SpaceX has a prototype available which has already had a real-life launch, which was the second video that Musk displayed. The video had been shot a few days earlier and showed rocket, which is about 10 stories tall, launching briefly, and then returning to earth after a short time. While the rocket didn’t go very far in that initial test, Musk said SpaceX plans to continue going higher and higher with each test launch.

The successful launch was due to the thrusters and landing gear that were built in, but also due to a terminal guidance system that SpaceX had developed. That technology will be used in the design of its Dragon 2 capsule, which will allow it to land anywhere on Earth with the accuracy of a helicopter.

Musk said that reusability would be the most important part of making the economics of space travel feasible. The founder of PayPal, SpaceX, and Tesla, said it was crazy to throw away rockets after each trip. “If society is going to expand beyond earth, we need to have reusable rockets,” Musk said.

He's so right about this. Why aren't more people pushing for this??

Exactly! Why aren't more people pushing for this now?

Perhaps he and Neil deGrasse Tyson should team up.

They definitely should. And Superman too!

How about the Leader of the Free World, Super POTUS?

Did you know I have a whole stash dedicated to his super suit?

Or to truncate: "If society is going to expand... we need to have reusable"

I see, that makes sense he is involved behind Space X.  Quite a story, he is, no?  Him and Dorsey, right now.
