"In this scientific American sixty seconds science I'm Christine Herman July Twentieth Marks Fifty Years Since human human beings I landed on the moon that momentous day in Nineteen sixty-nine made astronauts Neil Armstrong and Buzz Aldrin household names but years before that a lesser known figure was on a mission to make that first moon landing possible. His name was John Kobylt. The son of Dutch immigrants cobalt grew up on a farm in Joliet Illinois. He studied engineering at the University of Illinois and eventually worked his way to NASA it was there in the early sixties that he put his career on the line to champion champion what was at the time an unpopular idea but would ultimately be critical to getting Apollo Eleven to the moon and safely back. John faced a mixture of indifference at times abuse and at times ridicule that he never forgot. Not until things started to change and engineers started to realize his data might be right todd's Willik author of the new audible original spoken word book about Holtz Life. It's called the man who knew the way to the moon so what was whole bolts unpopular idea. He championed what's called Lunar Orbit Rendezvous. The concept involves sending a spacecraft into orbit around the moon and from there sending only a small lightweight craft down to the moon's surface instead of the entire ship is will excess. Says while Holt didn't invent the idea he was the one who started to apply it to the technologies that were within Nastase grasp at the time most of the people who know the most about this mission feel that without lunar orbit rendezvous Apollo couldn't have succeeded exceeded and without John Kobylt you probably wouldn't have had lunar orbit rendezvous will expose also explores the kinds of challenges NASA engineers face today as they make plans to get back to the moon and ultimately to Mars when you talk about Mars Gosh one one hundred fifty million miles orders of magnitude of a bigger problem. Do we do some form of Martian orbit rendezvous. Do we send a station build a station in Martian orbit that we can stage down to the surface to manage all that mass a lot of problems."
