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.

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.

On Thursday at noon PDT / 1900 UTC I'll report on some of my favorite findings from LPSC, and answer your questions about the latest planetary science.

Some interesting results from the Lunar and Planetary Science Conference on clay minerals on Mars and what they might mean about ancient water.

Reports from the March 19 session at the Lunar and Planetary Science Conference covering eight icy moons in the outer solar system: Ganymede, Europa, Dione, Rhea, Mimas, Tethys, Enceladus, and Miranda.

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.

A new slant on Martian landscapes from Mars Global Surveyor.

A mind-boggling quantity of information is being presented at the Lunar and Planetary Science Conference. In my first report from the meeting, I try to make sense of the Curiosity and Opportunity sessions.

Some lovely, rarely-seen images from the MESSENGER mission.

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

This week I'll be talking with NEOWISE principal investigator Amy Mainzer about moving objects that the WISE mission has spotted both inside and outside our solar system.

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.

Great dinner and great conversation with staff of the National Radio Astronomy Observatory, topped by Chile's national drink.

Another audio blog post, with excerpts from the National Science Foundation briefing on the ALMA Observatory, edited while I was waiting for my planet to Chile at LAX.

The European Space Agency (ESA) announced the list of instruments selected for its JUICE mission to explore the Jovian system for three years starting in the 2030 following a 2022 launch.

Ever wonder what it would taste like if you could lick the icy surface of Jupiter’s Europa? The answer may be that it would taste a lot like that last mouthful of water that you accidentally drank when you were swimming at the beach on your last vacation.

As February turned to March, Opportunity was conducting some of its final science investigations on Matijevic Hill, the MER team was making preparations for the robot field geologist's trek south for the next winter, and the Mars Exploration Rovers mission was checking off another month of exploration.

Last week the Curiosity mission made its first data delivery to the Planetary Data System. The bad news: none of the science camera image data is there yet. The good news: there are lots and lots of other goodies to explore.

Over the last few days the mission has been working its way through its first major (not life-threatening, just really inconvenient) anomaly: a memory problem in its main computer.
