It Takes A Few Years To Prepare

Anything From Making A Mistake On An Experiment That Would Ruin Some Scientist On Earth's Experiment - Career, Potentially - To Doing Something Wrong With The Satellite That A Country Was Depending On For Its Communications, To Making Some Mistake That Could Actually Cost You And The Crew Either A Mission Or Your Lives. So There Is A Lot Of Pressure That's Put On Every Astronaut To Just Make Sure That He Or She Understands Exactly What To Do, Exactly When To Do It, And Is Trained And Prepared To Carry It Out.

So I Decided On Science When I Was In College.

You Can Picture Pretty Easily If There Were A Paying Passenger Aboard A Rocket That Failed, Like Challenger Failed. Certainly It Would Be A Tragedy, And A Tragedy For The Company. They Would Have A Hard Time Recovering From It.

I Liked Math - That Was My Favorite Subject - And I Was Very Interested In Astronomy And In Physical Science.

I Love The John Glenn Model... I May Call Nasa In 25 Years Or So, And See If They'd Like To Send Me To Mars.
