Utah Mars Analogs

Greetings from Los Angeles! I’m in California this week for the 5th and final MSL Landing Site Workshop. Since that is sure to provide some tasty blog-fodder, I thought I should sit down and write about my trip to Utah two weeks ago.

Why did I go to Utah? Because the latest MSL camera team meeting was held in Moab, and I was hoping to give a brief presentation about some work I’ve been doing on the side (in all my copious free time) with the calibration data for the Mastcams. Unfortunately, I can’t write about what happened at the business part of the meeting because then I would have to kill you. Or more likely Mike Malin would kill me. It turned out there wasn’t time for me or my adviser to give our presentations, but it was still a great trip because after the “sit in a room all day and watch powerpoint presentations” part of the meeting, came the field trip!

It’s a very bizarre texture. It cuts across the layers of the rock as if it is related to fractures, but it is often deformed and …

Here’s the second of my recent Universe Today Articles: scientists have discovered new deep sea vents in the Caribbean that will teach us more about sunless ecosystems. Good to know if we ever want to look for life in the oceans of Europa some day! Check out the article here.

Spirit Rover Discovers Carbonates

Big news from Mars today, Spirit has found evidence for significant amounts of carbonates in the rocks of Gusev crater! Carbonates are really important for two reasons: first of all, Mars has a very thin CO2 atmosphere right now. Too thin for water to remain as a liquid on the surface: it would just boil away and freeze at the same time! But there is lots of evidence that water …
