Virgin Galactic said the pin does not support the weight of the spaceplane during the climb to altitude.
Virgin Galactic Holdings Inc. experienced an in-flight hardware issue during its most recent crewed space tourism flight, the Richard Branson-founded company said on Monday.
A pin used to align Virgin Galactic’s spaceplane, VSS Unity, and its carrier aircraft, VMS Eve, while both vehicles are mated on the ground later became detached during the Jan. 26 flight. Virgin Galactic said the pin does not support the weight of the spaceplane during the climb to altitude.
“At no time did the detached alignment pin pose a safety impact to the vehicles or the crew on board,” the company wrote in a statement.
The company didn’t specify a cause of the pin malfunction. It noted that the pin became dislodged after VSS Unity had been deployed, when the pin no longer served any active function for the remainder of the flight.
Virgin said it caught the issue during routine post-flight reviews and notified the Federal Aviation Administration on Jan. 31. It is conducting a review together with the FAA, the company added. An agency spokesperson didn’t immediately respond to a request for comment.
Virgin Galactic kicked off commercial spaceflight operations in 2023 after nearly two decades of development. Since then, the company has performed six tourist and research flights that have carried customers to the edge of space and back.
Virgin Galactic has grappled with in-flight issues over the years. When the company famously flew founder Branson to space in 2021, the spaceplane deviated from its intended flight path, prompting a mishap investigation overseen by the FAA. In 2014, a Virgin Galactic operated spaceplane crashed when its wings shifted prematurely midflight, causing the death of one test pilot and injuring another pilot.
Virgin Galactic said it will provide further updates and confirm the timing of its next mission – currently planned between April and June – after its review with the FAA.
The review comes amid heightened scrutiny of the FAA and the aerospace industry in the wake of the fallout from manufacturing issues with Boeing Co.’s 737 Max 9 jets.
However, the FAA is prohibited from mandating safety standards on commercial spacecraft that fly humans to space, though this legislative moratorium is set to expire on March 8.
Virgin Galactic’s Jan. 26 flight was the first time the company sent four tourists to space without a Virgin Galactic astronaut acting as support staff.
