Crew 227 EVA Report 3rd April 2022
SOL: 7
Name of person filing report: Jean Jacobs

Purpose of EVA: Further exploration of the Tank wash starting at Cow Dung Road

Start time: 9:00

End time: 12:00

Narrative: The team drove up 500m North of reservoir Dam on Cow Dung Road and parked the rovers in front of the beginning of Tank wash as did yesterday’s team. Then they entered the wash and directly went as far as they could. They were able to reach 425500 N; 520750 E a pillar rock in the middle of the canyon about 2.5 km within. We fired up the drone to take pictures for future 3D modeling. The canyon layers seemed like sheets of rocks making it look like a book on the side. Unfortunately, the picture taken lacked the GPS coordinate to make a 3D map of the canyon making it impossible to map the canyon.

Despite a cloudy morning, we did not have any rain.

Destination: Tank wash North East of Cow Dung road

Coordinates: 425500 N; 520750 E

Participants: Jean, Cyril, Sirga, Julie, Cheyenne

Roads and routes per MDRS map: Cow Dung Road 0110

Mode of travel: Rovers Spirit, Opportunity and Curiosity

Purpose of EVA: Exploration of the Tank wash starting at Cow Dung Road
Start time: 9:25
End time: 13:00

Narrative: The team drove up 500m North of Reservoir Dam on Cow Dung Road and parked the rovers in front of the beginning of Tank wash (It took them a few minutes to find the entry of the tank wash).

On the way down, the wash, they took pictures of the vegetation and peculiar features. Due to time constraints, they were able to reach half of the wash and had to come back.

Despite the inability to reach the end of the wash, the exploration was a partial success with pictures of the area and vegetation taken.

EVA # 22

Author: Nicolas WATTELLE

Purpose of EVA: Dismounting of our outdoor experiments’ devices

Start time: 9:32

End time: 10:27

Narrative:

EVA participants checked the rover batteries just in case. The obtained information is:

Perseverance: Usage Duration – 228.6 Battery Charge – 100%

Spirit: Usage Duration – 157.7 Battery Charge – 100%

Opportunity: Usage Duration – 87.1 Battery Charge – 100%

Curiosity: Usage Duration – 171.1 Battery Charge – 100%

Nicolas, Marine, Elena and Matheo went to the atmospheric experiment location by rover. They arrived at 9:40. They dismounted the different devices, and brought them back to the Hab, using rovers, at 9:57.

Cerise the Habcom, after depressurization, took the devices inside the Hab.

Then, by foot, Nicolas, Elena, Marine and Matheo went to the antenna location. There, they dismounted the antenna.

They were back at the airlock with the instrument at 10:22.

Depressurization ended at 10:27.

Destination: Intersection between Cow Dung Road and Entrance Road. The atmospheric experiment devices are set up in a circle of radius 2 m. Behind the Hab, where the antenna is set.

Coordinates (use UTM NAD27 CONUS): 518288 E, 4250586 N

Participants : Nicolas Wattelle (EVA Leader), Mathéo Fouchet, Marine Prunier, Elena Contreras.

Crew 263 EVA 20 Report 09-03-2022

EVA # 20

Author: Cerise Cuny

Purpose of EVA: Replacing the batteries for the atmospheric experiments, a second analysis of sulfate deposits using a handheld LIBS (Laser-Induced Breakdown Spectroscopy) analyser.

Start time: 08:09 am
End time: 12:19 pm

Narrative: We first checked the rovers’ batteries and usage duration, then drove with Opportunity (86.3h and 100%) and Curiosity (170.3h and 100%) to the atmospheric experiment site. Changing the batteries took only 5 minutes this time, everything went well. At 8:25 we left for Candor Chasma.

As planned, we stopped at the intersection of Galileo Road and Streambed connector at 8:40 (Opportunity 86% and Curiosity 88%). From there, the canyon was reached by foot. We found our path very easily thanks to the very precise instructions and pictures of yesterday’s EVA team.

Inside the canyon, we made several stops to proceed on pictures and LIBS analysis. We took a sampling of what we thought was a nodule for further analysis at the station. The drone was quite useful to evaluate which arms of the canyon were accessible by foot. We were able to reach outcrops that wouldn’t be reachable by a Martian rover.

We also tried to use it to spot interesting outcrops but at some point, the Summerville formation was everywhere around us, so it was easy to find relevant outcrops with our own eyes.

At 11:11, we u-turned and reached the rovers at 11:50, with several breaks to catch our breath. Elena’s suit went out of battery at 11:15 during our return, she struggled a bit with fog in the helmet. We entered the AirLock at 12:19 for depressurisation.

Opportunity: Usage Duration – 86.7 Battery Charge – 81%

Curiosity: Usage Duration – 170.7 Battery Charge – 81%

Destination: Zone G -final expected point of interest is located at coordinate 4251533.157 N 521043.495 E.

Participants: Cerise Cuny (EVA leader), Nicolas Wattelle, Mathéo Fouchet, Elena Lopez-Contreras Gonzalez

Road(s) and routes per MDRS Map: Entrance Road, Cow Dung Road, Galileo Road 1104.

Mode of travel: Rover for battery change and then until the entrance of Candor Chasma, By Foot in Candor Chasma.

Vehicles you will be using (If applicable): Curiosity, Opportunity

Crew 263 EVA 18 Report 08-03-2022

EVA # 19

Author: Marine Prunier

Purpose of EVA: Replacing the batteries for the atmospheric experiments, Analysis of sulfate deposits using a handheld LIBS (Laser-Induced Breakdown Spectroscopy) analyzer.

Start time: 08:12

End time: 12:34

Narrative: EVA Participants entered the airlock at 08:12. Depressurization ended at 08:17. EVA participants checked the rover batteries. The obtained information is:

Perseverance: Usage Duration – 228.1 Battery Charge – 100%

Spirit: Usage Duration – 157.7 Battery Charge – 100%

Opportunity: Usage Duration – 85.8 Battery Charge – 100%

Curiosity: Usage Duration – 169.9 Battery Charge – 100%

The EVA participants took Opportunity and Curiosity at 08:17 and drove on Entrance Road until Cow Dung Road. Batteries of the Atmospheric Experiments -LOAC, Mega-Ares, Purple Air- were replaced. The old batteries were placed on the rover trunks (08:40).

The participants drove on Cow Dung Road to the southern end of Galileo Road 1104 towards Candor Chasma. From there, the canyon was reached by foot. The EVA participants took about one hour to find the entrance of the canyon. Their GPS went out of battery at the beginning of the EVA, and they took the wrong direction. The correct path to the canyon was finally found and was documented with notes and pictures for a potential other EVA in this area.

Inside the canyon, the participants made several stops to proceed on sketches and pictures. A software issue with the LIBS analyzer prevented the participants to use it on the field, therefore several samples of rocks have been taken for further analysis at the station.

At 11:13, the participants left the point of interest inside the Canyon. At 11:55 they reached the rovers parked on Galileo Road. They arrived back near the Atmospheric Experiments at 12:07 and stopped there for 15 minutes to extract data from Mega-Ares. They drove back to the Hab at 12:27.

Opportunity: Usage Duration – 86.3 Battery Charge – 77%

Curiosity: Usage Duration – 170.3 Battery Charge – 76%

They entered Airlock and at 12:34 the pressurization was over.

Destination: Zone G -final expected point of interest is located at coordinate 4251533.157 N 521043.495 E.

Participants: Marine Prunier (EVA leader), Léa Rouverand, Valentine Bourgeois. HabCom was Cerise Cuny.

Elena Lopez-Contreras was supposed to participate to the EVA, but she woke up feeling tired and decided that it would be safer to stay at the Hab and have some rest.

Road(s) and routes per MDRS Map: Entrance Road, Cow Dung Road, Galileo Road 1104.

Mode of travel: Rover for battery change and then until the entrance of Candor Chasma, By Foot in Candor Chasma.
