Seeing Bases and Faces on Mars
Did you hear about Bio Station Alpha? No, it’s not a new video game. It’s a mysterious feature that someone spotted in Google Mars. In the northern hemisphere of Mars, at coordinates 71°49’22.11″N 29°32’35.64″W there is a cluster of white pixels just barely visible if you zoom all the way in. And obviously, the most logical expanation is that these pixels are a secret Mars base. Obviously. It is definitely not a glitch in the image caused by a cosmic ray hitting the detector and then exacerbated by compressing and map-projecting the image.

R.I.P. Spirit Rover
We all knew this day would come. Yesterday NASA announced that it would be stopping efforts to contact the Spirit rover after a final set of commands early this morning.

Results of the 5th MSL Landing Site Workshop
Well, after three days of fascinating science and heated discussion, the 5th and final MSL landing site workshop has come to a close, and the consensus is… that all of the sites are pretty darn interesting.

5th Mars Science Laboratory Landing Site Workshop Info
Hi folks, I don’t have much time to write a full post since I have some last minute changes to make to my talk before tomorrow morning, but I wanted to share some info about the workshop for those who want to play along at home. First, if you’re on the Twitter, there are several people at the meeting or following it online, using the hashtag #MSLsite. Speaking of following …

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!

Gale Crater Videos
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.

Why Read (Speculative) Fiction?
Today I gave a two-part guest lecture to a bunch of Cornell freshmen. The first part of the lecture was The Science of Red Mars, which you can read about over here. But since this writing seminar (taught by my officemate) might be the only course that some of these students take which involves reading fiction and writing about it, my officemate encouraged me to talk a bit in general about reading fiction, and particularly speculative fiction. I figured that since I already put together the guest lecture I might as well post it here!

New CO2 Reservoir Discovered on Mars
If you’ve followed Mars science for long, you know that the question of where the atmosphere went is a major one. Evidence points to liquid water on the surface of Mars, and that’s only possible if the atmospheric pressure is high enough and the surface temperature is warm enough. Adding CO2 to the atmosphere would increase both temperature and pressure, so a lot of scientists have been looking for carbonate rocks that might be trapping the CO2 that used to be in the atmosphere.
Well, this week a new article in Science reveals that there is a huge amount of CO2 trapped as dry ice near the South Pole!

Dreaming of Easy-to-Use Data
Some thoughts on how difficult it is to use multiple different types of data in planetary science, how easy it could be, and two free programs that are important first steps in making easy-to-use data a reality.
