SpaceX hopes to send human beings to the moon, Mars and even further places through the “star ship” project. However, before opening a new era of space exploration, the private space enterprise still needs to constantly improve the design and good trial and error of the prototype of “star ship”. The good news is that SpaceX successfully conducted another short flight test of the SN6 prototype at Boca Chica, Texas, on Thursday. < / P > < p > through a series of base prototypes based on a single engine, SpaceX made three short flights (or “jumps”) of about 500 feet (150 meters). < / P > < p > as early as 2019, SpaceX has demonstrated tests on smaller “starhopper” prototypes. Last month, the company designed a larger version for the final orbital flight. During the period < / P > < p >, it ignited the Raptor engine, suspended the silo in the air, moved it a short distance to the side, and then achieved a soft landing. Although the landing caused a small fire, but the scene was soon put out by a large water pipe. < / P > < p > although it is not clear when SpaceX will conduct orbital flight tests, musk has previously revealed that they need to conduct a series of hop tests to better adapt to high altitude flight.
