2022-2023 Field Season (#22)

Report title: EVA Report

Crew #: 335

Position: GreenHab officer

Sol: Day 4

EVA #7

Purpose of EVA: To collect clay

Start time: 14.30

End time: 16.50

Narrative: The EVA began later than planned due to technical issues with equipment brought by the film crew. This caused a delay in departure and required some troubleshooting before we were able to proceed safely. Additionally, we encountered an issue with the rover Curiosity, which showed a rapidly declining battery level while reading the SOC at rest (see op report). To avoid risk, we switched to the rover Spirit, which performed reliably for the remainder of the EVA.

Despite the delayed start, the journey was highly enjoyable. We traveled toward Candor Chasm, taking time to appreciate the landscape along the route. Upon arrival, the team made multiple stops to explore the area more closely. Three of the crew descended into the chasm, while the commander remained a little further back at the chasm entrance near the rovers to maintain consistent communication with HabCom and the crew.

During exploration, the team identified a deposit of black clay, which appeared scientifically interesting. A large sample was collected and transported back using a bucket, though carrying it proved physically demanding. On the return journey, we made several additional stops to gather more clay samples from different locations to ensure a broader collection.

Overall, morale remained high throughout the EVA. The combination of productive scientific and creative work, smooth rover operations after the switch, and the striking environment contributed to a very positive and enjoyable experience for the entire team.

Destination per MDRS Map: Candour Chasma, and we stopped along Galileo and Cow Dung Rd.

Sol: 4

EVA #: 6

Purpose of EVA: The objective of this EVA is to refine and complete evaluation of operational differences in drone piloting with and without an EVA suit. Participants will reestablish baseline control from the observation deck without a suit, followed by replicated operations outside the fence while in full protective equipment.

Start time: 9:30

End time: 10:00

Narrative: Crewmates departed the Hab at 09:30 and proceeded on foot toward the Solar Observatory as planned. Upon arrival, the team completed several operational circuits using the drone system from the observation deck where no EVA gear was needed.

As operations progressed, wind conditions began to increase, gradually impacting both drone stability and operator comfort.

Due to the continued rise in wind intensity, the EVA was concluded early. The team safely returned and secured all equipment without issue. Remaining test objectives will be rescheduled and completed during a future EVA under more favorable environmental conditions.
