This is the part i don`t get so i will make short verbiage of it.
I understand the enormous Saturn V rocket and mass fuel payload used to get out of earths gravity to outer space and all the complex math used to have it running a straight bee line for the moon once up in space given the earths rotational speed etc......etc...
Sorta point and shoot if you will at the right time.
The service module is orbiting the Moon, the LEM lets go and does a controlled decent to the Moons surface and burns off it`s first tank of hydrazine with ten seconds left to spare. and not landing exactly where planned, but they make it,....touch down.
Who`s doing all the new math in relation to where they don`t know exactly where they are at now sitting still on the moons surface and the Service module making an orbit every 25 minutes or thousands of miles per hour.
Now it`s time for lift off to break the Moons lesser gravity burning mass fuel to meet the orbiting service module going how many thousand miles per hour.
Are they going to crash head on, overshoot their trajectory, come from behind and miss it altogether without enough fuel to catch it because it`s speed is moving at constant velocity or even find the service module at all , way up there ? being no bigger in diameter than my own driveway trying to link up to a Metro sized bus?
Even with the 1969 computer and possible radar system ???
Like threading a needle from a mile away. Time....time becomes very fluid and difficult to handle in such a tight trigonometric calculation especially when there are no known controlled reference points to calculate the math off of or launch timing from the moons surface..
How they going to be able to link up, get into the same plane of orbit and have all this extra fuel on board the LEM to catch up and dock up with the Service Module? when they barley had enough to drop out of space and do a controlled decent.
Put it all together and the little amount of fuel the LEM carried on board in its second tank to do all this work with plenty left over ?
OH! Yea, who did the spacewalk and go out to the leg of the LEM after it was docked onto the service module and retrieve the film out of the camera?
You know the film roll that didn`t get damaged or melted from hydrazine burn nozzle, those low angle pictures with the leg mounted camera that recorded mankind's first step onto the moon without anyone else there taking the picture or moon dust on the lens?
If i remember that first prototype picture of the testing LEM on the earths surface, weren`t the leg footprints much further apart than the actual LEM`s to avoid the heat of the rockets main thrust nozzle?
Not sure how that leg mounted Hasslblad took all that close proximity heat and survived?
The LEM got dumped in space before coming home, so someone had to do a spacewalk to get the film or even if it was some kind of link video camera, did they have a small tv station on board? And again with the moon dust on the lens? What did they have? A remote controlled dust proof pop off lens cover to record the event? All mystifying.......chain of perfect events.....
I would love some input on this??
I`m no physicist or mathematician but i did manage a couple years college, at least enough to understand that triangulation and speed are a difficult thing to calculate when objects are moving.
