How did we launch a spaceship from the moon back to Earth??

gravity is a bitch if you don't understand it.

You had to be there to believe it.

isn't there less gravity on the moon? wouldn't this be taken in to account when launching back to Earth? or would it make it easier?

The Apollo stayed in orbit. It's only the Lunar lander which landed on the moon.

Well.. okay that's what they say...

(Still don't know which side to choose about the moon landing hoax).

The moon has 1/6 of earth gravity, so a lot less energy is needed to launch and land there.

Orbital mechanics and gravity. it's fun stuff.

I asume the OP is a troll, since this is covered in most documentaries.

Just because I haven't researched this subject properly doesn't mean i'm a troll. I was having a conversation last night about this with someone and they were wondering too. I figure someone would know here.

The moon lacks 2 things that make space travel difficult on Earth. First is, of course, our stronger gravity. We need to overcome the force of gravity to get a ship out to space. Second, and maybe more importantly, is our atmosphere. The ship has to punch a hole through the air at around 13,000 MPH. And our atmosphere goes up a long way so you need a lot of thrust to get through it all.
The moon lacks an atmosphere so even on its surface, there is no air to have to pass through. It is a vacuum. In theory, a strong pitcher could throw a ball right off of the moon. It's gravity is so weak, only about 1/3 of Earths. And the truth is, our own gravity isn't a very strong force, it's just a CONSTANT force.

Hope this helps a little

They lowered the lander down with a large diameter
hemp rope,I think.

so therefore you would need 1/6 of the power needed to launch off the earth. but yet the Saturn 5 had 3 stages.

hmmmm

This is truly the most knowing place on the intarwebs. Try google next time

If thats the case then why when the nauts were driving the moon rovers around and kicking up the dirt from taking sharp turns as in all of the rovers videos,, why is it that that dirt/dust kicked up falls right back down exactly as it would here on earth?
If the gravilty was as its suppose to be than the dirt/dust would still be airborne right now just as yur ball

I have posted this several times and never an answer

1/6th that of earth. So they don't need all the towers, massive rockets etc...

Just as the moon lander doesn't need heat shields (no atmosphere) nor could it use parachutes (no atmosphere!).

Try reading the other posters post. something about an atmosphere. It also had to lift the weight of the fuel needed for punching through the atmosphere, and the stages them selves.

Are you really that uneducated?

Yeah to launch from earth.

But don't let something like celestial mechanics get in the way of a conspiracy.

1/6th gravity, they would fall back to the surface. and without friction from air

Post a video - lets take a look.

here ya go

So what falls fastest through a vacuum? a pound if lead, or a feather with a little parachute totalling one pound as well?

Lunar Lander

Ascent Propulsion System
(N2O4/Aerozine 50) x 1: 3,500 lbf ea 15.6 kN

Total for the Saturn V close to 9,000,000 lbf.

It does seem a big difference.

The dust DOES NOT fall like it does here on earth. only way to fake it would be to shoot it at high rate, and play it back slowly.

Well i was born raised in the country and always driving 2/wheelers/4 wheelers/swamp buggies etc and the dirt we threw up in the air fell down just as what the moon rovers are doing, actually many times the dust would go into the air and stay for hours at a time

To punch though the atmosphere the burn time is longer but to get the mass in motion in the first place would not have to worry about the atmosphere until it was moving

You do realize that the Saturn V rocket is gone by now, and the only thing that would need to take off is the ascent portion of the lunar lander, right????

You do have a point, but remeber that the lunar surface is pretty different from what we're used to, the wheels themselves on the rover was pretty wierd - made more or less from a chicken wire mesh

On the moon there is no air.

A leaf, feather, dust, hammer all fall at the same rate.

What htey hell are you trying to say?

i still wonder why if it was so easy to get the lander etc back from the moon, why have we not been going back and forth to the moon for years. It seems the space shuttle could have been shuttling bits up to orbit and launching moon missions from there. its a vacum with no atmosphere, after all.

on the same topic. how did they initiate combustion of the lander engines in the moon without o2 in the air.. was the lander really that big to carry enough o2 for both regular consumption as well as to fuel its engines through the whole trip (to and from)?

not to mention have you looked at the technology available at the time? how where they able to successfully coordinate a reattachement of the lander to the orbiting component?

not to mention. how the hell could that paper thin lander survive the amount of radiation flowing in space? or the coldness of space, if i remember correctly they didn't wear the "suits" 24/7.

and lastly. just watch the movie.. anyone who can watch that today and still belive in it obviously belives that old kung fu movies are real too, and maybe even santa.

heres a tip watch the moon landing video and speed it up a little bit. the movements from the austronauts will make more sense.

The Hows and Whys of Space Flight are covered in Elementry School Level science and even touched upon in history classes.

Things like action and reaction are covered and so to are elementry level explinations about the size and gravity of the moon and how that was used to the advantage of the appollo space missions.

Since you do not know much about space vehicles, then might I suggest a trip to your local library? There are tons of books on the subject with lots and lots of diagrams, graphs and even illutrations and pictures.

Coming here to GLP with this sort of question is going to lead to your getting bad information and will ultimately lead to fights on the subject of Hoax - No Hoax.

This last is important because folk will see your questions as trolling.
