Sol 16 – An extraordinary routine

“They began to plan people’s lives and libraries; they began to instruct and push about the very people who had come to Mars to get away from being instructed and ruled and pushed about.”

– Chapter 16 of The Martian Chronicles by Ray Bradbury

When we awoke and found that the Martian desert was once again covered in snow, and having heard the winds howl in the middle of the night, our first reflex was to reach for the binoculars, strategically placed on the main windowsill, from which we could see the atmospheric instruments. We breathed: rocks, tensors, and metal rods hammered into the ground had kept everything upright! There was no need for an emergency EVA.

This morning, we decided to change it up a bit: instead of our usual workout session prepared by Corentin, we relaxed and stretched to the sound of a yoga session brought by Jérémy. Feeling a little bit too relaxed and sleepy afterwards, we put on some music, did some push-ups and just goofed around the Hab. It’s these sparse moments of unbridled fun and laughs that convince me our crew works: no amount of hard work or accumulated stress can prevent us from having a good time all together. In the past few days, the song “Cheerleader” by OMI started coming back more and more often during our morning activities; I think it might end up being Crew 275’s mission song!

In the Upper Deck of the Hab, I watched this morning as crewmembers came and went, to and from different parts of the station, for their cognitive tests, experiments, routine activities, in the Science Dome or Observatory, in pairs or alone. We have definitely settled in a routine, one that we will only realize was extraordinary once we return to Earth!

After eating a delicious focaccia prepared with dill and tomatoes from the GreenHab, Adrien, Quentin, and I went to the Science Dome to prepare our second EVA to Candor Chasma. We had one hour to study the 3D map of the canyon and try to visualize the location of all 10 checkpoints, before we go out on EVA tomorrow. I was surprised to see how differently I worked the problem compared to when I only had the 2D map: because we could “navigate” inside the canyon and see different views of rock formations, Adrien and I started sketching the location of the checkpoints in the order we would find them when exploring the canyon.

By late afternoon, the winds were not too high and the sky was clear enough to open the dome of the solar observatory, and Alexandre was able to observe our Sun for the first time! The telescope is equipped with a Hydrogen-alpha filter, making it possible to look at the Sun’s chromosphere without damaging the eyes. It also allows to see certain phenomena, such as prominences, sunspots, and flares on the solar surface.

Back at the Hab, I saw Quentin working on solving some issues with the location tracking system. Half the crew is now “tagged”, the other half still pending… I am also proud to announce that Crew 275 has the best possible Health and Safety Officer: to help me feel less restless in the evenings, he prepared an entire workout session just for me!

Sol 15 – Cosmic Chasms

“The men on the porch listened. Hearing nothing, they extended their thoughts and their imaginations out and into the surrounding meadows.”

– Chapter 15 of The Martian Chronicles by Ray Bradbury

It’s back to normal for us today, if anything about this mission can be considered “normal”! Corentin got us up and running to start the day with stretching and leg exercises, and we enjoyed breakfast as a crew in the Upper Deck before Alice, Quentin and Corentin had to get ready for the first EVA of the week. The photogrammetry experiment continues! Today’s destination was Candor Chasma, a canyon not far from the station and a place the previous ISAE-Supaero crew had mentioned to us as the best destination for an exploration EVA. The sinuous paths and harsh landscape gave the three of them the opportunity to choose difficult checkpoints to find, which we hope will amplify the added value of the 3D map, compared to its 2D equivalent. After choosing 10 checkpoints, the EVA crew had time to explore Candor Chasma. Thankfully for them, the strong winds we experienced last night dwindled in the early morning, and got stronger after they returned to the Hab, allowing them to use the Parrot drone to 3D-map the canyon. As they ventured out further and further away from the station, Adrien serving as HabCom gradually lost communication with them, and could only “extend his thoughts and imagination” to Candor Chasma with the help of a few bits of radio chatter caught here and there.
While the crew was out on EVA, I visited Alexandre in the observatory. Because of the weather conditions in the past two weeks, very little use of the two MDRS telescopes observatories was made. As the sky gets clearer, Alexandre will be able to start his astronomy project. His objective is to characterize little known asteroids to contribute to an American database. By analyzing the light curve of an asteroid (meaning its luminosity as a function of time), you can deduce some of its characteristics, such as its rotation period, its size, etc. Alexandre’s first observations focused on asteroid Eos. Nevertheless, he was frustrated by the unrelenting wind, as the conditions prevented him from opening the dome of the Musk Observatory and observing the Sun. The observations he had programmed last night were also not performed by the robotic observatory…
In the afternoon, Quentin deployed all the location tracking anchors in the different modules. I toured the station with him as I wore my tag, and he measured the distance between me and the different anchors. Back at the Hab, we checked the data recorded by the trackers, and found that our movements were correlated with it! Quentin is glad to announce that the location tracking system is now fully deployed and operational.
Adrien and Corentin also conducted a large-scale harvest in the GreenHab: dill, spinach and other greens will make our dinner a little more earthly…
