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.

EVA #18

Author: Marta Ferrer (Documentary Filmmaker)
Purpose of EVA:
Take images in different locations with a drone and a camera of the EVA crew exploring, as well as landscapes, for the documentary film (Marta Ferrer).
Map the North Ridge region with the drone for the drone mapping project (Mònica Roca).
Start time: 08:50
End time: 12:30
Narrative:
We left the base through the airlock and took the rovers to drive north on Cow Dung Road 0110, up to North Ridge, looking for a nice place to take images and videos for the documentary. Looking at the landscape, we went past the North Ridge when the Main Hab contacted us to warn us we were passed the North Ridge. Then, we turned around and went back, parked at the junction with Galileo Road 1104, and asked for permission to drive slightly souther, between Gateway to Candor road and Pooh’s Corner. We got permission to stop the rovers at the junction with Gateway to Candor road. We parked the rovers there and walked a couple of hundred meters south. Once we reached this point, we stayed there for some time to take images and videos. Later we took the rovers again and continued driving south to the junction with the MDRS. We stopped there and continued taking some videos. Finally, we took the rovers and drove back to MDRS.
Destinations:
1st stop: Stopped at Cow Dung road 0110 and Galileo Road intersection.
2nd stop: Parked at Cow Dung road 0110 and Gateway to Candor road intersection and then walked south a few hundreds meters.
3rd stop: Parked at Cow Dung road 0110 with the entrance to the MDRS.

Crew 310 EVA Report 03-02-2025

EVA #1

Author: Anna Bach

Purpose of EVA: Install a giant piece of art in the desert. The image will be captured over the following days with a satellite. This work will require several EVAs. The plan for this EVA is to locate a plain terrain and set up the measuring strings to have a reference to then extend the piece of art. If there is time left we will start extending the fabric. The documentary filmmaker will record the EVA.

Start time: 9AM

End time: 11:15AM

Narrative: We arrived at the location without incidence, and located an area that was plain enough for our purposes. For the first hour we have been setting up the measuring strings, all achieved as expected. The next 30 minutes, we started extending the fabric. This went as planned until the wind started blowing. The fabric was too thin and the wind blew it. After considering the situation, we decided to abort. We collected the fabric and came back to the Hab.

Destination: before crossing Kissing Camel Ridge W.

Coordinates (use UTM WGS 84): 518000 E , 4249550 N

Crew 310 EVA 02 Report 03Feb2025

EVA # 02

Author: Mònica Roca (Mission Specialist)

Purpose of EVA:

• Training EVA.

• Communication test with crew members and with the Hab.

• Checking reflector area, including the concrete pad.

• Measure the distance between the antenna and the HAB using the cable that will be used for the final set up.

• Explore the area for future sample collection.

Start time: 14:15

End time: 16:30

Narrative:
We firstly took Spirit and Opportunity and drove to Compass Rock. The route was taking Cow Dung Road north, up to Galileo Road 1104 east. But unfortunately we missed the turn and continued up north for about a few miles. We contacted Main HAB to ask for our location and received instructions to go back. On our way back we spotted the turn and took it, down to Compass Rock. Once there, we collected geological samples from two different sites for subsequent X-ray fluorescence analyses in the science dome. Once back to the Base from the Compass Rock we walked up the little hill behind the HAB (20 meters NW), explored the concrete area and set the coaxial cable from the concrete patch to the Main Hab, ready for installation with the antenna on future EVAs. When we got inside the Main HAB we realised that we missed one of the crew LilyGo’s during the samples collection. We are planning a Rescue EVA for tomorrow to recover it.

Destination:

• Compass Rock

• 20 meters NW the HAB

Coordinates (use UTM WGS 84): 519000 E, 4250500 N

Participants: Mònica Roca i Aparici (Mission Specialist) (EVA Leader), Helena Àrias (Engineer), Marina Martínez (Geologist and Greenhab Officer), Jenny Garcia (Crew Journalist).

EVA # 4

Author: Anna Bach

Purpose of EVA: Installing and fixing the Corner Reflector structure on the concrete patch.

Start time: 14:27

End time: 16:46

Narrative: We exited the base from the RAM and walked slowly uphill to the concrete patch. We left the RAM with the door almost closed but not locked so we could access it if we needed tools later on. We were carrying the reflector split in two big pieces and the truck full of tools and screws. After reaching the place, we joined together the two big pieces using screws. The reflector was then ready to be fixed to the floor. Anna went down to grab a hammer in the RAM and plug the drill. Then, Mònica and Helena started drilling. Meanwhile Marta was recording it all. After making the holes, Mònica and Helena screwed the reflector to the floor. Time was almost up so we collected our tools and came back to the base. Before entering the RAM, Helena and Anna went to the solar panels to take a picture of Estel’s panels. Mònica and Marta waited in front of the RAM. Then the four of us entered the RAM. Overall, the EVA was a success and the reflector will likely be finished in the next EVA.

Destination: 20 NW the HAB
