The space exploration technology company starship SN8 exploded during the flight test landing. What caused the explosion?

Event Review: At about 6: 30 on February 9th, Beijing time, the prototype SN8 of the starship of Space Exploration Technology Company made a test flight at the altitude of 12.5km in Texas, USA. 0.3 seconds before the launch of 65438+, SN8 self-inspection system detected one or more abnormalities in three Raptor engines, automatically stopped the launch, and re-launched after a series of inspections. The video shows SN8' s epic flight and explosive ending. Musk later said that during the landing of the spacecraft, the pressure of the head fuel tank was low, resulting in a faster landing speed. But we have got all the data we need. Congratulations to the team of Space Exploration Technology Company! Musk had previously predicted that the probability of successful launch and landing was only one-third. ?

In the 12.5Km altitude test of starship SN8, three raptor engines installed on starship SN8 stopped after launching about 100S. In the end, the starship SN8 has only one engine working, one engine has reached the limit full thrust, and the starship SN8 has reached the flight goal of 12.5km. However, in the end, during the landing of the starship SN8, a raptor engine stopped and lost power, which led to the low reverse thrust of the starship SN8 and failed to fully slow down, leading to the explosion of the starship SN8 when landing. Although it exploded during landing, the explosion hardly damaged the facilities of the launch site. ?

According to the data,? Starship? It integrates spacecraft, rockets and landers and plans to transport people and goods to deep space destinations. And Musk has publicly expressed hope? Starship? In the future, it can be used to transport satellites, travel around the world and immigrate to Mars. According to the website of space exploration technology company, this? Starship? Will it be more than the existing one? Falcon? Put the satellite into orbit at a lower cost. In fact, Musk's expectations of the prototype SN8 are not too high, so only the landing link has a problem, which is considered to be a successful test, exceeding the expectations of space exploration technology companies and most professional observers. Space exploration technology company hopes that the final starship can realize the mission of human flying to the moon and Mars at low cost, and realize Musk's wish to let one million people immigrate to Mars.

Failure is the mother of success. No failure, no success. I hope China's space department can learn from the failed experience of space exploration technology company and accumulate experience.
