they should post in advance the time they are doing this so we can go outside and wave.


what are the chances that MSL will be able to resolve the moon too?

As a matter of fact, right now, Mars is in a gibbous phase as seen from Earth. Only about 84% of the planet's disk is illuminated by the Sun as we look at it now. (For comparison, if you look at our Moon tonight [18 June], it's about 88% illuminated.) So, we can/could see an appreciable terminator separate from Mars' limb. However, with Mars only about 10" of arc in diameter as seen from Earth at present, you'd need a scope on the order of magnitude of Hubble or Keck to see Olympus Mons casting a shadow.
