Sputnik weighed just under 200 lbs. The space shuttle orbiter alone weighs 240,000 lbs at liftoff. The space shuttle was very expensive and that’s part of the reason she was retired not too long ago. In the future manned flight will take a back seat to other types of exploration. It’s not over for man, but no one has the money any more to explore space the way we did before.

That’s where micro satellites come in. If you love space and astronomy, these is very exciting. In the not too distant future I can see being able to buy micro satellites for your kids and launching them in to space with a camera on them. We will always find a way to keep going into space.
