General Discussion / Re: Apollo 11 video feed delay?

« Last post by Allan F on March 23, 2024, 11:07:11 PM »

As the SSTV feed was routed to a monitor, and from there picked up by a TV camera and retransmitted across the world, it was practically instantaneus.

I'm a bit confused. The 16mm footage you refer is not transmitted live, it is film that was processed after the mission concluded. The rest of the transmissions were "live" with roughly a 2 second delay. The only delayed video from was from A17 when the Cernan was driving to the parking place the antenna was positioned properly to have the DSN pick up that signal. A11 video was processed to a format that could be presented to the TVs around the world. I don't remember if there was an additional delay other than the transmission delay. That may be addresses in Jay's Clavius site.

RIP Gen. Stafford. Another Moon astronaut passes away.

Also, he thinks the CSM is also inside the 3rd stage.

The confusion stems from your inclusion of the SLA into the 3rd stage. It was a separate entity.

Are your numbers for the third stage or for the third stage AND the SLA?

I used a cylinder calculator and came up with 22,781 cubic feet.

Correct.

Now we look at the list. There were 2 fuel tanks the larger held almost 80,000 gallons the other just over 6,000. The fuel alone takes up 11,417.52 Cubic feet of space.

His figures are fairly off, but his volume is similar to what I calculated.

That's not counting the tanks to hold the fuel or the lines and pumps to move it.

Er, what? Once you put the fuel in, there's no room left for the fuel?

Quote

Remember it's already more than ½ full even if you just literally poured the fuel in the rocket.

Um, yes, that's how it works. A bit over half the volume of the stage is taken up by fuel. That leaves a bit less than half the volume for lines and pumps and engines and stuff.

Morning / Afternoon All.

Another Facebook group argument / debate. Below is a comment from somebody. Is there a website which literally adds up the bits within the Third stage that shows it does all fit

Phase 3 of the Saturn 5 rocket is 61.6 feet tall and 21.7 feet in diameter. If it was a cylinder (which it's not the top has a lander attached to it and it's much smaller and the diameter slowly decreases at the top)

And that's if the entire rocket was shaped like a cylinder, again it's not

We still need room for Insulation so now your available space is even smaller.

Next subtract the cubic feet needed for the rocket's engines.

Don't forget the Lander itself.
We still need an oxygen supply, batteries, computers, and room for 3 Astronauts. It literally doesn't all fit.

cheers guys
