Changes to crops: I removed the tomatoes and prepared the soil for the
next seeds.
I harvested carrots.
Radishes are germinating.
Red lettuces have some problem growing up, and are still not red.

Narrative:
The monitoring of the fan that I made yesterday worked well today, and
helped control the heat, even if it is still really hot when the sun
shines. Maybe, in the next weeks, I will put on the cooling system.
Indeed, it appeared that for a moment the temperature increased even
with a fan at max speed.

I also discovered that the "Crew 205 ‘s mystery seeds" were… radishes
! So I pulled out some radishes from this planter to allow the biggest
ones to grow.

Radishes from my experiment have a great germination : more than 75% of
the planted seeds have germinated, with an average of 2.6 cm of height.

Harvest: 9.0 g of basil, 2.1 g of parsley, 31.4 g of radish, 2.3 g of
lemon basil

Support/supplies needed: None.

Narrative:

After the morning EVA, I harvested some herbs for our lunch and some carrots for our dinner.

In the afternoon, I prepared the soil for the next tomatoes seeds and removed the old ones.

Finally, I monitor the fan in the Greenhab to avoid high heat in the morning. It will now be turned on from 8 to 16, for 15 min every 15 min. It worked pretty well today!!

The door was opened from 0730 to 1700.

Carrots replanted yesterday don’t all look great.
Tomatoes look great, but in two pots they haven’t germinated.

Narrative:
This morning when Jeremy took care of the greenhab (I was in EVA), it
was really hot. We had difficulties to monitor the heat of the hab in
the morning : the fan cooled too much the greenhab.
The door was opened from 0940 to 1630 ; the fan from 1100 to 1130.
I replanted some radishes.

Harvest: None.

Support/supplies needed: None.

4) 18:30 PM 21.6° C / 46 %

Changes to crops: I replanted some carrots, and a read leaf lettuce. I pulled out flowering greens.
Spinach and mustard, in the pots, are sprouting. Peas in the shelf still look bad (quite yellow) even with the daily use of Miracle Gro.

Narrative:
This morning I replanted some carrots from the blue gardener to pots, so they have more place to grow. A lot of carrots needs to be replanted, the blue gardener is quite full. I will do it in the next days. I also replanted a lettuce.
This afternoon I pulled up the flowering carrots and radishes. Total biomass weight : 22 g of carrots and 17 g of radishes.

To monitor the heat in the hab, I opened the door at 0900, and closed it at 1630.
At 1100 the heat increased (28°C), so I started the fan (from 1100 to 1130 and then from 1430 to 1500) to cool down the greenhab. It worked well, since the heat in the afternoon didn’t reached more than 26°C.

As asked, I changed the hours of supplemental light : the light is now on from 0500 to 0730, and from 1730 to 2200. So we will have 7 hours of supplemental light tomorrow. Tell me if it is too much !

I harvested lots of basil, parsley, and sage for a homemade pizza, by our chief Aurélien !

Harvest: 11.2 g basil, 3.0 g of lemon basil, 10.4 g of parsley and 1.4 g of sage. 39 g of Biomass (flowering plants).

Support/supplies needed: None.

Changes to crops: I planted 8 pots of radish, as part of my plant experiment. I put them in a shelf and moved some tomatoes plant to the other shelf.

Narrative: Yesterday night, the blue tank was refill so we have a full water tank for the greenhab.
In the morning I changed the yellow fly papers.

This afternoon, I started the installation of my plant experiment. I planted 8 pots of radish (Raphanus Sativus), following my protocol. I tried the UV lamp for the experiment, but it doesn’t work. We tried to fix it at the RAM, but it seems that the fact that the frequency used for electricity is deferent from Europe makes it impossible to work. Thus the base we have needs to be changed. I think our UV bulb works properly.

As yesterday, I opened the door from 1200 to 1700 to cool down the greenhab.
7.0g of basil and 1.1g of parsley were harvested for soup.

Harvest: 7.0 g basil and 1.1 g of parsley.

Support/supplies needed: A UV lamp, or a base for the UV bulb we have.

Narrative: The door was opened from 1200 to 1700 to cool down the
greenhab, since the temperature reached 33°C.
After our formation with Atila, and with his agreement, we decided to
move the grow tent from the science dome to the greenhab, so I could
start my plant experiment tomorrow (study of the influence of music,
to improve radish defence mechanism to radiation).
A plant stake was added for the chives.
The blue tank wasn’t fil today, it will be tomorrow.
7.0g of basil were harvested for soup.

Harvest: 7.0 g basil

Narrative: At 0940 hours, the door to the GreenHab was opened to allow ambient airflow and was closed at 1600 hours. The sugar snap peas are continuing to improve and the yellow coloration present in the tomatoes continues to decrease. 2.5 g of sage was harvested for lunch. The blue tank will be filled tomorrow for the new crew’s use. The red romaine lettuce samples do not have red coloration which may be a sign of continued stress and should be monitored.

Thank you for the support and best of luck to the new crew.

Harvest: 2.5 g sage

Changes to crops: None.

Narrative: The A. thaliana experiments were concluded today. A full summary of the experiments is available in mission summary. Two particular simulants stood as the most successful. Approximately 500 mL of leftover Hoagland’s #2 hydroponic nutrient solution was used on the mystery greens to help in their seedling phase as well as on some of the tomato plants.

The door to the GreenHab was opened to allow for ambient airflow at 1110 hours and then closed at 1200 due to a temperature drop. The door was opened again at 1500 hours because the temperature had spiked due to the intensified sunlight reflecting off of the snow. The door was closed again at 1600 hours for the remainder of the day.

Harvest: None

Support/supplies needed: None.

4) 18:15 PM 19.4° C / 38 %

Changes to crops: None.

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.

Changes to crops: None.

Narrative: The nutrient supplementation in regolith experiments are still ongoing. However, due to mishaps in shipping, chlorophyll analysis may not be possible since the methanol has not arrived to the Hab (an organic solvent to help extract chlorophyll from the biomass). Consequently, these experiments may have to end without further analysis and they will be repeated upon return to Florida Institute of Technology using the same regolith samples. These experiments performed at the Hab do nevertheless represent the baseline tests astronauts will have to perform to determine the viability of substrates to support plant growth.

The nutrient deficiency observed in the tomato plants appear to be improving, since the yellow coloration is decreasing. The “Mystery Greens” from the spilled seed bank have sprouted and appear to be healthy, with two apparent variants of seedlings. Tomorrow, we will perform some additional grooming of dead biomass from several of the unhealthy plants to stimulate growth as well as contribute to our ISRU cellulosic ethanol study. Similar to yesterday, the door remained closed for most of the day due to the low ambient temperatures and overcast weather. However, at 1200 hours, the door was opened to allow for ambient airflow and closed at 1340 hours due to the drop in temperature.

Harvest: None.

Support/supplies needed: None.
