The flight to a height of about 10 kilometers is to take place today or tomorrow just after midnight. The launch of the SN9 prototype will take place from the company's test facility in Boca Chica, Texas. Currently, there are already two prototypes in the facility, namely SN9 and SN10, and more versions are being assembled in a nearby factory.
SpaceX announces that shortly after the SN9 flight, engineers will start data analysis and simultaneously conduct cryogenic and static tests of the SN10 prototype. Both vehicles are equipped with 3 powerful Raptor engines. Ultimately, Starship will have 6, and the SuperHeavy rocket as many as 31. The first flight of the full-size Starship may take place after the holidays.
In addition to working on the vehicle prototypes, SpaceX will start modernizing recently purchased oil rigs, which will eventually become the offshore launch pads for the most powerful space transportation system in human history. The platforms web engineering named Phobos and Deimos. Yes, you are right, all this is for the moons of Mars.
