SpaceX finally reveals the cause of the April spacecraft explosion



SpaceX says he understands what caused one of his spaceships to explode during terrain on land in April. Valve accidentally misses part of the vehicle's fuel by starting a chain reaction that causes the spacecraft to collapse. Now that the cause is identified, SpaceX says it replaces those parts in all future versions of the vehicle to make sure that this explosive leak is not repeated.

The spaceship that lost SpaceX was a test version of the crew of the company. Dragon, a capsule that is being built for NASA to take the astronauts to and from the International Space Station. This particular capsule is the first crew dragon SpaceX has ever released in space. In March, the vehicle ̵

SpaceX immediately formed an investigation team after the incident to find out what caused the explosion and the company has been working since then. But six weeks ago, SpaceX has not yet constrained the exact cause. With the discovery of the leak, the company has already said the investigation is about 80% complete. "It's hard to say … how long we need to close this," said Hans Koenigsmann, vice president of SpaceX's buildings and flight credibility at a press conference. "But you want to make sure the capsule – everything – you want to make sure we find all the right corrective action."

The company believes that the problem stems from Crew Dragon's crew emergency crew system, which consists of a series of small pushes embedded in the capsule. If all goes well on a mission, these little pushers are never really meant to be used. But if there is any failure during a future start, the thrusters may light up and carry the Crew Dragon safely away from the disintegrating rocket. – One of the really high pressure. When this pollution occurs, the high forces slammed the liquid, causing loss of valuable components and leading to the final loss of the capsule. [96] Coenigsman said that this pollution was definitely not expected, although the type of valve that runs out is the problem of internal leakage. In the end he admitted that to a certain extent this is a matter of design. "It's something the components should not do," said Coenigsman. "But at the same time, we have learned a very valuable lesson about something that goes forward, making the Crew Dragon a safer vehicle."

"It was a huge gift for us."

SpaceX will replace all these types of valves with another component, known as the destroyed disk, which is believed to be much more reliable, according to Koenigsman. SpaceX claims there are many Crew Dragons at different stages of production at the company headquarters in California. However, it is not clear when the crew of the dragon will fly again. Before the explosion, SpaceX planned to take off its first astronauts by the end of the summer. Now SpaceX seems more likely not to fly people by the beginning of next year – although Koenigsman does not exclude a flight from 2019. "My focus is actually to make sure it's safe," he said. "So at the end of the year, I do not think it's impossible, but it's getting harder."

However, a NASA spokesman said he was grateful for the failure, especially after it happened on the ground rather than on a flight. , "We had the potential to find a hardware problem and find the hardware and appreciate the hardware," said Katie Luders, NASA's Program Manager at NASA's press conferences. " So it was a huge gift for us."
