Crew 297 EVA Report 21-04-2024

EVA #9

Author: Matthew Lynch (Engineer)

Purpose of EVA: Perform the third ‘hiding’ EVA for the nuclear power project. Two members of Team A will go into the field and place the NPS for Team B to find on a future EVA. Potential NPS burial sites and geological sites of interest will also be observed.

Start time: 9:57 am

End time: 12:39 pm

Narrative: Starting on time and exiting the airlock, we placed the NPS in the back of Opportunity and headed North. As expected, the battery was at 55% when we were halfway down Brahe Highway. We parked the rover and saw what appeared to be a road heading North, we mistook this for route 1575 and attempted to follow this to reach the sea of shells, eventually realizing our error we circled back and followed the real road until we reached the moon overlook and eventually the sea of shells at 11:45 AM. We analyzed the area for potential digging sites and the ground looked excellent. However there were minimal ideal spots for placing the NPS. We began the walk back to the rovers and determined our best course of action was to not place the NPS, as the day was getting very hot, our EVA suit batteries were draining, and critically there were minimal good spots in the terrain to place the NPS. We returned back to the Hab at 12:40 PM. It should be noted there are some discrepancies between the MDRS map, the routes on the ground, and the Bureau of Land Management road markers, this was the primary cause for the challenges in reaching the Sea of Shells.

Crew 297 EVA 11 Report 21-4-2024    

EVA # 11

Author: Sarah Lamm

Purpose of EVA: To observe the grey geological unit seen from orbit.

Start Time: 7:37 AM

End Time: 10:11 AM

Narrative: We arrived at the grey unit and took gamma-ray measurements of it, specifically to see if the uranium content would be higher than the previous units. From there we traveled to the overlook, and just south of the Sea of Shells. Once we came back to the intersection of Brahe Hey and Cow Dung Row, we hid the NPS device for Matt’s L project.

Destination: Area between Sea of Shells and Overlook

Crew 297 EVA 4 Report 17-4-2024

EVA #4

Author: Sarah Lamm

Purpose of EVA: To locate the NPS from yesterday and to observe a geological formation that from orbit is redder than the surrounding location

Start Time: 9:36 AM

End Time: 1:00 PM

Narrative: We arrived at the first stop to locate the NPS device for Matt L’s research project. It was found quickly. From there we moved to the south and stopped at the location yesterday to test how easy it would be to dig in the regolith and to get initial Gamma-Ray Spectrometer readings of the regolith. We continued south to the region that looked redder from orbit, to take more observations of the regolith and the rocks. Lastly, we headed north toward the Hab and stopped at Robert’s Rock Garden to observe those rocks in comparison to those we had already seen.

Destination: Find the NPS, location to dig and gamma ray on regolith, redder area regolith & rocks, Robert’s Rock Garden (Stop #4)

Coordinates: 12S 518166N, 425092E (Stop #1); 12S 518065 4250003 (Stop #2); 12S 518819 4248714 (Stop #3); 12S 518278 4249467 (Stop #4)

Crew 297 EVA Report 18-04-2024

EVA #5

Author: Pawel Sawicki (Commander)

Purpose of EVA: This EVA will kick off the human-interaction study from CU Boulder (COHRINT Lab), where two crewmates will use the User Interface (UI) to monitor and interact with the robot as it traverses and records imagery of the relatively flat terrain. Thus it will also be the first time Case (the name of the robot) touches Martian regolith. The other half of the EVA crew will be in the vicinity (visual and audio site maintained) testing digging techniques that may be used to bury the [inert] NPS. Any dug-up holes will be filled in before the end of the EVA.

Start time: 9:50am

End time: 11:53am

Narrative: Today’s EVA was a first for the crew for many reasons. It was the first time we had four crewmates involved in the same EVA, the first time that Case got to test itself out on Martian regolith, and the first true attempt at digging the NPS. With four EVA members, Case (along with Case’s GSE), and a medley of digging tools, the exit via airlock took longer than nominal. Entrance into the Martian atmosphere required 5 minutes of depressurization so that two crewmates could leave along with the tools and the rover, 5 minutes of pressurization again, and finally 5 minutes of depressurization so that the remaining crewmates could exit. We finally arrived to our destination near Cow Dung Road approximately 26 minutes after first entering the airlock, determined to meet all our EVA objectives. Case was able to capture useful imagery of the surroundings, yet, it was not able to take off its metaphorical leash, needing to be monitored constantly and manually driven for a large portion of its adventure. The other two EVA crew mates had great success – digging a hole suitable for the NPS at a rate of 30 cubic feet per hour. Two hours had passed before the rover and related GSE were collected, the hole was filled up, and we started heading back home.

Crew 297 EVA 7 Report 19-4-2024
      
EVA # 7

Author: Sarah Lamm

Purpose of EVA: Team B for the NPS Project will travel to 300 m northwest of Cowboy Corner (based on the NPS location that Team A had chosen), and search a 250 m radius for the NPS. Once found, we will continued to explore the region for geological exploration.

Start Time: 1:00 PM

End Time: 2:28 PM

Narrative: Crew arrived at the destination about 30 minutes after leaving the Hab. Starting from the north we started looking for the NPS device. After about 20 minutes we located it in a gorge. From there we traveled south stopping to look at dark rock formations. At this point, it was discovered that Suit #11’s batteries were quickly losing charge, and the fan was not blowing as much air. We aborted the remainder of the EVA and headed for the Hab.

Destination: 300 meters NW of Cowboy Corner

Crew 297 EVA Report 19-04-2024

EVA #6

Author: Matthew Lynch (Engineer)

Purpose of EVA: Perform the second searching EVA for the nuclear power project. Mission support will have provided a simulated landing site for the NPS. The Crew Commander (not on requested EVA) will give an approximate landing site, which will be within 1000 feet from the real location. This EVA will utilize known searching methods to find the NPS. Once found, it will be collected and a new simulated landing site will be selected and recorded for the next EVA crew to recover.

Start time: 9:04 am

End time: 11:22 pm

Narrative: Having a slightly late start we suited up, left the airlock, and entered the rovers without any issue. At 9:31 Curiosity’s charge was at 56% and we were still approximately ~1km from the edge of our search area by road. After parking the rovers, we proceeded on foot until we reached the edge of our search area at 9:47. Once there we spread out and moved towards the center of the region. At 9:55 Matt S. noticed a small hill he could see the local area from and once he climbed it he spotted the NPS near the edge of our search area. We collected the NPS and returned the rovers to return to the hab. On our return we stopped and deposited the NPS for the following EVA (that day) to search for in an area. We then returned to the hab and entered the airlock at 11:17 AM.

Crew 297 EVA 8 Report 20-4-2024
      
EVA # 8

Author: Matthew Storch

Purpose of EVA: We first did another seek for the NPS Project, by traveling to the coordinates specified by Mission Support, and searching a 300 m radius for the NPS. We then evaluated the robot, excavated a site for placement of the NPS, and explored the surrounding region for geological purposes.

Start Time: 9:08 AM

End Time: 12:55 PM

Narrative: Crew obtained the NPS search coordinates and proceeded to the search area, which was near the Candor Chasma. We stopped just off Cow Dung road and proceeded on foot along the Gateway to Candor, to conduct the search. The crew split into 2 teams that straddled a ravine. Matt Lynch quickly spotted the NPS and we retrieved it and returned to the rovers. We then proceeded north along Cow Dung Road to Galileo Road and headed east on Galileo until we reached the turnaround limit on battery power. The turnaround point was not deemed suitable for the other mission objectives, so we started to return along Galileo road, stopping twice to evaluate possible sites to cover the remaining mission objectives. Once a suitable location was found, Pawel and Matt S set up the robot, while Matt L scouted for suitable nearby excavation sites and Sarah conducted geological studies of the area. The robot had problems connecting to its network and there was not much we could do in the field to address the problem, so we had to abandon that objective for today. All four EVA crew members then joined the excavation effort, using a variety of tools and working in shifts. In the end we were able to excavate deep enough to properly bury the NPS, but finished just in time to return from the EVA with a suitable time margin. Excavation was much more difficult than in the first location, with the regolith removal rate being about one half of what it was in the first excavation, despite having 4 crew members to work this excavation vs. 2 for the previous one.

EVA # 1

Author: Sarah Lamm (Geologist)

Purpose of EVA: EVA certification training to Marble Ritual as requested by the MDRS.

Start time: 2:00 pm

End time: 3:00 pm

Narrative: We arrived at Marble Ritual with Spirit and Opportunity, and proceeded due east for about 270 m to the ritual buckets. After each person dropped a rock in the bucket, we proceed to examine the most Northwestern mound (about 4250921 N 518693E) within 30 meters of the Marble Ritual Posts. There we saw evaporated stream beds, filled with fine grained red sediments, as well as irregular white and red fine-grained patches. From there we proceed to the center mound, which is southeast of the first mound. and climbed to the top (about 4250899 N 518703 E). We quickly decided to leave as the wind was much stronger at the top. We briefly explored the shorter Northeastern mound (about 4250925 N 518714 E), until we descended at 2:20 pm due to the wind picking up. On the ground, we observed ventifact sandstones, as well as desert vanish. At 2:34 pm the crew returned to the rovers and parked at the Hab at 2:39 pm.

A singular curious alien coming from the south was spotted on Cow Dung Road at 2:21 pm. They seem to observe the EVA team and the Mars Desert Research Campus for about 10 minutes, until they left going north on Cow Dung Road.

EVA #2

Author: Matthew Lynch (Engineer)

Purpose of EVA: This was the initial training EVA for the second half of our crew. The goal was to go to Marble Ritual, briefly explore the immediate area, and return to the hab.

Start time: 4:00pm

End time: 4:55pm

Narrative: After suiting up for the first time we made our way to the airlock. We unplugged Curiosity (Matt L. + Dave) and Opportunity (Matt S.) was already unplugged. We made our way to Marble Ritual and each added a martian stone to the containers. Enjoying our first EVA, we performed some brief exploration of the area in the immediate vicinity. We saw several alien tourists observing the hab, some interesting rocks that we collected for geological inspection, and some extremely large semi-humanoid footprints that we photographed for analysis. Return to the rovers and the hab was done with no issues.

Crew 297 EVA Report 16-04-2024

EVA #3

Author: Matthew Lynch (Engineer)

Purpose of EVA: Perform the first EVA for the nuclear power deployment project. Mission support provided a simulated landing site for the NPS. The Crew Commander gave an approximate landing site, which was to be within 300 m from the real location. This EVA utilized known searching methods to find the NPS. Once found, NPS is collected and a new simulated landing site will be selected and recorded for the next EVA crew to recover. A potential secondary objective of testing excavation for the NPS was also added.

Start time: 1:40pm

End time: 5:09pm

Narrative: The initial GPS coordinates given to us provided a 300m radius search area, centered on the hab. Suiting up and leaving the habitat went as expected. After depositing our heavier equipment (shovel & pickaxe) into the rovers we made our way to north of the Hab and began on the footpath there to seek higher ground. We climbed the significant hills in this area and saw no signs of the NPS, then proceeded to fan out and move south/south-east around our search area. After ~40 minutes on foot, We saw a highly reflective object in the far distance and elected to return to our rovers and drive towards it. We reached the boundary of the search area and the object was still significantly far so it was assumed to not be the target. From here we began another search on foot of the North to South-east region of our expected landing zone. After ~90 minutes of searching HABCOM updated our search region to 100m. After a further 60 minutes of unsuccessful searching it was discovered that a technical error had led to the wrong GPS coordinates being used. Once corrected, HABCOM provided us with the actual NPS landing spot, approximately 1km to the south of the hab. We made our way there with the rovers and found the NPS in its expected location. On the way back to the hab we successfully placed the NPS in a new landing spot at [REDACTED] for tomorrow’s EVA to search for. Many aliens were observed today.
