From: AMASE - Arctic Mars Analog Svalbard Expedition
Posted: Saturday, August 18, 2007
I became more and more excited the closer I got to Longyearbyen, Svalbard. After a busy year working in the SAM Lab at NASA Goddard I am returning to the arctic as part of the Arctic Mars Analog Svalbard Expedition, otherwise known as AMASE 07. No longer a 'newbie' to AMASE, I know I am quickly approaching long work days, sleepless nights and instrument malfunctions. I am also approaching jovial camaraderie, new experiences and the most beautiful landscapes I have ever set eyes on.
The SAM team is participating in the second year of a three year grant to test planetary mission instruments and techniques in Mars analog sites on AMASE. Last year was a great learning experience as we set out into unknown territory with a brand new field instrument. We had a successful expedition, but as to be expected came up with a long list of improvements to our instrumentation and refinement of our science goals. After spending a year in the lab conducting organic analyses of our samples and designing and building new hardware, the SAM team is back in Svalbard to expand our exploration.
With increased capacities on all instrument teams this year, AMASE will be simulating rover mission operations as part of the expedition. This means a 'remote science team' will stay holed up on the ship while the cliff-bot rover from JPL is deployed in an unknown location. Using only images from the roverés onboard camera, the remote science team will drive around and select targets for sampling. Each instrument team will then analyze the selected samples to characterize the habitability of the field site. Conducting science through a rover's eyes is quite different than a human simply walking around a field site -- humans are able to turn and look at a moments notice and pick any number of rocks with their hands. Practicing rover science will be a useful exercise for the Mars Science Laboratory (MSL) scientists, in particular, who are looking forward to selecting targets through the eyes of the MSL rover in 2010. Steve Squyres, the Principal Investigator of the Mars Exploration Rovers (MER), has also joined AMASE this year to help direct and provide advice during this process.
I managed to get a window seat on the flight from Troms° to Longyearbyen. Most of Svalbard was covered in clouds this year so I did not get many views of the landscape. Just before landing in Longyearbyen, however, I caught a few glimpses of glacier filled valleys, dark moraines and barren mountaintops. Shortly thereafter the plane touched down and I was back in Svalbard!

About Kirsten Fristad in her own words...
Kirsten Fristad here again. I'm privileged and excited to be back writing Notes from the Field on AMASE 07. I am a planetary scientist working in the Sample Analysis on Mars (SAM) Lab at the Goddard Space Flight Center in Greenbelt, Maryland where I have been for the last year and a half. I graduated from Macalester College in 2005 with a major in geology and core in astronomy knowing I wanted to pursue a research career in planetary science. Through summer internships with several planetary scientists, I developed a background in analyzing martian and lunar planetary remote sensing data and Mars analog field work in Alaska. Over the last year I have continued to organize the Goddard/SAM Team contribution to AMASE, conducted organic analyses of AMASE samples, designed and built new field hardware and participated in two other expeditions in Utah and the Mojave.
Following AMASE 07, I will be staying on in Norway as a Fulbright Scholar to begin graduate work at the University of Oslo. I am very much looking forward to exploring more of this beautiful country, reconnecting with the country of my ancestors and filling up on pickled herring and lefse!
