#CarlSagan was a hero of mine
In the 70s I lived on a large commune in the hills near NASA Ames. One of us worked there under Dr Sagan making a stereo map of Mars from Mariner 9 photos

Never one to turn down an audience he brought his slideshow (the bones of Cosmos) up the mountain and gave 150 hippies a tour of the Universe projected on a pair of white sheets!

It was truly awesome ✨ 🚀🪐
