EVA # 12
Author: Cristina Vazquez Reynel, Crew Exec Officer and HSO
Purpose of EVA: Experiment with robot Lazarus
Start time: 2:10 pm
End time: 4:10 pm
Narrative: The crew left the main Hab at 2:10pm with the robot and tested 3 times the same straight path of 12m with the intention of comparing the end coordinates recognised by the visual odometry. After that, they left the equipment at the airlock for the team in the Hab to download the data and recharge the battery. Meanwhile, Paula and Cristina took a walk around the station exploring the area. Once the robot was ready to test again, they collected it and tested 3 times a square path of 10m. The data was downloaded from the robot and will be analyzed.

EVA # 11
Author: Laurène Delsupexhe – Crew Engineer
Purpose of EVA: Testing of the Dronomy robot + Explore the surroundings of the Hab.
Start time: 2:10 pm
End time: 4:30 pm
Narrative: After double-checking the 2 suits were fully charged, the EVA crew waited for a final confirmation from Mission Support. Once they had it, they left the hab to reach an area east of the Marble’s Ritual, quite flat and less windy, where they set up the experiment of the Dronomy robot. The testing went well and the robot responded as predicted. The data was collected but the memory was full a little earlier than predicted. Once finished with the experiment, the EVA Crew headed back to the station to drop off in the airlock the robot and the necessary instruments. They then headed back north of the station, aiming for a hill north of the Marble’s ritual. Some photos were taken and soil was collected. The crew then headed back home, tired but satisfied

EVA # 9

Author: Laude

Purpose of EVA: Social media filming by the Crew Journalist.

Start time: 0900
End time: 1140

Narrative: We made our way on foot to the base of Phobos Peak taking photos and videos along the way. Many interesting rock and sediment formations were seen with all displaying the forces of erosion likely by weather and water. We readily hiked a short way up to its southern slope and stopped at a nice nearly flat overlook, but could not view MDRS.

We then descended to the base and walked partway around the base looking for another perch. Finding none, we rehiked up to the previous overlook where Treadwell continued her work. We stayed there for about 40 minutes until she got everything she could think of and several minutes longer as Laude was reluctant to leave such an awesome view and time was on our side.

Finally, we made good speed and arrived at the hab 20 minutes early.

Destination: Phobos Peak

EVA # 10

Author: Levesque

Purpose of EVA: Long-range communications testing

Start time: 1300
End time: 1600

Narrative: The EVA team drove to Zubrin’s Head and then proceeded on foot to a point 500 meters west for a comms check. They returned to the rovers and drove down the road to repeat the process on foot on a road near White Rock Reservoir and later in White Rock Canyon to the south. They next drove back to the junction of Cow Dung Road and a rough road leading to Barrainca Butte and walked on foot from there to conduct two comm checks along that road. After completing all checks, they returned to the rovers and drove back to the Hab, having to stop twice because of a rover’s overheating.

EVA # 6

Author: Laude

Purpose of EVA: To conduct more distant communications project testing, examine possibility of rover travel to the north of Moon Overlook, map areas of interest and to simulate a first Phobos manned mission from Mars and perhaps from anywhere. The crew will collect limited regolith samples and small rocks, plenty of photos and explore on foot in nearby areas that warrant closer examination. Also, we will look south from Moon Overlook to view the condition of Copernicus Highway for a possible future rover EVA.

Start time: 12:30

End time: 16:25

Narrative: We got off on time and traveled to Moon Overlook stopping along the way for radio checks. At the overlook we looked south to see the condition of Copernicus Highway leading south for another day EVA down that road. Conditions looked good for rover travel. We took photos at the overlook of the marvelous moon like terrain below us and to the north and then we descended down into it by rover. After a few hundred meters we stopped to collect a regolith sample with a scoop from Phobos, set some footprints and get photos. As we continued by rover the scenery quickly shifted to more Mars like as Phobos is tiny in size. Red canyon walls with stratigraphic layers enveloped us, opening up and closing in as we proceeded. At one open area we came across remnants of a fence that we passed through and soon the path became sandy and the rovers squirmed about from time to time. Shortly after coming across Muddy Creek the path narrowed and the sand loosened around our wheels. We might soon need 4WD to proceed if not for the decision to stop for a better look and turn around. The two rovers did need 4WD briefly to turn about. On the way out Laude decided to stop where there was a shallow slope up to a higher point (8M) to better view the area on foot. When looking down during ascent he noticed sea shells by the thousands (crew named it the Sea of Shells 4255097 N 516370 E)! Dense collections of them on the hill side. After calling the crew to see them he walked higher and noticed many other nearby hills covered with them! This area may warrant closer examination during a future EVA. After this unexpected find the crew returned back to MDRS.

Destination: Moon Overlook then north to the end of the drivable Copernicus highway.

Coordinates (use UTM NAD27 CONUS): 4254360 N, 516052 E (Moon Overlook) 4257885 N, 518294 E (End of passible road on rover near Muddy Creek. Dirt road turned sandy and narrow there.)

EVA # 7

Author: Laude

Purpose of EVA: To conduct remote communications project testing.

Start time: 12:00

End time: 16:20

Narrative: We left Percy at the junction of Lith Canyon and Cow Dung Roads as it was down in charge more than Spirit and Curri and then proceeded to the Green Mars View overlook for radio testing. Just several plants were along the wheel tracks. The ground below us where the Muddy River runs was thick with vegetation from the creek up to the base of the escarpments. We then traveled back passing Percy to end up on rover to near the end of Lith Canyon Rd. We hiked about for a couple hours with variations in elevation for more radio testing. All prescribed radio tests were completed and then we headed back to the hab picking up Percy on the way.

Destination: Green Mars View. Lith Canyon area.

Coordinates (use UTM NAD27 CONUS): (4256658 N, 520662 E). (4256474 N, 518949 E) .

EVA # 5

Author: Levesque

Purpose of EVA: Communications testing and road condition evaluation.

Start time: 0930

End time: 1345

Narrative: The EVA team drove along Cow Dung Road testing radio communications along the way using the project radios via the repeater on North Ridge and a simplex MDRS channel. Upon parking the rovers at the entrance to the dinosaur quarry, the team proceeded on foot down into Lith Canyon. During their trek along the canyon floor and its south rim, several communication checks were made with the Hab to test the project repeater and the MDRS radio channel. Radio contacts continued on the project radios via the repeater, but none were achieved on the simplex MDRS channel because of the terrain. It wasn’t until the team reached a high point on the south rim that contact was re-established on the MDRS channel, where line of sight communications could be obtained. After completing the testing, the team returned to the rovers and traveled back to the Hab. About a mile from the Hab, the Opportunity rover overheated and had to stop for 10 minutes before proceeding. It did so again just short of its parking space in front of the station and had to be pushed to its recharge station.

Destination: Lith Canyon

Coordinates: UTM NAD27 CONUS 0518270 4256052

EVA Participants: Levesque, Iakymov, Blanco

Road(s) and Routes per MDRS map: Cow Dung Road to Quarry Road and return.

EVA # 3

Author: Levesque

Purpose of EVA: Conduct communications testing to the south of the Hab.

Start time: 0930
End time: 1145

Narrative: The team proceeded south from the Hab on Spirit and Perseverance to Kissing Camel Ridge, where it conducted its first radio check. From there, the crew split into two teams on foot, with two members proceeding on the south side of the West Ridge, and two headings on the south side of the East Ridge. While on foot, the teams conducted radio checks on both the repeater frequency and on a Hab frequency to test the ability of both to contact the Hab. GPS locations of these checks were captured by the HabCom in a log for later mapping. Both teams then returned to their rovers and continued south to Zubrin’s Head as the final check of the communications test before returning to the Hab.

Destination: Kissing Camel Ridge East and West and Zubrin’s Head
