Greenhab Report – February 22nd

Crew 222 GreenHab Report – 19/02/2020

GreenHab Officer: Bleuenn ROIRON

Environmental control: Ambient

Average temperatures: 22°C

Hours of supplemental light: NA

Daily water usage for crops: 10 gallons

Daily water usage for research and/or other purposes: 0 Liters

Water in blue Tank: 89 gallons

Time(s) of watering crops: 2

Changes to crops: NA

Narrative: Today after watering the plants, I exposed watercress in gelatin to UV or/and notes of music that we had prepared before the mission.

Today was not so sunny so I didn’t have to open the door. I watered the plants again tonight.

Harvest: NA

Support/supplies needed: Water flow rate seems to be less powerful than at the beginning so it seems that I won’t be able to use the first tap in a few days I guess.

EVA Report – February 22nd

Crew 222 EVA Report 22-02-2020
EVA # 7
Author: Benjamin Auzou (CO)

Purpose of EVA: Replacement of the battery of MegaAres. The goal is to have a full battery before the rain episode so that the experiment can stay alive, even if no EVA is possible due to the rain or the mud on Sunday.

Start time: 9:31pm
End time: 10:04pm

Narrative: Everything went just fine. We rapidly changed the battery and assure the waterproofness of the experiment.

Destination: Experiments Site.
Coordinates (use UTM NAD27 CONUS): 12S 0518494-4250679
Participants: Benjamin Auzou (CO, EVA Leader), Marie Bochard (Journalist)
Road(s) and routes per MDRS Map: Entrance road – Cow Dung Road
Mode of travel: Rover – Curiosity

Title: Rainy day

In the prevision of rain, Benjamin and I went on EVA this morning to change the MegaARES’ battery in the hope that it will last for two days. We were very efficient, and after only 30 minutes we were back in the Hab.

Bleuenn took the time today to start her experiment “music for plants”,
in continuation of a similar experiment the crew 206 did last year. The
goal is to study the influence of music on plants’ ability to resist UV
radiation. This radiation will be very problematic on Mars if the
habitats are on the surface of the planet, hence the need to find ways
to protect or enhance the plants’ resistance.

Special sounds can inhibit genes that code for UV protection, hence the music (of course, it is a series of notes, not actual songs!). In 50 Petri dishes, she planted more than 500 watercress seeds, a plant that resembles salad.

Crew 223 will continue the experiment, so we are hoping to see promising results!

As the weather forecasted, this afternoon it began to rain. Thankfully,
it won’t rain on Mars…

We all kept quiet during the relaxation session, and we heard nothing
but the sound of raindrops falling on the roof. For those of us who live
in the city, it never gets this quiet and peaceful. We really feel cut
off from civilization, and it’s a great feeling. Not having to worry
about looking at our phones for messages or news is relaxing. We only have to communicate between ourselves, and speaking face to face is much nicer than waiting alone behind a phone.

Today my inspiration goes towards poetry. Rain is very poetic, and I
wanted to transmit that through Haikus. Haikus are Japanese poems
written with a simple rule for the number of syllables in each verse: 5
– 7 – 5.

Raindrops fall in peace
Nature always has her way
Keeping us quiet

Breathing in and out
Looking out the small window
Red sand in the rain

Standing in the rain
Nothing matters like you do
Alone with your thoughts

Summary Title: Safe in the Hab
Author’s name: Benjamin Auzou

Mission Status: Experiments outside safe and science inside running

Sol Activity Summary:

In the morning, we prepared the short EVA, whose goal was to replace the battery of MegaAres.

The afternoon was dedicated to activities and experiments in the MDRS Campus.

Look Ahead Plan:

Tomorrow, we will stay in the Hab because of the rain and the mud. This Sunday was supposed to be a day-off in our planning, so we will spend less time on experiments, but because today was very calm, without a long EVA, we will continue some experiments work.

Anomalies in work: Internet issues since 10 am
Weather: cloudy, started raining at 5 pm
Crew Physical Status: one crewmember suffers from a shoulder pain
EVA: MegaAres battery replacement

Reports to be filed: Journalist report, Operations Report, GreenHab Report, Astronomy Report, EVA Report
Support Requested: Water in the GreenHab Tank
