The first test mission of the US Boeing’s manned spacecraft, the Starliner, failed to dock with the International Space Station. It is the latest blow to the space giant, which has a centuries-old history and strong engineering power, in the wake of the crash. The spacecraft has now returned to Earth, and Boeing says the challenge is not over, and the accident continues to lead to Boeing’s efforts to provide NASA with manned spacecraft.
Failed docking, return to Earth
The starliner spacecraft carrying a dummy carried out its first unmanned flight test On Tuesday, taking off from Cape Canaveral Air Force Station in Florida on a United Launch Alliance carrier rocket.
However, about an hour after the launch, NASA issued a statement saying that the Starliner had not entered its intended orbit.
The spacecraft is scheduled to dock with the International Space Station on the 21st, stay for a week and return to Earth, landing in New Mexico on the 28th, but about an hour after launch, NASA said in a statement that the “Startrek” did not enter its intended orbit. the result is that it cannot be rendezvous with the space station.
The Starliner was reportedly forced to return to Earth early after docking with the International Space Station and landed at its Base in White Sands, New Mexico, at about 5:58 a.m. on the 22rd.
After the Boeing plane crash, the space problem is the software’s fault?
NASA Administrator Brendan Sting explained at a news conference that the spacecraft would have changed its orbit through “in-orbit ignition” to rendezvous with the space station, but the phase failed to go ahead as planned because the spacecraft had consumed too much fuel in unusual conditions.
He revealed that the automatic timer used to control the spacecraft’s activity misestimated the mission phase, causing the spacecraft to consume too much fuel early, and the ground control center had tried to issue an instruction to cover the timer, but because of communication delays, the command eventually failed to catch up with the fuel consumption speed, and the docking mission with the space station ran aground.
According to Boeing’s preliminary judgment, this may have been due to an error in the “data retrieval” software, which resulted in the collection of the wrong task time. Mr. Chilton, Boeing’s senior vice president of space launch, said it was unclear what was behind the spacecraft and that further judgment was needed after the spacecraft’s return, but he stressed that the problem was the software, not the spacecraft itself, and that the spacecraft’s propulsion, navigation and life support systems were operating as normal.
Boeing has been dogged by a crash scandal. In October 2018, 189 people were killed in a crash on a Lion Air Boeing 737 MAX. A few months later, an Air Asia Boeing 737 MAX also crashed, killing all 157 people on board.
Previous preliminary investigations have revealed that the 737MAX aircraft’s “mobility enhancement system” (MCAS) problems, causing the pilot to lose control of the aircraft, resulting in tragedy.
Not a complete failure Boeing: the challenge is not over
A dummy who completed his first unmanned flight test on Boeing’s Starliner is in good condition, according to NASA.
The host of the live broadcast said: “We are pleased to tell you that the dummy Rosie is in the same state as the ship when it took off, sitting in his seat in good condition.”
NASA crews said the spacecraft was in better condition than expected after its first flight, and that the surface of the spacecraft could not see any signs of burning or blackening.
NASA’s director, Bradenstein, said that although the docking failed, the mission was not a complete failure, the spacecraft successfully communicated with the International Space Station, but also in space testing berthing systems, solar panels, batteries, thrusters and thermostats.
Mr. Chilton, Boeing’s senior vice president of space, described the spacecraft’s challenge as not over, and the accident continues to lead Boeing to provide NASA with manned spacecraft.
