Commander's Report

Judah Epstein Reporting

Today was Crew 97's last full day in Sim. The team continued scientific experiments of psychophysiological testing and water filtration analysis. EVAs today consisted of Rock Varnish collection to test for signs of life, satellite data comparison, and Water Gully analysis.

The crew received their initial Alpine Aire dehydrated foods and have begun to enjoy the new foods and ease of preparation. Additionally, the hot water heater is now functioning and therefore the crew have begun to take showers (whereas past shower opportunities were skipped because of the freezing cold water).

In the Greenhab, the top layer of clogged sand was removed from the strainer tank to increase flow rate of the greywater filtration system.

The crew is now preparing for their final day in Simulation with a morning and afternoon EVA before the scheduled 3:00pm return back to Earth.

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 12 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.

Science Report 2

Tonya Thompson Reporting

I performed 3 psychophysiological reading sessions on each crewmember today. Each session lasted 3 minutes.

The crewmember entered my stateroom, sat in a chair, placed finger sensors on their 3 middle fingers, and watched a white image projected onto a wall for 3 minutes. During that time, I recorded their heart rate variability (HRV) and skin conductance level (SCL). The data for each session was saved to the hard drive of a desktop pc in my stateroom.

I also had each crewmember fill out a Cohen’s Perceived Stress Scale questionnaire at the end of the evening after dinner.

EVA 27 Report

Jim Crowell Reporting

Time: 09:40 / 11:55

Crew Members: Jim Crowell, Nathan Wong

Site Location: South of the Hab

Transit Mode: ATVs / Walking

Objectives: To take two panoramas south of the Hab

Results: Both desired locations reached and panoramas taken.

Lessons Learned: Even if failed on the first attempt, by looking for an alternative, one can accomplish what is needed. One of the pans needed was at the top of a mountain. After the first attempt to reach the top failed, another way up was sought out and found.

EVA 28 Report

Amanda Damptz Reporting

Time: 2:05 pm to 3:09 pm

Crew Members: Jim Crowell, Nathan Wong and Amanda Damptz

Site Location: North East of the Hab

Transit Mode: ATV

Objectives: Take photographs of gullies and collect rock varnish samples.

Results: Three photographs of gullies taken. GPS coordinates taken. Two samples of rock varnish collected.

Lesson Learned: The wrong type of rock hammer was taken out delaying the sample collection process.
