The Computer That Got Us to the Moon - The Apollo Guidance Computer
#TheApolloGuidanceComputer was built to navigate and guide the #Apollo astronauts to the moon. The #AGC and the inertial measurement unit (IMU) told astronauts where they were. The IMU contained gyroscopes and accelerometers. The IMU was calibrated using an onboard telescope and sextant. The AGC also controlled the engines and reaction control thrusters. The astronauts talked to the computer using verb and noun commands on DSKY (display and keyboard). The computer itself was make of core memory. The fixed memory was woven core rope memory. This is where the programs, constants, star charts, and landmark charts were woven and saved for each flight. The logic unit was make of integrated circuits (dual NOR gates). The computer could only run one job at a time. The executive determined what jobs to prioritize and run. The computer could restart programs, put them to sleep, and had very basic error checking. It was designed by MIT's Instrumentation Lab and built by Raytheon. There was one for the command service module and one for the lunar excursion module. New versions were built for every flight.
Many of the images and video came from this site. It is a great site to explore. Thanks for releasing this for the Apollo 50th Anniversary .

How do servo motors work? | Teardown and explanation beyond the pulse.

I did a teardown of a servo motor to see what it is made of and how it works. Inside the casing is the DC motor, gears, a potentiometer, and an integrated chip. I couldn't find great data sheets for the chips in my particular hobby servos. Instead, I looked up some popular RC servo chips. They all seem to have the same basic components - a potentiometer hooked to a voltage regulator and one sho...

    I don't know why this always bugs me so much, but when people talk about going to the moon and saying that the craft needs to leave the Earth's orbit, they are mistaken. At no point on any lunar mission did any craft leave the orbit of Earth. Think about it. The MOON is in Earth orbit. You don't LEAVE Earth orbit to go to the moon; you're just put on a highly elliptical orbit until you make another burn to orbit the moon. You're still orbiting the Earth though. You and your orbit around the moon are collectively in orbit around the Earth. You never leave Earth's orbit.

    • @willoughbykrenzteinburg
      @willoughbykrenzteinburg Před 10 měsíci

      @@colinsouthern This is incorrect. The TLI burn from Earth that sent them to the moon put them on a trajectory known as "free return" - - meaning if they did nothing else, they would circle around the backside of the moon and be slung around and return to Earth. At some point on the way to the moon, once various systems checks were performed, they altered this trajectory that would allow them to be captured by the moon. At no point in time where they ANYWHERE NEAR a trajectory that would escape the Earth's gravitational influence. As for the ISS, the whole "centripetal force" explanation is a gross overcomplication. It doesn't matter how strong the gravitational field you are in is. If you are in free fall, you will be/feel weightless. Many people conflate this with the absence of gravity - which it most definitely is not. The notion that you leave Earth's orbit simply because you are experiencing weightlessness is erroneous logic. You can ride a free-fall type roller coaster right here on the surface of the Earth and experience literally the same state as a spacecraft in space. It's the same weightlessness, and it is not caused by any alterations in the gravitational field, but rather the result of being in free fall WITHIN that gravitational field - - which was the case for the vast majority of the trip to and from the moon. They are simply coasting. A free fall ride here on Earth just lasts a fraction of a second as opposed to the days Apollo astronauts experience en route to and from the moon / and in orbit.

      @colinsouthern no. They far surpassed escape velocity. They aren't even orbiting the sun. They have reached escape velocity of the entire solar system. Challenge me all you want. I know what I'm talking about.

      @@colinsouthern No. STEP ONE : Launch STEP TWO : Get into Earth orbit STEP THREE : Translunar Injection - - AKA, send them to the moon. THIS trajectory was a free return. STEP FOUR : Midcourse (between Earth and moon - AFTER systems checks, etc.) taken off of a free return to a trajectory that would allow them to get into lunar orbit STEP FIVE : Get into lunar orbit. For example - the Apollo 13 explosion occurred during a point in the mission that they had already performed the maneuver that would take them OFF the free-return trajectory and on one that would allow them to perform a lunar insertion burn once arriving. They actually had to perform another burn to put the BACK onto a free-return trajectory and return. I feel like none of this is going to make sense to you.

    Great presentation! NASA has been saying for YEARS (now 2023) that they lost ALL the information on how they got to the moon. NASA says it will take YEARS to figure out how we got our astronauts to the moon and back safely traveling 25,000 miles each way thru the Van Allen Radiation Belt. Maybe you can talk with NASA to help them?!

      _NASA has been saying for YEARS (now 2023) that they lost ALL the information on how they got to the moon._ As a matter of fact, NASA said no such thing. Whoever told you that lied to you. _NASA says it will take YEARS to figure out how we got our astronauts to the moon and back safely traveling 25,000 miles each way thru the Van Allen Radiation Belt._ Again, NASA said no such thing.

      It only took the astronauts a few minutes to travel through those belts, and that radiation does not pass through a metal. The slow scan tapes were only erased on the first moon landing.
