The NASA I remember, while raising the boys just a mile from Johnson Space Center, was filled with engineers with PhD’s focusing on math and physics.  Of course, that is still true today, but with an added focus on the “whole brain”.  I love that!  First, to engage the young in the dream, using art and imaginative experiments to lure them:)  They have to want to study the hard things in the first place, or we will lose the battle for the best and brightest.   Learning to use a 3D printer to build a miniature of the shuttle, was a little miracle in itself.  Then, we built our own rockets, complete with combustible engines to lift off.  I was so proud when mine flew straight up for almost a football field before landing in the field nearby.  Who doesn’t get excited at the prospect of working beside a robot?  Especially one that is content to do the dirty work, like cleaning toilets:)  After spending 3 days soaking it all up, I am so excited for my children and grandchildren.  By the time Ivy and Hazel are my age, there will be a colony on Mars, don’t doubt it!  Who knows what else?
