On Jan. 31, 1961, HAM the chimpanzee made history as the first of his kind to travel in a spaceship.
HAM, which stands for Holloman Aerospace Medical Center, traveled aboard a Mercury Redstone rocket on a sub-orbital flight for NASA.
HAM made his trip just three years after the formation of the National Aeronautics and Space Administration on Oct. 1, 1958.
