EVA # 11

Author: Shayna Hume, Executive Officer

Purpose of EVA: Gathering soil samples on a ridge area.

Start time: 1000 MDT

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

Narrative: The EVA this morning started on schedule after the crew had carefully gathering and sterilizing required scientific instruments in order to meet the crew’s determined Planetary Protection Protocols. After suiting up, the crew waited 5 minutes before exiting. Today, the crew departed from the Hab and Hab Grounds by foot, heading northwest.

After a thirty-minute hike, we reached the top of the western ridge and began heading North towards Schubert’s Pass. After taking soil samples along the ridge, the team took a few minutes to admire the incredible view of North Ridge, Schubert’s Pass, and the western buttes.

After determining there were no valid candidates for emergency shelter, 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: Executive Officer, Botanist, Engineer

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

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.

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.

Destination: Cowboy Corner Local Area

EVA # 3

Author: Dylan Dickstein

Purpose of EVA: Discover emergency shelter locations and perform soil sampling.

Start time: 900 MDT

End time: 1200 MDT

Narrative: After spending five minutes in the airlock, the Crew Scientist and Commander got in the Rover Perseverance and the HSO mounted ATV 1. The EVA crew started heading north on Cow Dung Road and found that about 0.5 km north of Pooh’s Corner, communication between the Hab and the EVA crew became noisy with static. Less than 0.5 km further, all communication was lost. The EVA crew decided to turn around and return to reobtain communication. The EVA crew notified the Hab of the loss of communication further north and inquired about a change in destination. The Hab asked OUTPOST for recommendations on whether to proceed or change destination. OUTPOST informed the Hab that loss of communication is acceptable, so long as the EVA team can communicate among each other. The Hab and EVA crew discussed contingency scenarios if the EVA crew did not return by the end of the EVA window. It was settled that phone communication would be used past the window as a safety mechanism to ensure the EVA team is alright. This would be a purposeful break in simulation to maintain the safety of the participants. The EVA crew then continued north and parked the rover and ATV at the edge of the Special Region. The GPS coordinates were marked on the device and were checked against the target. It was found that the EVA crew was southeast of the destination by approximately 0.4 km. The EVA crew set out on foot and identified a potential emergency shelter location on the way. The location was marked on the GPS and the quality of the shelter was determined. The team found a location within 0.1 km of the target and retrieved two sets of soil samples there. An additional potential shelter was found, but time only allowed for a coordinate on the GPS device to be obtained. The EVA crew gave a 1.5x contingency on the return time (e.g. 25 minutes expected, so 38 minutes were allotted for return time). The EVA crew began the return at the start of the 38 minute window. A few stops were made to mark various points on the GPS and check that the EVA crew was holding up well. The Crew Scientist attempted to reestablish communication with the Hab within 2 km of the location where communication was lost previously. Attempts were made every 30 seconds thereafter. About 0.5 km north of the location where communication was previously lost, the Hab returned our call with static. A coordinate was marked in the GPS device. The EVA team informed the Hab about the highlights from the mission and called when the Hab was in sight. Permission was received for entering the “Hab Zone” (Entrance Road), the rover and ATV were parked, rover power cord reattached, tachometer and battery level noted, and permission to enter the airlock received. The Hab let the EVA team know when five minutes elapsed and suits were doffed.

EVA #2

Author: Shravan Hariharan, Crew Engineer

Purpose of EVA: Practice EVA to Pooh’s Corner, Round 2

Start time: 1100

End time: 1200

Narrative: Immediately after the first EVA Crew returned to the Habitat, it was time for the remaining three crew members to embark on their practice EVA! After discussing lessons learned with the initial EVA crew, the Commander, Crew Engineer, and Crew Botanist all suited up and embarked on EVA. The main goal of this Practice EVA was to formalize EVA protocols, including a medical check by the HSO prior to departure, and an order in which Crew Members should get ready for EVA. Upon arrival at Pooh’s Corner, the Crew practiced their Emergency Shelter Identification procedure – the first shelter was named the Dusty Ditch! After identification of the first shelter, both the Commander and Crew Engineer’s communications systems failed – the batteries of the radios were too low. At that point, it was determined that continuing on EVA was too dangerous, so the Crew Botanist communicated with the Hab, and led the crew back to the Habitat using hand signals. The Crew Commander is currently working on standardizing hand signals in case we have future communications failures. We have learned how to test the batteries prior to departing on EVA, so we are thankful that we were able to experience this failure and learn from it!

EVA #1

Author: Shravan Hariharan, Crew Engineer

Purpose of EVA: Practice EVA to Pooh’s Corner,

Start time: 0900

End time: 1030

Narrative: The three crew members were all extremely excited to participate in their first EVA, and take our first steps on Mars! First words were “We go to Mars together!” from our Executive Officer. The ATV started with a minor amount of choke and the rover worked flawlessly; the ride to Pooh’s Corner was relatively quick. XO observed that riding in the ATV with the two-piece suit could be uncomfortable. The MDRS map was accidentally left in the Habitat, so the remaining Crew Members in the Hab provided verbal navigation. Crew Scientist brought the crew to a location for soil sampling, and the three EVA members took photos and videos of each other to document the occasion. Three samples were collected while practicing the techniques and training one another, although the soil was rockier than expected. After taking some additional photos, the EVA crew drove back to the Habitat. Brief issues such as the Rover being left in “Forward” were quickly resolved, and the Crew returned to the Habitat. We are grateful to the Director for suggesting this practice EVA, as we were able to successfully practice our EVA protocols and operations, such as donning and doffing the suits, collecting supplies, and communicating as a team.
