Narrative: The A. thaliana experiments will be concluded tomorrow with final results available in the mission summary. The tomatoes and sugar snap peas are visibly looking much better, likely due to the decrease in watering frequency and allowing the soil to aerate. The yellow pigmentation is decreasing and they are more stable in their stem structure. 16.4 g of dead biomass was groomed from several of the plants, including the sugar snap peas.
Fallen material was removed from the surface of the soil to prevent the growth of fungi or other contamination. This material was dried out in the Science Dome oven and this data will contribute of our ISR cellulosic ethanol study. 3.2 g of sage and 8.0 g of basil were harvested for soup and pizza. Similar to yesterday, the door remained closed for most of the day due to the low ambient temperatures and snowy weather.
Harvest: 3.2 g sage
8.0 g basil
Support/supplies needed: None.
