Holy cow! Man walked on the moon fifty years ago today. What a wondrous feat.
Coincidentally I'm reading Scott Kelly's book Endurance about spending a year in the International Space Station.
His is an interesting story: jet pilot, landing on aircraft carriers, flying in the space shuttle and Russian Soyuz, and then a year on the ISS. His description of being belted into the tiny craft that shoots them off the surface of the earth is enough to trigger in me a wave of claustrophobia. A fascinating story.
