How scientists are working with CRISM, an aging but still exceptional spectrometer on Mars Reconnaissance Orbiter, to find the rocks where Opportunity's work will tell the story of ancient water on Mars.

I'm returning to the deep dive into the literature that began with articles about lunar basins and then explored the geologic time scales of Earth, Moon, and Mars. Now it's time to catch up to the last decade of Mars research and learn what "phyllosian", "theiikian", and "siderikian" eras are.
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.
I just sat in the "small bodies" session at the Lunar and Planetary Science Conference, listening to three talks about Phobos. The first was by Abby Fraeman, who looked at data on Phobos and Deimos from the two imaging spectrometers in orbit at Mars. The next talk, by L. Chappaz, was motivated by Phobos-Grunt's mission. It asked: if you grabbed 200 grams of soil from the surface of Phobos, how much of that material would actually have originated on Mars? Then there was a particularly interesting talk that dealt with the question of how Phobos' grooves formed.
Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.
Laser beams and space exploration are perfect for each other, and not just because all self-respecting starship captains know their way around a blaster. It turns out that zapping rocks with a laser is not only fun, it also can tell you what they're made of!
A recent entry by Bethany Ehlmann from the blog of the Planetary Geomorphology Working Group of the International Association of Geomorphologists demonstrates how you can combine the power of different types of data to tease out a rich story of the past history of one spot on Mars.
