Last week, I was at the Smithsonian Air and Space Museum.  Every time I visit, I find something very inspiring:


These are Astronaut Eugene Cernan’s spacesuit accessories.  Gene Cernan left the last human footprints on the moon in December 1972 (Apollo 17).  If you look closely, you can see the lunar dust that still coats these boots.  For a moment, there was only 6 inches of plexiglass separating me from articles that left this planet and set foot on the moon.  Wow!

I have seen that famous photo of the footprint on the moon:

Now I saw a pair of boots that made the last human footprints on the lunar surface.  This moment made me think: from now on I will use the word “impossible” with greater care.  At one time a footprint on the moon was considered impossible.  With the power of science and human ingenuity, we can make the impossible possible.
