I don’t know if they have any but they surely must have something.
My Dad was in the space industry in So California when LBJ channeled mission control to Houston and the industry there was ticked.
And ticked for good reason. Huge amounts of money was spent so that LBJ could move the jobs from California and Florida to Houston which up to then had nothing to do with the space industry other than LBJ being president (and a stinking one at that). It was and is a bad and very expensive joke. If Houston isn’t happy about it they should show some class and ask the jobs to move back where they came from (and never should have left).
Space Center Houston (the public museum) has a Saturn V rocket (was going to be Apollo 18 before the program was cancelled), A Mercury craft, the forward (crew) section of one of the Gemini capsules, and the Command Module from Apollo 17, the last fight to go to the Moon. They also have the life-size trainer module for Skylab.
Even though they have all that...I still think Houston should have gotten a Shuttle. That bastard Obama just wanted to be petty and hateful because Texans don’t like him or his policies.
