Crew 314 EVA Report 10-04-2025

EVA #6

Author : Odile Hilgers

Purpose of EVA: The primary objective of tomorrow’s EVA is to conduct essential equipment checks at the intersection of Galileo Road and Cow Dung Road. Subsequently, we will discover some new area, known as Candor Chasma. We will park our rovers at Compass Rock, and walk from this point. The goal of the walk is to enter the canyon and advance approximately one mile beyond the rover parking point to conduct further observation and terrain assessment.

Start time: 9:32 am

End time : 11:12 am

Narrative :

Minor change in this morning’s EVA crew: Batoul Tani had a scientific emergency related to her own experiment and couldn’t participate in the EVA.

The crew left the Hab on time this morning. The team was split in two, with Arnaud acting as EVA leader for the day. He took Curiosity, while Béatrice and Antoine took Opportunity (Spirit is still out of use due to a battery charging issue, which explains the change from yesterday’s EVA plan). Béatrice was driving.

They made a first stop at the intersection of Galileo Road and Cow Dung Road, after taking Moonwalk Road out of the MDRS. They checked Antoine’s equipment—no issues to report.

They continued to Compass Rock, where they planned to leave their rovers for the day. At one point, there was a brief concern due to a miscommunication: Mission Support thought the EVA team might be stuck somewhere. Fortunately, the situation was quickly clarified, and the mission could proceed.

The team made a brief stop along Galileo Road without leaving the rover. CapCom and the EVA leader attempted to communicate, but the signal was very poor. A change in leadership was made, with Béatrice becoming the new EVA leader.

Their actual position differed from the one initially planned, so they proceeded a bit further and finally reached Compass Rock at 10:15. There, they discussed the map and the route they would follow through the canyon, and left the rover at 10:25.

Due to very poor signal in Candor Chasma, we had no contact with the EVA team while they were walking.

They reestablished communication with CapCom at 10:53, informing us they were exiting the canyon.

On the way back, Antoine drove Curiosity solo, while Arnaud drove Opportunity with Béatrice as passenger. They returned safely to the Hab and even had the chance to admire some lizards along the way.

EVA # 7

Author: Béatrice Hollander (Crew Commander)

Purpose of EVA: The crew will travel between two locations to collect different soil samples for the GreenHab. Bérengère will examine the soil composition, specifically looking for the presence of fungi. On the way back, they’ll stop at the intersection of Galileo Road and Cow Dung Road to check Antoine’s equipment.

Start time: 9h26

End time: 11h47

Narrative:

The crew left the Hab on time this morning. After a 5-minute decompression, the EVA team exited the airlock at 9:31. Batoul was at the wheel of Curiosity, with Odile as her passenger, while Bérengère drove Opportunity, accompanied by Antoine.

At 9:42, they drove past Cowboy Corner, continuing smoothly toward their first destination. Just before reaching the Special Region, around 9:55, they made a stop to confirm their path and attempted to contact CapCom for guidance. However, the signal was very poor at that point, and they were unable to establish communication.

Fortunately, upon arrival at the Special Region around 10:05, the signal improved. There, the team took the opportunity to collect two soil samples for Bérengère’s experiment.

At 10:47, the team decided to head back to the rovers to proceed to their next waypoint, staying mindful of the time and battery levels. By 10:59, they reached the intersection of Brahe and Cow Dung Road. With Opportunity’s battery at 58%, they made the decision to skip the Overlook and continue directly to the intersection of Cow Dung and Galileo Road.

On the way, the team made a quick stop to retrieve a piece of the camera that had fallen from one of the rovers. They then continued to their planned stop at the intersection of Galileo Road and Cow Dung Road to inspect Antoine’s equipment, which had been left there for his experiment, arriving at 11:15. With the extra time saved from skipping the Overlook point, they chose to deploy the drone for additional data collection.

By 11:34, they began their return journey to the Hab, with a switch in drivers: Odile took over Curiosity with Batoul as passenger, while Antoine drove Opportunity, this time with Bérengère as his passenger.

The rovers were parked back at the MDRS at 11:41, and the team collected their data. Decompression began at 11:42 and was completed by 11:47, successfully concluding the EVA.

Destination: The furthest point of the EVA is the Special Region, near Gateway Lith, then they will head west to make a second major stop at Overlook.

Coordinates (use UTM WGS 84):

First stop : Special region (518500N, 4256000W)

Second stop : Overlook, at the intersection of Brahe Hwy 1572 and Copernic US Hwy 1575 (516000N, 4254500W).

Third stop : Intersection Galileo Road and Cow Dung Road (4252250N, 519000W)

Participants: Batoul Tani (Journalist), Antoine Dubois (Engineer), Bérengère Bastogne (Greenhab), Odile Hilgers (HSO)

Road(s) and routes per MDRS Map: The crew went on Moonwalk Road, then continued on Cow Dung Road 0110. From there, they took the road leading to the Special Region. After reaching this point, they took Brahe Highway 1572 toward Overlook. Finally, they returned to the MDRS via Cow Dung Road 0110.

Mode of travel: Driving and walking

EVA # 8
Author: Bérengère Bastogne (Greenhab Officer)
Purpose of EVA: We will head to the Sea of Shells where we will conduct a drone exploration and use the hammer to search for fossils. On the return journey, we will also stop at the intersection of Galileo Road and Cow Dung Road to inspect Antoine’s equipment.
At those two stops, the crew will stay within 1 mile from the rovers.
Destination: The furthest point of the EVA will be the Sea of Shells. We will then head back at the MDRS to make a second stop at the intersection of Galileo and Cow Dung Road.
Start time: 9:30am
End time: 11:32am
Narrative:
Today’s EVA was carried out under hotter weather conditions compared to previous sols and some wind (around 15mph wind gusts). The crew departed the Hab at 09:44 with two rovers, heading toward the Sea Shells region to continue geological sampling.
At 09:52, the team passed Cowboy Corner and reached the intersection with Brahe Highway at approximately 10:00. At that point, the communication signal was extremely weak, and the team was unable to establish contact with CapCom.
By 10:10, the EVA team arrived at the Sea Shells site. Although the signal improved briefly, the area’s terrain quickly descended, resulting in another loss of signal. The team proceeded with their sampling task despite this challenge.
At 10:27, wind conditions were recorded: gusts reaching 16 mph with a steady wind of 4 mph coming from the west. The crew completed their work and began the return to the rovers at 10:56, but they were not able to fly the drone given the high winds.
They reached Brahe Highway again at 11:01, where communication was re-established. By 11:07, they returned to Cow Dung Road. A driver switch took place: Odile and Béa took over for the next leg of the journey.
The crew arrived at the site of Antoine’s experiment at 11:16 to perform a brief inspection. After a short stop, they returned to the rovers at 11:20 and switched drivers once again, this time Louis and Béa taking the wheel.
The EVA concluded with the rovers returning to the MDRS at 11:24. Decompression procedures were initiated immediately upon arrival and completed by 11:32.
This EVA allowed for critical fieldwork in multiple locations despite some signal challenges. The efficient management of time and logistics ensured the mission goals were achieved safely and effectively.
Destination: The furthest point of the EVA will be the Sea of Shells. We will then head back at the MDRS to make a second stop at the intersection of Galileo and Cow Dung Road.
Coordinates (use UTM WGS 84):
First stop : Sea of Shells (4255500N,516500W)
Second stop : Intersection Galileo Road and Cow Dung Road (4252250N, 519000W)
Participants: Antoine Dubois (Engineer), Béatrice Hollander (Commander), Odile Hilgers (HSO), Louis Baltus (Astronomer)
Road(s) and routes per MDRS Map: The EVA will begin on Moonwalk Road, then proceed along Cow Dung Road 0110. From there, we will follow Brahe Highway to the Overlook, and then take Copernicus 1575 Highway to reach the Sea of Shells. For the return trip to the MDRS, we will retrace the same route in reverse.
Mode of travel: Driving and walking

EVA # 9

Author : Odile Hilgers

Purpose of EVA : Driving to the Sea of Shells to get some soils for Berengère’s experiment, and on the way back, stopping at the intersection of Galileo Road and Cow Dung Road to check Antoine’s equipment.

Start time : 9:32am

End time : 11:50am

Narrative :

Four crew members participated in today’s EVA. Among them was our GreenHab Officer, Bérengère Bastogne, who is currently conducting an experiment involving fungi and requires soil samples from various Martian locations. Today, she collected a sample from the Sea of Shells, a place where an ancient ocean once lay—now long gone. Yet, if one lets their imagination wander, it is still possible to envision waves dancing gently in the wind. Joining her was Antoine, our Crew Engineer, who needed to verify whether his installation had withstood the violent winds from the previous day.

After donning their suits and completing the standard five-minute decompression, the crew exited the MDRS at 09:37. They split into two teams: Béatrice drove Opportunity with Antoine as her passenger, while Bérengère drove Curiosity with Arnaud—today’s EVA leader—riding as her passenger. Shortly after departure, Mission Support informed us that the crew was driving a bit too fast and reminded them to reduce their speed in order to conserve the rovers’ battery life.

At 09:42, the crew made contact to report that they had reached the intersection of Galileo Road and Cow Dung Road. At 09:53, they turned left onto Brahe Highway, and at 09:57, they checked in again to determine their distance from the intersection with Copernicus Highway—they were approximately 250 meters away (about 0.15 miles).

No further radio contact was made after that point; however, the crew’s position was continuously tracked via GPS. They arrived near their intended destination at 10:20 and began exploring the surrounding area, collecting two soil samples for Bérengère’s experiment. Concerned about Opportunity’s battery level—down to 57%—they decided to park the rover slightly earlier than initially planned. They also deployed the drone to capture aerial photographs of the canyon.

The crew left the Sea of Shells at 11:20. They attempted to contact CapCom at 11:26, but the signal was very weak, and no communication was possible until 11:40.

At 11:40, they reached the intersection of Cow Dung Road and Galileo Road, where they checked Antoine’s equipment. They briefly reported their activities : Antoine drove Opportunity until they reached Galileo Road, after which Béatrice resumed driving. Arnaud remained the driver of Curiosity for the entire return trip.

Destination : Sea of Shells (4256500N, 517000W)

Coordinates (use UTM WGS 84):

First stop : Sea of Shells (4256500N, 517000W)

EVA #10

Author: Béatrice Hollander (Commander)

Purpose of EVA: The crew will support Louis’s research, which began on Sol 4 inside the MDRS and will continue in the field on Sol 8, focusing on the interaction between humans and technology. For this, he requires an area with minimal wind so the crew can repeat a series of movements captured by a wrist-mounted portable device. The chosen location is the intersection of Cow Dung Road and Galileo Road.

Start time: 9:32 am

End time: 10:55 am

Narrative :

The EVA team began the decompression procedures in the airlock at 9:32 AM. The actual exit from the station occurred at 9:37 AM. Two rovers were used for this mission: Spirit, driven by Batoul with Arnaud as passenger, and Curiosity, driven by Odile with Louis as passenger.

The journey to the mission site went smoothly, and the team arrived at their destination at 9:47 AM. After spending time completing the mission objectives, which involved collecting movement data for Louis’s experiment for each crew member, the crew informed CapCom at 10:40 AM that they would be leaving the area within the next two minutes. The actual departure took place at 10:42 a.m.

The return to the station was also carried out without issue. Arrival at the station was recorded at 10:48 AM, immediately followed by entry into the airlock and the start of the recompression at 10:50 AM. Recompression ended at 10:55 AM, officially marking the end of the EVA.

The entire mission was conducted under good conditions, with good adherence to procedures.

Purpose of EVA: The aim of this EVA was to identify and evaluate a new measurement site for Antoine’s science experiment. After leaving the station, the crew headed north on foot around the science dome to explore a potential site. The purpose of this site evaluation was to determine whether the area presented the conditions required for collecting data on movements or environmental variables essential to Antoine’s research. The EVA also included a traverse of the rover to Green Mars View, which enabled the team to recover soil samples for Bérengère’s experiment.

Start time: 9:34 a.m.

End time: 12:15 p.m.

Narrative:

The EVA team began decompression procedures at 9:34 AM, with the process completed by 9:39 AM. At 9:40 AM, the crew started walking, contouring the Science Dome to head north in search of a new measurement site for Antoine’s experiment.

At 9:53 AM, the team stopped and began setting up equipment at coordinates 425100, 518000 (Utah region). The setup phase concluded at 10:20 AM, after which the crew returned to the rovers.

At 10:27 AM, Curiosity rover was driven by Antoine, with Odile as passenger, while Perseverance was driven by Béa, with Bérengère as passenger.

At 10:46 AM, the team made a short stop in a special region to establish communications before continuing on the road toward Green View.

At 11:48 AM, the crew left Green View to return to the station. This time, Odile drove Curiosity with Antoine as passenger, and Bérengère drove Perseverance, with Béa as passenger.

EVA # 15

Author: Odile Hilgers

Purpose of EVA: We will head to Green Mars View to collect soil samples for Bérengère’s experiment, as she wasn’t able to go today and still has a significant amount of work to complete tomorrow in the Science Dome. Once we return to the station, we will proceed to remove Antoine’s experiment equipment.

Start time: 09:02 am

End time: 11:06 am

Narrative:

The EVA team began their mission at 9:11 AM, departing from the MDRS with two rovers. Béatrice piloted Curiosity with Antoine as her passenger, while Louis drove Perseverance accompanied by Arnaud. Driving to their primary destination, the team passed through the Special Region at 9:25 AM without stopping.

By 9:48 AM, the team reached Green Mars View. There, they successfully collected soil samples for Bérengère’s experiment, which aims to study microbial content and soil characteristics relevant to greenhouse sustainability on Mars. The team worked efficiently, completing the sampling process and preparing for their return journey by 10:20 AM. On the return leg, rover drivers were rotated: Arnaud took over Perseverance with Louis as passenger, and Antoine drove Curiosity with Béatrice.

The team arrived back at the MDRS at 10:45 AM. Upon arrival, they promptly contacted CapCom to provide a full update, including mission timing and rover battery usage data. At 10:49 AM, the crew proceeded on foot to Antoine’s experimental site to dismantle the equipment and, at 10:58 AM, transport it back to the station, marking the conclusion of this phase of his research. They entered the MDRS at 11:01, and completed their 5 minutes decompression.

The EVA concluded successfully, with all objectives met and the team safely returned to the habitat.

EVA : #2

Author: David Laude

Purpose of EVA: Required practice/trial EVA to Marble Ritual by rover and then walk the area to check backpack fitting.

Start time for EVA : 3:03 pm

End time for EVA: 3:59 pm

Narrative: We got suited up and I tried a two piece suit and found it to have a heaviness on my lower back area so went with my usual #7 one piece. All seemed well then except for difficulty finding the radio transmit key when needed even though in a convenient location. We’ll have to find a better way to find it, maybe by placing it at the base of an easily found antenna. We walked to Marble Ritual placing stones in it and brief walk in area before returning to base.

Coordinates (use UTM WSG 84): 4250800N, 518750W

EVA Participants : David Laude (Commander), Tim Gagnon (Artist)

Road(s) and routes per MDRS Map: The EVA will begin on Moonwalk Road, then proceed along Cow Dung Road 0110 to Marble Ritual.

Crew 315 EVA Report 21-04-2025

EVA # 1

Author: Michael Andrews, Crew Engineer

Purpose of EVA: To familiarize the crew with EVA operations and perform the Marble Ritual: collecting a rock in the surrounding area and depositing it into one of the three baskets at the site.

Start time: 1300

End time: 1345

Narrative:

The EVA crew put on their space suits for the first time, quickly learning the difference in weight and comfort between the single-piece and two-piece suits. During our depressurization window, the Commander played us the main song from 2001: A Space Odyssey to get excited. We opened up the hatch and Crew Journalist Saavedra-Buckley set foot on the red planet first for our mission.

The team traveled via rovers (Saavedra-Buckley leading in Perseverance, Andrews and Koi in Curiosity) to Cow Dung Road and headed north approximately one kilometer. We attempted to communicate with CapCom via Channel 1, but we were too close to the station and opted for Channel 2 instead. The crew each found their own rocks and deposited them in the red, green, and blue baskets to complete the Marble Ritual.

The crew still had about 30 minutes left in the EVA window, so we continued east to get used to the terrain and take photos of the environment and crew. We returned to our rovers at 1335 and headed back to the Hab via Cow Dung Road. After a quick photo at the entrance to the Hab, the crew returned to repressurize. The EVA ended at 1345 with no issues or unaccomplished objectives.

Destination: Marble Ritual

Coordinates: Easting 518750, Northing 4251000

Participants: Michael Andrews (EVA Lead and Crew Engineer), Urban Koi (Health and Safety Officer), Elena Saavedra-Buckley (Crew Artist)

Road(s) and routes per MDRS Map: Traveled east to Cow Dung Road via rover, then north via Cow Dung Road via rover. The crew parked on the east half of the road and traveled to Marble Ritual on foot. After performing the ritual, the crew took a counterclockwise loop east of Marble Ritual to further explore the area and take photos.

Mode of travel: Rovers from Hab to Marble Ritual (Perseverance and Curiosity), followed by traveling on foot.
