EVA # 08

Author: Meddi MOUMOUNI (GreenHab Officer)

Purpose of EVA:Collecting the resupply at the start of the EVA then going to Marble Rituals to change the batteries of the atmospheric instruments, and Finally going to North Ridge to do Stratigraphy including sketches and drone photos by walking around north ridge main mountain. This will also be a way of testing the drones that encountered some minor battery issues during #05 & #07 EVA. Going back to the MDRS directly after that.

Start time: 9am

End time: 11am

Narrative: Successfully collected the resupply in front of the Hab, then drove to the atmospheric instruments at Marble Rituals to change batteries. When finished, walked back to the rovers to go to North Ridge and stopped the rovers at the intersection of Cow Dung Road & Gateway to Candor. Went to the East and North face of North Ridge and made sketches of the North ridge stratigraphy. We then managed to do some of the drone testing we wanted to do but time ran short so we headed back to the MDRS using the rovers.

Author: Dr. Marina Martínez (Geologist and GreenHab Officer)
Purpose of EVA:
1. Collect geologic samples using the VANTA portable X-ray fluorescence analyzer and other geologic tools. The objectives are 1) to collect the widest variety of lithologic samples during an EVA and 2) obtain compositional analyses in situ to collect samples of high scientific value.
2. Film the crew activities for a documentary (Marta Ferrer, Filmmaker)
3. Fly the drone
4. Take pictures of the corner reflector that is installed next to the base
Start time: 9:45
End time: 13:00
Narrative:
The EVA was successful. We reached each of our different destinations, where we explored the areas, analyzed some samples using the VANTA XRF analyzer, and collected the samples that have scientific value. When we arrived at the MDRS HAB, some scenes for the documentary were filmed and some pictures were taken to the corner reflector. Insufficient light prevented the drone from being flown.
Destination:
1. Midway between Cowboy Corner and intersection between main road (Cow Dung Road 0110) and Brahe Hwy 1572.
2. Cowboy Corner (Cow Dung Road 0110).

EVA #22
Author: Estel Blay
Purpose of EVA: Reflector Calibration & Media Content Creation
Start time: 9:30
End time: 11:30
Narrative:
First, we added rocks to the concrete patch of the reflector to prevent reflections from the concrete surface. This adjustment helps make the calibrations more robust. Additionally, we recorded an interview with the Mission Specialist, in which she explains how the reflector works, as well as the Journalist’s opening video for the 360 virtual tour of the MDRS. Finally, we also recorded a video of us playing with a Barça football ball, which will be used for an upcoming media campaign.

Crew 310 EVA Report 09Feb2025

EVA # 12

Author: Mònica Roca (Mission Specialist)

Purpose of EVA: This EVA had two purposes:

1. Installing one of the horizontal bars in the Corner Reflector structure that will hold the antenna in its final configuration.

2. Taking some images and videos of the reflector, the station, the surroundings of the station using a drone. Also exploring the area of Cowboy Corner from the air using a drone. Getting to Cowboy Corner with the rovers and take the images only walk up to 200 meters from the rovers. On the way to Cowboy Corner were planning to stop at Ridge to take some images.

Start time: 09:30

End time: 12:30

Narrative:
We exited the base and walked slowly uphill to the concrete patch, with the bars and tools needed. We also took the drone with us and took some images and videos of the Corner Reflector installation. Then we proceeded to the CR and installed one of the bars. We realised that the second bar had one of the holes slightly misplaced so we went to the RAM and fixed it. Then we went back to the reflector and mounted the bar. We also took measurements of thew third bar that we will install tomorrow.

We were planning to explore the area of Cowboy Corner, but unfortunately we used all the EVA time with thew Corner Reflector. So we achieved purpose 1 but only partially achieved purpose 2, as we only tool images of the CR and the station.

Destination:

20 meters NW the HAB

Coordinates (use UTM WGS 84): 5185000 E, 4251700 N

Participants: 3: Helena Arias (Engineer) (EVA Leader), Mònica Roca i Aparici (Mission Specialist), and Estel Blay (Health and Safety Officer).

Road(s) and routes per MDRS Map:

For the first part of the EVA, we will walk up the little hill behind the HAB (20 meters NW), up to the concrete area. The second part of the EVA was cancelled, so no route was used.

Mode of travel:
Only walk, we did not use any of the rovers in the end.

EVA # 14

Author: Mònica Roca (Mission Specialist)

Purpose of EVA: Installing the last bar in the Corner Reflector structure that will hold the antenna in its final configuration. Moving the antenna to its final configuration. Fixing to the ground the coaxial cable from the antenna to the received located inside the HAB, with pegs.

Start time: 09:30

End time: 12:30

Narrative:
We exited the base through the RAM airlock and walked slowly uphill to the concrete patch, with the last bar and the tools needed. We also took the drone with us and took some images and videos of the Corner Reflector installation. We proceeded to the CR and installed the last of the bars. Then, we moved the antenna to its final configuration, using the three mounted bars that hold the stick with the antenna on top. We attached the stick to the bars and levelled the antenna and stick. After some adjustments, the installation worked perfectly. Finally we fixed the coaxial cable to the ground with pegs.

With this EVA we have completed the Corner Reflector installation. We are correctly receiving data fro the GNSS antenna, and the first satellite pass from Sentinel-3B will be on the 14th of February at 17:51:40 UTC and Sentinel-3A on the 17Feb at 04:56:16 UTC.
