Journalist Report – February 26th

SOL 8: Who run the Hab? Girls!

« The boy felt jealous of the freedom of the wind, and saw that he could have the same freedom. There was nothing to hold him back except himself. » – The Alchemist, Paulo Coelho

This morning the first EVA of photogrammetry took place. Particularity: it was a 100% masculine EVA! All the boys went out on the Martian atmosphere, letting the Hab free for the four girls of the Crew. Outside, Mathurin piloted the drone and took photos of North Ridge with it, to later generate a 3D map of the site during the data handling session that they did this afternoon. Winds blew this morning; the drone could hardly take off. As the HabCom of the EVA, I told them information every 10 minutes about wind speed thanks to our weather station, installed during a previous EVA. In the Hab, girls were working on experiments: Marie was dealing with the AMI interface, Léa kept training on astrophotography, Lise watered the GreenHab’s plants while Mathurin was out of the station and, as I said, I was HabCom for the boy’s EVA. Despite it all, we were very happy to get the Crew reunited at the end of the morning.

During the afternoon, Yves finished teaching the Crew about the EchoFinder experiment, by teaching Leo and Léa. Now, everyone can perform ultrasounds on Marie and knows how to use the experiment’s software. At each session, we are searching for five organs, like the carotid for example, helped by augmented reality and artificial intelligence to take good quality images of the organs. Operators of the experiment take notes about remarks they want to share with the researchers for them to perfect the software, in order for it to be used one day during space missions.

Finally, Lise retrieved last week’s data for the Orbital Architecture experiment. This experiment, which was brought to the ISS three weeks before the beginning of our mission, aims to study the impact of the station’s architecture and environment on the analog astronauts. We perform three cognitive assessments per Crew member per week in different modules, we wear location tracking sensors and polars to measure our heart rate. The results of the tests, of the location tracking sensors, and of questionnaires that we fill enable the researcher from the University of KTH to analyze our performances!

SOL 7: “Carpe Diem”

“It’s the simple things in life that are the most extraordinary; only wise men are able to understand them.” – The Alchemist, Paulo Coelho

Today it’s Sunday at the MDRS! The day started a bit later than usual: we woke up at 8:30 instead of 6:45! The daily workout session was longer too: we enjoyed a one-hour session with lots of cardio exercises, to get us in shape for the day. For breakfast, Mathurin and Yves cooked pancakes for the Crew. They were delicious, and we ate so many of them with maple syrup that we decided to avoid lunch and just have brunch!

Then, Sunday means clean-up! Since we arrived at the station, we had not taken the time to fully clean the Hab. This morning, we cleaned up all the tables, countertops, and cooking utensils. We keep a close watch on our water consumption every day, and we are very careful not to waste water, even during cleaning. Léa vacuumed, after struggling to make it work. After a week, the floor was dirty… But now, everything is clean and well tidied up for next week, and this has given the Crew a real boost! Finally, we erased the white bord we used to track our daily task, now that they’re implemented in the AMI interface. That way, we could write quotes on it, like “Carpe Diem”!

During the afternoon, we enjoyed some downtime, not forgetting some essential tasks: Yves collected data for all the experiments we performed during the week, and some Crew members took cognitive tests for the Orbital Architecture experiment. But we made sure everyone was well rested, whether it was reading, or knitting, or crocheting, or making a puzzle and listening to music… The mood is great for this first Sunday on Mars!

Sol: 7

Summary Title: Carpe Diem

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

For our first rest day of the mission, we allowed ourselves a little more sleep than usual; for the first time since our arrival on Mars, I was awoken by sunlight rather than by my alarm. Our Crew HSO had prepared an hour-long workout session, which only made us enjoy the pancakes even more afterwards.

After an efficient and thorough clean, the Hab is as good as new ! The Crew then spent the rest of the afternoon in the Hab, resting for some, working on personal projects or on data collection for others. We are ready for a productive and intense second week, marking the start of the photogrammetry experiment and the launch of AI4U

Look Ahead Plan:

Our first photogrammetry EVA at North Ridge is planned for Sol 8, which will be dedicated to generating a 3D map of the area. This map will be given to part of the Crew to prepare an exploration EVA, during which the team will need to identify pre-defined checkpoints. The objective is to compare the performance of a team given a regular 2D map (Sol 10), and a team given a 3D map (Sol 12) of the same area.
