Adding to Linda's statements...
1. There is only 1/6 as much gravity to accelerate against to get to orbit. (the escape velocity is much lower, too.)
2. They dropped hardware (stages) that was no longer needed so they would not have to waste fuel accellerating it.
3. There is no air resistance for the engines to compete w ith.
4. Because there is no air, the LM did not need to be aerodynamically shaped.
5. The LM did not have to endure atmospheric reentry back at Earth.

I love it when Dave says "MAN! Okay Houston the Falcon is on the plain at Hadley."
There is just something I find very endearing about that announcement. A little more endearing than Neil's announcment "Tranquilty base here, the Eagle has landed." Although I often quote both those announcements almost pointlessly in my daily speech.
P.S.: We went to the Moon.

I had often wondered why he said..."MAN"...like that.
I think it stems from them having the hardest landing. The A15 pilot has the honor of shutting off the rocket motor the quickest of all the missions. Result...the longest freefall. Combine that with one of the legs being in a crater and the LM winding up out of level. I think they were surprised.

I think the one thing us Americans can be proud of is our space program. It is unmatched.
I can't wait until the shuttle fleet is retired and the Constellation Program finally begins.
Something to note ...( 1 month ago by philkarn)
Something to note about the liftoff: several large thermal blankets go flying off to the west. You can even see their shadows on the ground. One actually flies over the ALSEP before landing and stirring up a little dust as it does. How could a flimsy piece of foil fly so far in an atmosphere at 1 g?
DUST you say ...( 1 month ago by imnazhole)
DUST you say philkarn, and ON THE MOON? So 1/6th the force of earth's gravity is enough to force a single spec of dust quickly to the surface after it has been disturbed? How do you get sand and dust on a planet or satelite with no atmosphere??? Hmmmmmmmmm???????????????

I can't tell if it's "Man!" or "Bam!". The ALSJ has the latter. They did have the hardest landing just as you said. Yet still, none of the legs "stroked". I guess the LM design was pretty conservative.
It's not sand. The ...( 1 month ago by philkarn)
It's not sand. The dust was created by a steady "rain" of micro meteoroids churning up the surface over eons. Look at it with a microscope and you'll see sharp shards and beads of glass formed by shock and heat.
The dust fell quickly to the surface because there was no air to impede its fall.
The moon is an alien place. It doesn't behave as your uneducated intuition says it should. It *does* behave as real physics and math says it should.
Orbital velocity ...( 1 month ago by philkarn)
Orbital velocity for low lunar orbit is about 1.5 km/sec compared to about 7 km/sec for the earth. Energy goes as velocity squared, and the mass ratio of a rocket goes up exponentially with the required change in velocity.
All these combine to make it possible to achieve lunar orbit with a single stage and a very modest mass fraction.
Oh no! They could ...( 1 month ago by philkarn)
Oh no! They could have cast a 36' tall astro-NOT on a set scaled up 6x so it would only LOOK like the pendulum was swinging in 1/6 g. It's just more proof of a HOAX!

Many Apollo cameras ...( 1 month ago by philkarn)
Many Apollo cameras used wide-angle lenses to simplify aiming and increase depth of field.
Get a camera and a wide angle lens. Take pictures of objects and their shadows across the entire field of view. Are the shadows all parallel?

While I'd rather visit an asteroid, it would indeed be fun to go back to the moon. A whole new generation could follow it just as my generation followed Apollo.
I especially look forward to vastly better communications. Continuous HDTV plus lots of realtime high res digital photos would be quite doable with the same power and antennas.

My friend and I put a rock band together a few months ago and I picked the name. I wanted to call it "Good Luck Mr. Gorski" (lol) but that's been taken by about a zillion indie groups. So I was watching this video and decided how about "Ascension"? This is also a common name but not nearly as common as the aforementioned where we live.
P.S.: We went to the Moon.

I've always ...( 3 weeks ago by philkarn)
I've always wondered why the landing dust isn't uniform but goes out in rays. Maybe it's "shadowed" by rocks? The rays do seem to deflect with horizontal LM motion, which suggests rock shadowing.
But I've also seen randomly moving ray-like plumes from onboard cameras looking down Deltas when they're above most of the atmosphere and the plume billows outward.
