Narrative:

We began the SEEDS OF MARS experiment with Erin. This project represents an educational experiment designed for school children. The objective is to engage two classes in our mission, fostering awareness of space exploration and cultivating their scientific processes. Their task is to experiment with the scientific premise of the movie "The Martian," specifically the cultivation of potatoes in Martian soil. The experiment will involve a test group planted in analog Mars soil and a control group (in potting soil), both cultivated under precisely identical conditions (water, luminosity…). Today, we planted cress in two different pots following the school children protocol. We setup an environmental sensor (temperature, humidity, luminosity) to monitor, we also setup a phone to take a time-lapse during the entire mission.

Harvest: (include which crop and mass in grams) : 333g of tomatoes

Support/supplies needed: None

At a few different spots, there is some sort of grass : “Grass MR green”, “Grass storm”, “Grass Spray”. Do you have any idea of what this is?

I just feel it is using space for nothing. However, I’m asking because it may be here to help other plants grow better. But some of them are in individual pots.. this looks strange.

Narrative:

Sol 12 started with a sleepy early morning and a bittersweet feeling. It’s the last day here at MDRS for our crew and I’m already missing the plants and the GreenHab. I must say that I learned a lot practicing simulation. I realized it’s not really hard to live using less resources and staying in a small space collaborating with crew mates, being disciplined. I have learned that space is just a state of mind. If all the humans practiced living the same way outside of simulation the same way we live in, earth would be a better place than how it is now, and going to mars is a different story. We are breaking the sim by mid-day and I will continue to be the same human as I am now than who I was when I entered MDRS , only the spirit for going to mars will keep accelerating . I cleaned up the GreenHab with some help from Bharti, our crew geologist and watered the plants. Emptied the trash can and went to hab. Best wishes to all the GreenHab officers and their mission.

Water level was 114.6 gallons on 02-16-2024 according to last crew 292’s report. Am I supposed to deduce the water level from that? If so, can you communicate the water used on 02-17-2024?

Time(s) of watering for crops: 1pm, 5pm

Narrative:

I used the spray both time I watered the crops

I drew a complete map of the greenhead to identify the different crops and changes needed for the next few weeks.

Harvest: None (include which crop and mass in grams)

Support/supplies needed:

I have spotted one or two grasshoppers. Do you consider it an issue or can I let them enjoy the greenHab?

Narrative:

Today was the day for my experiment pots to come out from the growth tent because they seemed all sprouted out. All the four pots were placed in four different spots (Pot 1 : Hab, Pot 2: Green Hab, Pot 3: lower deck of Hab, Pot 4: Science dorm). I will be watering them daily and checking temperatures for all the pots and the progress for their growth. There is not much time left to obtain a good amount of data but I would be really grateful and happy if the next GreenHab officer will continue this experiment.

The crops were watered in the morning and in the evening as well because some of the crops on the small table looked withered. I am planning to put a shade in the GreenHab if that is possible as the sunlight seemed harsh during the afternoon at some point in the GreenHab. My pan experiment is going well in both the science dorm (growth tent) and the GreenHab. We had a harvest of a few herbs and greens for dinner. We are going to make nice pizza.

Harvest:

Lettuce : 4g

Tomatoes: 40g

Kale: 29g

Changes to crops: More ripe tomatoes

Narrative:

Today I watered the plants two times again, morning and evening evenly i e 4 gallons in the morning, 4 in the evening. I also used mist spray in the afternoon on all the crops. Temperature in the afternoon went up to 100 F. I moved the withered plants receiving too much sunlight to a different place where the tomatoes are. I see a lot of tomatoes in their ripening process. They shall be big and ready to eat for the next crew.

It was also my second last EVA and I already feel sad about leaving MDRS as all of my study and experiment needs some more time. But I think I can figure it out later so I am just focused on staying in the moment. I am also hoping the GreenHab officer of the next crew to continue my experiment. Today we went to Candor Chasma. We climbed down in the canyon and found lots of Gypsum and Cherts. We also found mountain lion’s caves. I really enjoyed the long off-roading on the rover. In the evening I sat with Daniel and learned how to make DNA so later I can use the technique to extract DNA from plants for my research in maintaining or building a GreenHab back in India. Both of my experiments are going well. The pots are science dorm , Hab , GreenHab and lower deck of Hab are pretty much the same. I am afraid the pot on the lower deck might die and I feel bad about that pot. But I’m hoping to get something out of my experiment to validate my research. Happy Valentine’s Day!!

Narrative:

Today is the last day for the crew in sim. We are going to break sim tomorrow. I started my sol day by performing my usual duties. Went on my last EVA to put back the rocks Clare got from early morning around 9:30. I am happy that my experimental pots at different locations are doing well. The newly sprouted seeds of radish in the big blue tank look all green. I am planning to clean the GreenHab tomorrow. Aditya, our astronomer, helped me harvest veggies for Pasta. We picked almost all the good grown green leaves, radishes and tomatoes. There are more cherry orange tomatoes all ready to become red for the next crew. Today will be the last day I will conduct my Pan experiment for evapotranspiration measurement.
