AGU 2009 – Day 1

For those not familiar with the conference, the fall meeting of the American Geophysical Union is a terrifyingly, overwhelmingly large conference. Each year, something like 16,000 geoscientists descend on San Francisco to share their work. It is also one of the major planetary science conferences, so a lot of new results are first presented here. This year, the first talks that I checked out on Monday were about radar observations …

Sand Dunes Quote

Briony has kindly updated my last Mars Art post, adding the sand dunes quote which I referred to. In case you don’t feel like going back to look at that post, here’s the quote: In places vast accumulations of sand weighing millions of tons move inexorably, in regular formation, over the surface of the country, growing, retaining their shape, even breeding, in a manner which, by its grotesque imitation of …

We had another great day at Great Sand Dunes National Park and Preserve today, with lots of pictures, but it also involved a lot of hiking and I’m tired. So instead of a full post, I will refer you to my adviser’s post about our first day at the dunes, over at the Planetary Society blog. I’m also stealing the image that he posted over there, comparing granule ripples on …

Sand Dunes!

Greetings folks! I’ve been silent for a few days because I am in the midst of a lot of traveling. On Monday, Tuesday and Wednesday this week I was at a team meeting for the Mars Color Imager (MARCI) and Context Camera (CTX). Rather than spend a lot of time explaining what that means, I will do what I always do and link to the planetary society blog. My adviser …

Phoenix's Neighborhood (Part I): The Basin

If you’re like us, you’ve been refreshing the Phoenix news page constantly, looking for the next update from Mars. If you need a little catching up on what’s going on in the mission, here are some recent posts with updates. But with all the Phoenix coverage, there hasn’t been much talk about the context for the Phoenix landing site. What’s so cool about the north pole of Mars? The north …
