Crew 235 EVA Report 05 May 2021

EVA # 4, 5

Author: Jen Carver-Hunter

Purpose of EVA: Continuation of rock sample collection

EVA 4 Start time: 0900

EVA 4 End time: 1000

EVA 5 Start Time: 1200

EVA 5 End time: 1430

Narrative: One of our crew’s goals is to collect rock samples that replicate the rocks found on Mars. For today’s EVA, our targeted specimens were lava, basalt, and granite. In addition, we developed a scavenger hunt challenge for the two EVA crews to use as a competition that included specimens of gryphaea, purple lava, hematite, and sandstone blueberries.

The first planned stop for the EVA was the route to Barainca Butte, and the second planned stop on return to the Hab was east of Zubrin’s head.

The first EVA crew left the hab in vehicles at 0900 and followed Cow Dung Road south to Road 1101. After following Road 1101 west toward Barainca Butte, the crew stopped to collect rock samples, which included lava, granite, and basalt, and gryphaea. The Commander’s suit battery discharged so the EVA was aborted and the crew returned to the hab at 1000.

Because that crew’s EVA mission was not completed they requested that the second EVA crew collect extra samples to meet the day’s goals. They also requested that the second crew return some unwanted petrified wood samples to the west side of Kissing Camel Ridge, as was suggested by Dr. Rupert when she approved today’s EVA last night. Due to the dead battery in Spacesuit 7, the second EVA was only able to accommodate 3 crew members. Krysta volunteered to stay at the hab and requested that her crewmates bring samples back for her collection.

The second EVA crew left the hab in vehicles at 1200 and also followed Cow Dung Road south to Road 1101. They followed Road 1101 toward Barainca Butte and collected their samples along the road. After collecting on Road 1101, the EVA team turned around and turned north on Cow Dung Road until they reached “the Squirrel” landmark. They followed a wash to the west (they were east of Zubrin’s head) until they found the sandstone blueberry nursery.

At this point, they were able to complete the second objective of their mission. The final objective was to return the pieces of petrified wood they were done using to their collection site. Crew stopped south of Kissing Camels Ridge and walked west to return their samples before returning back to the Hab. The second EVA crew returned to the Hab with no difficulty and shared their collected samples with the first EVA crew.

Purpose of EVA: Specimen collection

EVA 2 Start time: 10:00

EVA 2 End time: 12:00

EVA 3 Start Time: 12:00

EVA 3 End time: 1:30

Narrative: One of our crew’s goals is to collect rock samples that replicate the rocks found on Mars. For today’s EVA, our targeted specimen was petrified wood, which we are using as an analogous specimen for the hematite found on Mars. Because Kissing Camel Ridge has an excellent source of petrified wood, we chose that location for our EVA.

The crew left the hab in vehicles and followed the road south to Kissing Camel Ridge. Crew walked to the southwest side of Cow Dung Road and followed the wash to the west along the ridge. Crew continued along the wash to the source of the petrified wood specimens in the wash. The crew on EVA 2 found a location that they thought might be the source Dr Rupert mentioned. It looked like someone had piled up mounds of petrified wood.

EVA # 12

Author: Alex Coultrup, Health and Safety Officer

Purpose of EVA: Final survey for emergency shelters and soil samples

Start time: 1015 MDT

End time: 1215 MDT (planned 1300, actual 1200)

Narrative: The EVA this morning started 15 minutes after the scheduled EVA window opened, as the crew had carefully gathered and sterilized required scientific instruments to meet Planetary Protection Protocols. After suiting up, the crew waited 5 minutes before exiting the airlock. The EVA crew departed from the Hab/Hab Grounds by foot, heading northwest. We rapidly identified the ATV road (1103) and followed it north, then west as it curved just before North Ridge, keeping an eye out for potential emergency shelter locations along the way. We followed the trail of GPS points left by the previous day’s EVA crew and demonstrated a successful navigation of our instruments.

After a thirty-minute hike, we reached the top of the western ridge stopping occasionally to drop more points and practice orienting our position with respect to both the GPS device and the map. We took soil samples along the ridge, then admired the view of North Ridge, Schubert’s Pass, and the western buttes. After determining there were no valid candidates for emergency sheltering, the team headed back along the 1103 route pointed out by the outpost as advice. The team managed a very quick return by foot to the Hab and was in the airlock just before 1200.

Destination: Schubert’s Pass

Participants: Health and Safety Officer Coultrup, Crew Scientist Ettlin

Road(s) and routes per MDRS Map: Walking up near a ridge slope by the Hab, taking 1103 walking back.

Mode of travel: Walking.

EVA # 10

Author: Crew Scientist Olivia Ettlin

Purpose of EVA: Gathering soil samples and scouting for emergency shelters.

Start time: 1015 MDT

End time: 1330 MDT

Narrative: The EVA this morning started slightly after the beginning of the approved EVA window, as the crew was carefully gathering and sterilizing required scientific instruments according to XO Hume’s Planetary Protection Protocols. After we suited up and completed our 5-minute decompression in the airlock, we loaded our supplies into the Perseverance rover. Commander Dickstein and Health and Safety Officer Coultrup drove the Rover and Crew Scientist Ettlin took the ATV Serial Number 2. Starting charge on the Rover was 100% with 204.1 hours and the ATV required some choke before starting.

We traveled from the Hab to Entrance Road and proceeded south on Cow Dung Road for approximately 10 minutes until we reached Zubrin’s Head. Upon arrival at Zubrin’s head, we parked our vehicles on the side of the road. Using the analog map, we confirmed that our travel calculations had been accurate. From there, we embarked southwest on foot to explore the immediate region and investigate points of interest, which were communicated to us by our crewmates after their EVA to this site. As always, we carried the EVA med kit with us.

When we had completed gathering the samples, we returned to our vehicles and proceeded north on Cow Dung Road to Robert’s Rock Garden, where we did a final visit to drop waypoints and collect rock samples. From there, we returned to our vehicles and proceeded to Entrance Road, where we paused for approximately 20 minutes to capture some memorable photos with the MDRS entrance sign and facility as a backdrop, as directed by Mars Society Media Director Michael Stoltz. Finally, we returned back to the Hab. Upon returning, the Rover displayed 204.6 hours and 100% charge.

Destination: Zubrin’s Head

Coordinates of Destination: 12S 519500 UTM 4248100

Participants: Crew Scientist Olivia Ettlin, Commander Dylan Dickstein, and Health and Safety Officer Alex Coultrup

Road(s) and routes per MDRS Map: Hab to Entrance Rd, then South on Cow Dung road to Zubrin’s Head. Cow Dung Road to Entrance Rd, then back to the Hab.

Mode of travel: 2 team members in Perseverance Rover, 1 team member following close behind on ATV serial #2. All three members of the team walked the destination from the location where we parked the rovers safely on the side of the road.

EVA Report – April 17th

Author: Julio A. Hernandez

Purpose of EVA: A training EVA to improve crew mapping abilities

Start time: 09:00

End time: 11:30

Narrative: The EVA this morning started exactly at the beginning of the approved EVA window. The crew took enhanced measures during the EVA debriefing to ensure that the EVA participants were well prepared for the mission. In short, the route was mapped and landmarks were identified to aid in navigation. The health and safety checks were conducted without any issue to note; the participants were engaged and eager for their EVAs. Crew Botanist Hernandez and Crew Engineer Hariharan were the driver and navigator in the Perseverance Rover, respectively. As per Outpost’s recommendation, ATV #2 was taken for the EVA by XO Hume. The starting charge of the Rover was 100% with 202.1 hours. The ATV started up after some difficulty due to a cold engine.

We proceeded toward our destination, Robert’s Rock Garden, following the Cow Dung Road, as shown on the map and per the pre-EVA briefing. The EVA team checked COMMs with HABCOM until they were out of range. The EVA team stopped on the north side of Robert’s Rock Garden and took a photo of Kissing Camel to the East. Phobos Peak was included in the photo.

After visiting Robert’s Rock Garden, the EVA team departed to Zubrin’s Head. Identifying Zubrin’s Head proved to be challenging. Using both the map, approximated GPS coordinates, and location of the Sun, the EVA team identified a feature that they believed to be Zubrin’s Head. As a precaution to ensure the identified geological feature was indeed Zubrin’s Head, the EVA team proceeded up and down Cow Dung Road to raise their confidence in their feature identification (the feature looks like a person wearing a hat?). The EVA team proceeded to take photos of themselves next to the structure.

The EVA team then proceeded to hike in a southwest direction to explore the area. Using a local small hill, the EVA team took photos of the Barrainca Butte. After this little excursion, the EVA team returned to their vehicles to relocate themselves to the south side of Robert’s Rock Garden to collect soil samples at four different locations before returning to HAB grounds. The EVA team was granted permission to re-enter the HAB ground by HABCOM. The vehicles were parked. The Rover was parked and 86% with 202.7 hours. The EVA team was granted permission to re-enter the HAB and the airlock was sealed and re-pressurized.

Destination: Robert’s Rock Garden, Robert’s Head, Barrainca Butte

Coordinates (use UTM NAD27 CONUS): Moving through 12 s 518250 utm 4249250 (Robert’s Rock Garden), parking at 12 s 519500 utm 4248100 (Robert’s Head), hiking to near 519000 4247000 (Barrainca Butte)

EVA # 7

Author: Health and Safety Officer Alex Coultrup

Purpose of EVA: Training and confirmation of orienteering skills and ability to navigate to specified destinations using analog maps.

Start time: 1230 MDT

End time: 1520 MDT

Narrative: The EVA this afternoon started right at the beginning of the approved EVA window. HSO performed our required health and safety checks (blood pressure, heart rate, and temperature checks) and carefully implemented our planetary protection measures as per XO Hume’s research protocol. After we suited up and completed our 5-minute decompression in the airlock, we loaded our supplies into the Perseverance rover. Commander Dickstein and Crew Scientist Ettlin drove the Rover and HSO Coultrup took the ATV Serial Number 2. Starting charge on the Rover was 89% with 202.8 hours and the ATV started up quickly with little choke needed.

We traveled from the Hab to Entrance Road, and pulled over to consult our map. By using the map to estimate the distance, and by estimating the speed of the rover, we were able to estimate the total expected time to travel between this location and our first destination. We resumed traveling north on Cow Dung Road for the duration we calculated, and arrived at Streambed Connector as anticipated. We parked the rovers safely on the side of the road. Using the same calculation techniques as before, we estimated the duration of our walk to Destination 1. Using the analog map, we walked to Destination 1, took a photo, and enjoyed the view of the beautiful rock strata to our north upon arrival. As always, we carried the EVA med kit with us for this walk. We returned back to the vehicles using the same route, and proceeded north on Cow Dung Road toward Destination 2.

While traveling toward Destination 2, we pulled over at Galileo Road to consult our map and ensure accurate navigation. After performing our time/distance calculations, we continued North along Cow Dung Road, and were able to visually determine when we passed Cowboy Corner. We continued slightly further down Cow Dung Road, safely parked the rovers, and walked a few hundred meters toward the reservoir area, where we captured a photo of our arrival. We returned back to the vehicles using the same route, and consulted our map to perform the same navigation process we had been employing so far. We determined the distance, speed, and rate of travel, and proceeded north on Cow Dung Road toward Destination 3.

As we approached toward Destination 3, we pulled at the end of our approximated travel duration, but by consulting the analog map and visual landmarks, we were able to determine that we were not yet at the desired location. We re-started our vehicles and proceeded 30 seconds further north, and reached the intersection of Tank Wash Road and Cow Dung Road. We took a photo facing west, and returned to our vehicles.

From Destination 3, we began travelling south on Cow Dung Road until we reached the Streambed Connector. At the Streambed Connector area, we pulled over once again and spent some time collecting soil samples for our scientific research. When we had completed gathering the samples, we returned to the vehicles and proceeded south on Cow Dung Road to Entrance Road, and back to the Hab. Upon returning, the Rover displayed 203.2 hours and 86% charge.

EVA Report – April 20th

Crew 245 EVA Report 20-04-2021

EVA #9

Author: Crew Engineer Shravan Hariharan

Purpose of EVA: Conduct soil sampling for astrobiology and geology studies (site was used in prior astrobiology studies that we are conducting follow-ups to), as well as emergency shelter identification and planetary protection experiments. We want to return to an original location for repeat sampling.

Start time: 1210 MDT

End time: 1530 MDT

Narrative: The EVA this afternoon began slightly after the start of the approved EVA window, as the team implemented a higher level of instrument sterilization and general cleanliness as per the XO’s planetary protection protocols. After spending five minutes in the airlock, the EVA team proceeded to their vehicles; the Executive Officer drove the Perseverance rover with the Commander navigating, and the Crew Engineer followed closely behind in ATV 1. Starting charge on the rover was 100% with 203.5 hours, and the ATV required some choke before starting.

The EVA team proceeded north on Cow Dung Road for approximately 20 minutes, until Quarry Road was reached. Communications contact with the Hab was lost approximately 2 km North of the Hab, as was expected based on experience from past EVAs. The EVA team parked vehicles by the edge of the Special Region, and proceeded on foot into Lith Canyon. The team’s first goal was to evaluate an emergency shelter identified on EVA #3, by first identifying the emergency shelter using relative location descriptions (i.e nearby landmarks and the general appearance of the shelter), and then classifying the shelter based on its utility to future crews in emergency situations. The team successfully identified and evaluated the shelter, although it was observed that the relative directions were somewhat unclear and should be modified to include precise cardinal directions of nearby landmarks. The EVA team then collected three soil samples from the streambed leading into the canyon, and marked the locations of each sample. Prior to proceeding into the canyon, the EVA team identified a second emergency shelter, and evaluated this shelter using the same qualitative criteria.

The EVA team then proceeded to enter Lith Canyon in order to scout for additional soil sampling sites. Upon exploration of the canyon floor, the ground was found to be too rocky and hard for subsurface soil sampling, so the team took several pictures of/in the site prior to returning to the vehicles. The EVA team then returned to the vehicles, and proceeded to drive back to the Hab. The vehicles were parked at the Hab, with the Perseverance rover at 241.1 hours and 84% charge. The team entered the airlock after permission was granted from Hab, and after five minutes of pressurization, the Hab was entered and EVA suits were doffed.

EVA # 8

Author: Health and Safety Officer Alex Coultrup

Purpose of EVA: Gathering soil samples and scouting for emergency shelters.

Start time: 1015 MDT

End time: 1335 MDT

Narrative: The EVA this morning started slightly after the beginning of the approved EVA window, as the crew was carefully gathering and sterilizing required scientific instruments according to XO Hume’s Planetary Protection Protocols. After we suited up and completed our 5-minute decompression in the airlock, we loaded our supplies into the Perseverance rover. Commander Dickstein and Crew Scientist Ettlin drove the Rover and HSO Coultrup took the ATV Serial Number 2. Starting charge on the Rover was 100% with 203.3 hours and the ATV required some choke before starting.

We traveled from the Hab to Entrance Road and proceeded south on Cow Dung Road for approximately 6 minutes until we reached Robert’s Rock Garden. Upon reaching the beginning of Robert’s Rock Garden, we parked our vehicles safely by selecting a spot on the side of the road where it was still fairly straight, before the sharp turns into the rock garden began. Using the analog map, we confirmed that our travel calculations had been accurate. From there, we embarked on foot to explore the rock garden and determine points of interest. As always, we carried the EVA med kit with us for this.

While at the rock garden, we conducted a thorough exploration and surveyed the area for locations that might make for suitable emergency shelters. We also collected multiple soil samples for our scientific research. When we had completed gathering the samples, we returned to our vehicles and proceeded north on Cow Dung Road to Entrance Road, and back to the Hab. Upon returning, the Rover displayed 203.5 hours and 100% charge.

EVA Report #4 – April 15th

Crew 245 EVA Report 15-04-2021

EVA #4

Author: Shayna Hume, Executive Officer

Purpose of EVA: Science & Operations EVA. Firstly, we wanted to take soil samples at a ridge geological location, and we wanted to identify an emergency shelter location at the same.

Start time: 09:30 nominal.

End time: 12:30 nominal, 11:30 actual after a return from inclement weather.

Narrative: We left for the EVA promptly, Hume and Hariharan on rover and Hernandez on ATV 1. After a brief time, Hume identified a honk behind us, and we were able to pull to the side of the road and notice a “breaking sim” Truck behind us, trying to pass us. They did so. We continued and quickly arrived at the stopping coordinates on the road. We found a smooth path down to what seemed a streambed adjacent to the ridge we were targeting. We immediately identified an emergency shelter location and took notes on it. After that, we found three soil locations on the ridge itself. Upon seeing darker clouds, we immediately began to head back. By the time we were at the vehicles, the wind was extremely high. When we got back into radio range, we found out that the Habcomm had already been asked to emergency return us to shelter. We were back and done with the 5-min airlock duration by approx 11:30.
