The case for water ice hidden in permanently shadowed regions at the north pole of the planet Mercury received another boost recently. On Wednesday March 20, 2013 at the Lunar and Planetary Science Conference, Nancy Chabot presented the very first visible-light images of what is in the shadows of these polar craters.

Curiosity is back to science operations, though the activities are limited in scope by the fact that conjunction is fast approaching. Here's a couple of neat images from sol 227.

Flash memory or computer problems oddly occurred on both Curiosity and Opportunity around Feb 27. One possibility is that a large solar flare resulted in radiation at Mars sufficient to temporarily corrupt the memory on both rovers.

The extended, mostly unedited recordings of my conversations with many of the people I spoke to at the ALMA Observatory in Chile. Also, the full English translation of Chilean President Sebastian Pinera's speech.

Really cool movies from Jim Richardson propose to explain how the same physics of impact cratering can produce such differently-appearing surfaces as those of the Moon, large asteroids like Eros, and teeny ones like Itokawa.
