When I was a kid, the idea of space travel and finding other worlds was fantasy. Thanks to television shows, it started seeming possible. Then, on 20 Jul 1969, it was real. Over these past 40 years, we've become rather blase about space travel, missions to Mars and explorations beyond our star system.
Right now, as you read this, an American shuttle is in space on a mission to fix the Hubble Space Telescope (pictured). I don't know about you, but I think this is amazing stuff. I mean, think of it: human beings floating in space thousands of miles above the surface of the earth. Isn't that amazing? (Of course, I am amazed that planes can actually fly.)
However you feel about the amazing advances in space, you can read a current update on the work here, and see images from the Hubble here.
