Supplemental light: 4 hours (10pm-2am)
Harvest: Yes. 99 grams of tomatoes, 26 grams of lettuce, 30 grams of carrots, 26 grams of spinach, and 8 grams of kale microgreens. Total: 189 grams.
Summary of ScienceDome operations: GHO Officer Tyler Hines’ experiment is continuing to be monitored; cress microgreens have been harvested. Forty Long Duration Exposure Facility seeds were relocated to the Greenhab and are sitting on a shelf in a wet paper towel in order to further support the germination process.
Dual split: On a timer from 10pm to 7am and under Mission Support supervision.
Summary of RAM operations: No operations were conducted in the RAM.
Summary of any observatory issues: One side of the dome is not opening because the straps that provide tension for the doors were wrapped around the motor. The stress on the straps is severe enough that there is no way to release that tension to try and rewrap it. The crew has been informed that the MDRS Observatory is inoperable until further notice.
