"What the hell on Earth is going on?”

On their way to White Rock Canyon, the EVA team stumbled upon a Coke bottle. In the middle of a Martian hiking, Norbert, Jérémy, Aurélien, and Cerise are sent back on Earth.

The planet is endangered, with limited resources, and we continue to pollute and threaten her, even if we are all aware of the danger. Here in the MDRS, we are monitoring our water consumption, our trashes and our energy consumption. For now 4 days we have been following a simple, but healthy and sustainable way of life. We realized that our habits are greedy on resources, on water, on energy. And that it is not so complicated to change and adopt better ones. Even if we want to send humans to Mars, or to the Moon, Earth is and will stay our cradle and our home and we all have the duty to protect her!

Countries have the duty to adopt laws to promote ecology and sustainable development, companies have the duty to use wisely their energies and resources, and at our scale with have the duty to adopt a sustainable way of life. We all have this duty for us, for our children and for all humanity.

In the same time in the Hab, Gaspard and I choose to prepare a surprise olive bread for the crew’s lunch. Unfortunately, that first try was very different from the texture of French baguettes, but everybody loved the taste and it was a huge pleasure to feel a little bit like in France.

After lunch, everybody in the Hab chose to take a nap before the beginning of the human factors experiments. Sadly, both versions of TELEOP experiment failed today: the little rover faced connection issues and the computer of the digital version ran out of battery, with a broken charger. This experiment matters a lot for all of us, especially for Jérémy and the rest of the afternoon was very difficult for us.

The good news of the day came from Cerise’s water monitoring. Yesterday, the results seemed threatening. After an exchange with the research team, the comparison database that she was using was the one dedicated to space, and to Thomas Pesquet’s Aquapad experiment on the ISS. With the correct database, the water quality is not perfect, but safe to drink and not infected.

After the disappointment of the afternoon, we all need a distraction. For that, Norbert brought us some fresh carrots from the Green-Hab for the dinner and we decided to watch an episode of Nat Geo’s Mars TV show.

EVA Report – February 28th

Crew 206 EVA Report 28-Feb-2019
EVA #4

Author: Norbert Pouzin

Purpose of EVA: The EVA has two purposes:

– the first one is scientific. It is to make sure that the deployment
of the LOAC and the weather station is fine. Since the snow has melted, we have to re-calibrate the tripod of the weather station. Also, the batteries of the LOAC have to be changed.

– the second purpose of the EVA is the exploration for the other half of the crew who didn’t perform it today. We will go to White Rock Canyon and explore this area. We will park the rovers on the road 1101, at the closest point from the White Rock Canyon, and then walk to the canyon. As the distance between the MDRS and White Rock Canyon is a little bit smaller than the one we did today going to The Moon, the batteries of the rover might not be a problem (34% battery left for Opportunity, 65% for Curiosity).

However, if it appears that the batteries aren’t strong enough to bring us there, we will explore Kissing Camel Ridge West, parking the rovers on Cow Dung Road 0110, near Robert’s Rock Garden. Like today, we prefer being four for this EVA, so that two of us can work on the tripod and the others on the LOAC and we can be two on
each rover, which is safer than being alone.

Start time: 9:00 am

End time: 11:26 am

Narrative: Today, we went pretty fast on our EVA preparation, so we left the hab at 0900, instead of 0915, as it was planned. After the usual checks (Water tank for Team Red, composed of Aurélien and Jeremy, and rovers states for Team Blue, composed of Cerise and me), we went to the localization of the LOAC and the weather station.

We arrived there at 0915. While Team Red changed the batteries of th LOAC, Team Blue measured the inclination of the weather station, as the melting snow might have moved the tripod. Indeed, the angle had moved a little, so we tried to fix it by turning the screw of the tripod. We left the area of the LOAC at 0931, heading into White Rock Canyon with our rovers, taking care of the batteries, like yesterday. It worked pretty well, since we parked at 0952 on the road near the Canyon, with 90% batteries for Curiosity, and 85% for Opportunity!
We started the exploration, following our scout Jeremy. We went inside the canyon, and then hiked to go above it.

The soil wasn’t as muddy as it was yesterday, so we could easily walk. At 1058 our walk was over, and we came back with our rovers. We arrived at the station at 1120, with more than 60% of batteries on both rovers.

Destination: LOAC and Weather Station location, Road 1101, White Rock Canyon

Coordinates: 518500/425700 (LOAC and Weather Station), 520250/4247600 (White Rock Canyon)

EVA Participants: Norbert Pouzin (GHO, EVA leader), Aurélien Mure (XO), Jeremy Auclair (CMD), Cerise Cuny (HSO).

Summary Title: French bread in the Station

Author: Jeremy Auclair

Mission Status: All nominal

Sol Activity Summary: Muscle aches from the morning workout have finally passed, it feels pretty good. Our sleep patterns are getting better. This morning’s EVA’s purpose was to change the LOAC battery (which went perfectly) and to explore White Rock Canyon. The rovers performed better than yesterday, we managed to arrive at White Rock Canyon with more than 85% of charge. The exploration lasted for about 1h30, the view was exceptional and we took great pictures. The mud is still bothering, but nothing that we can’t overcome. We arrived at the Hab a little tired. For lunch, we ate pasta and we cooked our first bread!

This afternoon I worked on TELEOP again, but I encountered new issues: the computer charger is broken, and we haven’t found an equivalent one. I managed to connect the physical rover to my computer by there is still connection issues. To sum up: both TELEOP versions are currently not working. It was a hard day for me, but the rest of the crew had more luck. Cerise got a response from the BioMérieux lab: our water is not infected (we feared there were some bacteria), it’s safe to drink, but it’s not as clean as tap water. We are still experiencing internet issues, it seems to be coming from the router (I couldn’t connect before 07:08 pm).

Look ahead plan: Tomorrow will be a regular day, we will try to fix some issues on our experiments. The crew is impatient for Sol 6; they will try their space suit for the first time in real conditions.

Anomalies in work: None

Weather: Sunny in the morning, partly cloudy in the afternoon

Crew physical status: Fine

EVA: White Rock Canyon

Reports to be filed: GreenHab, Journalist, Operation, EVA Report, EVA Request
