SOL 20: Back to the Canyon

“I’ve crossed these sands many times,” said one of the camel drivers one night. “But the desert is so huge, and the horizons so distant, that they make a person feel small, and as if he should remain silent.” – The Alchemist, Paulo Coelho

This morning, Crew 293’s last EVA to Candor Chasma took place! Léa and I had to find 12 checkpoints scattered all along the canyon. We prepared the expedition yesterday thanks to a 2D map and a topographic map. Mathurin was with us during the EVA: his goal was to count our steps, to take notes about our timing and performance. As we were getting closer to the site with the rovers, Mathurin had to stop his rover sooner than Léa and I, because his battery had drained faster than ours, and he would not have been able to come back to the station if he had continued. Léa and I continued driving Opportunity, to get as close as possible to Candor Chasma, and to limit our walking time to the canyon. Of course, we kept Mathurin in our line of sight at all times. Even though we found almost all of the checkpoints in less than an hour and a half, the 3D team was more efficient yesterday… But we are very proud to have managed to get this far, and we performed better than last week at North Ridge! Plus, going to Candor Chasma means enjoying its exceptional geology. Upon arriving at the end of the delimited search area, we were amazed to notice how far the canyon extended. The large rock tours surrounding us made us feel tiny compared to the Martian terrain’s wideness!

Back from the EVA, we were very tired. A 4-hour hike under the Martian Sun, while climbing on rock walls, is exhausting! We were lucky to just have to sit at the table to eat a plateful of good mashed potatoes from MELiSSA that was waiting for us! During lunch, we recounted our EVA to the rest of the Crew, and Crew members who stayed at the station brought us up to speed as well. Yves, who was our HabCom, cooked a brownie for dessert, Leo took care of the GreenHab, and Marie and Lise confronted both the software and hardware problems of the EchoFinder experiment. Everyone was productive during the absence of the EVA Crew!

During the afternoon, after some Crew members rested for a while, everyone followed its planned activities. Léa made impressive solar observations for her astronomy project. Yves and Marie tried once again to make EchoFinder’s equipment work for another session, which wasn’t very successful…

For the past few days, Lise and Leo have been preparing in secret an activity for tomorrow, that they finished today. We can’t wait to see what it is, and to enjoy tomorrow to rest. We need to be in good shape for our last week on Mars!

SOL 22: Good Vibes Only!

“Don’t forget that everything you deal with is only one thing and nothing else. And don’t forget the language of omens. And, above all, don’t forget to follow your Personal Legend through to its conclusion.” – The Alchemist, Paulo Coelho

To start the week on a good note, Yves and Mathurin initiated the last step of the Photogrammetry experiment. During their EVA, they went to Kissing Camel Ridge in order to take pictures of the area and to generate 2D and 3D maps of it. Twice we explored the northern part of the station’s surroundings, but this time, we turned right after leaving campus, taking the southbound road! It enabled us to discover new Martian landscapes… During this EVA, Yves and Mathurin needed to be with another Crew member. This time it was Lise, instead of Leo the two previous weeks. Lise, who had loved searching for the checkpoints in the previous destinations, was on the other side of the experiment this time, and she loved it all the same! Her goal, with Yves, was to find where to put the checkpoints while Mathurin was taking the hundreds of drone pictures. During the week, there will be new exploration teams with the 2D or 3D map. This is the last iteration of an experiment we all very much enjoyed participating in!

Meanwhile, Léa and Marie wrote some new outreach articles for our website, and every Crew member who wasn’t out on EVA was busy accomplishing their planned tasks, from experimental data handling to cognitive assessments in the Hab or GreenHab.

The MELiSSA activity, prompting us to cook meals with fresh vegetables and not only dehydrated food, continues to delight the Crew! Today for example, Léa and I cooked a very tasty carrot cake for lunch. Crew members who were out on EVA enjoyed this great meal after being out for a few hours. Then, in the early afternoon, Lise and Mathurin tried to solve problems they had in their code for retrieving data from our smart watches and impedance meter. They put in common everything they had done on their own. At the end of the afternoon, we all enjoyed a virtual reality experience: in this personalized video for each of us, we were surprised to see Arnaud Prost, a French astronaut, wishing us good luck and giving us advice for the end of our mission! This video cheered everyone up, and gave us that final bit of motivation we needed, to end all of our studies and experiments in a grand finale!
