Russian cosmonaut Yuri Gagarin was the first man in space in 1961, and American astronaut Neil Armstrong was the first to walk on the Moon in 1969. The document discusses how humans have achieved traveling to space and the Moon, and some believe the next step is for humans to visit Mars. Many astronauts would welcome the opportunity to be the first person to walk on Mars and gain such fame, but the document raises the question of what the experience of space travel is really like for those who embark on these missions.
