Targets for LRO Options

[PhilHorzempa]

You can imagine this to be a companion thread to the one requesting suggestions
for MRO targets on Mars.

The LRO (Lunar Reconnaissance Orbiter) is set to launch in a little over a year
from now. There was to a be a site selection workshop in May 2007, next month, but
I see now that it has been cancelled. Therefore, it appears that it is up to us, the UMSF
Community to take up the baton and help NASA out. It was done for New Horizons at Jupiter
and was very productive.

So, what are the sites that you would like to see imaged at 0.5 meter resolution by
LROC, LRO's High-Resolution camera?

My first suggestion would be to re-photograph the Surveyor 1 landing site to compare
it with the images obtained by Lunar Orbiter 3.

My second suggestion would be to photograph the Surveyor 6 landing area. This
should image S-6 itself, but even more interesting, it may capture images of
Surveyor 4, which should be only a mile or so away. This would help to
determine whatever happened to S-4, which abruptly stopped transmitting just
short of touchdown.

I want to clarify something Doug just said, citing Don Wilhelms: "the Moon is better observed, geologically, at lower resolutions."

Don did write that, and nobody would know it better than him. But he was talking about recognizing geologic units - areas of different origin or composition. It doesn't apply to things like block size distributions, small fractures etc. - see the very high resolution panoramic camera images in "Apollo over the Moon", for instance, with very narrow recent fractures in the regolith in Mare Serenitatis. We would also do better with much higher resolution images of Ina! I expect the LRO images will be very useful and probably surprising in many ways.
