John,
You got one of those funny little hammers?
We're running low on those hammers. All the monofuel
Humvees are checked out for months in advance. However,
there are five solar-powered inflatable-box RV's sitting
in the shed having the dust cleaned off. They're available.
They make about 250 klicks a day with their 30 square
meters of panel. They follow the GPS Autotrails, and if
you see anything interesting, you can stop and let it
charge while you bike over and check it out. With those
high fat knobbly tires, you can cover a lot of ground in
0.37 gee just by pedaling.
If you decide to stay out past the 30-day mark of the RV's
supply inventory, the flyers can drop you a Supply Ball,
but you have to chase it down after it finishes bouncing!
The RV's hold four, so bring a couple more geologists and
a paleontologist. Maybe you'll find the first fossil.
Sounds good, doesn't it?

EP,
All the theories in the world added together do not amount to one
fact.
But since we do not have ANY facts about the impact
rates on the Moon (or Mars or Titan or Ganymede or
anywhere at all and only inferential data for our own
home planet), the sum accumulation of facts is... ZERO.
We ain't got one fact.
And the contribution of reason / inference from
known quantities amount to considerably more
than zero.
Am I not the the one who is always saying, about
endless speculation about the geology of Mars or
asteroids, that we will never know until we have
"boots on the ground," 100 geologists on Mars-suits,
carrying those funny little hammers, and scooting
around in monofuel Humvees, living in solar tents?
Until then...
Sterling K. Webb

Hi Sterling -
Usually, you are spot on, but in this case...
In fact, no one knows if the Earth sweeps stuff up for the Moon, or
the Moon pulls in more stuff that hits the Earth. NASA's garbage
estimates for ELEs are a perfect example of how bad their "modeled"
impact estimates are; NASA's estimated human ELE rates are even
worse - they appear to be off by two orders of magnitude.
Earth impact rates need to be determined from Earth data. Then a
more general model may be worked out, using accretion data from all
bodies in our solar system.
All the theories in the world added together do not amount to one
fact.
As far as the effects of hyper-velocity dust goes, I seem to recall
parts of Surveyor being examined after lunar surface exposure.
all the best,
