ULA launches second Vulcan flight, encounters strap-on booster anomaly
United Launch Alliance fired off a next-generation Vulcan rocket Friday in the second of two “certification” test flights needed before the new launcher can be used to carry high-priority national security payloads for the U.S. Space Force and the National Reconnaissance Office. One of two solid-propellant strap-on boosters provided by Northrop Grumman suffered an anomaly of some sort. ULA CEO Tory Bruno said it will be investigated.
