My father was an electronic draftsman. He died in prematurely in '63 while working on what I think was part or the IMU for the LEM. The company he worked for was a sub contract in that kind of thing. I was only 11 at the time and his death was contributed to long time in the pacific in ww2 so i only gather what he told me then. He also told me that they worked on the XB70. Thanks of the post

Well...not quite. The CMC didn't have the capability to calculate the burns that 'brought the mission forward'. It just had a 'return to earth' program that could calculate an abort burn. Almost all burns during a mission were calculated on the ground by the RTCC (real time computer complex) in Houston. The CMC's only job was to control those burns. The whole other stuff came into play when contact with Houston was lost and even then the CMC wasn't mandatory to get home: Houston regularly provided the astronauts with PADs (preliminary advisory data) which gave them all the information they needed to do an abort burn by themselves, in last line of defense with not just more then a stopwatch, the COAS and two stars. In the end, the CMC was a backup to a backup and backuped again by the 'stopwatch method'.

Even during WWII we had mechanical computers that could fire a shell from a moving ship and hit a target over the horizon, or fire a shell at where a bomber _would_ be once the shell reached that altitude. It's impressive, but at the same time entirely comprehensible.

Incidentally, Amy, how did NASA know where was the capsule to splashdown? The tiniest variation in trajectory at reentry would translate into significant distances, right? Was the splashdown position stablished at the start of the mission or during it? The calculations seem mindnumbing to me. EDIT: By the way, in case the wording of my question wasn't clear: I am NOT one of those imbeciles in tinfoil hats, peddling conspiracy theories about the Moon landings and whatnot. I'm honestly asking because I am in awe at the level of accuracy, planning and calculation involved.

The command module could be steered to a limited extent by rolling it during reentry. Astronaut heads towards the horizon would curve the ground track to the side. Astronaut heads towards space vs the Earth could affect distance down range. The roll orientation could be changed as required during the reentry. Despite this there were still brief time windows for maneuvers like the engine burn for leaving lunar orbit. Any delay might make it necessary for the crew to wait for the next lunar orbit and the recovery force to rush to a different location while the spacecraft was in route.

@malcolmbacchus421

Mission control had a very good idea of where the spacecraft was and its velocity from radar and radio Doppler. This allowed MCC to uplink a final state vector some 4 hours before landing. The guidance computer then did the work although the astronauts could take over using the Entry Monitor System if necessary (or even other methods if that failed). In practice the computer did it all, every time. The broad landing point was determined by where and when you arrived back and the final midcourse correction took care of that. Whilst a final course correction refined the landing point before the SM was jettisoned, the command module was itself, to some extent steerable as it had lift and its own reaction control jets. In fact, for Apollo 11 MCC added some 300miles to their original splashdown point in order to avoid bad weather. Again, all done by the little Apollo Guidance Computer.

@malcolmbacchus421

Gabriele Simionato Basically if you fire an engine retrograde, you will lower the perigee of the orbit exactly 180 degrees from where you fire it. The deorbit burn involves creating an elliptical orbit where the perigee hits the earth (that's landing), so the landing is 180 degrees from the burn. The actual landing point isn't exactly that on earth because of the atmosphere (in fact the atmosphere can make the capsule miss hitting the ground entirely, if the entry angle is wrong, by skimming off it). But very specifically, the design of the Apollo capsule, as we discussed, gave it the ability to steer slightly once in the atmosphere. Hence the statement you read.

And in addition to inertial guidance (there were redundant sets of accelerometers), and, if necessary, repeated start sighting, so long as you are in communication with Earth, you have the Doppler effect on the tracking radar and on the unified S band communications. In fact, the Doppler calculations - albeit complex enough that they could only be done by the RTCC and not the AGC - were so accurate they became the primary way of dealing with the determination. As said by others replying here, the AGC/sextant approach really became the backup not the primary method of calculating velocity and distance. The sextant and the inertial guidance system was really much more needed for ensuring the attitude of the spacecraft was correct for a burn: after all, it's pretty important when you light the engine to ensure you are pointing the right way.

Your research is always impressive.

You’re awesome, Amy!

Sorry to complicate it further Amy, but the AGC was technically the *backup* system. *ALL the trajectory computations were done by the engineers in the "trench", the front row in the MOCR.* See the _Moon Machines_ episode on the "Navigation Computer" to learn why.

To use a different sports analogy, I have always thought of traveling to the moon as being like a quarterback throwing to a receiver on a deep route. The quarterback does not throw to where the receiver is but to a point where the receiver will be at the moment when the ball gets there.

Good analogy. All while navigating through variable defensive player positions (gravity anomalies.)

Again an excellent video!

SOOOO happy to see you doing videos on Vintage Space again .. I know you probably had burnout so you are graciously gorgiven :) .. thank you again, interesting videos always ..

Please pin all the moon hoax comments so we can laugh and comment.

Better yet, I wish people who upload videos about the Apollo missions would just delete all the idiotic conspiracy theory comments. I'm so sick of seeing them on EVERY Apollo video all over KZread.

Great video and explanation! I loved the animations.

Apollo only required 2 kerbals in the vehicle to land on the moon...I mean mun.

Great video, as always. One interesting point in the launch came at T minus 15 seconds. You can hear “Guidance is internal” on the voice track. The astronauts pointed their sextant at a fixed marker on the launch pad. At T minus 15 seconds, the guidance computer set the starting spacecraft location, orientation, and velocity, using the sextant. From then on, the accelerometers and gyros were used to extrapolate the current spacecraft location, orientation, and velocity relative to that starting point. I’ve always wondered about the math, though. The earth is rotating and orbiting the sun, so what coordinate system do you use? It seems to me you want to use an inertial reference frame, which makes sense in space. But then you have to keep track of the earth’s rotation and its orbital position, along with the position and velocity of the moon. And of course the earth and moon are circling together around their common center of mass. It’s complicated.

Bill Holland Not quite. The call refers to the Guidance Reference Release (actually at T-17s give or take a bit). The AGC has little to do with this and the astronauts don't have anything to do. Up to that point the inertial guidance unit in the Saturn (not the CSM) is being torqued to keep it in line with the earth's rotation by the IU having taken its reference from the ground marker you mention. Effectively up to this point the guidance was being held to a rigid reference point. At Guidance Reference Release, the adjustment of the gimbals in the IGU is stopped and the gimbals allow to run freely maintaining their constant inertial orientation from that point (hence the word 'release'. This should have been done at the point of launch, but was done early to stop the jarring of the engine start up throwing the settings off alignment and was felt to be less risky that the small alignment error caused by stopping the updating 17s early. This was all automatic. The astronauts didn't have to do anything.

Messy stuff, ship turns on itself, highspeed, its a curvy trajectory. Dont they need special optic to see stars? Miracle the first #8 got a bullseye :)
