Crew 222 EVA Report 19-02-2020
EVA # 3
Author: Bleuenn ROIRON (GHO)
Purpose of EVA: Change batteries of LOAC and MegaAres, and then first
exploration for the crew 222
Start time: 9:04 AM
End time: 11:07 AM
Narrative: First, we went out to check all the rovers and the water. We
moved then in teams of two to our experience site to change
batteries and check the data for the MegaAres. Everything went fine so
we moved to URC Northsite and arrived at 9:45 to start our exploration.
All of us were very excited for that. We walked for approximately one
hour bewteen URC Northsite and North Ridge. Landscapes were really
differents from those we are used to, especially because of colors, the
ground was red, beige and sometimes almost purple. We climbed a
small hill to have a large overview on what was around us and took a
break on it to really appreciate landscapes. Then we came back to the hab.
Before coming back in it, we had a small check on tunnels. We entered
the station again at 11:07 AM.

EVA # 2
Author: Nicolas Bourdeaud
Purpose of EVA: Install the electric field sensor (named MegaARES). Start time: 9:26am
End time: 11:01am
Narrative:
After the first steps on Mars for three of us, we checked all rovers status and the static tank level.
Then we decided to check the ATV’s batteries. Three of them started more or less easily. After 5 minutes, as we did not succeed in switching on the last one, I decided to give up, and to let this issue for the engineer’s EVA of tonight.
Then we moved to the place we needed to set the experiment, the same we chose yesterday, for the weather station and the LOAC.
One team began by changing the LOAC’s battery.
The installation of the MegaARES has been successfully carried out. We came back earlier than what we had planned.
Destination: plane area approximately 500m away from the Hab, along Cow Dung Road (same than yesterday)

Participants: Nicolas Bourdeaud (HSO), Benjamin Auzou (CO), Marie Bochard (Journalist), Eishi Kim (AST)
Road(s) and routes per MDRS Map: Cow Dung Road
Mode of travel: Driving (needed for material transport)

Narrative: Today, I watered plants after being the habcom of the second EVA. After the lunch, I went to take care of the spirulina and separated some plants( salad and carrots) to let them grow more. Then I helped Nina, our crew scientist, to plant in moss her seeds that we will next deplace in the
culture tower that was installed today in the science dome. I went finally in the evening to watered a second time the plants and took some sage for our meal.

Journalist Report – February 18th
Here is the report of the journalist who was in the EVA today !

Title: Head in the stars!
Today in EVA, we were tasked with setting up the experiment MegaARES, a giant aluminium sphere that measures the magnetic field of the planet. When we practiced putting it up before leaving, it did not take too long, but here it took us two whole hours! It’s hard to imagine how difficult it is moving in a spacesuit. Every small task becomes difficult. Just getting in the rover seat was tough, and trying to get back up after sitting down was even harder. This is in part due to the large backpack we have to carry around, since it is quite heavy and impairs our movements, and since this was our first EVA we kept bumping into each other lightly. Thankfully we quickly got the hang of it, and the suit no longer bothered us.
Upon our return, we could smell the delicious smell of a savory cake waiting for us. Martian food, when cooked to perfection, can rival with Earth cuisine! Especially when seasoned with GreenHab-grown greens that our GreenHab officer harvested yesterday.
Here, far from civilization, far from any man-made light, the night sky is beautiful. Today, Eishi showed us the pictures of a galaxy that he took last night. As the Astronomer, he has access to three telescopes here in the MDRS.
The first one is for finding objects in the night sky, such as galaxies and stars. It is fully automated and it can follow the objects that the Astronomer wishes to study during the night. It then activates the second telescope that takes astrophotography, and in the morning, the Astronomer has access to all the images taken by the telescope.
The third one is a manual solar telescope that is used to follow the Sun’s activity during the day. With it, we can see clearly the dark spots and solar eruptions. This will be crucial on Mars, because without a magnetic field all the radiation from the Sun directly hits the surface of the planet, and this can be fatal to Marsonauts who will live there. The Sun isn’t a still ball of plasma, it has phases where its activity increases or decreases, and following these cycles is important to ensure we can predict future activity and prevent any danger. Solar flares can be dangerous for the Earth too, as it interferes with electronic instruments! Even if it is millions of kilometers away, it has the power to make and destroy.

Summary Title: Get to know Mars better
Author’s name: Benjamin Auzou
Mission Status: Mission planning followed, experiments running Sol Activity Summary:
In the morning, the crew woke up with an other matinal workout session, that created muscle pains to some members. Then four crewmember went on EVA to install a field experiment next to the experiment installed yesterday.
At lunch, the crewmembers that stayed in the Hab prepared a salted cake and a delicious soup.
In the afternoon, crewmebers worked on their experiments in order to start getting results as soon as possible. Also we all passed a human factors experiment, directed by Eishi.
We finished the day with a relaxation session directed by our HSO, a full body scan. The reactions were very different between the members of the crew.
So we started to know Mars better with the experiments, but also by finding habits here.
Look Ahead Plan:
Tomorrow, an EVA team will make some maintenance work on the two experiments and continue with an exploration of the area north of the Hab. We hope to get the water monitoring working as soon as tomorrow evening.
Anomalies in work: none
Weather: some clouds but clear in general
Crew Physical Status: some muscle pains from sport sessions
EVA: MegaARES installation success, all members of the crew have performed one EVA now
Reports to be filed: Journalist report, GreenHab Report, Astronomy Report, EVA Report, EVA Request, HSO report
Support Requested: propane tank refilling, trashes in the engineering airlock

Crew 222 Science Report 17Feb2020
Author : Nina SEDBON
Title : Several experiments begin
In the Morning :
• LOAC and Weather Station: Put in place during the EVA. They were working just fine.
• For the LOAC the conditions were easy to obtain : stable floor, parallel to the floor for the wind captor.
• For the weather station : Girouette North orientated, three feet at a 90° angle from the ground for the whole to be very straight and vertical.
In the Afternoon:
• Aerospring : the conditions are very different in the GreenHab and in the Science Dome. We need more information to start building it because it will be very difficult to change its location once it is built. We only planted : Swiss chard, Radish, Spinach and Peas to transfer it in the vertical garden after it starts growing.
• MegaAres: Few tries in the Lower Deck to prepare the EVA for tomorrow.
• In the GreenHab : Start of the Spiruline experiment in the two aquariums.
• Backpack : Few operations in the RAM to connect the LCVG to the backpack.
• In the RAM : Fixing of the hygrometric captor for the Weather Station.
• Human Factors experiment called Foreign Languages at 16h45. It is organized with sessions of two people for 15 minutes each time. The first session is in Spanish. The two others are in English. It is a cooperation game with LEGO.
• Water Experiment: Few checks for the electrical setup. We hope to start the experiment tomorrow night. We will describe the set up once it is put in place.
Problems faced today concerning the environment of the experiments: The lack of screen for the water experiment was unexpected. A computer has to be
used to replace it.
The lack of « oscillator » for the MegaAres. It is thus complicated to test it before the EVA.
