Commander's Report

Franco Carbognani Reporting

You already know. We care a lot about our "spirulina babies". To let them grow comfortably we have built a nice nest inside the Green Hab were temperatures remain the optimal ones.

This morning has been spent with the final filming for the Arte Television documentary. For us it has been a very interesting experience and the television crews was very satisfied with what they have filmed.

We had lunch together and they get their chance to appreciate our pre-prepared food.

Today the Monitoring and Alarming System we have setup during our rotation has been extended in order to get real time Proton Flux data from the GOES Satellite and corresponding alarms have been setup.

The Crew can now receive early Solar Storm Alert via smart-phones and look for shelter in time

Greenhab Notes/Comments:

Gray Water System: The Trickle Reservoirs are filled with gray water.

Pumps running fine and water circulating. Can we start feeding water into the aquatic tanks?


For our biological experiments we needed very stable temperatures in the range of 27.5 - 28.5 C° and sunlight (no possibility to use the incubators). The temperature of the Green Hab revealed to be not stable enough in particular considering the very large external temperature excursions of those days. The best we could do is keeping the Green Hab thermostats to the "propane saving" setting (50 F°) and we have setup a small thermo-stabilized volume by making use of the hardware brought onsite for the Monitoring project (PLC) and our biological instrumentation.

Science Report (Window seal Inspection)

Angeliki Kapoglou Reporting

MDRS design encompasses two big circular window panels, three side windows and a top window on the second floor. On the other hand, there are five small circular windows on the ground floor there.

After inspection it was confirmed that the windows seals, especially the two circular on the second floor, are not tight, they suffer from wear and a dislocation of the glass like-material, subjecting the airspace to the surrounding environment.

Failure was probably caused due to the use of hard adhesives which do not compensate the different thermal expansion coefficients of the metallic frame and the glass window. Another problem is that cheap vinyl windows will disintegrate from the UV exposure.

That means that the vinyl expands so much that it doesn't hold the seal in place properly. When the seal fails, there is no insulation, causing less energy efficiency. Although the rest of the windows panel appear to be in a better condition is very possible that they will experience seal failure in the near future. Windows at MDRS were also examined for evidence of water vapor condensation. None of the windows appear to suffer from moisture buildup during the current weather conditions. Instead MDRS has a very dry indoor atmosphere, which is perhaps a reflection that the structure is not perfectly sealed and allows air exchange with the outdoors.



Science Report (Physiology)

Kavya Manyapu Reporting

Description

Long duration space flights expose human body to microgravity which affects the physiological health drastically because of the absence of loading on the body due to gravity. Some of the physiological effects

that result from human space flights are bone loss, muscle atrophy,cardiovascular deconditioning, altered sensory motor reactions, fluid redistribution/orthostatic intolerance etc. In order to counteract these changes and increase astronaut performance in orbit, cardio vascular exercises as well as resistive exercises has been made a part

of the International Space Station missions. Although a 2.5hour time frame of exercise is being dedicated everyday on the Station as a countermeasure for preventing bone loss and muscle atrophy, exercise

has not fully prevented musculoskeletal deconditioning on ISS. All the data from the spaceflight studies suggest that significant changes in

the present exercise protocol should be made in order to prevent musculoskeletal deconditioning as well as new and efficient ways should be considered in order prevent physiological deconditioning during space flight especially when we are aiming for long duration

missions going to Moon and Mars.

For missions to Mars where astronauts are exposed to microgravity, etc for longer periods of time, very efficient fitness regimens such as exposing crew to artificial gravity, exercise and vibration need to be established. There are many studies being performed to learn and test the efficiency of such measures presently by NASA and other institutions.

For MDRS, the scope of the project was to measure the physical fitness of the crew before the beginning of the mission and compare it with their physical fitness during the time of the mission and towards the

end of the mission. EVA performance over a period of 15 day rotation at MDRS is also being studied using feasibly measureable markers that represent the stress levels of the crew. Since this mission is not

independent of earth’s gravity, the scope of the project has been reduced to conducting physical fitness examinations and measuring the aerobic capacity of the crew using measurable parameters with the use

of simple equipment. Because of the constraints of the mission and the unavailability of exercise equipment and accurate bone loss measuring

devices, the scope of the project has been reduced to measuring the parameters noted below.

The measurements are taken before the start of the mission and are compared to the measurements throughout the mission as well as towards the end of the mission. Although, the tests conducted are not fully representative of a true Mars mission simulation, these measurements are believed to assist researchers in the future to devise efficient exercise protocol to minimize health effects in astronauts and increase their performance for long duration missions.

1. Weight

2. VO2 max

3. Lung Capacity

4. Bone Mass

5. Muscle Mass

6. Compare how exercise effects Crew performance (specially during EVA)

Procedure

First the 6 crew is divided into 2 groups,

1. Group 1 performs cardio and resistive exercise protocol ranging from 30-50 minutes daily.

2. Group 2 would be sedentary, not performing exercise Initial baseline measurements were taken for all the crew on day 1 of the mission. Consecutive measurements on each day are collected 3 times when required for some parameters, 1) morning (resting heart rate) 2) before exercise 3) after exercise/EVA

EVA performance

The crew has to be very productive during space missions. The productivity and the performance of the crew depend on not only the nutritional intake, workload etc but also the physical fitness of the crew as mentioned earlier. The heart rate is one of the approximate measures of stress levels. The heart rates of the crew were measured on a daily basis as well as before, during and after an EVA.

Correlating the physical fitness data and the human factors performance test data (collected by J.Deaton) that include workload, memory retention, mood scale, sleep scale and logical thinking, the effects of exercise on crew performance will be predicted. The

comparison between the two groups (exercise and no exercise) is being performed. This comparison might serve as showing that the physical fitness of the crew increases with exercise and also helps in the reduction of stress levels while performing EVA.

RESULTS

Since this is still an ongoing experiment, the data will be analyzed after the end of the mission and will be coordinated with data collected by J.Deaton for the EVA performance. However, some limitations are faced by the project as listed below Limitations and Lessons learned

1. The sample size is very less to establish any concrete data

2. The simulation time of 15 days is also very less to notice significant changes

3. The demographics and the physical fitness of the individual crew before the mission is quite variable, this will certainly make the data skewed.

4. It is recommended that MDRS have basic exercise equipment, specially a treadmill /cycle since not all the crew participating at MDRS are able to perform intense cardio activity involving various moves

5. The study of the effectiveness of various resistance exercises for the lower extremities could be performed (such as investigating bone mass increase performing two legged squats versus one legged squats) to device exercises that best prevent bone loss in astronauts. But in order to perform such experiments the study should be run for longer

periods of time.

All these experiments might not mimic the desirable techniques and results that would be helpful to design regimens for counteracting musculoskeleton deconditioning for missions to Mars. However, it would give a basic idea of how physical fitness will play a major role in astronaut performance for long term missions and what kind of excercise protocols would best fit countermeasure program. Also, it

has helped the crew to understand the importance of physical fitness and be able to squeze in time for excerise amidst their busy schedule, since for human space flight excerice is not a choice, but a necessity.


PS: It will really be good to have long term study on this subject and incorporate it int eh MDRS simulation someway since not all the crew are familiar with it as well as it the 15 day rotation is nearly impossible to get any good data.

Journalist Report

Kavya Manyapu Reporting

Today was the final day for the French crew filming Crew 102. The weather has not been favoring the crew today and the last few EVAs have been postponed for tomorrow. However, one EVA was performed later

today when the weather was much more favorable. This EVA was used to track solar storm shelters, commanded by F.Carbognani and accompanied by

Y.Brodsky and A.Kapoglou. The science reports are being finalized.

The commander is putting together a final report with inputs from the rest of the crew with their respective projects. It has been a very successful rotation/simulation for the crew considering the number of constraints, breakdowns in the habitat etc. The last days for the crew are a bit stressful trying to close all the loose ends for the experiments.

T-3 days to return to Earth, and the crew thinks that they have only spent a very short time on the Red Planet. Good luck to the crew for the return planning.
