Yesterday I participated in a telecon about Gale Crater, one of the potential landing sites for MSL. It’s a fascinating place to talk about and would make for a spectacular mission. Ok, this is true for all four finalist landing sites, but the scenery at Gale, with its 5km tall mountain of layered rocks would be particularly great. One of the presenters at yesterday’s telecon, Dawn Sumner, posted two very nice videos on YouTube covering much of what she talked about. The videos also serve to show off a very-cool new open-source 3D visualization and GIS tool called Crusta being developed by a student at UC Davis.

Have you read the book Red Mars yet? If not, you can download a pdf of it here. It’s a classic hard sci-fi epic about the colonization of Mars, and for my latest post over at Science in my Fiction, I took a look at how the highly accurate depiction of Mars in the book has held up with all the new discoveries in the last 20 years. Head on over and check it out!

More on the cryosphere of Mars, along with some speculation about martian carbonates and skepticism about the presence of methane in the martian atmosphere.

Greetings from Texas, loyal readers! As you may have noticed, this year’s Lunar and Planetary Science Conference came and went with barely a peep here on the blog. This is because, unlike some members of the planetary science community, I do need to sleep occasionally, and I spent almost all of my time at LPSC either in sessions or working on my never-ending paper. Yeah, remember the one that I …

Yesterday I had the opportunity to give my first ever “webinar” to a group of teachers and some of their students, and thanks to the miracle of the internet, the whole thing is recorded so you can watch it too! Shoshe Cole, another Mars graduate student here at Cornell gave the first presentation, focusing mostly on general Mars background info and the current Mars Exploration Rovers. My presentation starts at just shy of 1 hour into the recording, and I talked about Mars Science Laboratory and my involvement in the mission through ChemCam work and landing site selection.
We also both included some career advice for the teachers to pass onto their students, so if you or someone you know are interested in a career in planetary science (or science more generally), you might want to take a look!

Now that it’s a New Year, it’s time I wrapped up my AGU 2010 recaps. This post covers Wednesday and Thursday, with lots of good stuff about super-earth exoplanets, impacts on the Moon and Mars, and lasers on Venus!

We wrapped up the landing site workshop on wednesday afternoon by revisiting each of the four sites and discussing them in turn. Unfortunately, the way that we did this was very disappointing, and made for a frustrating afternoon. The discussion was centered around a word document that was projected up on the screen in the room. Over lunch, the meeting leaders had conferred and listed what they thought were the …

The final site of the four that we discussed yesterday was Eberswalde, which of course is interesting because of the big delta that is preserved in the western part of the crater.The first presentation on Eberswalde was an impassioned and really interesting talk by terrestrial geomorphologist Bill Dietrich. Bill talked about how Eberswalde is an excellent site for going beyond just making qualitative statements about water on Mars and actually …
The second site that we discussed yesterday was Holden Crater. Ross Irwin gave the first, overview presentation. Holden is a 155 kilometer crater that formed right in the middle of a huge drainage system that spans from the Argyre basin to the northern plains, and at Holden you would land on a bunch of coalescing alluvial fans on the western crater floor and then drive southeast to access some nice …
Holy cow. Today was jam-packed with interesting stuff about Mawrth Vallis, Holden Crater and Eberswalde Crater! I took tons of notes, and I will try to use those to assemble a coherent picture of what was presented and discussed today. But if you’re too impatient to wait for me to work through those and post the more coherent summary, here are the notes in their raw and unedited form. Read …
