Conserve Earth, Colonize Space

Had a bumper sticker by that title, years ago. Back in the 80s, I believe it was, when talk of O’Neil’s orbiting colony at L-5 (left) was rather more popular than now.

But it should be, again, in some form, avers aerospace guy Rand Simberg. Exploration, per se, makes no sense. Unless we go to stay.

And if we don’t do it, others will.

More ideas, here.
