On September 3, the Federal Aviation Administration (FAA) announced on Thursday that it had ordered the space tourism company virgin galaxy to grounded the SpaceShipTwo spacecraft until it completed its investigation on the yaw problem in its first manned space flight p> < p > FAA said in a statement: "Virgin Galactic cannot allow SpaceShipTwo spacecraft to fly again until FAA approves the final accident investigation report or determines that the problems related to the accident do not affect public safety." p> < p > the agency added: "the FAA is responsible for protecting public safety during commercial space transport launches and re-entry operations. We are overseeing Virgin Galactic's investigation into the SpaceShipTwo accident over Spaceport America, New Mexico, on July 11. At that time, SpaceShipTwo deviated from the route when returning to the U.S. space port. " p> < p > in the process of sending the crew, including founder Richard Branson, to the edge of space, Virgin Galactic's mission called unity 22 was not as perfect as it seemed in the live broadcast. During liftoff, when SpaceShipTwo engine is ignited, yellow and red warning lights are on. These warning lights show that the vertical lift-off of the spacecraft is not high enough to glide back freely with enough momentum after reaching space p> < p > when the spacecraft returned, it deviated from the air traffic control airspace, prompting the FAA to intervene in the investigation. The FAA confirmed in a statement that the spacecraft "deviated from the route" and flew outside the designated airspace for 1 minute and 41 seconds p> < p > the first manned flight on July 11 is the most critical marketing activity of Virgin Galactic, which proves that the company's spacecraft can safely send paying customers into space. However, when Branson and others returned to the ground to celebrate, no one mentioned the deviation of the spacecraft from the route, warning lights and other issues, and Virgin Galactic did not even report the matter to the FAA. The company later admitted that it did not report to the FAA at first, but is now cooperating with the agency to prevent similar situations from happening again p> < p > the new Yorker magazine first reported the problem during Branson's space trip on Wednesday and stressed people's concerns about Virgin Galactic technology and safety culture, which was highlighted by the recent resignation of flight test director Mark "forger" Stucky. It is said that Starkey has repeatedly warned about the safety of the company's flight test inside virgin galaxy p> < p > however, Virgin Galactic has refuted the "misleading description and conclusion" in the new Yorker article through a statement. A spokesman for the company said: "we take this matter seriously. At present, we are looking for the cause of the problem and determining how to prevent this situation from repeating in future tasks." He reiterated that the crew had never encountered any danger during the flight, "we have been working closely with FAA to support a thorough review and timely resolution of this problem" p> < p > Virgin Galactic confirmed that SpaceShipTwo did fly out of the FAA protected airspace, but said that the agency's Representatives "appeared in our control room during and after the flight". The spokesman added: "passengers and crew will not be in danger at any time due to route changes. Although SpaceShipTwo's flight trajectory was pushed away by the wind, our pilots responded appropriately. " p> < p > Branson also personally responded that FAA's investigation "has no impact on future test flights". Virgin Galactic plans to conduct its next space flight test at the end of September or early October. The plane carries six people, including two pilots and four passengers p> < p > initially, after the new Yorker published a document on Wednesday, the FAA only said that it was investigating the incident. But on Thursday morning, Virgin Galactic released a press release announcing the next space flight test crew called unity 23, including three members of the Italian air force. A few hours later, the FAA issued the latest statement requiring Virgin Galactic to grounded SpaceShipTwo before the problems related to the unity 22 flight are solved p> < p > Virgin Galactic shares rose 5% in earlier trading, but fell 3% to close at $25.99 after the FAA announced the news( Small) < / P > < p >
