Space is one of the most unexplored places in this world. The cold, dark, unbreathable environment only attracts the bravest of the bravest. And those are the astronauts. They are the Columbuses of space pushing what we know further and further. Many people died while trying to explore space. For example,Gagarin was barely saved from inevitable death as his friend volunteered to take his burden instead and was launched into space with no safe way down clearing the way for Gagarin. Many flights of NASA failed before Apollo 11 finally landed humans on the moon. And what we have explored up until now is only a tiny fraction of the big black canvas that is space.
