To add on to the answer above by Valorum, if you look over the shoulder of the African astronauts, you can see the Senegalese flag. Likely they are representatives of ECOWAS, which is an EU-like organisation (although not currently as mature) for West African states and of which Senegal is a member. I don't think the logo on their chest is a Buddha, as West Africa is religiously Christian, Muslim, and the traditional West African belief system. It appears rather to be a golden depiction of an airplane, spaceplane, or capsule of some kind, perhaps the symbol of their air force or space program.
