How to grow a generation of space explorers

Look at this few seconds from the already legendary Falcon Heavy first launch.

If you follow Musk, you'll remember this excerpt from Elon Musk biography:

A consensus started to build around pursuing a different project—something called “Mars Oasis.” Under this plan, Musk would buy a rocket and use it to shoot what amounted to a robotic greenhouse to Mars. A group of researchers had already been working on a space-ready growth chamber for plants. The idea was to modify their structure, so that it could open up briefly and suck in some of the Martian regolith, or soil, and then use it to grow a plant, which would in turn produce the first oxygen on Mars. Much to Musk’s liking, this new plan seemed both ostentatious and feasible.
Musk wanted the structure to have a window and a way to send a video feedback to Earth, so that people could watch the plant grow. The group also talked about sending out kits to students around the country who would grow their own plants simultaneously and take notice, for example, that the Martian plant could grow twice as high as its Earth-bound counterpart in the same amount of time. “This concept had been floating around in various forms for a while,” said Dave Bearden, a space industry veteran who attended the meetings. “It would be, yes, there is life on Mars, and we put it there. The hope was that it might turn on a light for thousands of kids that this place is not that hostile. Then they might start thinking, Maybe we should go there.”

I emphasized what I think is one of the less evident goals of yesterday launch.
It was rocket test, but also a publicity stunt: for SpaceX services, for the new suit, for Tesla cars. It was a funny thing to do.
But it was also a great way to inspire people, yet again, that we can explore the space.
They are indeed planting a seed: in the hearth of young earthlings.
