Musk was joined today by Gov Rick Perry and other officials as SpaceX broke ground at the state's southernmost tip.
The ceremony marked the start of construction of the USD 85 million site at Boca Chica Beach, east of Brownsville, where commercial satellites will be launched.
Perry is providing USD 2.3 million from the Texas Enterprise Fund toward the project and another USD 13 million from the Spaceport Trust Fund to pay for infrastructure.
The company already has a rocket testing facility in McGregor in Central Texas that employs 250 people.
