Summary Title: The wind is back

Mission Status: Going great

Sol Activity Summary:
After an upper body physical session and enjoying a delicious pancakey breakfast, the Crew 330 is fully back to work today. This morning we did an important EVA that could contribute to two experiments simultaneously, by having four crew members on the field for the first time. The rest of the crew continued to monitor the station and make progress with our indoor experiments. After another great meal at noon, thanks to our recent resupply, we continued in the afternoon with intense activity. Adèle and Adrien kept progressing on the editing of the mid-mission video, Célia and Félix could start their Lab’Ex observations, Julien continued to conduct the NeuroErgo experiment and Lou started the Photogrammetry map from the morning EVA. Meanwhile Gaspard conducted mid-mission interviews with each member of the team, to gather each one’s feelings about the first half of the mission, and the expectations for the second one. We feel once again the ominous presence of the strong winds, monitoring the integrity of the station and hoping for the best data for our atmospheric experiments.

Look Ahead Plan:
We are looking to keep working on the Photogrammetry and Stratigraphy experiments with more EVAs in the week, and we keep on conducting all experiments in the station.

Summary Title: Calm day on Mars

Mission Status: The routine is there, everything flows smoothly

Sol Activity Summary:
As we are leaving the mid-point of our mission behind us, we feel more than ever like we have been on Mars for a very long time. While we are still in great shape and eager to continue to get great results during the mission, the days are starting to look very similar each morning. We are encountering less and less issues in the station, and the atmosphere feels calmer now, everyone found their rhythm and accomplishes their tasks with ease. We did Yoga in the morning, activating our bodies and resting our mind at the same time.
We had a small worry about a gas leak today in the Hab, but after checking with the station’s sensors, it seems to have been a false alarm, only the smelling product is leaking in the lower Hab from time to time.
Today’s EVA got farther than we ever did during this mission, discovering once again new landscapes to wonder about.
The whole crew keeps working on our mid-mission video in parallel to our usual other activities.

Look Ahead Plan:
We are looking to keep working on the Photogrammetry and Stratigraphy experiments with more EVAs in the week, and we keep on conducting all experiments in the station.

Summary Title: All kind of successes

Mission Status: Going great

Sol Activity Summary:
Today was a great day, with every experiment going great. We got up a bit later than usual in the morning instead of having our usual physical activity session, to rest our bodies a bit. The orienteering EVA for the second session of the Photogrammetry experiment was a success, and we gathered interesting data. In the station, we made progress again with everything else. The mid-mission video is finalized and should be published on our social medias shortly. The Geol’Ex instrument is getting calibrated to continue the Lab’Ex experiment, and our human factors ones continue to gather data steadily. The atmospheric experiments survived the strong winds of the past few days as well. The crew feel both efficient and relaxed in the station.

Look Ahead Plan:
We are looking to keep working on the Photogrammetry and Stratigraphy experiments with two more EVAs in the week, and we keep on conducting all experiments in the station.

Summary Title: Another good sol on Mars

Mission Status: Going great, two thirds done !

Sol Activity Summary:
Today was another good and calm sol. We didn’t encounter any new issue with our experiments or the station itself.
In the night, our ground team published our mid-mission video, and we are very proud of the result. We hope that it shows in a beautiful way all the work we have been doing in the station for the past two weeks !
In the morning, we worked our lower body with a physical session prepared by Adèle and Julien together. This time, the EVA team used a 3D map for orienteering, and clearly beat the performance of the 2D team, showing the usefulness of Photogrammetry for exploration. The rest of the crew kept working on other experiments in the station, and took time to rest a bit. Even though the mission is going better than ever, we are still feeling fatigue from the isolation and confinement, and we can feel it more as the week gets closer to its end (and the so awaited rest day !).
As today was quite cloudy, we tried to minimize our electrical consumption. Usually a resource we have in excess in the day thanks to our huge solar panels, like every other one on Mars we had to think about every usage and how necessary it was.

Look Ahead Plan:
As we approach the last leg of our mission, we are beginning to plan the conclusion for everything we have set up in the station, both for our living quarters and for our experiments. We are looking forward to our last rest day, to fully recharge our batteries and finalize everything with renewed motivation.

Summary Title: A successful third week

Mission Status: Going great

Sol Activity Summary:
Today was the last (working) day of our third week of mission. During my first rotation, with the Crew 206, this would mean the end of the mission. A longer mission is definitely more challenging, both physically and mentally, but it also offers so much more time to do science and gather meaningful data ! We still have a few experiments to wrap up before we leave in 6 working days, and we are motivated to do our maximum to get the best results possible.
This morning’s EVA went great, the team was once again mesmerized by the landscape they discovered during their exploration West of Tharsis Montes, and brought back beautiful photos. Exploring is one of the main reasons to send humans to Mars, and it feels nice to simply discover the surface rather than conduct pre-planned experiments.
In the station, we kept maintaining everything in good order, by cleaning the Hab a bit and emptying the toilets tank. Adèle had prepared sessions to learn new tools about emotions and communication with others and the whole crew listened (and participated !) with great attention.
Tonight we have a lot of "surprises", activities prepared individually by each one to entertain the rest of the crew, it will be a lot of fun ! We can enjoy our evening because tomorrow is rest day ! We will be able to sleep as long as we want in the morning.

Look Ahead Plan:
Tomorrow is our rest day, we will rest both our bodies and our minds, and do activities together to keep the team spirit high.

Summary Title: Last rest day

Mission Status: Going great

Sol Activity Summary:
Today was our day off from experiments and EVAs. However, the station never sleeps and we conducted some maintenance of the habitat in collaboration with mission support. We used the rest of our time to rest, and do all kinds of relaxing activities. Félix and Célia worked all day in secret to prepare some big surprise. We won’t have the time to discover what it is today, but they expect it to be ready for tomorrow. The greenhab had some trouble cooling down today, so Félix had to troubleshoot that and extensively water the plants.

Look Ahead Plan: Tomorrow we start our fourth and last week in the MDRS. While we are beginning to miss some of our lives on Earth, we are excited to wrap up all of our experiments, and we want to make the most of the remaining days.

Anomalies in work:
– Issue between the GreenHab controls and its fan, might be solved but we will monitor it closely

Summary Title: The start of the end

Mission Status: Going great

Sol Activity Summary:
Today was an intense day, full of renewed energy. The combination of the rest day and the end of the mission approached motivated us throughout the whole sol.
We had a shorter night, because of the switch to DST, and decided to sleep just a bit more by skipping the physical activity session in the morning. We ate our last batch of pancakes for breakfast (we may have overused them a bit for reassurance during the past week) and started a productive sol.

Today was the Day of Women’s rights on Earth and Adèle, Célia and Lou filmed some videos to encourage women in France to achieve their dreams. They also did our furthest EVA so far, which was a success (despite not seeing any sign of past life on Mars). Right after lunch, we played a real life "Among Us" game in the station, prepared by Célia, Adèle and Félix yesterday.

It was a lot of fun before getting back to our usual activities. Adrien filmed a lot for his documentary, and we continued to gather data from our human factors experiments.

Look Ahead Plan: We will keep on conducting our experiments, and start to do the assessment of our stay in the station.

Anomalies in work: The Home Assistant dashboard has lost connection to the batteries and the generator. The power system otherwise seems fine.

Summary Title: A little zoom on Mellow Mushrooms
Mission Status: Going great

Sol Activity Summary: This morning, four of us went on an EVA to Marble Ritual and then to Mellow Mushrooms. At Marble Ritual we did the usual maintenance of atmospheric instruments. After this very quick stop, we headed to Mellow Mushrooms to find an interessant outcrop. It was difficult to choose but we finally chose a typical one : a Morrison Formation. Julien and Lou continued to assemble the SupaeroMoon rover. Célia and Félix made some progress regarding the Geol’Ex experiment they will use to analyze the sample. Indeed, during the EVA they took 8 samples of rocks at different locations of the outcrop. The commander started the Mission Summary this afternoon.

Look Ahead Plan: We will keep on conducting our experiments, and start to do the assessment of our stay in the station.

Summary Title: Getting ready for Earth

Mission Status: Going great, 2 days left
Sol Activity Summary: Once again today we had a lot of work to do. In the morning we had a specially intense physical activity session. It could be very hard to return to Earth’s gravity after a few years between weightlessness and Mars’s lighter gravity, so astronauts should work harder on the way back to rebuild muscle mass.

The rest of the morning saw the crew working hard on their remaining tasks, crucially we had to finish building the SupaeroMoon rover for this afternoon’s EVA. Because we had to 3D print every piece of the rover, the timing to test it in the desert is very close.
For lunch, we prepared quite an inventive meal with the few remaining supplies for our mission. Even with reduced ingredients we manage to eat plenty and tasty food, which feels rewarding each time!

In the afternoon, the EVA team used the RAM as a temporary depressurized module, to test and troubleshoot the SupaeroMoon rover. The rover didn’t meet its performance objective, but the EVA was a success from our point of view, as we could conduct the tests without any issue on our end.

We kept gathering data for the Orbital Architecture and NeuroErgo experiment and will keep doing so until the end of the mission. We have to anticipate the end of the mission, and put back the station in order for the next crew so we have to find the perfect trade-off between maximizing science and sleeping the next few nights.

Finally, the crew journalist wants to shoot as many scenes as possible before leaving the station, as he doesn’t want to miss any single part of the mission for his upcoming documentary.

We kept making progress on the assessment of our entire mission, taking surveys and writing reports on everything we did during this last month.

Look Ahead Plan: Tomorrow will be our last full sol in the MDRS. We will dedicate every bit of our energy to the final tasks ahead of us. We will conduct our last EVA to bring back the atmospheric experiments to be packed up on our departure.
