Wade at night into the gently lapping surf at Boca Chica Beach, an undeveloped stretch of sand about 20 miles east of the Texas border town of Brownsville, and ahead you’ll see nothing but Gulf waters meeting sky—endless, dark but for the stars and languid whitecaps. A pensive, ancient view to make you feel small and the world enormous.
Turn around and everything inverts. Beyond a smattering of working-class Latino families, gathered around bonfires and pickup trucks on the beach, looms something brimming with novelty, brightness, and ambition: the South Texas launch site for SpaceX, where one day a 400-foot rocket may leave Earth en route to Mars.
