Well, we've got a campus event to celebrate the 50th anniversary of the launch of Sputnik, the Soviet satellite that started the space race between Russia and the United States on 4 October 1957. The main guest on our program is Nikita Khrushchev's youngest son, Sergei, who will talk about Sputnik, the Soviet Space program and the space race as part of the Cold War. Before he emigrated to the United States, Sergei worked as an engineer on various missile projects in Russia.
