EVA #: 2

Purpose of EVA: We are heading out to scout the area and check that all the equipment is functional in the field.

Start time: 2:05 p.m.
End time: 3:37 p.m.

Narrative:
At 2:05 PM, the crew completed decompression and boarded the rovers Perseverance and Spirit, marking the beginning of the EVA. The first stop was Pooh’s Corner, where the team familiarize themselves with the terrain and conducted initial communication tests between the station and the EVA crew.

At 2:36 PM, the crew returned to the rover and departed for the second stop. A minor GPS issue arose during transit but was quickly identified and successfully resolved, allowing the mission to proceed without delay. Upon arrival at Cowboy Corner, the team explored the area and initiated a search for potential fossils, taking time to observe the geological features of the site.

At 3:19 PM, the crew left Cowboy Corner and headed back to the station, arriving at 3:29 PM. Decompression procedures began at 3:32 PM and were successfully completed at 3:37 PM, marking the end of the EVA.

EVA #: 8

Purpose of EVA: The team went to Antoine’s experiment site to conduct the experiment. Antoine explained his experiment before the EVA. All participating crew members will analyze the surrounding landscape according to the defined criteria.

Start time: 2:06 p.m.
End time: 3:49 p.m.

Narrative: Preparations began at 1:30 PM with the EVA officially starting at 2:06 PM 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 to the destination they arrived with no further news. They started completing the document for Antoine’s research. They finished at 2:44 PM, so they went exploring to Sea of Shells. They drove carefully because the roads were difficult.

The team climbed a hill to have better visibility. They got back into their rovers and headed back. The crew returned to the station, reported rover parameters, and completed the standard 5-minute airlock decompression sequence, concluding the EVA.

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.
