EVA #: 7

Purpose of EVA: Antoine will conduct an EVA to carry out his field experiment. If conditions permit, a drone will be deployed to capture the images needed for the experiment. If not, the task will be postponed and carried out during a future EVA with other crew members. In the meantime, all participating crew members will analyze the surrounding landscape according to the defined criteria.

Start time: 9:03
End time: 11:37

Narrative: Preparations began at 8:30 AM with the EVA officially starting at 9:03 AM following a radio check. Communication was one-sided throughout: transmissions from the EVA crew were clear, but CapCom-to-crew reception was frequently poor.

The crew traveled along Cow Dung Road, making stops along Brahe Highway 157-2 and at the Overlook, where Antoine’s experiment was conducted due to battery concerns limiting further vehicle travel. An additional stop was made on Cow Dung Road for Matìas’s experiment, during which GPS coordinates were recorded multiple times by the CapCom.

The crew returned to the station at 11:32 AM, reported rover parameters, and completed the standard 5-minute airlock decompression sequence, concluding the EVA.

EVA #: 10

Purpose of EVA:
For Matias’ experiment we will go to the North ridge repeater to see the difference in reception of the different channels (#1 and #2). Then we will go to the Kissing Camel Ridge West, to compare the difference in reception compared to the North ridge, because they are at a similar distance from the HAB.

Start time: 2:00 PM
End time: 04:20 PM

Narrative: They started decompression at 1:55 PM, They headed out on foot towards North Ridge. They arrived at 2:35 PM. They explored the area and found ways to communicate with us on both channels. They left North Ridge at 3:07 PM. They then headed towards Kissing Camel Ridge West (KCRW), but they confused the ridge with another so they arrived 500m north from KCRW. They departed from there at 4:07 PM. and arrived at the station back at 4:25 PM.

EVA #: 11
Purpose of EVA: This time, Joanna will conduct her experiment outdoors with the entire crew. They will head to Cowboy Corner to take advantage of the outdoor setting, without straying too far from the MDRS. The crew will use the Tap Strap to perform the various tasks necessary for the success of Joanna’s experiment.
Start time: 9:05 AM
End time: 10:51 AM
Narrative:
The purpose of this EVA was to support Joanna’s experiment, conducted outdoors with the participation of the entire crew. The team selected Cowboy Corner as the study site, allowing for a suitable field environment while remaining within a safe distance from the MDRS. The crew used the Tap Strap to perform the various tasks required for the success of the experiment.
A minor technical issue occurred prior to departure, requiring a rover reassignment due to a charging problem. The final crew distribution was as follows: Opportunity with Marie and Joanna, and Spirit with Matthias and Zahraa. Once resolved, the crew proceeded to the field without further delay.
The team arrived at Cowboy Corner at 9:25 AM, and the experiment began shortly after at 9:30 AM. All planned tasks were successfully completed by 10:00 AM. Following the experiment, the crew conducted a short on-foot exploration of the surrounding area starting at 10:10 AM, taking advantage of the location to observe the terrain.
The crew departed the site at 10:43 AM and returned to the station at 10:49 AM. Decompression procedures began at 10:51 AM, marking the end of the EVA.
