On 5th May 1961, Shepard became the first American in space when he made a 15 minute 28 second suborbital flight in a Mercury spacecraft, and on 20th February 1962, Glenn made the first orbital flight by an American astronaut, orbiting the Earth 3 times in a flight lasting 4 hours 55 minutes and 28 seconds. In May 1963, Cooper flew the last Mercury mision, a 22-orbit flight designed to evaluate the effects on the human body of an entire day in space.
