fairing, or nose cone, more than 3 minutes after liftoff.
Since an NRO payload rode aboard the rocket, officials remained mum about other key milestones, such as spacecraft separation, for the remainder of the mission.
The countdown had extra drama after a crew member declared “Hold, hold, hold,” minutes before liftoff, and the team conducted a technical recycle successfully aiming for another try at the end of the launch window.
Saturday night’s launch marked ULA’s 25th mission for the spy satellite agency since 2002.
Earlier this month, the rocket launch was delayed a week by Hurricane Irma, which was hammering Florida, and two more days by a faulty battery before getting off the ground.

“I’m not going to say it’s unusual, but it’s probably not common to have a booster at both Slick-3 and Slick-6 at the same time,” sais Lt. Col. Kenneth Decker, commander of the 4th Space Launch Squadron.
The Delta booster arrived in April so the team has supported dual operations at the two space launch complexes for months.
“I would say from a mission perspective it’s great,” Decker said. “My team is always anxious to be out there. Space launch is a lot of fun. It’s a great mission.
“To be able to go to both Slick-3 and Slick-6 on a daily basis and see the two boosters is really rewarding for the team.”
This wasn’t the only rocket launch planned in the coming weeks from Vandenberg.
That booster will carry the next 10 Iridium satellites into orbit, boosting the number to 30 for efforts to build a second-generation constellation of craft to enable communications across the globe.
Those satellites have already arrived at Vandenberg, where they are being prepped for launch.
