They had satellite communications in the '60s.Given this is 1960's technology - land lines,
They had software in the '60s.no software,
That's because the computers were in another room. You do understand the difference between the monitor on a laptop and the CPU, right?and all the banks of screens you see in 'Houston' are tv monitors, NOT computers,
Right?
Everything was done according to a carefully planned mission profile. You think that a "real" mission would have just winged it?everything was done to a pre-prepared script.
If you'd watched that video I posted about Lunar Orbit Rendezvous you'd have known how they did exactly that. But you don't actually want to learn anything, just assert that you are here to generously share your brilliance with others. The above actually reminds me of a time when a flat earther said, "If the earth really orbited the sun, we'd see different constellations in the sky every six months".Precision was absolutely key. For example, in docking and undocking. Think about it, Collins orbiting the Moon whilst the guys were 'collecting rocks' needed to be in exactly the right place at the right time for when the capsule took off from the Moon, etc.
Jesus Christ! You're arguments are just getting dumber and dumber.So, ditto, the "live" tv broadcast. Had there been a satellite geopositioned (=at the same speed of orbit as the Moon so that in effect, it is stationary to it, per position) nil problemo. But it had to ensure a localised satellite was ready in place at the right time - how incredibly logistically efficient would one need to be to have it there just when you need it?
Communications satellites, geostationary or otherwise, are used to relay transmissions between transmitters and receivers that are not in line of sight with each other. Like, if you're in London, and you want to broadcast a TV signal to New York, you can send the signal to a transmitter that sends it to a comm satellite, which amplifies it and sends it back to earth. An antenna in or near New York can then receive the signal from the cam satellite and send it to a TV transmitter there.
But, if you physically lift London out of the ground and put it in the sky above New York, you don't need the satellite. Communications satellites are like a mirror that lets two people wave at one another around the corner of a wall. If the two people are standing in the open and can directly see one another, they don't need the mirror.
The spacecraft and the DSTN antennas were in direct line of sight when they communicated. Do you understand that?
Vixen, you aren't thinking at all. A landline is just a wire. If you're staffing a radio telescope receiving a transmission from space and you plug a set of headphones into a jack to listen to it, that's a wire, too. You can route the signal to another wire that can travel through land lines to anyone where that network reaches, including the White House.And then Richard "Tricky Dicky" Nixon ringing Apollo by landline and chatting to the astronauts in person...yes, radio technology was absolutely marvellous: signals bouncing from one station to another to make this possible... Yes, mate! It's possible if we all just think hard enough.
At this rate you're going to ask how the Apollo crews were able to take photographs without their souls being stolen.
