Commander's Report

Judah Epstein Reporting

Crew 97 has returned back to Earth. As of 15:00 today, the crew ended Simulation and was able to walk outside without the constraints of a spacesuit.

Crew 97's final day in Simulation consisted of continuation of scientific experiments and EVAs. Inside the Hab, today was extended psychophysiological analysis on each crew-member with 11 minutes of exposure three times throughout the day to digital images and sounds and white screens to define emotion on three parameters of cognitive/psychological, physiological, and social.

Final testing was completed on the slow sand filters with extended tests including bacteria results. Additionally, the GigaPan 360 degrees panoramic camera of the Sandstorm Rover was successfully tested.

EVAs today consisted of Satellite data comparison and data collecting in collaboration with a fellow scientist, as well as GigaPan testing.

The crew is completing their final night at the Hab with preparations for tomorrow's crew handover and a final crew game of Imaginiff for our psychophysiological analyst to compare with the results from the Imaginiff game from the crew's first night at the Hab

Science Report 1

Judah Epstein Reporting

The purpose of this project is to explore the effectiveness of a slow sand sedimentary water filtration system in a planetary environment. To simulate a planetary environment the experiment is conducted at the Mars Desert Research Station, a self-sustaining planetary research experiment and simulation expedition.

Background information regarding the project abstract, purpose, goals, and specific experiment details and information are included in the Science Report from January 6.

Data collected from Jan 14 and prior is available in this spreadsheet.

Updates on results:

Filter 1 (Martian Simulant) and Filter 2 (Commercial Sand) are not achieving optimal results as the filter is clogged with extremely low hydraulic conductivity. Therefore not enough effluent water was produced to take measurements with the Qanta probe (Temp, SpC, DO, pH, TDS, DO%, ORP).

Turbidity results: Turbidity of effluent from all three slow sand filters has generally been increasing. Turbidity of effluent from the wetland, greywater, and Hab potable are remaining generally consistent.

Based upon results from the experiment it was determined that the slow sand filtration system is not a suitable replacement or backup for the wetland system. But it was determined that the slow sand filters do significantly increase the water quality versus greywater. Therefore, in an emergency scenario, slow sand filtration could be used as a backup to supply influent toilet water if the existing Hab water filtration process has failed, such as in the scenario of a long-term power failure. The advantage of the slow sand filtration system is that the system requires no electrical or power input.

Additional and extensive analysis will be completed on datasets collected from the experiment for a more thorough review and interpretation of the data.

Science Report 2

Tonya Thompson Reporting

I performed a psychophysiological test of affective response to digital images and sounds on each crewmember 2 times today. The images were projected onto a simulated 3D surface and the sounds were played through headphones.

Each crewmember sat in the test area in my stateroom for 11 minutes (a 3 minute pre-exposure baseline, a 5 minute affective images and sounds exposure, and a 3-minute post exposure measurement). During this time, I measured the crewmember’s heart rate variability and skin conductance level in response to the digital images and sounds.

I also had each member complete a Cohen’s Perceived Stress Scale questionnaire after dinner.

Science Report 3

Lucinda Land Reporting

I started the morning taking imagery of the crew doing their morning exercises. I wanted to get used to using the equipment before taking it out on sim. It is the Gigapan camera developed by Carnegie Melon University in collaboration with NASA and the Intelligent Robotics Group. The idea is that the Gigapan is mounted on top of Sandstorm as it does its EVA's. It can take high resolution imagery of the area and geology.

Using it inside the Hab is easy. The Gigapan walks you through the steps and you can use all types of cameras with it. It does have small buttons and a difficult to reach battery connector which made it difficult setting it up outside the Hab while in sim.

We took a Panorama image of the crew this morning doing our exercises after breakfast. We a had a lot of fun with that. It was a quick capture since it was just a panorama which took about 40 shots in total.

Outside the Hab while on an EVA with the XO and the Commander a 360 degree panorama was taken. This was definitely more difficult. Using the gloves to handle the Gigapan was difficult with those tiny buttons. Connecting the batteries is difficult with the hidden compartment where the batteries are stored and needing to be attached to the motherboard. The space is limited for ungloved fingers and with gloves on was frustrating but after many trials the connection was made. I would advise practicing this part with gloves on before going on an EVA.

The camera took a 360 degree panorama and captured about 117 shots in all of an area just east of the Hab. These images will be stitched back together later. Tomorrow, we will travel to a higher location where a 360 panorama of the Hab and larger area of our location will be captured with the rising sun. We'll need to get up early for that.
