Geno Cernan. Just got a text from my son, waking me up - had to come online to confirm, and sadly, no mistake - another hero, just..gone.
Absolutely gutted. Captain Cernan was/is one of my very favorites. Brave, insanely intelligent, and known for his candor and delightfully foul mouth, he was one of a kind. Second American to walk in space - Apollo 10, and it was a terrifying attempt; he lost thirteen pounds in the short time he was out there -- and last human to set foot on the lunar surface.

Godspeed, Captain Cernan, you will be sorely missed.
