We send space shuttles to the moon and Mars but we know so little about our own planet.

There are tremendous changes happening in the environment but nobody really knows where it all is going. And the reason is that we don't know how major eco-systems such as oceans work,

That's no moon. It's a space station.

The greatest fallout of the space program, ... was not the close-up view of the moon, but a look at spaceship Earth from afar. For the first time in the history of humanity, we were able to see our planet for what it really is.

The moon buggy is lighter in space because there's less gravity there.

Man is now able to soar into outer space and reach up to the moon; but he is not moral enough to live at peace with his neighbor!
