Boeing spacecraft returned to Earth after the incident

Boeing's Starliner spacecraft landed gently in the desert in New Mexico state early in the morning on December 22.

Boeing experts ended two days of efforts to bring the Starliner back to Earth after an unexpected incident during an orbit flight. Starliner made a drone test flight on December 20 but was forced to abandon plans to pair with the International Space Station after flying off-track. Starliner's safe return flight was a success for Boeing because experts could gather useful data to evaluate the spacecraft.

Boeing took a decade to develop Starliner for manned flights. NASA asked the spacecraft design company to send astronauts to the ISS station after stopping the $ 4.2 billion space shuttle program in 2014. It was initially expected that the ship would be ready. went into operation in 2017 but experienced many delays and malfunctions.

Last week's Starliner orbit flight was the last important test before the ship was ready to fly NASA astronauts. The Starliner successfully took off from the launch pad, but after separating from the boosters, the ship did not fly the right route to the ISS station. Authorities said the cause of the train delay was delayed, causing the train to fail to fire the engine at the right time and fly out of the way.

The vehicle also lost contact with the flight control specialist for 8 critical minutes. When the communication channel was reset, the ship burned too much fuel to land on the ISS. The flight control department concluded that Starliner could not be connected to the ISS station because this task requires the ship to maintain high accuracy when approaching the laboratory flying around orbit at more than 27,359 km / h.

The ship flew through the Earth's atmosphere, opened its parachute and airbag, then landed gently.

Instead, Boeing decided to fly the Starliner on a journey back to Earth so that the spacecraft could land safely on the landing zone in Mexico. The ship flew through the Earth's atmosphere, opened its parachute and airbag, then landed gently.

Boeing and NASA will spend the next few weeks or months reviewing data, according to NASA director Jim Bridenstine. The data will include information obtained from a test dummy called Rosie mounted on Starliner with dozens of sensors to measure the acceleration force that future astronauts may experience. Authorities also need to find out the exact cause of the problem after taking off of Starliner.
