space X has re-invented rocket use.
If you were to build a 747 jumbo jet, and destroy it, for every flight , seats would cost you a million dollars each.
So, they dont do that. They reuse the aircraft, and sell the same seat many times.

Space X, land their first stage rockets, and re-use them.
Thats re-inventing space travel. Making space launch affordable.

Now thats just an example, of a break through in a massive industry.

Think about smart imagining. And treatment, from a nano particle, that can find the cancer, show you were it is, and then if New phase are up to it, thermally kill it. Or maybe there are others, who will piggy back other payloads on our NPs.

Then consider the old way its done....and ask if its time for a change.

Then put a price tag on it.
