SpaceX’s Starship test is still difficult to make progress. After the failed landings of SN8, SN9 and SN10, SN11 has also stepped up in the footsteps of its predecessors today, but it did not even reach the landing and broke up in the air. The reason for the disintegration is still in a cloud of mystery-this is not a rhetorical method, but when the SN11 was launched for testing, the area was really filled with a thick layer of fog, making it impossible for all ground cameras to shoot. The launch and explosion process of SN11.
The SN11 itself is equipped with a lot of camera lenses, but the signal was lost at the time of the crash, so unless it can be found and recovered in the wreckage, it is probably difficult to see what is coming.Musk said afterwards, At least “the impact crater is in the correct position”, which means that the SN11 should not deviate from the established track. Then the second engine has problems during the ascent and the pressure is insufficient during landing, but “theoretically, the second engine is not needed. Able to complete the landing.” The detailed cause of the crash can only be concluded after SpaceX inspects the wreckage.
After that, Musk also answered some questions about Starship’s next test plan. First of all, the BN1 lower-stage rocket, which has been almost completed, seems to not be pushed to the launch pad and directly enters the scrap iron recycling plant.Musk says BN2 has undergone a lot of design changes, and it is currently planned to push the BN2 with the engine onto the launch pad before the end of April. He also said, “If you are lucky, BN2 may even have the ability to enter orbit.” It is obvious that SpaceX seems to be planning to launch BN2 into the air, or even fill it up and launch it into orbit.
As for the Starship side,SN15 will appear next, Will leave the factory for the launch pad in “a few days.” SN15 is a major change, with hundreds of design improvements in terms of structure, instruments, software, and engines. Musk hopes that these changes can directly solve the deficiencies that caused the SN11 crash. If not, SN15 will probably take a few more days to modify. Further on,SN20 is the next major design changeStarting from this prototype, it will have the ability to connect and separate from the Superheavy lower-level rocket, and it will have a full set of insulation bricks. Musk believes that the success rate of the SN20 rocket launch should be high, but I am afraid that many test aircraft will have to be destroyed to survive the high heat of the return atmosphere and land.
