Progress At NASA Over The Past 45 Years

Forty-five years ago NASA could send people to the moon. They can’t do that any more, but they can generate fraudulent climate data much faster than previous generations could have ever dreamed of.

    NASA successfully hid the Sun – the Creator, Destroyer and Sustainer of every atom, life and world in the solar system – from the public during the entire space age.

    NASA propaganda was reality turned backwards:

    The natural process that generates and discards hydrogen from pulsars became an imaginary one that captures and burns interstellar hydrogen to produce pulsars.

    NASA never built that. It was all done in Hollywood, or so I’ve heard.

      NASA went to the Moon in 1969 and returned with samples of lunar soils that showed atoms at the top of the photosphere and in the solar wind have undergone nine-stages of mass-dependent fractionation that each enrich the abundances of light-weight atoms like hydrogen relative to those of heavier-weight atoms like iron.

    I’m currently reading “Moon Shot”, the book by Alan Shepard and Deke Slayton that recounts the inside history of the USA space program through Mercury, Gemini, and Apollo stages.

    Chapter One begins with details of the Neil Armstrong-Buzz Aldrin landing. Armstrong had to do quite a bit of maneuvering because they were coming down in a field of large boulders. After passing sideways for several kilometers, they touched down safely – with 16 seconds of fuel remaining.

    That’s why Houston said “You’ve got a bunch of guys about to turn blue”.

    There were numerous other near-misses in the early space program.

    I recommend the book highly

      Carrying the Fire by Micheal Collins would be a great book to follow up on that one.

      As you listen to the radio commo you here warnings being given. Those are computer overload warnings. The computing power carried on the LM was much less than what is found in a modern smart phone today. So it just couldn’t handle the volume and had to prioritize it’s tasks.

      The skin on that lander was so thin that it noticeably bulged when pressurized. On earth if a worker dropped a screwdriver very far it could and punch through and that actually happened once. Those guys, all of them, had some huge stones.

      I feel so fortunate to have lived at a time when the space race, from Sputnik to the moon missions were going on. As a kid I watched very thing I could about it.

        Informed word has it that a certain time-consuming ‘task’ should have not been running on the LEM computer at that time; a particular line on a human-read checklist was overlooked and an item was not switch-selected to be off …

        Nowadays there is a lot of material on the web on the computers used by NASA on those missions, including some code listings. A number of individuals have even constructed replicas (this is aside from ’emulators’ running on a PC) using more commonly TTL logic vs that available in the (probably something like RTL).

        From the Galaxiki Community Blog:

        “Build Your Own NASA Apollo Landing Computer (no kidding)”
        January 30, 2008

        If you’ve ever programmed ‘down on the hardware’ via assembly language like on a Z80 one begins to realize that quite a bit can be accomplished if one does not have to ‘paint’ or move a bunch of pixels (via BitBlt) around when operating with a 4 MHz clock yielding between 1 MIP to 1/4 MIP depending on the instruction being executed. Realizing you have around half a million ‘instructions’ you can execute each second is a BIG step up from having a human being (or even several human beings!) trying to do the same thing! Full disclosure: One time Z80 assembly lang prgmr here …

        Shazaam! A video of the little beast!

    “hear” not here darn it.

    Maybe of some general interest:

    “DR. Widnall on Apollo’s guidance, navigation, and control”

    (Dec 10, 2008) Dr. William Widnall speaks to Aero-Astro students about heading the MIT/Draper team in the ’60s that developed Apollo’s guidance, navigation, and control system.

    (Caution: Dry, technical material only a space junky, aerospace engineer or ‘techy’ might enjoy)

    Another off-the-beaten-trail video; the making of the Apollo Guidance Computer courtesy of the Draper Instrumentation Lab at MIT and Raytheon in Waltham Mass.:

    “A mid 60s American documentary illustrating the design, build and use of the Apollo Guidance Computer.”

    In the MIT Draper Lab portion of the video it is demonstrated how the AGC was used via “Nouns and Verbs” entered via the “DSKY” (Display and Key assembly) and then a manager at Raytheon shows how the modules within the computer were manufactured and tested; surprising how much automation was in use via punched paper tape and punched cards even to perform the wiring!
