Mars Desert Research Station Crew 165
— End of Mission Summary —
Merged Crews; Team Tharsis II and Team Nippon.
Rotation Dates: March 5th-20th, 2016
he MDRS crew 165 is an international collaboration between North America Team Tharsis II and Team Nippon from Japan. Pamela Nicoletatos and Ken Sullivan were returning MDRS members from Crew 149; Eriko Moriyama, Masashi Hiraki, Ryoko and Tomoya Mori were new to the MDRS facilities and SIM experience and were mentored by representatives from the Japanese chapter of The Mars Society. We had the intentions to conduct six main projects during our rotation however due to time restrictions, third parties and logistical constraints some of these had been put on hold for a future date.
and SIM outreach program:
Our first project was to establish a Mars and SIM outreach program for students, granting insight to the opportunities and daily challenges within the SIM experience that are plausible factors when pursuing the prospect of interplanetary colonization. This however was a project we were unable to complete due to last minute equipment failure the day before our rotation began. We did in turn utilize our Crew Journalist and focus on social media outreach opportunities such as Facebook and Twitter to document the adventures of the crew. Feedback and responses to our experiences have been exceptional and extremely positive from around the world.
Environment Control and Life Support Systems simulation software:
The next project was a study dedicated to the analysis of realistic human activities and their impact on water, food and waste systems. The crew was closely monitored through daily water and food intake; water consumption for cooking and weight measurements for meal wastes, along with biological waste data that was collected through weight analyses. This data will be analyzed with a Japanese designed ECLSS (Environment Control and Life Support Systems) simulation software, to compare a human influenced environment cycling system with that of the pre-simulation data calculated with theoretical figures. The simulation results will be used to investigate whether or not the initial framework and calculations were close to the actual crew metabolism and be applied to the software algorithm to improve the accuracy of simulation. This project can contribute to the future manned space missions especially in closed-loop ECLSS such as a base on Mars.
Survey for presence of Human derived bacteria in both protein utilization and non-protein utilization bacteria in and around the HAB:
Our third project focused on the human footprint a crew/colony would have on an existing extraterrestrial environment, and which human associated microbes might be more prone to flourish in such harsh and extreme ecologies with a focus on both protein-utilizing and non-utilizing bacteria.
Rover Data collections and samples of bacteria and protein present in the surrounding “Martian” terrain had to be modified due to the failure of the arrival of our rover unit to the MDRS facilities. This project was modified however to allow for the retrieval of soil samples by a member of the crew.
Soil samples from 6 locations around the HAB, even in the designated septic containment area seemed to suffer little contamination by human derived bacteria, much to the Crew’s surprise. However it was discovered that there were a few natural bacteria with low-level detection in soil samples collected from these areas. On the contrary, soil collected from Sentinel Hill’s peak (A popular location both for MDRS crew members for EVA and tourists), showed high levels of both protein-utilizing and non-utilizing bacteria, however the bacteria present was not human-derived in nature.
It was concluded that due to species of grasses and moss, which grows in Sentinel Hill’s summit, and while there were no plants in the other sample areas, Sentinel Hill’s peak has proven one of the best habitats for the presence of natural bacteria around the HAB be it of non-human origin. Overall it seemed to provide feedback that indeed Humans at the MDRS facilities had little to no impact on the ecology of the site. It would be interesting to analyze the soil component differences between Sentinel Hill’s summit and other areas. One additional factor to be taken into consideration would be climate conditions and how much influence they may have on the dispersion of foreign microbes within any given environment. (Future Project?)
Additional Mission Goals
It has been an honor to be a part of Crew 165 and an experience of a lifetime. Appreciation for their hard work and dedication cannot be described.
Members of Crew 165, may our paths cross again!
