So did NASA rush things and risk the lives of US astronauts JUST so they could have bragging rights??
That shows NASA in a very bad light if true..
I've read a little about the changed mission for apollo 8..
Sad that ego trumps safety...

Does it ever bother you that you have a difficult time telling a film that was produced for "infotainment" purposes apart from reality? Sad, really.

You are saying the rocket engines are still active?

Speaking of the white debris, what is that very bright white object
in the middle of the screen that is brighter than the clouds?
(I think I know what you are going to say)

And why is the insulation flammable, what is it made from?
Also, the flame that shoots out from the tube is coming towards the rocket.
How is that possible? Shouldn't it be moving away from it?

And if the engines are still active, why do the stages break away so slow and methodically?
I dont see a increase in speed. They just seem to break away on their own and float down not
being influenced by the rocket engines.

Regarding the photography.
Why didnt it get damaged during reentry?
They were activated by computer, as part of the separation sequence. As you can see they run out and get ejected, they only had about 40 seconds (in real time) of film in them.

I still would like to know how much film was in the camera(s) and who activated it to turn on.
It's for illustrative purposes. There were no such cameras on any of the manned missions. The separations would have looked pretty much the same.

Why would NASA attribute those sequences to the other Apollo missions?

watch this video of Apollo 8
FoosM, Apollo 8 is my favorite!!
Frank said "8,000 miles" which equals 12874km. Wiki says "The inner Van Allen Belt extends from an altitude of 100–10,000 km [7] (0.01 to 1.5 Earth radii) above the Earth's surface, and contains high concentrations of energetic protons with energies exceeding 100 MeV and electrons in the range of hundreds of keV, trapped by the strong (relative to the outer belts) magnetic fields in the region."
And the outer belts, says Wiki, "The large outer radiation belt extends from an altitude of about three to ten Earth radii (RE) or 13,000 to 19,000 kilometres above the Earth's surface. Its greatest intensity is usually around 4–5 RE."
And Earth radii is according to Wiki, "Distances from points on the surface to the center range from 6,353 km to 6,384 km (≈3,947–3,968 mi)."
According to Frank Borman's recollection in this video, the originally planned 3rd Apollo mission would have been long duration, orbiting in space, approximently 13km apogee, somewhere inside the 2-3km gap between the inner and outer VAB's.
Who planned that mission, Walt Disney?edit on 1/13/2011 by SayonaraJupiter because: facts and figures
The ionosphere is a portion of the upper atmosphere, between the thermosphere and the exosphere, distinguished because it is ionized by solar radiation.
The South Atlantic Anomaly is a phenomena that takes place in the ionosphere, at the magnetic equator, where the Van Allen radiation belt is closest to Earth
If the size of the belts are close to a third of the way to the moon.
And it took Apollo 3 days to get to the moon... how could the spaceship
go passed the belts in a couple hours?

Hi Aftermath...
Do you think its possible NASA faked some of the Lunar photos?

Distances are all to scale. Times indicate the difference in time from the previous mark.
And what about the return trip?
Second --- Earth's acceleration due to gravity is higher than the Moon's.
Nope, it wasn't perfectly straight, which is why I said it was a rough estimate. But given that only covers about a fifth of the total distance covered, it's not a horrible example.

Ive seen such simplified explanation before.
In reality the Apollo craft did not go a straight line did they?
Originally posted by FoosM
Secondly, you, or NASA, are basically saying that the Apollo missions managed to cover
a third of the distance to the moon in less than half a day?

How fast were they going and what part of the belts did they traverse?
Earth's gravity ALWAYS has an effect. Acceleration due to gravity at the surface of the earth is 9.8 m/s^2. At the distance of the moon, the acceleration due to gravity from the earth is 0.00027 m/s^2. Small, but still there. The acceleration varies by the square of the distance. Cut the distance in half, and the acceleration increases by 4 times.

At what distance would Earth's gravity have an effect and to what extent?
Another 52 minutes and they're going 39,743 km/h and are at an altitude of 191 km. That's their maximum speed and that's when the reentry starts.
While space junk is a problem, it's not as bad as people think. I believe there's about 500,000 bits of "junk" bigger than 1cm in size. But lets assume they're all at an altitude of 350 km. The sphere that encompasses the earth at an altitude of 350 km above the surface has an area of 567,646,095 square kilometers. So that means each bit of junk has, on average, 1,135 square kilometers around it. That's a radial distance of almost 40 kilometers between each bit. Now take into account they're not all at the same altitude. So the volume of the space, and the average spacing, goes up from there.

That would be very difficult to plan today with all the junk that's up there..
Hitting a small piece of debris at almost 40,000 kmh would not be pretty.
