Alan Bean, 4th Person to Walk on the Moon, Dies at 86
Just looking at the Wikipedia category, there are 12 people who have ever walked on the moon: https://en.wikipedia.org/wiki/Category:People_who_have_walke...It looks like we have 4 left:Buzz Aldrin, age 88: https://en.wikipedia.org/wiki/Category:People_who_have_walke...David Scott, age 85: https://en.wikipedia.org/wiki/David_ScottHarrison Schmitt, age 82: https://en.wikipedia.org/wiki/Harrison_SchmittCharles Duke, age 82: https://en.wikipedia.org/wiki/Charles_DukeIt will be a sad day for me when there's nobody left who has walked on our nearest neighbor. It feels like a turning away from possibility.
