“Creating the city of Starbase, Texas,” he wrote. “From thence to Mars, and hence the Stars,” he added.
For some context, at Boca Chica, SpaceX is working on a new type of reusable rocket called Starship. SN10, the third prototype it has tested so far, was able to make a perfect soft landing after flawlessly going through the entire sequence: liftoff, belly flop, free-fall, and landing on the spot. It exploded minutes later, but that’s a different story.
Starship will be the rocket Musk hopes to colonize Mars with. In addition to the SpaceX facility, he also has other business ventures in the state, like the Austin Gigafactory, now in construction for Tesla. Musk himself moved to Texas at the end of last year after professing his disappointment with California.
The bottom line is that it would make sense to incorporate Boca Chica, which has two dozen residents, into a new city. A statement from one Cameron County official would suggest that Musk is quite serious about it, too. In case you still thought he was tweeting for clout.
“If SpaceX and Elon Musk would like to pursue down this path, they must abide by all state incorporation statutes,” Cameron County Judge Eddie Treviño says in a statement cited by HypeBeast. “Cameron County will process any appropriate petitions in conformity with applicable law.”
Translation: it can be done, as long as it's done by the rules.
