Atlantis Revisited

Despite spending 3 days here last year we returned to Kennedy Space centre again today. We just had to visit Atlantis again. I still can't get over the speed of progress those people made from sending Ham the chimp into orbit on my 1st birthday to sending a man into space a few months later- Alan Shepherd in May 1961 then walking on the moon in July 1969. What will happen in the next 30 years?
