Astronauts will remain the explorers, the pioneers-the first to go back to moon and on to Mars. But I think it's really important to make space space available to as many people as we can. It's going to be a while before we can launch people for less than $20 million a ticket. But that day is coming.

So most astronauts are astronauts for a couple of years before they are assigned to a flight.

It takes a few years to prepare for a space mission.

I would like to be remembered as someone who was not afraid to do what she wanted to do, and as someone who took risks along the way in order to achieve her goals.

Ever been to Disneyland? That was definitely an E ticket!
