Whould you get in this if I told you it goes to the moon?

a reply to: hellobruce

So you claim the gravity on the moon is the same as on earth....

Of course I don't.

But you would still need a lot of fuel to leave the moon.

And the fuel tanks are just not there.

I have a question.

Where are the fuel tanks?

Have you tried doing a simple internet search to see where fuel tanks are supposed to be?

here's a drawing I found on the internet showing the location of the fuel tanks (I highlighted the labels for you):

Well, that is what you are claiming....

But you would still need a lot of fuel to leave the moon.
And the fuel tanks are just not there.

So how about you work out exactly how much they would have needed, and tell us how much space that fuel would have taken up.... also tell us the weight they lifted from the moon.

To add to my post above, here is a more detailed look at the LM's propulsion system (along with fuel tank locations).

Because I cant be bothered.

I know enough to know, that it would take a very large amount of fuel to break free from the surface of the moon. And then to get into orbit. And then come back to earth.

I don't see any fuel tanks.

Do you?

So you think the lunar module took off from the moon, then came back to earth....

Do you?

Yes.

You actually have to look at them to see them!

I showed you the fuel tanks.

And the LM didn't need fuel to get back to Earth. It linked with the Command Module (CM), which then had the fuel to get back to earth. The LM didn't come back with them on the trip to Earth (except for Apollo 13, for which the LM was used by the crew as a temporary lifeboat until the damaged CM could get back to earth).

By the way, the amount fuel the CM needed to get Back to earth is not that great (at least not relatively). Once the Command Module broke the gravity of the moon, which is a small gravity well, the CM would basically "fall" back to Earth, with the Earth's gravity accelerating the craft as it fell back to Earth.

Well this house clearly needs some experienced handyman ,because they didn't learn anything from the efficient packing of the lunar module. .

But other then that this house could be lunar proof..

lets use the OP logic - at its true absurdity :



i cannot see the fuel tanks - how does it fly ?

The fuel is in the wings.

Shusshh don't tell anyone.

This plane only fly's around the world.

look how big it is and how much fuel it needs.

Here is the velocity needed to escape the Moon's gravity: 5323.9 mph
Here is the velocity needed to escape the Earth's gravity: 25,020 mph

That is a beginning point for you.
Someone else made the point of how small the payload was.

The fuel tanks for the LM descent stage are inside the descent stage.
The fuel tanks for the ascent stage are covered by a shroud on the outside of the ascent stage.

Shusshh don't tell anyone

how do you KNOW that - you cannot see them - you can only see wings

thanks for that reply - it highlights your true colours perfectly

The Boeing 747-400 can carry 624 passengers with their baggage.
That is just 622 more people than were in the LEM... not even counting the 747 crew.
Just a bit different.
Oh, and 747's don't have liquid fueled rockets on them.

I was just looking at that image on Google images I was going to post it.

Someone posted earlier. Fuel tanks, not just in a schematic.
