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. Another Phil |

LROC is bolted to LRO, so, like MRO with HiRISE, to image off-nadir you have to command the spacecraft to cant over one direction or the other. I would fully expect them to be able to not only successfully target any known landing site, but to nail it pretty much dead centre.

I would fully expect them to be able to not only successfully target any known landing site, but to nail it pretty much dead centre. There are always map uncertainties, but in the case of the Apollo landing sites the ALSEP laser retroreflectors allow very accurate knowledge of the site position in the Earth reference frame. But I believe the spacing at the equator orbit to orbit is about 30 km, so slewing off-nadir would be required for arbitrary targets. -------------------- Disclaimer: This post is based on public information only.
