60 year challenge for humanity: 1969 - Moon, 2029 - Mars

Today 50 years ago first humans - 2 out of 3 Apollo 11 crew members Neil Armstrong & Buzz Aldrin - landed on the Moon. But since then the advancement of human space exploration has been slow. It changed only in recent years with the rise of private space companies, especially SpaceX with its determined focus on rocket reusability and colonization of Mars. Now we have a real chance to land first humans on Mars as soon as 10 years from now, maybe even sooner.
