Site 2 - Deildarthunguhver in Vesturland
After the muddy waters of Seltun, I was looking forward to some clearer waters to sample. I got my wish granted at Deidarthunguhver. This hot spring is extraordinary. Water emerges out of the rock bubbling and fountaining furiously at 98C, at the highest flow rate in Europe. 198 liters / second (52 gallons per second)! …Continue

Site 1 - Seltun, Reykjanes Peninsula
After loading our trusty 4x4 Suzuki Jimny with our sampling gear, we headed off heading west from Reykjavik. Leaving the highway to go in the direction of Kruysuvik, the paved road soon ended (I love that about Iceland, the driving is always so much fun!). Thankfully the rain had stopped by the time we got to our destination, which was…Continue

Well time has once again escaped me and the rest of the HI-SEAS crew as we find ourselves with 19 days left inside our simulated Martian home. As we begin to wrap up all of our projects, papers, and final outreach activities the crew has achieved a state jovial exhaustion coupled with some mild panic at the growing to do lists.
Even with our long days and short nights the crew has still been finding time to explore the local terrain and this morning performed a…

Iceland 2014 - Overview of field work
In 2014, I was very lucky to be a recipient of the Lewis and Clarke Fund for Exploration and Field Research in Astrobiology. The fund is awarded by the NASA Astrobiology Institute and the American Philosophical Society (more info here). My proposal involved sampling six hydrothermal sites (fancy…Continue
Upon waking my first thought was of home. Right now at home I would be waking up to the insistent, but loving cold nose of my half husky puppy informing me that it is time for a long jog. I would grab my running shoes, my pup’s leash, and some dried fruit as I head out the door for a nice long sunrise run. Like normal I would watch the sun coming up over the tree tops of my favorite park, feel the cool breeze mixing with the heat of the first rays of sunlight, and know that sense of…Continue
The air pumping into the helmet is cool and refreshing, with just a tinge of plastic smell, my torso is cool thanks to cool water running through the tubing in a garment known as a liquid cooling garment. Entering into our airlock I seal the main habitat off from the Airlock by connecting the Velcro on one layer and zipping shut the second. Turning I can see my EVA companions one, like me, in a fifty pound University…Continue

Hey SAGANet friends!
I hope you all had an excellent Earth Day on April 22nd. Did you all hug a tree, ride a bike or read the Pale Blue Dot monologue by our main man Carl Sagan? I tried to hug a tree, but my arms wouldn’t reach (clearly I’m awesome at jokes). Although I’m really far away from land,…Continue
Hey SAGANet friends! Julia here, I'm one of your admins and normally I operate out of Denver, Colorado, but currently I find myself on a ship in the Pacific Ocean just under Tokyo, Japan. I’m onboard a drilling ship called the JOIDES Resolution acting as one of two Education Officers on Expedition 350 – Izu-Bonin-Mariana Rear Arc.

A Brief Look at how Analog Space Suits Help to Develop Future of Planetary Extra Vehicular Activities
The Hawaii Space Exploration Analog and Simulation (HI-SEAS) study currently being conducted on the slopes of Mauna Loa focuses on human factors and group cohesion. Both of these focuses are vitally important for Extra Vehicular Activities (EVAs) and for future planetary exploration; providing constraints that could make or break a mission. The Apollo missions broadened humanities…Continue

Last Thursday I had a great conversation with some BMSIS researchers during the monthly Beer with BMSIS about science funding and academic salaries. I posted a quick blog article on the subject and decided to try cross posting here. My apologies if its a bit off topic, but I hope people find it interesting. I couldn't get the figs to formal right, if you want to see them the original post can be found…Continue

The first official week of the 4 month HI-SEAS mission occurred Saturday April 5th and was celebrated with a much needed day of half rest. Week one was filled with setting up our new home and adjusting our mind sets from instantly having knowledge only an internet search away to informational access being a full 20 minute delay one way. After the initial period of adjustment the crew busily began settling in and connected internal network servers, repaired Extra Vehicular Activity…Continue
The official first day of training began this morning and for the first time all six crew members were meeting face to face. After months of talking through Skype, instant messaging and on the phone we were all together and ready to tackle the first day of training. The morning began with a brief physical fitness session and some breakfast followed by a 9:00 AM briefing about the main focus of the 120 day Mars simulation study.
This study is funded by NASA and is a 1.2 million dollar…Continue

Hello, my name is Tiffany Swarmer and I am one of six crew members preparing to enter a 120 day simulation in an analog habitat on the slopes of Mauna Loa, Hawaii. This mission is intended to study the various human factors that contribute to crew/astronaut function during an isolated mission to Mars. Along with studying human factors many technologies such as Google glass, 3-D printing, Extra Vehicular Activity (EVA) equipment, exercise clothing, and many more technologies will be…Continue
I await your comments my friends. Thanks.

Sorry I haven't posted for a while. My muse sort of went into hibernation for a bit after my general exam. Actually, I suppose this particular blog would be a collaboration between muses, if we're going with the classical categorizations: Euterpe (lyric poetry), Urania (astronomy), and sometimes Thalia (comedy.)
Anyway, here's a sonnet inspired by the Radiative Transfer (that is, the interaction of sunlight and infrared radiation with the atmosphere) course I'm taking this…Continue

I had a discussion earlier on a thread on Facebook concerning the future of humanity. Some people asserted that we will eventually understand every mystery of the universe – but will we truly?
Right now the human race is growing rapidly, both in population and in technology; both are equally scary. Will we grow to the point where sustainability is not feasible? Will we not be able to feed ourselves? The opposite end holds technology; will we be able to combat the rising problems of…Continue

I wrote this while my friend and colleague Marcela Ewert presented her work at her Ph.D. defense. She's been doing a lot of really cool work about how Arctic microbes make their living despite the temperature and salinity extremes found in the sea ice and in the snow that rests on it. Here's a link to some of the work included in her dissertation.
Jargon note: exopolysaccharides, also known as…Continue
Fourth day of sampling at Yellowstone National Park
Thursday yielded another fun set of adventures in Yellowstone! Kirsten and I joined up with Arizona State University students to go sample a remote site, Obsidian Pool, near Mud Volcano (a popular spot for Yellowstone visitors). …Continue

Third day of sampling at Yellowstone National Park
- July 2013 -
Wednesday brought new experiences with hot springs. Eric took us to Sentinel Meadows, an area of the Lower Geyser Basin with several spectacular springs, including Flat Cone, Steep Cone, Mound Cone, and Queen’s Laundry springs. Steep cone is an approximately 15 feet tall cone formed by sinter deposited over…Continue
