Actually landing is the easy part. They crashed an expensive pile of scrap metal into Mars last Christmas, very adeptly. Landing intact however, might be a bit harder for the EU'ies.

Except this was an ion engine. Not very practical for short hops to the Moon and such. However, across the solar system they shine.

I still favor VASIMR or NERVA myself. Possibly using ion engines for lateral thrust and/or monoprops (hydrazine with platinum/iridium catbeds) for attitude control or quick rotations.
