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.

Comet PANSTARRS is delighting northern hemisphere viewers right now. But it's also big, bright, and beautiful to the STEREO spacecraft.

We don't have any spacecraft at Jupiter right now, which is a pity. Until we do, we have to rely upon Earth-based astronomers to monitor the changing face of the largest planet.

The news from the Curiosity mission today is this: Curiosity has found, at the site called John Klein, a rock that contains evidence for a past environment that would have been suitable for Earth-like microorganisms.

Nearly four decades before Curiosity, we dug into Mars for the first time. The pictures are still amazing.
