EVA # 3
Author: Leanne Hirshfield
Purpose of EVA: 1) A short EVA to Marble Ritual with Commander equipped with neurophysiological and behavioral sensors to assess range of sensors and data quality during EVA-related movement (e.g.,walking, riding in rover, standing still on Mars). The Health and Safety Officer supported the Commander throughout the EVA. The task included travel to Marble Ritual and then walking to find one waypoint within 300 meters of Marble Ritual. Commander reported observations from waypoint and collected one biological sample to bring back to the Hab.
Start time: 10:30
End time: 11:45
Narrative: Suits (2 and 7) and Radios (1-2) fully charged before leaving and plugged in upon return. Arrived to Marble Ritual around 10:40 AM, and ran sensor testing study outlined below. Arrived back on site around 11:45 AM. Both depressurized before entering the Hab. Perseverance Hours (before EVA): 169. Beginning charge: 100%Perseverance ending charge: 82%. Perseverance plugged in upon return. EVA #3 was a huge success! We learned a lot about the process of collecting eyetracking and fNIRS data out on EVA. We brought the data acquisition laptops with us and ran through our study protocols pretty seamlessly. Things we learned: everything is harder to do on EVA: from sensor troubleshooting to simple breath holding studies (breath holding results in a lovely hemodynamic response in the brain that we can measure with fNIRS). Very little room for experimenter error if we want to collect actual field data in the future. Emily was able to quickly convert our walkie talkie communications into transcripts with WhisperAI, and our review of the discourse suggests that this would be a rich source of team cohesion and team processes data that we could apply NLP techniques to in future collections. Good stuff and very much a learning experience!
Destination: One location: between the HAB and Marble Ritual.
Coordinates (use UTM WSG 84): 518250,4251000
Participants: Leanne Hirshfield (Commander) and James Crum (Health & Safety)
Road(s) and routes per MDRS Map: Cow Dung Road, North direction, and then walking within a 300 meter radius around Marble Ritual.

EVA # 4
Author: Emily Doherty
Purpose of EVA: 1) A farther EVA to Pooh’s Corner with Crew Engineer equipped with neurophysiological and behavioral sensors to assess range of sensors and data quality data quality during EVA-related movement (e.g.,walking, riding in rover, standing still on Mars).. The Journalist will support the Crew Engineer throughout the EVA. The task will include travel to Pooh’s Corner and then walking to find one waypoint within 300 meters of Pooh’s Corner. Flight Engineer will report observations from waypoint and collect one biological sample to bring back to the Hab.
Start time: 14:15
End time: 15:45
Narrative: Decided to venture to Marble Ritual instead of the original planned Pooh’s Corner due to a delayed start. Upon arrival to Marble Ritual, we spent about 30 minutes troubleshooting our sensor equipment. We then spent about an hour testing the range and feasibility of the sensors in high sunlight conditions. We arrived back at the Hab around 15:45 and depressurized before entering.
Destination: One location: between the HAB and Marble Ritual.

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 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

Coordinates (use UTM WGS 84): 518000, 4251000

Participants: Mathurin, Erin, Léa

Purpose of EVA: Changing batteries of the atmospheric instruments and protecting them from the wind

Start time: 7:58

End time: 09:23

Narrative: The goal for this EVA was to change batteries of the atmospheric instruments near Marble Ritual. We had difficulties retrieving some data from the instruments but in the end, we succeeded. We turned off LOAC to bring it back to the station due to the weather. We turned off and protected the field mill with protective foams. The wind started to blow hard when we decided to go back to the station because our goals were achieved.
