The South Texas home of Elon Musk’s SpaceX rocket company is now an official city with a galactic name: Starbase.

The decision to officially establish Starbase as a city received overwhelming support from the limited group of residents, who primarily consist of SpaceX employees working under Musk.

With all the votes in, the tally was 212 in favour to 6 against, according to results published online by the Cameron County Elections Department.

Musk celebrated in a post on his social platform, X, saying it is “now a real city!”

Starbase serves as the development and launch site for the SpaceX rocket program, which holds contracts with the Department of Defence and NASA, aiming to return astronauts to the moon and ultimately journey to Mars.

Musk proposed the concept of Starbase in 2021, and the approval of this new city was practically inevitable. Among the 283 eligible voters in the vicinity, the majority are presumed to be Starbase personnel.

The election victory was personal for Musk. The billionaire’s popularity has diminished since he became the chainsaw-wielding public face of President Donald Trump’s federal job and spending cuts, and profits at his Tesla car company have plummeted.

SpaceX has generally drawn widespread support from local officials for its jobs and investment in the area.

But the creation of an official company town has also drawn critics who worry it will expand Musk’s personal control over the area, with potential authority to close a popular beach and state park for launches.

Companion efforts to the city vote include bills in the state Legislature to shift that authority from the county to the new town’s mayor and city council.

All these measures come as SpaceX is asking federal authorities for permission to increase the number of South Texas launches from five to 25 a year.

The city at the southern tip of Texas near the Mexico border is only about 3.9 square kilometres, crisscrossed by a few roads and dappled with airstream trailers and modest mid-century homes.

SpaceX officials have said little about exactly why they to want a company town and did not respond to emailed requests for comment.

“We need the ability to grow Starbase as a community,” Starbase General Manager Kathryn Lueders wrote to local officials in 2024 with the request to get the city issue on the ballot.

The letter said the company already manages roads and utilities, as well as “the provisions of schooling and medical care” for those living on the property.

SpaceX officials have told lawmakers that granting the city authority to close the beach would streamline launch operations. SpaceX rocket launches and engine tests, and even just moving certain equipment around the launch base requires the closure of a local highway and access to Boca Chica State Park and Boca Chica Beach.

Critics say beach closure authority should stay with the county government, which represents a broader population that uses the beach and park. Cameron County Judge Eddie Trevino jnr has said the county has worked well with SpaceX and there is no need for change.

Another proposed bill would make it a Class B misdemeanor with up to 180 days in jail if someone doesn’t comply with an order to evacuate the beach.

The South Texas Environmental Justice Network, which has organised protests against the city vote and the beach access issue, held another demonstration Saturday that attracted dozens of people.

Josette Hinojosa, whose young daughter was building sandcastle nearby, said she was taking part to try to ensure continued access to a beach her family has enjoyed for generations.

With SpaceX, Hinojosa said, “Some days it’s closed, and some days you get turned away.”

Organizer Christopher Basaldú, a member of the Carrizo/Comecrudo Nation of Texas tribe, said his ancestors have long been in the area, where the Rio Grande meets the Gulf.

“It’s not just important,” he said, “it’s sacred.”
