FAA grounds SpaceShipTwo after problem on July flight

LOMPOC, Calif. — The Federal Aviation Administration won’t enable Virgin Galactic to renew flights of its SpaceShipTwo suborbital spaceplane till it completes an investigation into an issue on the automobile’s earlier flight in July.

In a Sept. 2 assertion, the FAA mentioned it’s overseeing a Virgin Galactic mishap investigation into the July 11 flight of SpaceShipTwo, known as “Unity 22” by the corporate, which appeared to go as deliberate however the truth is suffered an issue that brought on it to stray from its restricted airspace.

“Virgin Galactic could not return the SpaceShipTwo automobile to flight till the FAA approves the ultimate mishap investigation report or determines the problems associated to the mishap don’t have an effect on public security,” the company acknowledged.

The assertion got here a day after the publication of an article by The New Yorker that exposed that the 2 SpaceShipTwo pilots ignored an “entry glide cone warning” throughout the July 11 flight from Spaceport America in New Mexico. The flight took them and 4 others on board, together with Virgin Galactic founder Richard Branson, to the sting of area and again with no indication on the time of any issues.

That warning indicated that the automobile was exterior the amount of area often called the glide cone the place it had sufficient power to glide again to a runway touchdown on the spaceport. The warning appeared late within the powered portion of the flight, indicating that the automobile was not climbing steeply sufficient.

Firm sources cited within the article mentioned that, within the occasion of such a warning, SpaceShipTwo’s hybrid rocket motor ought to have been shut down, aborting the flight. As a substitute, the pilots, David Mackay and Mike Masucci, let the motor hearth for the total length. An abort may have prevented SpaceShipTwo from reaching the 80-kilometer altitude that the corporate defines as area, thwarting Branson’s bid to get to area earlier than Blue Origin founder Jeff Bezos did so on his firm’s New Shepard suborbital automobile July 20.

Throughout SpaceShipTwo’s glide again to the runway at Spaceport America, it flew for a time exterior of its designated airspace, based on flight monitoring knowledge. The automobile landed safely.

In a Sept. 1 assertion, Virgin Galactic mentioned it disputed “the deceptive characterizations and conclusions” of the article. Nevertheless, it did acknowledge that SpaceShipTwo “did drop under the altitude of the airspace that’s protected for Virgin Galactic missions for a brief distance and time,” which it estimated at 101 seconds.

Virgin Galactic blamed excessive winds at higher altitudes for the deviation in trajectory that triggered the warning. “Our pilots responded appropriately to those altering flight situations precisely as they had been skilled and in strict accordance with our established procedures,” the corporate mentioned. “Though the flight’s final trajectory deviated from our preliminary plan, it was a managed and intentional flight path that allowed Unity 22 to efficiently attain area and land safely at our Spaceport in New Mexico.”

The previous director of Virgin Galactic’s take a look at flight program criticized the corporate. “Essentially the most deceptive assertion right this moment was @virgingalactic’s,” tweeted Mark “Forger” Stucky. “The information are the pilots did not trim to attain the correct pitch charge, the winds had been properly inside limits, they did nothing of substance to handle the trajectory error, & entered Class A airspace with out authorization.”

Stucky, who piloted SpaceShipTwo on its first suborbital spaceflight in December 2018 and had been an inner critic of some flight take a look at practices on the firm, was let go by Virgin Galactic every week after the July 11 flight.

Hours earlier than the FAA assertion, Virgin Galactic introduced plans for its subsequent SpaceShipTwo flight. The Unity 23 flight might be a devoted flight for the Italian Air Pressure carrying three Italian researchers and one Virgin Galactic worker within the cabin. The flight might be piloted by Masucci and CJ Sturckow. Unity 23 is the final earlier than the corporate goes right into a upkeep interval for each the spaceplane and its WhiteKnightTwo plane scheduled to run to the center of 2022.

“Being chosen by the Italian Air Pressure to assist their microgravity analysis is a testomony to the distinctive scientific capabilities of our spaceflight system,” Michael Colglazier, chief government of Virgin Galactic, mentioned in a Sept. 2 firm assertion. “This flight might be remembered as an vital milestone in unlocking the transformative potential of repeatable and dependable entry to area for years to return.”

The Virgin Galactic announcement made no point out of the mishap investigation, however acknowledged it anticipated to carry out the Unity 23 mission in late September or early October. The FAA didn’t disclose when it anticipated to present its approval for the corporate to renew flights.
