EVA Report – March 3th

Crew 263 EVA 14 Report 03-03-2022

EVA # 14

Author: Léa Rouverand

Purpose of EVA: Replacing the batteries for the atmospheric experiments, Analysis of geology transition zones using a handheld LIBS (Laser-Induced Breakdown Spectroscopy) analyzer.

Start time: 09:00

End time: 11:27

Narrative: EVA Participants entered the airlock at 09:02. Depressurization ended at 09:07. EVA participants checked the rover batteries. The obtained information is:

Perseverance: Usage Duration – 228.1 Battery Charge – 100%

Spirit: Usage Duration – 157.2 Battery Charge – 100%

Opportunity: Usage Duration – 85.1 Battery Charge – 100%

Curiosity: Usage Duration – 169.1 Battery Charge – 100%

The EVA participants took Opportunity and Curiosity at 09:11 and drove on Entrance Road until Cow Dung Road. Batteries of the Atmospheric Experiments -LOAC, Mega-Ares, Purple Air- were replaced. The old batteries were placed on the rover trunks (09:17).

The participants drove on Cow Dung Road until Marble Ritual, as the road was muddy, the participants they stopped and parked the rovers along Cow Dung Road at 09:19. The EVA participant walked on Cow Dung Road until the junction with Stream Bed Connector (09:40).
They walked on Stream Bed Connector and reached two points of interest at 10:00 (the two points of interest were located at 519704E 4251292N and 519574E 4251279N).

The EVA participants stayed about an hour in this area, they proceeded on sketches, pictures and taking LIBS measurements. A drone was launched to take pictures of the study outcrops and to identify the entrance to Candor Chasma (area of interest for future geology studies).

At 11:00, the participants left the points of interest. At 11:21 they reached the rovers parked on Cow Dung Road

At 11:25, the participants arrived at the Hab:

Opportunity: Usage Duration – 85.2 Battery Charge – 97%

Curiosity: Usage Duration – 169.2 Battery Charge – 97%

They entered Airlock and at 11:27, the pressurization was over at 11:32.

Destination: Zone F -final point of interest reached located on the Stream Bed Connector road at 519704E 4251292N

Participants: Léa Rouverand (EVA leader), Nicolas Wattelle, Mathéo Fouchet, Valentine Bourgois. HabCom was Cerise Cuny.

Road(s) and routes per MDRS Map: Entrance Road, Cow Dung Road

Mode of travel: Rover on Entrance Road and Cow Dung Road till Marble ritual, foot on Cow Dung Road and on Stream Bed Connector.
