SpaceX billionaire Elon Musk travels to the Texas Capitol as the state tries to make the Rio Grande Valley the newest launch site for private space flights.
Lawmakers say Texas is competing with Florida and Puerto Rico for a commercial SpaceX spaceport.
Anthony Gray, who's an aide to Democratic state Rep. Rene Oliveria, said Musk on Friday is to attend a House Appropriations Committee meeting.
Oliveria represents the Brownsville area, where the proposed SpaceX site would be situated. He filed legislation earlier this week that would allow the state to temporarily close South Texas beaches for launches and space flights.
Oliveria has previously said the state has pledged $3.2 million toward enticing SpaceX.
Musk also is to deliver a keynote speech Saturday at the South by Southwest festival in Austin.
