We should have them, both as celebration of what he did, and to make people more aware that the first black man in space wasn't actually from the US. I got into a dumbass argument over who the first black person in space was, and every fucking search engine was giving Guy Bluford, the first African American in space, as the only result unless you get specific (the wiki for Bluford even states he's the second person of African descent, but then doesn't specify ATM), and I was struggling to remember what his name was off the top of my head.
