A dislodged fuel filter caused last month’s failure of the first attempt to launch satellites into orbit from the UK, Virgin Orbit has said. This caused an engine to overheat, leading to the malfunction of components and the premature shutdown of the LauncherOne rocket’s thrust, according to the company founded by billionaire Sir Richard Branson. The rocket components and payload then fell back to Earth within the approved safety corridor in the Atlantic Ocean without achieving orbit.
Virgin Orbit said in a statement: “The data is indicating that from the beginning of the second stage first burn, a fuel filter within the fuel feedline had been dislodged from its normal position.” Chief executive Dan Hart said: “In space launch, a failure is painful for all involved. Intense disappointment gets quickly channelled into the motivation to dig into the cause, to understand all contributing elements and to thereby get back to flight with a better system and a wiser team.
“Our investigation is not yet complete; the team is hard at work and we’ll pursue the cause and contributors to wherever the system analysis takes us. However, with many clear clues from extensive data assessment now understood, we are modifying our next rocket with a more robust filter and we are looking broadly to assure that all credible contributors to mission failure are rooted out and addressed.
