Buzz Aldrin did an IAMA on Reddit the other day and I thought it was a great read. He's inspiring, and well spoken for an 84 year old. I'm sure it's been plastered all over, but thought it was worth posting in case anyone missed it.

A harrowing description of the moon:

Buzz Aldrin wrote:

My first words of my impression of being on the surface of the Moon that just came to my mind was "Magnificent desolation." The magnificence of human beings, humanity, Planet Earth, maturing the technologies, imagination and courage to expand our capabilities beyond the next ocean, to dream about being on the Moon, and then taking advantage of increases in technology and carrying out that dream - achieving that is magnificent testimony to humanity. But it is also desolate - there is no place on earth as desolate as what I was viewing in those first moments on the Lunar Surface.

Because I realized what I was looking at, towards the horizon and in every direction, had not changed in hundreds, thousands of years. Beyond me I could see the moon curving away - no atmosphere, black sky. Cold. Colder than anyone could experience on Earth when the sun is up- but when the sun is up for 14 days, it gets very, very hot. No sign of life whatsoever.

That is desolate. More desolate than any place on Earth.


What he though when he was on the moon:

Buzz Aldrin wrote:

"Where are the billions and billions and billions of people, on what I'm looking at? We're the only 3 that are not back there."

And we didn't get to celebrate. Because we were out of town.


Such a jokester:

Buzz Aldrin wrote:

When Mission Control said, to us, as we were about to leave "Tranquility bass, you are cleared for liftoff," I responded by saying to them "Roger, Houston, we are number one on the runway."


On the movie Gravity:

Buzz Aldrin wrote:

I thought that the movie Gravity, the depiction of people moving around in zero gravity, was really the best I have seen. The free-falling, the actions that took place between two people, were very, I think, exaggerated, but probably bent the laws of physics. But to a person who's been in space, we would cringe looking at something that we hoped would NEVER, EVER Happen. It's very thrilling for the person who's never been there, because it portrays the hazards, the dangers that could come about if things begin to go wrong, and I think that as I came out of that movie, I said to myself and others, "Sandra Bullock deserves an Oscar."


There's a bunch more replies to questions in the IAMA, but those were the

That was pretty cool, thanks for posting it!

That also reminds me, has anyone actually watched more of/finished Cosmos? I think I'm still only about 5 episodes in

Interesting AMA by a NASA team on Reddit:

We're the team that designed and built Orion, NASA's next generation spacecraft. Ask us anything.

To get you interested:

We have been continuously living and working in deep space for over 30 years, but we are just now figuring out how to go beyond LEO to deep space. Orion is the vehicle that will pioneer deep space.


And here's a bonus video of astronauts doing some semi-cool shit:

I realise i'm replying to a 4 month old question, but i did eventually finish COSMOS.

It was painfully preachy.

Hmm that's a comment more for the actual thread about COSMOS instead of this thread but instead of changing my mind and moving it there i'm just going to go ahead and post here anyway because who is there to stop me.

Fucking amazing.

Ever seen Saturn through a telescope? Mind blowing.

James Webb should be fantastic, only a few years away too!
