SpaceNews reports that Virgin Orbit’s LauncherOne failed on its maiden flight due to a break in a propellant line. CEO Dan Hart revealed the cause of the failure on Wednesday.
“We had a component break in our engine system. It was a high-pressure feed line,” he said. Liquid oxygen “stopped going into the engine and our flight was terminated.”
The company has performed an investigation and identified what needs to be fixed in the engine to strengthen the components that failed. A second LauncherOne rocket is in final integration right now and will be leaving the factory in the next few weeks while modifications to the engine continue. “We’ll be targeting our next flight before the end of the year,” Hart said.
LauncherOne fired for about four seconds before the engine shut down. The rocket had been dropped from a modified Boeing 747 jetliner.
