EVA # 7
Author: David Mateus
Purpose of EVA: Test search and rescue protocol in a canyon. And explore the Canyon.
Start time: 9:00 pm
End time: 11:10 pm
Narrative:
Following the route, we drove from the HAB to Cowboy Corner. We parked at that point and walked towards the canyon. Once inside the canyon, we waited for our crew members from the other team who were at the HAB and awaited the arrival of the drone to carry out the search and rescue simulation. It was not possible to fly the drone to the Canyon due to the winds. The crew returned safely to the Hab.

EVA # 5
Author: Tomás Burroni
Purpose of EVA: Collect drone images from el Dorado Canyon to generate the digital elevation model for the second EVA and gather more data for the geolocation project.
Start time: 9:00 am
End time: 11:00 am
Narrative:
We drove from the HAB South through Cow Dung Rd, parking at Zubrin’s head. There, we first took 10 min to do the programmed drone flight to generate the map for the second EVA. We then started walking eastwards into the Canyon and took a soil sample at (519371, 4248609). While inside the Canyon one of the crew members realized that the sound from the suit’s had lowered in intensity. We tried turning it off and on again and they felt that the difference in airflow was lower than expected. This was not noted before as there had been no fog build up in the helmet and the chilly temperature allowed them to stay comfortable even with lower airflow. At that moment we headed straight back to the rovers and the Hab instead of taking the second soil sample as planned. It was not deemed necessary to remove their suit on the way back as the crew member was not suffocating and the helmet was not fogging up.
Destination: Zubrin’s head (vehicle + walking in site)
Coordinates (use UTM WGS 84): 519371 E, 4248609 N
Participants:
· Luis Díaz
· Tomás Burroni
· Andrés D. Reina
Road(s) and routes per MDRS Map: N Cow Dung Rd and Galileo Road.
1. Took East on Entrance Road (Drove)
2. Turned right onto Cow Dung Road (Drove)
3. Walked to the entrance of canyon
4. Walked into the canyon towards the East
5. Returned by the same route.
Mode of travel: Driving on the rovers Opportunity and Curiosity and walking around the canyon, located nearby.

Crew 285 EVA Report 03-11-2023
EVA # 3
Author: Andrea de la Torre
Purpose of EVA: Continue the mapping of Candor Chasma with the drone and make a 2D path to follow with the QFIELD app.
Start time: 9:00 am
End time: 11:45 am
Narrative:
Our mission was focused on capturing GPS coordinates throughout the journey to create a digital route that our colleagues can follow with a mobile app, leveraging the fact that one of our EVA team members was already familiar with the location. Additionally, we deployed an automated drone flight over the Candor Chasma canyon to generate an orthomosaic, a 3D model, and a DMS chart for analyzing the final exploration area for the next EVA team. Furthermore, we collected a soil sample to further our construction material project, using a different type of soil than in previous EVAs.
Destination: Candor Chasma
Coordinates (use UTM WGS 84): (520500,4251000)
Participants:
· David Mateus
· Luis Diaz
· Andrea De La Torre
Road(s) and routes per MDRS Map: N Cow Dung Rd and Galileo Road.
Mode of travel: driving from the HAB north through Cow Dung Rd, turning into Galileo Road. We parked 300 meters before Compass Rock because the SOC of Perseverance was at 65% and we walked to the entrance of the canyon of Candor Chasma.

EVA # 1
Author: Luis Diaz
Purpose of EVA: Collecting Martian regolith samples, suiting up with the use of spacesuits, and drone flight.
Start time: 11:05
End time: 12:15
Narrative:
We headed to Marble Ritual to take soil samples and sent the drone to conduct exploration shots in the Candor Chasma area; however, we experienced a slight delay of 2 minutes as we deviated a few meters off the path, quickly returning to the right route.
Once at the scheduled destination point, Andrés began collecting 3.3 kg of Martian regolith while Luis and Marina deployed the drone to execute automatic photo capture tasks for the subsequent generation of a 3D model and contour lines. These will enable us to identify future exploration zones.

Purpose of EVA: Geologic sample collection

Start time: 10:00

End time: 12:00

Narrative: Emily, Deb, and Darin drove to 1101 (the road to Barrainca Butte), where they stopped to collect specimens from the wash on the west side of Cow Dung Rd. After collecting specimens, they returned to the rovers and drove north on Cow Dung Road to the southwest side of Kissing Camels Ridge. There, they collected additional rock specimens along the wash on the west side of Cow Dung Rd before returning to the rovers and continuing on back to the Hab.

Coordinates (use UTM WGS 84): 519700, 4247300 and 518200, 4249300

Participants: Emily Apgar, Deb DeBerard, Darin Orton

Road(s) and routes per MDRS Map: Crew took rovers from the Hab, turned south on Cow Dung Road, and continued to Route 1101 (the road to Barrainca Butte). They did collect specimens on foot in the wash near the road. From there, they returned North on Cow Dung Rd, stopping at Kissing Camels Ridge before continuing back to the Hab on Cow Dung Rd.

Mode of travel: Crew drove rovers to the collection sites and walked a small area on foot to collect specimens.

EVA # 1

Author: Jen Carver-Hunter

Purpose of EVA: Geologic sample collection

Start time: 11:30

End time: 12:15

Narrative: Loren, Enrique, and Jason were prepped and ready for the EVA on time. Perseverance dropped battery to 75% before the EVA team left the Hab, so they switched out Perseverance for another rover. Before the EVA team reached the halfway point to the first EVA destination, Curiosity had dropped to 60% battery. Crew was instructed to return to the Hab per protocols. EVA Team returned to the Hab with no other issues.

Destination: Intended destination: Intersection with Brahe Hwy followed by mounds near the balancing rock south of dry creek wash. Actual turn around point was near Galileo Rd.

Coordinates (use UTM WGS 84): (Intended coordinates: 518000, 4254750 and 518000, 4254000) Actual turn around point: 519000, 4252000

Participants: Loren Scott, Enrique Arce-Larreta, Jason Trump

Road(s) and routes per MDRS Map: Crew took rovers from the Hab to Cow Dung Rd, turned north onto Cow Dung Rd, and followed that what became their turn around point just south of Galileo Rd.

Mode of travel: Crew drove rovers to the turnaround point.
