Fifty years ago, I came to the United States with $50 and a dream. I just want to thank this great nation for giving me the opportunity to contribute to your prosperity,”
wrote the scientist on Twitter.
Chang-Díaz performed seven space missions between 1986 and 2002. He was the first Costa Rican astronaut from NASA and one of the men with the most missions. He shares the record number of trips to space aboard the space shuttle.
He is also one of the members of the NASA Hall of Fame. Currently, he is developing research with a plasma engine and hydrogen projects in transportation.
