KENNEDY SPACE CENTER, Fla. — United Launch Alliance’s Vulcan Centaur soared into night skies on its long-awaited first launch Jan. 8, carrying a commercial lunar lander.
The Vulcan Centaur lifted off from Cape Canaveral’s Space Launch Complex 41 at 2:18 a.m. Eastern on a mission designated Cert-1 by ULA. The primary payload of the Cert-1 mission, Peregrine, was deployed from the Centaur upper stage 50 minutes later after two burns of the Centaur upper stage. A second payload, from space memorial company Celestis, remained attached to the Centaur as planned.
Peregrine is a lunar lander developed by Pittsburgh-based Astrobotic. The Centaur placed Peregrine on a highly elliptical orbit that will take it to the moon, where it will go into orbit in advance of a landing attempt Feb. 23.
Peregrine is carrying 20 payloads, including five from NASA as part of the agency’s Commercial Lunar Payload Services (CLPS) program. NASA is paying $108 million for the payload delivery. Other customers include national space agencies, companies and organizations flying payloads ranging from miniature rovers to commemorative items.
Peregrine is Astrobotic’s first lunar lander after 16 years of work. “It’s just a massive mix of emotions,” said John Thornton, chief executive of Astrobotic, in a Jan. 5 interview. “We’ve overcome so many reasons that we shouldn’t be here.”
Once Peregrine is powered up and checked out after separation, the next major milestone is a series of trajectory correction maneuvers a few days after launch. Peregrine will later go into lunar orbit, gradually lowering that orbit to prepare for the landing near Gruitheisen Domes on the near side of the moon.
Thornton acknowledged the mixed track record of lunar landers, with a historic success rate of less than 50%. “We know we’re headed into a gauntlet here. We know we’re headed into very difficult territory,” he said. “At the end of the day, we need to get…
