    Re: Apollo 11 - 50 years on.

    It always interests me how we've gone from a comm style that was very military-rooted to what we have now. What do I mean?

    1. If you say "Roger" these days, you're saying, "I heard you say something but I didn't understand it." If you "Roger" me, I'm going to repeat myself or change my wording. The preferred nomenclature, Dude, is "copy".

    2. We do not use "over" ever, but that's probably because we have better communications equipment these days and have the Quindar to let us know that you've initiated or ended comm (typically with a handset with a big old trigger).

    If you "Shirley" me, I'll know you're serious and tell you to never call me Shirley again.

    3. My wife is finally used to me replying "copy". I have told a waiter "that's a good copy" more than once when they get my order right the first time. I always get a weird look.

    4. The hardest thing that I see with this comm is not having video. We so often have video with the crew and can get non-verbal cues (thumbs-up always helps) that I can't imagine using our crappy words to ask about amazing things that a crew sees. We're going to have to break ourselves of that crutch if/when we go to Mars...

      I imagine the shift from the Apollo era, where the Astronauts were almost exclusively military test pilots, to the Space Shuttle era, which involved hiring plenty of non-military, specialist astronauts, probably has to do with the changes.

We manage the NASA science on ISS and make sure that they have the resources (power, cooling, data, commanding links, video, crew access) on an everyday basis. I'm currently serving as the Assistant Payload Operations Manager, which mainly means that I'm stressing out, getting fatter on the candy in the office, and pulling my hair out (literally) trying to take care of three astronauts [until tomorrow, when it's six], keeping them healthy and motivated to do good work to serve our science and engineering clients. It's fascinating, frustrating, and rewarding.

        Before this, I wrangled facility racks around here for a contractor; before that, I built hardware that sits outside on station, keeping big pieces of replaceable equipment in an appropriate temperature range and keeping them from floating away. Before that, I helped develop a science payload. Next month, I hit 20 years in aerospace. I came to UAH because I wanted to work in this community — along the way, I fell in love with a (now-crappy) hockey team.

        Apollo XI is important, but I hate that I missed it.

          I found this on YouTube the other day. Apollo 11 descent to the moon. First few minutes explains the whole procedure, the rest is audio and video.

          Enjoy. https://youtu.be/xc1SzgGhMKc

            Getting close now; around 6 hours to go.

            I've found pairing Mission Control with Sonic Youth works out extremely well.

                Re: Apollo 11 - 50 years on.

                We are just 2 hours from the Lunar Module Eagle undocking from the Command/Service Module Columbia.

                After undocking the craft separate, then the Lunar Module begins its decent.



                From this source:

                During the spacecraft’s second pass around the moon, Mission Commander Armstrong and Lunar Module Pilot Aldrin moved from the CSM into the snug confines of the LM to prepare for detachment, leaving Command Module Pilot Michael Collins to anxiously wait and circle in orbit.

                Next came the “powered descent” of the LM, what Neufeld calls “the most critical and dangerous part of the flight.” After separating from the CSM, Armstrong and Aldrin piloted the 32,000-pound LM for two hours toward the lunar surface. At the last minute, with fuel supplies running dangerously low, Armstrong realized that the computer’s auto-landing program was dropping them in the middle of a boulder-strewn crater.

                “In what’s become a famous moment,” says Neufeld, “Armstrong took over manual control and began maneuvering the spacecraft forward faster so it would skate over the crater to a clear spot beyond it.”

                  For programmers out there, this site has the Apollo Guidance Computer code libraries and a simulation environment. You can run your own Apollo missions.

                  Humans are amazing. I hope the criminally insane 33% don't kill us all before we find FTL and leave them behind.

                    Some jokes/sarcasm from our duo as they circle the moon in the LM before they start their descent:

                    101:50:16 Armstrong And, one thing I'd appreciate if you could – see if you could - find the -
                    101:50:30 Aldrin What?

                    101:50:36 Aldrin Yes. Which one do you want? I've got - -

                    101:50:40 Aldrin That it? Where do you want it?
                    101:50:52 Aldrin Trade you that for a piece of gum. There it is.
                    101:50:59 Armstrong ...

                      102:09:38 Aldrin No, not yet - wait until the light goes out. Did that thing want to - Hey, I didn't know that could do that. You don't hear that, huh? (Laughter)
                      102:10:01 Aldrin Hear that, too, huh?
                      102:10:05 Armstrong Sounds like wind whipping around the trees.

                      Interesting to listen to the feed, you can hear a wind whistling/buffeting sound in the audio from the LM.

                            I have the CBS News YouTube stream on my TV, and Oh. My. God. They were using toys, models, and real life sized props to illustrate what's going on. It's so late 60's it hurts.

                            Also, it's interesting the live stream mission control audio on the CBS News YouTube feed is ~7 seconds behind the Apollo in Real Time website.
