One of the powerful rocket engines according to CNBC BE-4 Blue Origin suffered a major malfunction during testing last month. BE-4 The engine to power Blue Origin’s New Glenn rocket and United Launch Alliance (ULA’s) Vulcan Centaur is about 10 seconds after a June 30 test at Blue Origin’s West Texas facility, CNBC’s Michael Sheetz reported. Exploded. Tuesday (11 July).

Sheetz wrote that people familiar with the anomaly “had seen video of a dramatic explosion that destroyed the engine and severely damaged the testbed’s infrastructure.” Sheetz wrote that the engine was preparing for flight during the second launch of the Vulcan Centaur. Blue Origin confirmed this detail and test event in a statement to CNBC.

According to Sheetz, Blue Origin officials said, “No personnel were injured and we are currently assessing the root cause.” The statement said that investigators have already determined the approximate cause of the anomaly and are working to eliminate actions.

Blue Origin added that it immediately reported the incident to ULA. The latest company, a joint venture between Boeing and Lockheed Martin, doesn’t seem to see this as a serious issue at the moment.

ULA President and CEO Tory Bruno stressed on Twitter on Tuesday that the BE-4 is already suitable for flight, which means its overall design is solid. The engine, which failed on June 30, was undergoing an “acceptance test” (APT) before flight, looking for problems in individual units. (There are other steps along the way, including a hot-fire test of fully integrated engines on the launch pad.)

“ATP failures are not uncommon. That’s why we do them on every single serial number that comes off the line,” Bruno said in another tweet on Tuesday.

ULA is dealing with its own problems on Vulcan Centaur. The heavy lifter would make its debut in early May with a mission to send the special Peregrine lander to the moon. But that target date was delayed after the Centaur’s upper stage exploded during a test at NASA’s Marshall Space Flight Center on March 29.

It is not yet known when the new rocket will take off. Late last month, the company said it would dismantle the first Vulcan Centaur and return the upper stage to its factory in Alabama for modifications. We’ll find out more soon: Bruno is scheduled to talk to reporters about the Vulcan Centaur on Thursday, July 13.

The other big rocket the BE-4 will use, New Glenn, has not yet flown. Its debut was originally scheduled for 2020, but delays in the development of the BE-4 have repeatedly pushed that schedule to the right. Sheetz noted that Blue Origin has declined to give a new end date any time soon.
