Sol 5 – 27/11/2017

Green Hab Officer Jordan Bowden

Average temperature: 28.5 C in Greenhouse / 10 C Outside

Changes to crops:  Everything is growing well.

Daily water usage for crops: 3 Gallons

Time(s) of watering for crops:  11:00, 14:30
Daily watering and amount of water used:  2 gallons used at 11:30, 1 gallon used at 16:30. 3 gallons total.

Narrative: Greetings CapCom,

Unfortunately my time on Mars is coming to a close, and as such, today was my last full day taking care of the Green Hab. Things have been coming along steadily in the space, and I’m happy to report that all of the plants seem healthier and bigger than when I arrived; as a non-expert gardner, this is the best I could really hope for.

Today we went on our final EVA: the sky was cloudy and the winds very strong. This weather was totally different than the rest of our time here on Mars: on other EVAs, the sun was so strong that we were sweating in spite of the actual outside temperature. Overall, it was wonderful to see the scenery and get some good work done outside the Hab.

Lastly, I wanted to emphasize how much I have enjoyed our time here, and how transformative the impact this time has had been on our work and research. I’m amazed by this space and the community that keeps it going, and I can’t say enough how grateful I am for this experience.

Let me know if you need any electronics designed or parts 3D printed for the upcoming Aquaponics system in the Green Hab, I could send them out to Mars if it’s feasible.

You’re the best, CapCom. Thanks for your hard work.

Signing off,

Jordan Bowden
Green Hab Officer

Sol 4 – 26/11/2017

Green Hab Officer Jordan Bowden

Average temperature: 28.5 C in Greenhouse / 8.5 C Outside

Changes to crops:  Everything is growing well.

Daily water usage for crops: 4 Gallons

Time(s) of watering for crops:  11:00, 17:00

Daily watering and amount of water used:  2 gallons used at 11:00, 2 gallon used at 17:00. 4 gallons total.

Narrative: Greetings CapCom,

Everything was growing well in the Green Hab today – it’s amazing to see the growth since Sol 1. Grow lights are operational. Nothing significant to report.

We had a great EVA today. Progress also continued on our 3D Printing projects – I came close to completing my design for a Neonatal Aspirator device.

All the best,

Jordan Bowden
Green Hab Officer

Sol 3 – 25/11/2017

Green Hab Officer Jordan Bowden

Average temperature: 23 C in Greenhouse / 9.6 C Outside

Time	10:00	–	17:00	19:00
Temperature inside (°C)	31 C	–	20 C	17 C
Temperature outside (°C)	8C	–	12 C	6 C

Time(s) of watering for crops: 10:00, 17:00

Daily watering and amount of water used: 2 gallons used at morning watering, 1 gallon used at 17:00. 3 gallons total.

Narrative: Greetings CapCom,

For the most part, everything was growing well in the Green Hab today. One of the tomato plants leaves started to brown, in a region where it was wilted on Sol 1; I will monitor it closely. Grow lights are operational. Not much else to report.

Sol 2 – 24/11/2017

Green Hab Officer Jordan Bowden

Average temperature: 27.3 C in Greenhouse / 9.6 C Outside

Changes to crops:  Everything is growing well. The adult tomato plants are no longer wilted.

Daily water usage for crops: 4 Gallons

Time(s) of watering for crops:  11:00, 16:30

Daily watering and amount of water used:   2 gallons used at each watering, 4 gallons total.

Narrative: Greetings CapCom, things are going well in the Green Hab on Sol 2!

I noticed that it was very hot in the Green Hab when I checked it at 11:00 this morning (46C); I will be sure to open the ventilation tomorrow by 8AM. Otherwise, all crops are healthyl.

I installed lighting timer in the Green Hab today, so the grow lights are now online from 17:00-21:00.

Not much else to report. Outside my duties as Green Hab Officer, I set up our 3D printer server, designed two 3D printable medical devices, and explored Lith Canyon during our EVA.

All the best,

Jordan Bowden
