Changes to crops: None

Narrative: I scrapped 2 of the cucumber experiments and set the plant material aside for later analysis. We prepared some wet mount slides and analyzed the samples under the microscope in the science dome and found nothing unusual with regards cell structure. However, the discoloration and dry material leads us to believe that they died of nitrogen deficiency and improper watering. We will continue analysis at a later date. I am attempting to salvage three of the cucumbers that appear to still be living. In addition, I prepped the tomato pots so they are ready for the seed arrival.

In the large planter, we dug up all of the carrots that were growing wrong areas and replanted them in one section (as I mentioned in my last report, they were clearly taking over the planter and causing nitrogen deficiency on the other crops). In the rearranging process, we freed up a lot of room for the tomatoes in the planter and we intend on using some of the seeds we received to add to the number of tomato plants in the planter.

I also harvested many of the larger carrot crops and we separated the carrots from the carrot greens. We dried out the greens using the ovens for our In Situ Resource Utilization (ISRU) study on cellulosic ethanol production (see the GreenHab section in the mission summary report). The harvest is being used for roasted carrots for dinner!

I started autoclaving pipet tips and microcentrifuge tubes, however, we had issues with the autoclave (refer to tonight’s operations report). Once the autoclave cools, later tonight we will start the procedure for germinating the Arabidopsis thaliana seeds and plating on the germination plates. We will put those plates in the GreenHab and expect germination within the next few days. Today, we started sampling regolith on EVA for later physical property characterization. Once the A. thaliana germinates, we will transfer the seedlings to the regolith we identify as the best substrates.

Harvest: Carrots: 314 g total weight

124 wet weight of carrot greens

190 g of carrots

23 g dry weight of inedible cellulosic material

Support/supplies needed: None.

Narrative: The carrots appear to be dominating their portion of the planter and seem to be drawing nutrients from the adjacent oregano and parsley. Tuesday, we will harvest some of these carrots to help alleviate the stress on the rest of the grow bed and provide supplemental nutrition to the crew. The cucumber plants are dead and we will recover them and repurpose the soil for the incoming tomato plants at the beginning of sim tomorrow as well. We changed the fly paper in all of the pots and grow beds, and we took photos of all of the plants in the GreenHab to compare when we photograph them again several times throughout the sim.

Harvest: None

Support/supplies needed: I suggest purchasing packages of fly paper in the next few weeks, there is only one left.

Narrative: We are having change over today, I am feeling so emotional to leave my kids(plants) in the hands of a new green officer Mr. Nathan Harland. I am sure he will take care of them and make them grow even better. Plants are growing as expected and looking forward to seeing their status in near future. Thank you MDRS for this amazing experience. This is going to be a life long experience. Thank you for everything.

Narrative: Out of all the sprouts, fenugreek sprouts have grown faster. Cover shaped leaves are about 5 cm high till today and growing, which make a pretty groundcover between taller, widely spaced crops. and the fact that fenugreek roots are capable of fixing nitrogen in the soil to naturally fertilize the crops around them. All these make the crop a perfect all-rounder.

Harvest: None

Narrative: Today was the blissful day for us in midst of winds. We learned that Gardening is the most therapeutic and blissful act we could do. It made us forget every difficult weather conditions around. We were enjoying the smell of things in soil, by getting dirty without feeling guilty. It took little time to grow sprouts but one tiny leaf appeared from one of sprout as a light of joy with a new era of life. And slowly-slowly browns started turning into greens with a sprinkle of water and martian warmth.
