Appollo is mankind’s greatest achievement in history!
We need to go further into this exploration and travel to Mars and out of our solar system! It needs to be a continuously expanding program as time goes by! There are other earths out there, in other solar systems, not to mention, in other galaxies! We are not alone, just because we don’t know of them, yet! Exploring is man’s greatest gift! Let us not be content to stay here, because one day something will destroy earth! Let mankind explore everything everywhere!
