Last man on moon dead at 82- Gene Cernan
 

His official website: Gene Cernan | The Official Website of the Last Man on the Moon

Godspeed to the Commander of Apollo 17, and at least he did not turn the lights off when he left.

Rest in peace Captain Gene Cernan.

So sad that before long there, once again, won't be anyone alive who's walked on the moon.

RIP Gene Cernan - last man on the Moon
 

The heroes are leaving us one by one.

You are go for eternal orbit...

My hero. These men were so brave and I agree with tdracer: soon we will not have then left on Earth with us. When I was 17 years of age, I wrote to Commander Cernan, at NASA, telling him how much I admired him and all of the NASA astronauts who went to the Moon. I was stunned that I received a handwritten reply from him. He had passed my letter around to his fellow astronauts, as well as his co-workers at NASA. He was so grateful that I had written. I still have the letter.

I met Gene Cernan in 1985. A really interesting man, who gave a great talk to a group of my colleagues and our families.

I can recommend the documentary "The Last Man on the Moon" on Netflix:

That is so sad. Only last few days I found out about his recent documentary 'Last man on the moon' and I was trying to get a copy when I read this. Saw him in the other documentary I have, 'In the shadow of the moon', and I always thought he was the coolest of the lot. Real sad news. We have now lost the first and the last man to walk on the moon.

Spot on, Randall

Meta-Text for this sobering cartoon:

"The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision."

Marian,

Did you make up the meta text or is it on the xkcd site?

Number of living humans who have walked on another world
 

Given that "other worlds" is generally understood to mean other planets, it's a fairly easy graph to draw ...

I42, the metatext as copied of the site:

"Given that "other worlds" is generally understood to mean other planets..."

For long-term habitation, I guess moons are subject to much greater extremes of temperature than planets, so a moon replica of mother-Earth is out of the question. But does that disqualify them as "worlds", Dave? Rumour has it that several moons of Jupiter and Saturn are a lot less uninhabitable than their gas-giant planets.
