Ok, I know you’ve been perplexed for a week. You’ve been patiently waiting for me to read my bathroom scale on top of my 210 mile high mountain that apparently even the U.S. Geological Survey knows nothing about (I checked at their web site.) Wait! You say you have no clue what I’m talking about?? Hey, you’ve got to read Weekly Challege 4 FIRST! None of this lazy stuff going right to the answer.


Go read Weekly Challenge 4, think about it for a while, and come back. I’ll wait right here for you.


And now the answer—

As I write, NASA engineers at Kennedy Space Center are working mightily on space shuttle Endeavour to repair a hydrogen leak that scrubbed the June 13, then June 17 launches. Endeavour is headed for the International Space Station. NASA reports that the next flight opportunity is July 11—WHICH MEANS I’ve got plenty of time to get ready for my way cool experiment.


I’ve heard a lot about weightlessness, and astronauts having a great time floating around. The shuttle flies at an altitude of 210 miles (340 km) when rendezvousing with Space Station. (For a cool take on this read my earlier post The Business Trip.) So I wanted to find out first hand what’s going on up there. Since they don’t have a spare seat, I looked far and wide to find an amazingly tall mountain whose peak rises to the shuttle’s orbital altitude. See my mountain in the picture? Mt. Everest is only 5.5 miles (8.8 km) high. MY mountain is 210 miles (340 km) high. It took me some time but I finally found it south of the Land of Make-Believe, down a not too well traveled path. Still, you’d think someone would have noticed it.

This post is a Teachable Moment in the News.

This is crossposted at the Huffington Post HERE.


We came in peace for all mankind

It was a moment that changed us. A moment that began a new chapter in the book of the human race. It was an achievement shared by all the peoples of the world … and in that moment—our differences were overwhelmed by the common bond of our humanity. And hear ye future generations—it was a testament to what we are collectively capable of achieving when we aim beyond the horizon.


Many of you reading this lived through it and were powerfully moved. Many of you were not yet born—but yearn to know what it was like.


I created this special post as a place where those that lived it could share the experience with those that did not.


If you were moved 40 years ago next month, please leave a comment below. Think about where you were, what it meant to you, and what it meant to the world. And we warmly invite you to put your thoughts to ‘paper’ here.


I’ll start it off with my own very personal experience in the recent post: The Launch of Lunar Reconnaissance Orbiter Brought Back Memories of Apollo 11.


I have also assembled a list of resources below to help you celebrate with friends and family, and follow the flight—in real time—as it happened 40 years ago. I’ll be adding more to the list every few days.


With best wishes for great memories and wonderful sharing time,

Jeff Goldstein, Center Director, NCESSE
