Project Mercury: The First Americans in Space

Project Mercury was NASA's first human spaceflight program, running from 1958 to 1963. It aimed to put a human in orbit, study the effects of space on the human body, and safely return astronauts to Earth. The program faced early challenges with unmanned missions but eventually succeeded with six manned missions, including Alan Shepard's and John Glenn's historic flights. The program's achievements laid the groundwork for future space exploration, demonstrating the ability to conduct extended missions and train astronauts effectively.
