"We hope to learn how often big rocks crash into the Moon since we're sending astronauts back," Could the answer be 5 or 6 times on some days?
To: blam
The kinetic energy can easily exceed the explosive potential of that amount of TNT. Do not scorn kinetic energy!

Question.
Can entropy be reversed?
To: blam
The Moon's atmosphere is negligible.Is "none" negligible?

Several thousand times a year? But - What size of impacting rocks should they worry about?
How big an area is the primary impact - and how big is the secondary (splashback) rock impact area?
Compare the area of the moon with the area of the landing craft and shelter itself: Probability of impact - even with an enhanced affected zone - is very very small.

Deep underground.
No other way.

My job had a 'ringside seat' view of the Geminids.
Unfortunately, we also had cloud cover that night.

Of course, it happens during a part of every engine cycle.
To: Red Badger
But when the last star blinks out and the dregs of energy diffuse..can entropy be reversed?
When in doubt ask Asimov!

And the computer said,"Let there be light!"...And there was light..........Asimov.........

Saw the Geminids in the bleakest part of West Texas one year. Absolutely and simply indescribable, even for one whose vocabulary is as awe inspiring as mine. (joke, joke) I'm astounded that traveling to remote parts of the country to see such things isn't as popular and unremarkable as going to Disney World.

I think it was Heinlein that had the loonies digging deep trenches, then putting in floor, walls, and ceiling, sealing it up, and pushing the overburden back over the completed tunnel.
A good job for a robot trencher! Too bad we're sending people back first. Putting the same money into teleoperated robots would get more work done, since the robot would not need air, or water, or sanitary facilities, or food, or much radiation shielding. They could operate two or three shifts and "sleep" during lunar night. If we could land a nuke plant there we could fuse the lunar soil into building panels with another remote factory (much harder to to than a digger I think). Then, when people show up, they use the panels to line the trenches and caulk them tight.
Ooh, ooh, I know! Build a Space Shovel!
You still need to know how deep to make the trenches, but there is a cutoff point where it does not matter- imagine being at ground zero when Tycho was made!

I've had the rotten luck of being stuck in the southern portion of 'upstate NY'...
Meaning Southern NY to the 'rest of the country'.
Why is this rotten?
Because for the past 8 years there has been rain, fog, or some form of weather interfering with visibility every time there is a meteor shower.
I got lucky once and saw comet Hyakutake.

Is "none" negligible? What's the minimum amount of "gas" that has to be present to be considered "atmosphere"?
There's evidence of earlier outgassing on the lunar surface.
Did any of the Apollo missions think to bring back samples of the atmosphere?
To: Darksheare
You probably already know this, but even if it weren't foggy, etc., you get poor visibility because of city lights. Go to the remote regions and it is something you will NEVER forget. I rank it right up there with seeing the Grand Canyon.

I'm in the cow country area of southern NY, Orange County section.
Plenty of darker areas there.
But... the weather stinks.
