GreenHab Report – May 17th

Crew 281 GreenHab Report 17 May 2023
GreenHab Officer: Megan Kane
Environmental control: fan with door open
Average temperatures: 90.38
Hours of supplemental light: None
Daily water usage for crops: 1.72 gallons
Daily water usage for research and/or other purposes: NA
Water in Blue Tank 174.19 gallons
Time(s) of watering for crops:
0800: refilled 8 water bottle (4 L) watered other plants as needed 1.5 L
1505: refilled 1 water bottle (500 mL) watered other plants as needed 500 mL
Changes to crops:
Average temperature was the highest it has been since we started. The highest tomato leaves dropped a little during the hottest part of the day but there is no sign of wilting. The plants are in good condition.
In the morning the greenhab was checked and watered as required. For plants without a passive watering system, a dowel rod was used to perforate the soil crust in 1-3 places per planter to allow the water to get down to the roots more efficiently and reduce evaporation.
The morning was a bit hazy and the temperature during the initial test of the airflow diverter went well. However once the haze dissipated the interior quickly rose in temperature. Opening the door after the test had a slight effect. The Crew Engineer and Greenhab officer looked at the evaporative cooling system to see if it could be utilized as we have entered the time of year and weather conditions where it would be effective. It was determined that we would need to reach out to mission control and that setup would likely require an EVA.
This afternoon ingredients for making a marinara sauce were harvested.
There is concern about the lack of humidity in the greenhab and the increasing temperatures.
Harvest: (include which crop and mass in grams)
Tomatoes 514
Basil 1
Sage 1
Chives 7
Oregano 1
Thyme 1
Support/supplies needed:
We request additional information on evaporative cooler including:
· Make and model
· Date last used
· Status when last used (operational or broken)
· Method of connecting the system to a water supply and which one.
