SOL 24: Mission objective: Save the station!

“The boy was beginning to understand that intuition is really a sudden immersion of the soul into the universal current of life, where the histories of all people are connected, and we are able to know everything, because it’s all written there.” – The Alchemist, Paulo Coelho

This morning, we headed to the atmospheric instruments’ site to change the batteries and retrieve the data recorded during the past days. The drone, piloted from the inside of the Science Dome, was flying above us to take pictures! Then, Leo, Yves and I went to reach checkpoints chosen on Monday at Kissing Camel Ridge. Yesterday, we prepared our path with the 3D map, and we were very efficient! We found the first seven checkpoints in 30 minutes, but then, we were incapable of finding the eighth one for a long time… Finally, we found 11 out of 12 checkpoints placed on the site. We are proud of our performance, and Leo is very happy to have been able to test the experiment from this side, and to search for checkpoints as quickly as we could. We are impatient to see how Marie and Léa will manage their search with the 2D map, because at the end of the afternoon, they prepared their strategy for tomorrow’s EVA!

In the morning, the rest of the Crew continued working on different experiments or tasks, such as taking care of the GreenHab, performing solar observations for our Crew Astronomer, or trying to fix the EchoFinder equipment. The afternoon resumed the same way, after the EVA: Yves was handling photogrammetry data, Léa and Marie performed an EchoFinder session. I was working on the morning EVA’s pictures, sitting in the Hab, and Lise was also working on her computer next to me. Suddenly, at 16:08, an alarm rang on the AMI interface, so we stopped our activities. We were used to the procedure: we had to check a sensor in the Science Dome. Marie and Léa were already there, so they could check. Contrary to most of our alarms, which are just sensor anomalies, the risk was real this time! The alarm wasn’t a false alarm. One of the tunnels which connects different modules, near the Science Dome, had been damaged and caused a depressurization in a section of the station! After being reunited safely at the Lower Deck of the Hab, we organized ourselves to be efficient in applying the emergency EVA’s protocol: we had to go out in EVA suits to fix the station. Mathurin and I were equipped with our suits and worked on the tunnel from the outside of the station. In parallel, Léa was also equipped for the EVA, but on the inside of the station, in the tunnel. We communicated together by radio, and with Marie, who was the emergency HabCom, to be well coordinated during the operation. We even had a rover with us to maintain the tunnel while doing the necessary manipulations. We fixed the broken part of the tunnel, all in just one hour of EVA! At the end of the outing, we were happy to have fixed our home, and now we are all safe inside the station!

The day was very exhausting for the Crew, as we continued with the Coms window. Two EVAs in one Sol, that never happens ! We enjoyed the evening to rest, but also to coordinate the end of the mission, organize our last tasks and to think about the dismantlement of all our equipment and experiments!

Crew 293 EVA Report 13/03/2024

EVA # 17

Author: Mathurin FRANCK

Purpose of EVA: Emergency EVA

Start time: 4:35 am

End time: 5:50 pm

Narrative:

→ 4:08pm depressurization alarm, Yves radioed every module and alerted all Crew members of the depressurization. Pressure sensor checked in the Science Dome, depressurization warning confirmed by the interface.

→ All crew members accounted for and returned to the Hab, wearing oxygen masks (NB: FFP2 masks)

→ Commander took control of the operation and designated herself as HabCom. She also designated:

1 crewmember (Int1 : Léa ) tasked with helping with repairs from the inside of the tunnel
2 EVA crew members (Ex1 : Mathurin and Ex2 : Erin). Ex1 is EVA Leader.
First, two new picket fences were put in place. There was no metal wire in the RAM, we used zip ties to fix the picket fences to the cage. Then we removed the handbrake of the robotic rover to loosen the rope. We put the handbrake back and untied the rope. We then put back the tarp and secured it with zip ties.

Note that the zip ties we had are not very big, so we had to put a lot of them to be extra secure.

Objectif of the EVA: Fix Science Dome tunnel

Destination: Science Domes tunnel

Coordinates (use UTM WGS 84): 518000, 4251000

Participants: Mathurin, Erin, Léa

Road(s) and routes per MDRS Map: None

Crew 293 Sol Summary Report 13-03-2024

Sol: 24

Summary Title: Mission objective: Save the station

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

No Sol on Mars is uneventful, especially when one gets closer and closer to the end of their mission… This morning, the last exploration EVA supported by 3D mapping took place at Kissing Camel Ridge, involving the Crew Engineer, Crew Journalist and Crew Scientist. As the Journalist and Engineer were searching for checkpoints, suit n°5 stopped working. While the Crew tried troubleshooting on site, they could not find the source of the issue, and the EVA had to be continued out of sim for one of the EVA crew members. Once they were all safely back at the Hab, the Crew Engineer was able to figure out the source of the issue.

Meanwhile, after doing some more troubleshooting on the Echofinder tool, we have decided to continue running the experiment without the AI assistant, using only Augmented Reality. One session was performed this afternoon, the final one will take place on Sol 25.

With the help of Mission Support, we were also able to test our Anomaly Monitoring Interface, while simultaneously performing a meaningful fix outside the station. At 16:08, a programmed depressurization alarm resounded, prompting the crew to follow a realistic emergency EVA procedure. The objective was to repair the tunnel to the Science Dome; the designated crew was successful, the tunnel is now much safer to travel through. The interface test was also successful. We believe this tool could be a great addition for future simulations.

Look Ahead Plan:

The final exploration EVA for the Photogrammetry EVA is to take place on Sol 25. We aim to dismantle the atmospheric instruments on Sol 26, before breaking sim at 6 PM.

Anomalies in work: EVA Suits 7, 9

Crew 293 EVA Report 13Mar2024

EVA #016

Author: Erin Pougheon (Leader)

Purpose of EVA: Changing batteries of atmospheric instruments and retrieving data, go to Kissing Camel Ridge to search checkpoints with a 3D map, generated with photogrammetry. Pictures will be taken from a drone, put outside by the EVA team

Start time: 8:50

End time: 12:30

Narrative: The EVA started well with the change of batteries at the atmospheric instruments. Meanwhile, a drone pilot took drone pictures of the EVA team and of the station during the first 30 minutes of the EVA, from inside. The EVA team then went to Kissing Camel Ridge and started to search for the checkpoints. One hour into the EVA, one crewmember had a problem with their suit (Suit 5), it turned off. The problem was not identified during the EVA, it seemed to be a circuit issue, not a battery one. The EVA team chose to go on with the EVA with the suit on, but without the helmet, for said crewmember. The EVA team chose to put safety and science first and go on with the photogrammetry experiment, because either way, the helmet had to be taken off to come back to campus, thus simulation was already broken. The EVA team continued to search for checkpoints and came back alright to campus.

Once the EVA Crew was back at the Hab, the Crew Engineer could figure out what the problem was. See Operations report for details.

Crew 293 Operations Report 13-03-2024

SOL: 24

Name of person filing report: Leo Tokaryev

Non-nominal systems: Suit 5, but it’s fixed now.

Notes on non-nominal systems: During the EVA, the suit suddenly stopped working. We tried firstly not to break the sim, and open the suit to see if the battery was correctly connected, it was. Then, it was clear that repairs needed more time, so we were forced to take the suit out and inspect it. We couldn’t identify the problem because I wasn’t used to this kind of problem. See HSO report for the decision we took.

After the EVA, I had more time to look into it and test it, the problem was in the red cable, which didn’t seem to work properly. I replaced the orange connector (a small one, with 2 teeth) that was in the red cable, and the suit worked fine. The problem was not the battery.

Questions, concerns and requests to Mission Support:

During the emergency EVA, we didn’t find a metal wire, we have looked for it previously, but didn’t find it either. Thus, it could be a good idea to have in the RAM for different repairs.

Also, there’s lots of zip ties in the RAM, but they’re all too thin, I saw one or two zip ties that broke on the tarp leading to the science dome, and I couldn’t replace it because I didn’t have the same, thick zip ties that were used previously.

Also, regarding the suit problem, it could be useful to tell the future crews about it, since it is a problem that could be easily solved during an EVA, without breaking sim. I was lucky to have the needed part taped inside the suit, but I believe it is not the case for all the suits( I didn’t have time to look into every suit, but suit 8 for example didn’t have this replacement part taped). I could only thank the person that taped it inside the suit and suggest buying some replacement parts (I don’t know if there’s already some replacement parts of this type in the HAB), and tape them in every suit.

SOL 23: The calm before the storm

“As each day passed I would learn, in our talk, something about the little prince’s planet, his departure from it, his journey. The information would come very slowly, as it might chance to fall from his thoughts.” – The Little Prince, Antoine de Saint-Exupéry

Today was our last day of mission without performing an EVA! Indeed, from tomorrow to Friday, we planned one EVA per day, for the last week of photogrammetry or to retrieve the atmospheric instruments before the end of the mission. No EVA means a lot of work inside for the Crew, whether on our computers or on equipment for experiment inside the station. For example, this morning, after a magnificent sunrise, Mathurin and I tried to find a solution to a problem we have with our outreach experiment, built with high-school students, to grow plants in Martian soil. Indeed, we noticed yesterday some mold on the red planet’s soil, and even after observing it with the microscope, we can’t understand where the problem comes from! Talking about experiments, Léa continued working on her informatic code which enables her to analyze sunspots on Sun’s pictures taken thanks to the Solar Observatory. Yves and Lise finished preparing the Kissing Camel Ridge 3D map made thanks to photogrammetry during yesterday’s EVA. They located all the checkpoints on the map, for us to find them during our next EVAs! A day inside also means maintaining the station. Leo solved in a few minutes the problem we had with our kitchen sink. Indeed, for a few days, the water was hardly draining. It was becoming complicated to wash dishes : we are using 4 liters of water only each time we wash the dishes for a 7 person meal, so the water becomes dirty really quickly. We are really grateful to our Crew Engineer because thanks to him, we have our functional sink back.

At the end of the morning, Marie and Leo were cooking for us for the last MELiSSA meal of the mission. The recipe was the one with the vegetable gnocchi that we already tested and liked, even though it is not very fast to prepare for a Crew! The end of this experiment made us realize the amount of data we produced during four weeks of mission, and how much productive we were! We can’t wait to give feedback to the researchers about the experiment we conducted, and especially we can’t wait to see the results provided to science thanks to our mission!

At the end of the day, Leo and I prepared our EVA for tomorrow, during which we’ll have to reach checkpoints placed at Kissing Camel Ridge. We relied on the 3D map of the area, and we took notes and drew to be able to find each checkpoint once on site! It will be the first time for Leo to perform an EVA in which he’ll have to search for checkpoints and not to place them! Meanwhile, other Crew members were working on other subjects that are keeping us busy for more than three weeks! Being seven in the Crew enables us to split the tasks and to be efficient on each experiment we brought with us to the station.

Crew 293 Sol Summary Report 12-03-2024

Sol: 23

Summary Title: The Calm before the Storm

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

Today was our last Sol with no EVA planned, before the final sprint. The Crew is starting to plan for post-mission data collection and analysis, as well as logistical considerations. We spent the day continuing to run experiments, and most notably preparing the last MELiSSA meal. We are looking forward to sharing our results with all of the researchers who are counting on us!

In the afternoon, more coding, more data handling, more work… A routine is definitely established, and it’s almost frustrating to see that we are going to have to leave Mars soon after having found a stable rhythm. But the next three Sols will be far from a smooth ride: all of our studies need to be wrapped up, the last bits of data collected, and preparations for our trip to Earth made.

Look Ahead Plan:

The two exploration EVAs at Kissing Camel Ridge (involving a 2D team and a 3D team) are scheduled on Sol 24 and Sol 25. We aim to dismantle and retrieve all atmospheric instruments on Sol 26 (morning), and to break sim at 6 PM.
