Space is the final frontier.. its important for us to continue exploration. Just like how Christopher Columbus travel across the Atlantic in search of new world.. exploration is exciting, it opens new opportunities.

Our progress has been small.. the farthest we've gone to is to the moon.. with some efforts now to go further to Mars..

It is important for space exploration to continue..because it is what propels space technology. The efforts now should now be geared towards improving space technology in order to prevent future catastrophe like comet/meteor threats to earth and global warming. This is more important than any mission to mars or discovering whatever "earth like" planets.
