EVA # 5
Author: Tomás Burroni
Purpose of EVA: Collect drone images from el Dorado Canyon to generate the digital elevation model for the second EVA and gather more data for the geolocation project.
Start time: 9:00 am
End time: 11:00 am
Narrative:
We drove from the HAB South through Cow Dung Rd, parking at Zubrin’s head. There, we first took 10 min to do the programmed drone flight to generate the map for the second EVA. We then started walking eastwards into the Canyon and took a soil sample at (519371, 4248609). While inside the Canyon one of the crew members realized that the sound from the suit’s had lowered in intensity. We tried turning it off and on again and they felt that the difference in airflow was lower than expected. This was not noted before as there had been no fog build up in the helmet and the chilly temperature allowed them to stay comfortable even with lower airflow. At that moment we headed straight back to the rovers and the Hab instead of taking the second soil sample as planned. It was not deemed necessary to remove their suit on the way back as the crew member was not suffocating and the helmet was not fogging up.
