Thought I should let people know, you can become an astronaut and still be colorblind! You are not allowed to be a pilot but there are other roles where the restrictions and more relaxed. Search up Roger Crouch. Dude’s colorblind but still went on two NASA missions as a payload specialist. She’s already following a similar path, he was a scientist for years at NASA before they allowed him to be sent up.
Don’t let your dreams be dreams, there will always be loopholes!
