Crew 279 EVA Report 03-04-2023
EVA #01
Author: Ioana Dimitrova
Purpose of EVA: Training EVA + communication test with crew members and with the hab.
Start time: 9:20
End time: 10:10
Narrative: The goal of the EVA was to get comfortable with the spacesuits, the protocole and the environment. Preparation went well but during the decompression in the airlock, we had trouble hearing what one of the crewmembers was saying. We aborted the decompression and tried to fix the problem. We put the walkie talkie on the other side of the person’s chest, played with the cable a little bit, redid the whole procedure for radio and helmet and tried again, everything seemed to be working fine. The first part of the EVA consisted of getting to the Marble Ritual with the rovers. The second part was to walk around the Marble ritual area to discover the place and to get acquainted with the spacesuits, the radio communication and the particularities of the soil. This walk consisted of 20 min of the EVA. No communication problems seemed to exist. Exploration was nominal. The third part was the return to the Hab with the rovers. Upon arrival, the crewmember who had a problem with the radio prior to the mission, tried to communicate the rover numbers to the Hab and it was at that moment that we noticed that his comms were not working properly. It was time to end the mission anyways, so we went inside after decompression.
The crewmember in question is not the chatty type, so even if the problem occurred earlier in the EVA, we didn’t notice the problem then. Our hypothesis is that there is a problem with the headset because we tested the radio with another headset and it seemed fine. The headset doesn’t seem to be able to be fixed. During the next EVA, the crewmember in question will use another headset with his radio.
