Green Hab Report – Sol 5
Report written by: Victoria DA-POIAN (Crew Biologist)
Date : 02/17/2017
Functionality: The heater in the green hab is working well. Today was a very cloudy and windy day ! As I was in EVA this morning, Louis Maller has checked the temperature in the GreenHab this morning. It was around 24 Celsius degrees around 9:40 AM while the temperature in the tunnel was around 10.4 Celsius degrees. He switched on the cooler (on step 1) and the GreenHab temperature was 20 Celsius degrees at 4:00PM while it was 14 Celsius degrees in the tunnel. I switched the cooler off. Louis Maller watered the seedlings this morning, and I did this afternoon too.
Status: The existing seedlings in the green hab are continuing to grow well. There are spinach, lettuce, radish, and beans growing very well in the small pots.
The lettuces are growing well too.
The Vegidair has been installed yesterday and is functionning well.
Planned activity: I have checked my new plants (planted yesterday) , the ones I want to compare with the ones I have in the Vegidair.

Journalist report, 02/17/17 – Sol 5: Seismometer, storm and fresh bread.
Today was my first day following an EVA from the hab. Moreover, I was its habcom. After breakfast, I was in charge of checking everyone’s radio, backpack, timing the pressurisation, and giving tasks to the crew members outside during the check-ups at the beginning of the EVA. Then I was following their actions by radio when they were in range.
Today’s EVA included Arthur, as leader, Mouâdh, Victoria, and Simon, who had taken the camera, so that today’s pictures of the outside would not be mine today. Their first objective was to install the seismometer where we planned to two days ago. It went well and was finished quickly. The balloon remained in the hab, because of the wind blowing too hard. That is why, after half of the EVA, the team started to explore the surroundings, went up to hab ridge road, then back, training on how to use the map in situation.
At the same time, in the hab, I was busy working on interviews for French medias, Xavier was working on the energy supply of the station, and Louis was busy with the EMUI. The afternoon started quietly, with almost everybody taking a nap, but after a couple of hours, wind started to blow very strongly. The whole station became very noisy, parts moving everywhere, we had the strange feeling that we could take off at any minute… Our brand-new wall was moving dangerously, but went through it. Xavier and Louis had to go out on an “emergency EVA” to check if nothing was damaged, and to pick up stuff that flew away.
For dinner, Simon had baked fresh bread for us. He now masters the art of using the bread machine well. It might seem simple but it is the only way for us to get fresh food. And for French people, being able to eat fresh bread even if it isn’t baguette is priceless…

We could deploy the seismometer this morning, during the EVA. It was quite hard to do, with the gloves, especially to put the seismometer correctly. It was nevertheless a success. We decided to put the Stanéo digitizer in a box in order to protect it, and we covered it with a piece of plastic. We have then tried to immobilize everything by putting stones here and there.
The weather on the rest of the sol was worrying: there was a lot of wind (impossible thing on Mars because of the low pressure on its surface). I fear that the structure might crumble. Unfortunately, we’ll have to wait until tomorrow to check this out, during the next EVA.

We were first supposed to use the balloon during the EVA this morning. Unfortunately, the weather was not on our side. We still don’t have enough results to make any conclusions. We hope to use it again next week.
The crew engineer and I started working on our new project about emergency procedures. There are three main points in that study. First, we will study the emergency procedures observed during scuba diving. One of the big step in this study is the comparison between this sport’s dangers and EVA’s ones. Secondly, we will try to set up different emergency procedures depending on the issues and brief the rest of the crew about it. Finally, we will simulate unexpected health or material issues during EVAs and try to apply these procedures.

Sol 5: back to normal after yesterday’s festivities.
Mouâdh, Victoria, Simon and I went on EVA this morning to install the
seismometer in the hole we dug close to the Main Road, South of the
Hab. We had also planned to deploy the balloon for the second time,
but the wind was too strong. The exploration we did afterward led us
to the top of the Ridge, where we discovered a stunning panorama: in
front of us the red plain enclosed in mud hills, behind us the
colossal mesas of Skyline Ridge. Our hike offered us an unusual sight
on the MDRS from above. We should definitely come back up here on a
A very strong wind rose after lunch, blowing away all the outside
stuff that was not attached (typically: the unused cardboard we stored
yesterday). In order to avoid further mess and to take a look at the
potential damages around the station, Louis Maller and Xavier went out
for a short EVA. In the end, no hurt was noted on the different
facilities, but Louis and Xavier preventively fixed a water tank on
the rear of a rover. We were glad to see that our upgrade on the
tunnel stood still (we call it “The Wall”). This storm reminded us of
the non-realistic beginning of Andy Weir’s novel “The Martian”, with a
minor difference though: the terrestrial wind is strong enough to blow
away heavier things than sand… So better stay aware, even if this
situation is totally impossible under Mars thin atmosphere.
Otherwise, there is nothing to worry about. The crew stays in a good
mood, science goes on and we have plenty of food left (at least for
