United Launch Alliance's Vulcan rocket, under contract for dozens of flights for the US military and Amazon's Kuiper broadband network, lifted off from Florida on its second test flight Friday, suffered an anomaly with one of its strap-on boosters, and still achieved a successful mission, the company said in a statement.
This test flight, known as Cert-2, is the second certification mission for the new Vulcan rocket, a milestone that paves the way for the Space Force to clear ULA's new rocket to begin launching national security satellites in the coming months.
While ULA said the Vulcan rocket continued to hit its marks during the climb into orbit Friday, engineers are investigating what happened with one of its solid rocket boosters shortly after liftoff.
After a last-minute aborted countdown earlier in the morning, the 202-foot-tall (61.6-meter) Vulcan rocket lit its twin methane-fueled BE-4 engines and two side-mounted solid rocket boosters to climb away from Cape Canaveral Space Force Station, Florida, at 7:25 am EDT (11:25 UTC) Friday.
A little tilt
As the rocket arced east from Cape Canaveral, a shower of sparks suddenly appeared at the base of the Vulcan rocket around 37 seconds into the mission. The exhaust plume from one of the strap-on boosters, made by Northrop Grumman, changed significantly, and the rocket slightly tilted on its axis before the guidance system and main engines made a steering correction.
Videos from the launch show the booster's nozzle, the bell-shaped exhaust exit cone at the bottom of the booster, fall away from the rocket.
"It looks dramatic, like all things on a rocket," Bruno wrote on X. "But it’s just the release of the nozzle. No explosions occurred."

The Federal Aviation Administration said it was aware of the booster issue, adding, "no public injuries or public property damage have been reported. The FAA is assessing the operation and will issue an updated statement if the agency determines an investigation is warranted."
