Today we continued to process the soil samples taken at each of the 12 transects we conducted over the last few days. In the Science Dome, we measured the pH and salinity and characterized the texture of the soil samples. These data will be used to characterize the ecotones of the deserts around MDRS in an upcoming paper.
We continued to collect new plant specimens opportunistically, including an annual invasive grass, (Annual Wheatgrass – Eremopyrum triticeum) newly recorded for MDRS.
We plan on continuing our lab work and wrapping up data recording for the plant project tomorrow.
Greenhab Report – April 18th
GreenHab Officer: David Murray
Environmental control: Ambient, fan on from 0930 to 1900; the door closed.
Shade Cloth: 80%
Low Temperature: 24 C
High Temperature: 33 C
Relative humidity: 15%
Hours of Supplemental Light: 0
Daily Water Usage for Crops: 38 L
Water in Blue Tank: Refilling tank in about one hour
Time(s) of Watering: 1030
Changes to Crops: The tomatoes didn’t like the heat today but they’re alright. Tomato starts haven’t shown much growth but everything else is responding very well to the fertilizer.
Narrative: The door was left closed with the fan on high from 0930 to 1900 with passive exhaust as part of an experiment. The internal temperature stayed warm but fluctuated less drastically than it usually does with the door open.
Although the high was above 30 degrees C, I think the average temperature was right around perfect for all of the crops but the tomatoes (and possibly the beans).
Harvested basil, sage, carrot, and parsley.
Harvest: 7 g basil, 7 g parsley, 15 g carrot, 1 g sage

Sol Summary – April 18th
Crew 210 Sol Summary Report 18-APR-2019
Sol: 5
Summary Title: Live from the surface of Mars
Author’s name: Paul Sokoloff
Mission Status: Nominal
Sol Activity Summary: This morning through to early afternoon our crew participated in a Livestream with Discover the Universe, engaging over 150 classrooms live with a presentation and Q and A about Mars, the Mars Society, and MDRS. This presentation will soon be uploaded to YouTube where it will continue on as a legacy outreach component of crew 210
(http://www.discovertheuniverse.ca/workshop/special-webinar-live-from-mars-april2019/).
After a water run into Hanksville, our team continued to process our field samples in the Science Dome and will continue to do so tomorrow. By recording physical characteristics of the soil samples taken from our quadrats, we hope to discover the factors driving plant diversity (or the lack thereof) in the different ecological areas around MDRS.
Look Ahead Plan: We plan on continuing our work in the Science Dome tomorrow and will work on putting together a plan for our multi-year biodiversity inventory.
Anomalies in work: No issues.
Weather: Bright and sunny all day.
Crew Physical Status: Good.
EVA: We presented out Livestream from the area just north of "Zubrin’s Head" on the west side of Cow Dung Read, south of the blind corner on the road.
Reports to be filed: GreenHab Report, Operation Report, Science Report, Daily Photo Report
Support Requested: None.
