Virgin Orbit’s Cosmic Girl 747 aircraft conducted a low-speed taxi test down runway 12-30 at the Mojave Air and Space Port on Thursday afternoon.

The aircraft taxied down the runway, turned around and returned. The Boeing 747 was then towed back to a concrete pad where it has sat for the last several weeks undergoing preparations for a taxi test and captive carry flight.

Virgin Orbit has said that it needed to do a taxi test with a full fueled LauncherOne prior to doing a captive carry flight. It is not clear whether the booster was fueled. However, a hazardous operations notice to airmen (NOTAM) was not posted prior to the taxi test.

LauncherOne is designed to orbit small satellites by air launching them over the ocean. A flight test of the booster is scheduled for later this year.
