The Dawn spacecraft has taken some great images of 4 Vesta over the last year... ...and since it's now making its way to Ceres this'll be the last of them we'll get for a while: http://dawn.jpl.nasa.gov/multimedia/ves ... allery.asp Figured they'd make great reference material for PA's asteroids if Uber haven't seen them already and of general interest to everyone else.
The Moon by Lunar Reconnaissance Orbiter http://wms.lroc.asu.edu/lroc_browse Clicking any of the images gives you a zooming interface that lets you see fine (~0.5m/pixel) detail of the lunar surface. It's like strategic zoom... If you'd rather see the Moon through fancy videos: http://svs.gsfc.nasa.gov/vis/a000000/a0 ... index.html In fact with all the data that NASA has collected on the Earth, Moon, and Mars, I don't see why modders couldn't import them into PA ^^.
