Travel Day 2: Moon and Mars greenhouse in the Arctic?

Yes, it's true.  At Iqaluit Airport, waiting for our connecting flight to Resolute Bay, the Spaceward Bound Arctic group met Matt Bamsey, a post-doc from the Canadian Space Agency.  Matt's work involves researching how to develop autonomous greenhouses for use on the Moon and Mars.  The reasoning is that on those missions we don't want astronauts spending a large percentage of their time growing food necessary for their survival during long-duration expeditions.  So, if greenhouses can be developed that run automatically, and can handle the unique light and dark environs of both the Moon and Mars, astronauts have more time to devote to the science goals of the mission.  Search terms such as "Arthur Clarke Mars Greenhouse Haughton Mars Project Devon Island" for more information.

Why the Arctic?  Moon: extreme environment.  Mars:  extreme environment.  Arctic:  You guessed it.  Extreme environment.

Spaceward Bound's Web Guru


Here's Linda Conrad, of NASA Ames Research Center.  She is THE guru when it comes to Spaceward Bound web postings.  And she laughs a lot, so she is a valuable part of the expedition team.  She will help with questions and comments we receive while in the Arctic.

Mars Science Laboratory & Wind Tunnel


Phoenix, the rover currently at the north pole of Mars, and Spirit and Opportunity, the two Energizer Bunnies of Mars' rovers, all carry science packages weighing, I believe, less than 20 pounds each.  Flying to Mars soon will be the Mars Science Laboratory.  Carrying about 143 pounds of science equipment, this rover will be the size of a small car!  How do you gently place this payload on the martian surface?  Well, boys and girls, with science, technology, engineering and mathematics saavy, of course.  That and all the amazing folks at NASA and supporting contractors.  

For an exciting .mov animation of its landing, go to mars.jpl.nasa.gov/msl/gallery/video/movies/MSLAnim1.mov

Last week, I was fortunate to tour the world's largest wind tunnel where tests were being conducted the main chute for the Science Laboratory.  It's sixty feet in diameter when fully deployed, leaving ten feet of clearance on each side of this 80' x 100' wind tunnel.  Look for the people walking in front of the wind tunnel intake in the photo outside the tunnel.  Gives one a good perspective for the actual immensity of the tunnel.


Rover Driver's Ed. 101


One of the six major questions of the Arctic 2008 expedition is:
How can a teleoperated rover be used to assist human explorers in the Arctic?

Yesterday, I journeyed to the Carnegie Mellon University Innovations Lab to begin to learn how to drive a rover.  After driving a rover I find it's similar to driving a R/C (radio-controlled) car, or operating a video game controller.  An aside:  I can hear my video-game-loving students already concocting stories to their parents explaining why they can't do their homework, but must get on the Wii.  They have to refine their fine-motor teleoperational device abilities so as to ensure a career in the sciences...(weary sigh from teacher).

Above you can see a rover similar to the type we'll drive in the high Arctic.  Also, below, in the video, you'll meet my driving instructor, Andrew, and catch a glimpse of the lab staff.  Incidentally, this biologist notes they seem to fuel their metabolic rate primarily through candy bars and highly-caffeinated soft drinks.

Carnegie Mellon University rover

Here's a view of a rover being debugged and prepped for Spaceward Bound usage by the Carnegie Mellon University group pictured below. 

One week to Axel

Geoff Hammond and Robert Palassou were at
NASA's Ames Research Center the week of July 7
meeting with Chris McKay, principal investigator of the Spaceward Bound team, observing construction of a rover for use in the Arctic by a group from Carnegie Mellon University, attending astrobiology lectures, and researching methods to best share the Spaceward Bound experience with teachers and students from all over the world.  They will develop educational activities from Axel and share them virtually via the open-source websites.

Past Spaceward Bound Sites

Here's some video of the cushy base camp we had at Spaceward Bound Mojave 2007.  This facility is run by the California State University system for the benefit of researchers working in the Mojave Desert.

The temperature and precipitation extremes of this locale readily suit the Spaceward Bound
goal of searching for life in extreme environments.
