Although boccachka factory had parts marked "SN20" as early as March 2021, the development of SpaceX's first interstellar spacecraft that can enter earth orbit definitely started in mid June this year, when engineers assembled the first engine part with a bracket that can hold six Raptor engines < p > however, according to SpaceX's usual practice of maximizing the speed of starship development, companies often manufacture starship parts in batches before distributing them to any prototype, booster or tank. In other words, there is always a certain degree of uncertainty before SpaceX actually starts assembling multiple completed rocket parts. But SpaceX started assembling the Starship prototype S20 earlier this month, and the super heavy booster No. 4 may be following < p > in mid May this year, SpaceX moved the spaceship prototype sn16 to an open space, and only in the first week of July did it begin to assemble the parts of the spaceship prototype. Before that, the company spent seven months in manufacturing and testing, manufacturing and testing SN8, sn9, Sn10, sn11, sn15, and testing tanks sn7.2 and bn2.1. Just as sn15 became the first prototype of a successful high-altitude test flight and successful landing, it was reported that SpaceX is expected to complete its first orbital flight test with S20 and B3 in July this year On July 14, it was reported that "the flap and thrust parts of S20 were assembled earlier today. That leaves a pile of parts that will be assembled into tanks, a pile of parts that will be assembled into nose cones and four nose rings, and the last pile of parts that will be used to assemble nose cones and hull together. " < p > finally, the orbital launch mission of booster 3 will be completed by booster 4, but the Starship prototype S20 remains. The time interval of nearly two months from sn16 to S20 is likely due to the significant changes and upgrades of S20 < p > S20 has three Raptor engines operating in space and three Raptor engines igniting in the earth's atmosphere for spacecraft landing. In addition to the thrust structure that can run six Raptor engines, the S20 also needs thousands of complete heat shields; Communication and Avionics for orbital flight, etc At present, about half of the assembly work of S20 has been completed. The final part of the spacecraft's fuel tank is ready for installation, and the S20 nose cone is in the late stage of assembly. But SpaceX hasn't completely covered the nose cone with insulating tiles, and it may take one or two attempts to complete the process correctly At the same time, the assembly of booster 4 may have started on July 15. All in all, the first orbital class starship prototype and the super heavy booster prototype will be fully assembled and ready for testing sometime this August（ Chen Chen) < / P > < p > 1
