Hi guys,

What do you recommend reading? I'm hoping for something from the perspective of one of the astronauts that landed on the moon but I'm open to anything.

Thanks in advance! :)

Hello I am curious if someone could help point me to documentation about the 344 single points of failure. I find it fascinating. I've seen This risk doc or others mention "M. Menzel, JWST Single Point Failures, Status and Mitigation, JWST-MEMO-033490, 2017". I haven't had much luck in finding that specific memo.

I am interested about the complexity and would love to read a risk assessment or technical documentation to learn more.

This itch was started after watching the netflix documentary "unknown: cosmic time machine"

asking for a friend

Through my work I was very unexpectedly fortunate to be led into meeting Mr. Loden and being allowed into his home. My mind was, and still is, blown by my real-time face-slap of a realization during what I thought was just going to be a normal day.

At first, I just thought that he and his wife were very nice, older folk and I enjoyed working with them over the few months that we interacted. His name rang a familiar, but very quiet, chord in my mind that sounded every time I came across his name in my files but I didn’t put too much effort into thinking on it and went about my life as usual. For me, he wasn’t ‘The’ Hal Loden, yet. It never crossed my mind.

On the final day that I would be working with them, we arrive at his house. He comes out to greet us with a smile and a hand shake, asks us how our day has been and leads us into his home. On entering, we passed a small collection of what looked like a few letters, photos and some colorful trinkets. I paid little attention as we were there in a professional manner and had a task to complete. As we worked we talked of pleasantries, his children and grandchildren, a few things about his home that he was proud of and enjoyed, the great weather we were getting and we spoke a bit about Golf. Not once did he mention his past work. We just talked about regular, ‘ol, daily life stuff. It was good chit-chat.

On one of my final walks through his entry hall, I stopped for a moment to take a better look at what was hung on the wall. Once I realized what I was looking at, I have to admit that I lost some composure. On this small patch of wall hung Letters from Presidents, NASA Commendations and MULTIPLE APOLLO MISSION PATCHES. Flight Control is a GO for Launch! It all clicked, all at once. All the film, books, essays and articles that I had absorbed came rushing back. I guess I was visibly shaking because when I looked back over my shoulder at Mr. Loden standing in his living room, he shot me a smooth, little smile and then went back to speaking with my colleague. He knew that I now knew who he was.

I got outside and had a complete freak-out. This man, a Hal Loden, along with many important others, shares responsibility for some of the greatest accomplishments that any Human Beings have ever attempted. And I’m in his home! Talking about Golf and his family! I shook his hand and he greeted me like a friend! I get goosebumps every time I think of it.

As we finished up and were heading out, I tried my best to not embarrass him or myself. I must have been smiling like a huge dork when I shook his hand goodbye because he smiled in recognition of my realization and excitement. He told us to have a nice rest of our day and waved us off.

I didn’t expect to find one of the people that helped excel our species into the greatest accomplishments that any Human can boast, living quietly, just a few minutes up the road. One of the coolest experiences I’ve had. 10/10 recommend meeting Mr. Loden. He and his wife are very nice people.

For example, aircraft flight time is logged either from engines on/off or wheels off to wheels on the ground. How is EVA time logged? Something like airlock door open to airlock door closed?

MIL gave this to us, she thinks it's fro. 70s or 80s. Any ideas on which shuttle this might be? TIA
