We're in Costa Rica, and there's an ongoing festival called Día Nacional de los Boyero (National Day of the Oxcart Driver). lots of local color amid the festivities, and this street parade -- called a Masquerada -- was a typical example. Note the brass band in the background.

The Moon, up close and personal. I'm looking at a tiny, 0.4-gram sample of lunar dust collected by Apollo 17 astronauts in 1972. None of the particles are larger than 54µm (0.002 inch) across. This is just the sort of stuff being studied at the Colorado Center for Lunar Dust and Atmospheric Science (, where I'm participating in the #LASPnewmedia workshop. Thanks to Bob King ( of the Duluth News Tribune for letting me post his image.
