Crew 172 Final GreenHab Report
GreenHab Status: at the moment the GreenHab is not a suitable place to grow any except the hardiest plants (succulents, lichen, etc.). Within a 24-hour period temperatures have gone from 25F to 101F. Once the A/C + heater are fully functional and both controlled by the thermostat and grow lights are installed, it will be a great space for plant growth and experimentation.
Advice for Upcoming Crews: if you hope to grow plants before environmental control is established in the GreenHab you should grow them in the main Hab. The Science Dome, even with the grow tent and grow light, is far too cold for most plants to survive during the winter.
Near-term Recommendations: beyond environmental control and grow lights, general work lights should be installed so crew can work in the GreenHab after dark, some sort of humidifier should be installed (though the full aquaponics system may add some much needed humidity to the dry desert air), and my inventory (or some version of it) should be shared with future crews: https://docs.google.com/spreadsheets/d/1VDX_qvZFgBNOkZdO3qbW_1xMkP3mFP2QSX7b_uhs-J4/edit#gid=0. If I had known, even a subset, of what the GreenHab had in stock, what its dimensions were, and its general state of affairs, I would’ve arrived at MDRS much better equipped to succeed. Fortunately I was able to get some useful information on current plant growth from the outgoing GreenHab Officer (Crew 171) and I did my best to provide that same service to the incoming crew (Crew 173).
Longer-term Recommendations: a future GreenHab Officer or MDRS should build some sort of ongoing environmental monitoring system (temp, humidity, sunlight, pressure, etc.), MDRS should establish standard forms that allow GreenHab Officers to pass forward information about current plants and request specific items to be planted by a preceding crew, and MDRS should make clear the overall goals of the facility (growth for consumption, testing strains resistant to harsh conditions, crew psychological benefit, etc.).
Summary: Once basic systems are up and running, such as environmental control and the aquaponics system, the GreenHab could be of great use to future crews and a major asset to MDRS. Until that time it is little more than a storage facility lacking accessible information on its current state, long-term purpose, and potential to facilitate crew research. For the sake and success of future crews I think solving these communication and information issues should be a high priority.
Ad astra,

Mission Summary – Final Commander Report
Ilaria Cinelli – Commander, Crew 172
Each generation of space exploration has had a focal point (reaching the Moon or building the ISS) and now it is Mars. Mars is not just the next goal. The Mars mission could be seen as a multilayer strategy which links the Moon, ISS and Mars exploration itself to resolve the major political, technical and economic problems a flight to Mars would engender [1].
Meeting the challenge for space exploration lies in expanding activities beyond the ISS. Nowadays, unlike the early stage of exploration programs, the international base of cooperation (the ISS) is the core for developing future scientific activities [1]. Exploration is an expansion of human experience in which international partnerships are needed to enhance the use of science and technology [1].The landing of the first human on Mars would be seen as an international achievement, born on strong scientific bases. This is the reason for which Mars analogue missions are fundamental. In extreme isolated environments on Earth, scientists and engineers challenge their skills and life for testing new protocols and prototypes that one day, maybe, will be used in a real Mars mission.
Research studies have been carried out to investigate the impact of isolation on human behaviour, factors and performance in different analogue environments on Earth for 14-days to more than 500-days missions. Long term isolation simulation experiments are aimed at increasing of physiological and technical autonomy of the Crew from the remote Mission Control Centre [2]. During these missions, the marsonauts are training to make a full use of the available resources and independence of decision making. Isolation is created by limiting the amount of resources available (such as food and water) and stopping the supplies [2].
Thanks to monotony, loneliness, lack of social contacts, high responsibilities and stress, researches show the development of successful strategies, increased confidence in performance, ability to independently deal with complex problems, higher levels of inner emotional energy, resistance to stress, increased internal control, and social growth in the Crew [2]. Lack of sleep, communicative behaviour and phyco-emotional state of the Crew are just a few of the stress indicators [2].
During my mission, I have seen these stages in my Crew. Most the members were beginners of the analogue environment and they have made great progress throughout the mission breaking their comfort zone, overcoming stress, increasing control and performance. The first negative emotional state was shortly balanced with the successful of the execution of teamwork tasks (such as refilling static tank with water, EVAs, engineering troubleshooting, TV interviews, cooking a great meal and others) and positive feedback from the terrestrial community and media. My judgement and words had a strong impact setting a good base for the mission.
In contrast with the early stages of this mission, my Crew become more and more independent of continuous communication using wi-fi. As you know, here at MDRS the internet service is restricted, except for a few hours during the night (from 2 am to 5 am). The needs of continuous contact with outside is due to an inner need of communication for a psychological support from trusted people (such as friends and family), compensating the emotional stress. At the end of the mission, their reports and communication with Mission Support are less personal, descriptive and with higher quality. Then, each of the Crew member better manage the use of the data needed for their personal communication. They have accepted the separation process and they now recognize this Crew as their own reference 24 H/7 in this mission. Although I have explicitly asked them to write about their personal view of this experience in reports and Sol summaries, most of them refuse because the mission itself is what they are. And that’s the right answer!
They stepped in the extreme environment of MDRS with new rules and scheduled tasks both during night and day. We started fixing the porch of the Hab even before bringing our personal items in, on the very first day! After a few days, we had four days of a critical situation both because of the weather conditions and stopping the water resupplies. This last event consistently contributes to increase the stress in the Crew, while a new balance was growing. With so many limitations, panic and complaints create a vibrant mood in the Crew and increase the need of communication about their needs and frustration.
Creativity is essential for surviving in this conditions! Creativity is needed to resolve technical problems, interact with the Crew, keep a good mood and motivation to perform the work program. Creativity is part of the adaptation process, as tolerance and flexibility. International Crews are challenging to manage more than the national ones, because of the different cultures. But they did it and I am proud of their efforts!
Facing a critical situation enhanced the feeling of a unique entity of the Crew. Even though they were stressed, they understood that we were equally affected by the lack of water and this sharing helped to de-tress. People can suddenly change their priorities when we teach them the right method.
Eight total projects have been completed during this two-weeks mission. Science, engineering and educational outreach were only a few branches of investigation. Carrying on a project in a Mars analogue environment implies dealing with strong weather conditions, basic technology, limited resources, no resupplies, limited external support and a long list of unpredictable events that might completely affects the outcomes of the research process. Although each of the Crew members is an expert in their field, the interaction and support between members both in the Hab and in EVA is the difference with the terretrial Labs. In my opinion, this challenge is the best part of the analogue mission!
As Commander, I consider this mission completed with successful outcomes. Seven strangers have now completed a great experience that I hope enriches their memories and soul. From Saturday on, we will go back to our terrestrial job… I do not like goodbye.
My Crew does not need me anymore. My work is completed now that their confidence in task is increased. I wish the best for them and I hope I helped them to reach their professional goals.
The Mars Society gave me the unique opportunity to be Commander, to training a fabulous international Crew, to manage the whole mission and to practice leadership at MDRS. I am glad I have invested so much energy and time such a wonderful experience! I thank The Mars Society, the volunteers and Mission Support for following and supporting my mission.
Commander Ilaria Cinelli is officially signing off.
“HabCom, it’s Commander. (…) Can you hear me? Mission is completed! (..) We are ready for landing!”
“Roger that, Commander!”

Troy M. Cole – Crew Engineer, Crew 172
“Personally, serving as Crew Engineer on Crew 172 has been one of the most fulfilling experiences I’ve done to date. I really pushed my engineering skills to the limits in a harsh environment and proved to myself that I have what it takes to excel as a field engineer.”
Nicholas McCay – Crew Journalist, Crew 172
“Being the Journalist for MDRS crew 172 was one of the best experiences in my life. It was lots of fun, challenging at times, and hopefully a stepping stone for me to working in the Space industry in the future. I believe our mission was incredibly eye opening in working with a diverse group of individuals and sacrificing your ego for the betterment of the team. “Whatever it takes” is a motto that speaks loud and clear to the needed adaptability in living/working in a hostile and at times stressful environment. I believe we succeeded in every way we could of as a crew. I will miss my crew mates, and the times we shared together in this unique”.
Pierrick Loyers – Crew Scientist, Crew 172
“I enjoyed this simulation a lot. For me, even if everything is not perfect, it has been a great experience. We encountered some difficulties but we managed to overpasse it altogether and this is an important point to me. We didn’t reach every points of our scientific objectives because of weather conditions but this mission has been very immersive and instructive, from a technical and human point of view.”
Patrick Gray – GreenHab Officer, Crew 172
“Despite difficulty communicating with MDRS management before the mission, limited information on facilities, and lack of feedback on proposed research (including the loss of four submitted proposals) I have had a deeply meaningful experience during my rotation at MDRS. Our crew had its share of issues and conflicts ranging from limited water to lack of sleep to language barriers, but we overcame these issues as a team and I loved learning about my fellow crew members and assisting in their research. The station has great potential and the full experience of suiting up for EVA and conducting research in the Martian analog environment is both scientifically worthwhile and personally breath-taking.”
Anushree Srivastava – Executive Officer and Crew Biologist – Crew 172
“Crew 172 is precious for me and will always be. Personally, after living 80 sols with an amazing team, coming back to the hab with a different team was a little challenging. They all were stranger to me and I was for them. But I think we all went through the process well, because we all had a single goal – a successful mission. We are the Mars Society Crew. I would say that I see an immense potential in every member of the crew. Illaria, a very responsible woman, can be seen mothering her crew members while performing her sleep enhancement study (she escapes from cooking :). Pierrick and Gwendal, two young professionals, amaze me. They are testing the Ground Penetrating Radar (GPR) to detect the trace of underground water! As well as, they are using 3D cartography system and simulating how an astronaut can get the altimetry data of a particular region on Mars. A completely new area of study for me. Patrick, an oceanographer by training, taking care of Martian plants, calm and polite, and last but not the least, is a huge lover of Indian food J Troy (our world famous Mr Helpful) immersed himself in making sure that all the systems inside the habitat work properly. He is an example of how a Crew Engineer should work during a “Mars” mission. Nick showed me an amazing world of virtual reality – an experience I was having for the very first time in my life. I remember when the first time he showed me Carls Sagan’s Why Humanity Must Explore the Unknown in his VR device, I was teary eyed.
Crew 172 is signing off but I hope that this journey is just the beginning of their journey to Mars!”

When you are on Mars… a short note after my 92 sols’ “mission”
By Anushree Srivastava
Crew Biologist – Mars 160 Twin Desert-Arctic Analog Mission
Executive Officer and Crew Biologist – Crew 172
You are on Mars.
When you are on Mars, life is unpredictable (just like on Earth, but on Mars, it’s a little bit more). I have always written about the beauty of this place; how those small portholes of our Martian cylindrical home let us gaze the surreal backdrop, make us immerse into our own sense of awe and appreciation. How our home stands tall against all the oddities of Mars. Living in this place, sometimes you feel that you are getting interviewed by your own sensibilities. You think that you are searching Mars, but instead, Mars searches you. I felt so. Why? because, it showed me, a new me (I keep saying that). It gave me space (but outside the small habitat 🙂 to emerge beyond me. That’s true. Even inside the hab, it gives you a wide space (really!!). I mean a wide space inside the very you. You learn to stabilize your emotional fluctuations by inevitably diving into the situational intricacies. Actually, it is a subtle process. And on Mars, you love being in this process, because then, you can see, that you are growing.
But, while witnessing all these nuances of living on Mars, something else dawns on to you at the same time. You come to know that Mars limits your extensions in so many ways. These limitations are accompanied by the fact that “it’s Mars, not Earth” – obviously 🙂 What I mean to say here, is that sometimes you feel helpless in absence of required supplies, breakdown of a system, inconsistencies in the communications and coordination with the team based on Earth, merciless whether preventing you from exploration and many more. As I said, because it is Mars, not Earth. It will pose its extremeness on you in some way or the others. You may think that we do have similar limitations on Earth, but they may not be curbed as swiftly and feasibly on Mars, as on Earth. Encountering these limitations is also part of this process of humans going beyond the human frailties – on Mars – I think. You rise. This transition is important. When you are on Mars, it may not be a picture perfect. And, when it is not, you have to live with it. So when you have all these lemons, you definitely learn to make good lemonade J
Here, my words are carrying the reflections of my own experiences during a long-term SIMULATION. I have not been on Mars, of course J but if ever I am part of a real Mars mission, I think these experiences will foster my time there.
Thee go to Mars, when Mars calls thee

“Quantifying patterns of diversity of halophiles at planetary analog site while simulating a human mission to Mars” – A quick recap
By Anushree Srivastava
Crew Biologist – Mars 160 Twin Desert-Arctic Analog Mission
Executive Officer and Crew Biologist – Crew 172
Recording the pattern of diversity of halophiles in the Mars analog environment of Utah Desert has been one of the prominent goals of Mars 160 mission. I was supposed to carry forward this objective using standardized microbial detection and identification methods as a Crew Biologist of both Mars160 mission and Crew 172. I performed field and lab work as Mars-based Astronaut-scientist living at the Mars Desert Research Station. All samples were collected in full simulation suit from different experimental sites chosen by our Mars160 Crew Geologist Dr Jonathan Clarke. Our research was conducted in collaboration with Earth-based remote science team Dr Kathy Bywaters of NASA Ames Research Centre via asynchronous communication. This work was important for comparison of science return.
My primary objective was to simulate the exact process of collection of soil samples and ancient gypsum deposits as how it is supposed to be done in the real Mars mission. Mars Desert Research Station has its laboratory, equipped with standard facilities required to perform basic microbiological experiments. Therefore, as Mars-based Astronaut-scientist, I was supposed to collect the sample and take them back to our laboratory to process them.
I performed the extraction of microorganisms from soil samples and then plating on nutrient agar. The idea behind extraction and plating was to observe the colonies growing at the particular concentration of sodium chloride (salt). My intention was to keep increasing the salt concentration to retrieve the rare ‘extreme’ halophiles for further molecular analysis. My samples included soil from the region of salt efflorescence and sulphur precipitation from different experimental sites. As well as, I plated halophiles from ancient gypsum samples that I collected during multiple extra-vehicular activities with Dr Clarke.
We have observed an interesting feature in the agar plates colonized by halophilic microorganisms at high salt concentration. We have found salt crystallization in some of those plates. According to Dr Rebecca Merica, an Earth-based microbiologist, media with high salt concentration is drying up and causing crystallization. These crystals could be halite. For me, the most fascinating idea is that the media which is crystalizing via evaporation has been colonized by halophilic microorganisms. So, they may have been buried inside those crystals during crystallization. Now, it will be interesting to record the time of crystallization and the prolonged duration of the entombment of halophiles. This study could be significant to assess the long-term survivability of halophiles buried inside evaporite crystals. This process is an important replication/simulation of the natural process of evaporation of sea water, crystallization of salt, and entombment of halophiles.
Ancient terrestrial evaporite deposits, brine, or salt precipitation are excellent analogs of astrobiological exploration of Mars. Scientists have proposed the presence of sulphate and chloride-bearing deposits on Mars (Vaniman et al., 2004; Gendrin et al., 2005; Langevin et al., 2005; Osterloo et al., 2008). Furthermore, perchlorate has been detected on Mars at a concentration ~0.5 % wt by Phoenix lander (Hecht et al., 2009). Interestingly, it has been shown that salty-water (brine) can occur on Mars due to mineral deliquescence (Davila 2010; Chevrier 2009; Zorzano 2009; Mölmann 2008, 2010; Fisher et al 2014) and any trapped liquid water (fluid-inclusions) in these salt deposits may potentially harbour either active or dormant microbial ecosystem on Mars.
The first phase of the Mars 160 mission and Crew 172 is over now. So, the unaccomplished science goals/experiments will be carried forward to the second phase of Mars160 mission, which is going to be conducted at FMARS in the Canadian Arctic in summer 2017. Furthermore, I intend to process the samples of gypsum deposits of Jurassic period (175-200 million years old) “back on Earth” in a highly specialized laboratory environment with Mars160 Earth-based scientists.

BEGIN TRANSMISSION
Today is our last day in Simulation. Tomorrow we will wake up in Southern Utah, and NOT on Mars. What a weird and surreal feeling…Just as our crew has hit our stride of living and working on Mars – we are leaving in less than 48 hours.
Our last day of SIM was one of the busiest since we arrived 13 sols ago. We woke up at the normal time of 7:30am and immediately got to work after breakfast. I am not going to miss dehydrated milk and cereal with weak coffee every day, but this morning we were treated to a delicacy on Mars that we have been saving the entire length of our mission – BACON & Eggs!!! Troy happily fried the strips and prepared the eggs. The HAB was overwhelmed by the delicious aroma of a quintessential American breakfast. Eating just two pieces immediately put most of the crew (Anushree is vegetarian, so she got extra oats and honey to compensate. She was content and had her usual smile.) into a tranced state as they savored each bite. Our operations plan for the rest of the morning consisted of finishing crew projects/reports, taking photos and videos for outreach, and another round of virtual reality for all the crewmembers.
The morning flew by and before we knew it lunch was being served. Anushree treated us to a delicious Indian dish of naan bread with vegetables mixed with Thai curry paste. This was quite possibly the best and also most “traditional” meal of our analog mission. The crew went to our space nap happy and full. This would be our last space nap, as tomorrow morning the sleep study will be concluded. The whole crew, myself included, hasn’t napped this regularly since Kindergarten. We all wish this was part of our daily schedule when we return back to Earth. I doubt the corporate ladder will agree, but that is a discussion for another day.
After our nap, the crew prepared for our last EVA. We were scheduled to do a short walk around of the close by Martian hills. As Pierrick, Ilaria, Anushree, and I donned our space suits we got the call from on-site Mission Support that our EVA would need to be cut short to only include our regular engineering check due to muddy conditions and impending weather. The crew wasn’t exactly ecstatic about this news as this was our last possible EVA, but in the end we followed mission support’s commands. A quick check of all the HAB life support systems along with a short walk around the MDRS campus was concluded in under an hour. Each crew member drank in the views and experience, as the next time we step out of the airlock will be without our oxygenator packs and bubble helmets. The realization of soon being out of SIM had started to sink in.
Once back inside the airlock with re-pressurization complete, the real work of the day started up again. The crew cleaned the entire HAB from top to bottom and sideways. A place, especially a confined place such as the HAB, can become quite dirty with 7 adults living in it non-stop for almost two full weeks. We knew we only had to do it this final time, so everyone bit the bullet and we were done in under two hours. With the freshly cleaned HAB, the crew settled in for dinner. Our last bag of tortilla chips, any kind of chips for that matter, and melted Velveeta cheese was our appetizer. (It is the simple pleasures on Mars that usually give the most reward.) Our last dinner as a singular crew was beans and mashed potatoes topped with corn. We ran out of actual dinner options many sols ago (other than lunch today which was saved as more of a “going away” meal), and we have been scrounging whatever we could find (typically topped with chips, cheese, hot sauce, and salt to make up for lack of variety). Again, the word – adaptation – just never ceases to be true here on Mars.
Our crew is a resilient one that has weathered many storms inside and outside of the HAB, personal or group, stressful situations and times of joyous laughter, but we are all stronger from this unique experience. One that we will all cherish for years to come. We hope you have enjoyed following our story. We have certainly enjoyed living through it – TOGETHER! Crew 172 signing off for good.
