In the exploration of space many different countries have gone to many different places in space. From Astro 1 and 2, with the "Astro Observatory", to Neil Armstrong, from the United States was the first man to walk on the moon. But before all of the these exciting projects begin there hours and hours of training that go through. An excerpt from and article on NASA's site says "First, you must learn how to put on your 127-kilogram (280-pound) spacesuit -- it will provide you with the air you need to breathe while you're outside your spacecraft. It will also keep your body at a comfortable temperature even though it may be 200 degrees below zero to 200 degrees above zero outside." This is just one small piece of training need to go onto a space journey. Exploration out into space has a large connection to history and we have had major discoveries over these past decades.
