Like many of us this summer, NASA’s Cassini spacecraft has

been doing some sightseeing, though I suspect few of our vacations can rival

the tours of NASA’s Saturn-orbiting probe.

Over the weekend Cassini sent back

pictures of its visits to the Saturn moons Enceladus, Tethys and Dione. 

It sure

puts my shots of Hoover Dam in perspective.
