Correction, Hubble is more like 400 miles closer to the moon than the earth's surface.<br />Sorry, faulty memory<br /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Regarding the laser reflectometers, the Apollo mission left a few, too.<br />I don't think that's what the question was.<br /><br />I was not aware of the rovers you mentioned. I'll look them up now!<br /><br />Thanx<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

It's in a ~ 570 km orbit. That is about 340 miles.<br /><br />Distance to moon is approx 250,000 mi.<br /><br />So 340 miles out of 250000= 1.4%<br /><br />MW <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Sorry about the incorrect labeling of the "moon rover". I should have said moon dunebuggy, or moon quadrunner, or moon ATV. ;-)

EdwinGene:<br />What about multiple-telescope arrays...<br /><br />Me:<br />There was some talk of using the ESO to image human lunar artifacts a couple years ago. At the time, it was claimed that as an interferometer, the 4 giant ESO scopes had a good chance of seeing the LM descent stage and maybe the rovers.<br /><br />I have seen nothing since and I think the ESO scopes are able or should be able to be operated in an interferometer mode by now. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

No biggy, it just confused me.<br />As it turns out, there were rovers after all! <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Yes the first robotic rovers where used on the moon and not on mars. Also the Soviet did it long before NASA did anything like that. I wonder why they never get credits for that.

It's been asked in this thread, but I do not remember anyone answering: While LRO be able to image any landers, impact sites, or rovers on the moon? <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

Getting back to the original question, <img src="/images/icons/smile.gif" /> LRO is supposed have a resolution of 50 cm. The minimum widths of various spacecraft on the Moon follow.<br /><br />Large Lunas 4 m<br /><br />Lunakhods 1.6 m<br /><br />Surveyors 4 m<br /><br />Apollo LMs 9 m (excluding legs)<br /><br />Lunar Rovers 1.8 m<br /><br />All of these are larger than the 3 pixel minimum needed to get a discernable shape. The shadows cast by these craft should also be very visible.<br /><br />Jon<br /><br /> <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

How about the various impact sites? We know the mass of a S-IVB. We also know the speed and trajectories that each S-IVB was on when it hit the Moon. If we can locate the impact sites, we can then compare that to craters of unknown origin. <div class="Discussion_UserSignature"> <hr style="margin-top:0.5em;margin-bottom:0.5em" />Will Pittenger<hr style="margin-top:0.5em;margin-bottom:0.5em" />Add this user box to your Wikipedia User Page to show your support for the SDC forums: <div style="margin-left:1em">{{User:Will Pittenger/User Boxes/Space.com Account}}</div> </div>

The Saturns were only used for launch to LEO, I think.<br />Don't believe they made it to the moon. <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

Most of the IVB's were crashed on the Moon to provide seismic signals for the seismometer arrays. I have no idea of the size of rater but they would be substantial, I think, given an empty stage would have weighed ~15 tonnes, as i recall.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>
