There is a young man renting a room in the house I live in,
That doesn't believe we went to the moon, Let alone walked on it.
Obviously we did walk on the moon.
My question is this:
What do I say to him to convince him that we did?

There is no concrete proof that we did or didnt.
Is he a fundamentalist mormon? Because they don't believe the moon thing.
BTW, I can't believe I just admitted that on Gather. LOL
It messes with my logic sensors. They tingle every time this comes up.
How much jet fuel does it take to launch off the moon? Less than earth, but still a lot, right? How do you set up the proper trajectory without a launch pad? Why wasn't there a delay in their talks to Houston? There's a delay when Matt Lauer in NYC talks to Houston today with all the advances we've seen in communications.
Seriously, tingling logic sensors on this one.
Maybe it happened. Maybe our govt. pulled the wool over your eyes. I know that's hard to believe, our govt. would never fudge something important.
Of course I wasn't born at that time, so that would obviously play a roll in my logic sensors tingling.
You know better but it isn't worth the trouble to convince him.
He just thinks that government is completely untrustworthy, especiall over the most important things.
logic will answer all DUH

Jamie C. asked a few cool questions...
How much jet fuel does it take to launch off the moon? Less than earth, but still a lot, right?
A lot less because not only does the moon exert only 1/6 the gravity, but also the LEM (Lunar Module) was a relatively tiny vehicle with paper-thin foil walls, weighing only 10,024 lb on takeoff. So the LEM needed less than one percent of the thrust required for the takeoff from earth.
How do you set up the proper trajectory without a launch pad?
You do it with thrusters, little rockets mounted on the side of the vehicle that are able to change the yaw, pitch, and roll of the vehicle.
Why wasn't there a delay in their talks to Houston? There's a delay when Matt Lauer in NYC talks to Houston today with all the advances we've seen in communications.
There was a delay. For Matt Lauer, it's a 46,000-mile round trip to a communication satellite in stationary earth orbit at an altitude of 23,000 miles. Plus some additional delay through all the cable and circuitry on the ground. If he's talking to someone, double that distance while he waits for the answer to return. That's only about a half-second "in the air"--but a further pregnant pause is added as the signal is processed and eventually stuck into Matt's ear. Earth-to-moon is about 6 times as far as a single "bounce," so the lunar round trip "in the air" is only about 3 seconds, plus processing delays on the ground.
Now, I figure people went to the moon, but Nasa did some goofy stuff with the photos, for whatever reasons, and that has not been addressed by them. Until they explain why that happened, I can't really blame those who dismiss the whole thing as a sham, and can't say with absolute certainty it wasn't. That is very unfortunate, cause it was clearly a great accomplishment, I think.
So, I'm still on the fence with the 5% of Americans who just don't know what to believe. Both sides give compelling arguments.

The guidance systems aren't really computationally difficult to implement (a good thing, since the PC hadn't been invented yet). But you have to carry enough fuel to get there and back, and everything has to be the right size and so forth. I think if you're careful you'll find that it checks out just fine. Healthy skepticism will be your friend throughout!
I didn't even know there was a program. I looked at the photos.
In addition, distant objects don't fade away into an atmospheric haze. In photos, distant ridges and mountains look like nearby hills. That helps explain why you can view a photo of a distant landscape with the LEM in the foreground, and a different photo of apparently the same landscape with no LEM in the foreground.
It would be an interesting study to take a look at a map of Tranquility Base and the surrounding topography to get a better idea of the sightlines and distances to the geographic features that show up in those photos. I haven't investigated that, but it wouldn't be difficult.
As far as the mounted camera or cameras in general, you ought be be able to find quite a bit of information about that by Googling it. I know I did. I don't know what the deal was with your friend.

Quote from the site:
Westinghouse Apollo Lunar Television Camera - Used on the lunar surface on Apollo 11 only... Few people who lived during the time of Apollo will ever forget where they were when they watched Neil A. Armstrong make his "One small step" into the history books on July 20, 1969. The fuzzy, gray images beamed back from the lunar surface for 2 hours that night allowed all of us to share in the wonder of that historic event. The machine that was used to do this was named simply the Apollo Lunar Televsion Camera. Built by Westinghouse, it was a simple system which measured 11" x 6" x 3", weighed 7.25 pounds, and used 6.25 watts of power. It was capable of operating at 10 or 0.65 frames per second, depending on light level, and it had 4 interchangeable lenses. The camera was mounted inside the Modularized Equipment Stowage Assembly (MESA) in Quad 4 of the Lunar Module (LM) Descent Stage. This gave the capability of broadcasting the first steps of the astronauts as they climbed down the ladder of the LM at the start of the first EVA [extra-vehicular activity]. The astronauts would then detach the camera from it's [sic] mount in the MESA, mount the camera on a tripod, and carry it away from the LM to show the progress of the EVA.[emphasis added]
