The starship prototype SN10 is about to land.

The latest SpaceX Starship prototype is called SN11, explosive ending Last week was like its three predecessors. However, because the dense fog and malfunctioning cameras obscure the details of its ultimate fate, the surrounding environment of the Great Prosperity is unique and mysterious.

Now, the company’s founder and CEO Elon Musk has a detailed understanding of the last moments of SN11. On Twitter Monday morning, Musk attributed the explosion to a fuel leak.

He wrote: “The (relatively) small CH4 leak caused the engine 2 to catch fire and blow up some of the avionics, making it difficult to start when trying to start the CH4 turbo pump for landing and combustion.

SN11 was launched from the company’s interstellar spacecraft development center in Texas on March 30, with zero visibility on the ground. As the aircraft took off, everything went smoothly. Musk hopes to send its final version to the moon and Mars in the next few years, then ascend to about 6.2 miles (10 kilometers), and then fall back to Earth. After preparing the trademark flip action to prepare for landing burns and soft landings, the onboard camera froze during the SpaceX live broadcast.

Other remotely operated real-time cameras aimed at the landing pad from nearby, capturing an orange light in the fog, followed by stormy debris landing on the restricted area around the landing pad.

Due to the hard landing, the two early prototypes SN8 and SN9 both exploded on impact. SN10 stuck at the landing site, but then exploded After a few minutes, place it on the landing pad. SN11 appeared to explode first before hitting the ground.

Therefore, we have now sampled the way in which one of the prototypes can self-terminate during the landing phase. There are reasons to be optimistic that the next attempt will be better.

SpaceX will jump to SN15, which is reported to include a series of upgrades, and Musk is very excited about his choice to essentially eliminate SN12, SN13 and SN14.

The SN15 has been assembled and can be tested before its debut. It is hoped that one of the upcoming prototypes will not only survive the landing, but also allow the company to try its first orbital flight for Starship as soon as possible in June.

Musk said that he certainly does not want to repeat the serious leakage that caused the shrapnel scattering abnormality last week.

He tweeted: “By Sunday, there are six solutions.”
