Crew 236 EVA Report 30-DEC-2021

EVA # 11

Author: Vladimir Zeltsman

Purpose of EVA: Evaluation of soil and ground conditions for additional potential habitat locations and a geology survey of the Summerville formation/layers

Start time: 9:00 am

End time: 13:30 pm

Narrative: The EVA was originally requested for near and east of the summer view overlook, but changed to Candor Chasma. The coordinates are originally N4253000 W522800 but rescheduled for N4251000 W521000. The crew entered the airlock at 9:15 and headed towards Candor Chasma shortly after. Once both rovers were parked on Galileo, the crew headed east toward the destination. After hiking down into Candor Chasma, 1 location was measured to see if it was large enough for a habitat. The one location was open and had acceptable ground and soil conditions but significant terraforming would be required to make a road and clear the land of all fauna. This leads Vladimir (GHO) to believe that further east into Candor Chasma, there could be locations large and solid enough for a potential habitat location. At 11:15, the crew turned around and headed back to the rovers due to two suit failures. The crew arrived back at the Hab at 12:26. The EVA, although not producing the desired results, is still considered a success, since multiple sites were evaluated.

EVA # 9

Author: Kasey Hilton

Purpose of EVA: Evaluation of soil and ground conditions for additional potential habitat locations

Start time: 10:30

End time: 14:00

Narrative: The crew entered the airlock at 10:35 and headed towards Candor Chasma shortly after. Once both rovers were parked on Galileo, the crew headed east toward the destination. After hiking down into Candor Chasma, 2 locations were measured to see if they were large enough for a habitat, but neither were, however the ground and soil conditions were acceptable. This leads Vladimir (GHO) to believe that further east into Candor Chasma, there could be locations large and solid enough for a potential habitat location. At 12:15, the crew turned around and headed back to the rovers. The crew arrived back at the Hab at 12:54. The EVA, although not producing the desired results, is still considered a success, since multiple sites were evaluated.

EVA # 8

Author: Kasey Hilton

Purpose of EVA: Collection of samples from region D and Mancos Shales from Copernicus Hwy for analysis of water content and analog for rocks found in Gale Crater

Start time: 9:00

End time: 13:00

Narrative: EVA prep started around 8:30 and the group going on EVA was in the airlock at 9:02. Shortly after, the two pairs climbed in Spirit and Curiosity and headed towards region D using Cow Dung Rd and Brahe Hwy. About 30 minutes later, the group reached the moon overlook (region D) and parked the rovers to start walking down Copernicus Hwy in search of gypsum and Mancos shale. At the intersection of Brahe Hwy and Copernicus Hwy, the group found multiple samples of gypsum. Further down Copernicus Hwy and closer to the boundary walls, the group found samples of Mancos shales. Cesare (XO) was particularly excited about the mancos shale because he had been trying to find some for the last four years without any luck. The group turned around and walked back along Copernicus Hwy until they reached the rovers. They arrived back at the Hab at 11:46, happy that the research objectives they set out to accomplish had been achieved.

EVA #4

Author: Cesare Guariniello

Start time: 9.31 AM

End time: 12.02 PM

Narrative: The team began EVA preparation around 9 and entered the airlock at 9.31, just at the beginning of the EVA window. Crew Journalist replaced his earpiece that caused issues on EVA #3. After depressurization, the crew boarded the vehicles and headed south along Cow Dung road. After a drive of about 5 km, the crew walked towards Barainca Butte. Along the way, XO had a couple of stops to collect rock samples. One rock is brown and black and heavily vesiculated (possibly scoria). Other rocks came down from upper layers of hard mudstone and conglomerates. Meanwhile, SCI took rock temperature measurements for a project on thermal inertia of minerals at MDRS. ENG and JOU assisted and documented the work. The EVA crew reached the south side of Barainca Butte and continued its research proceeding counterclockwise around the butte. After having walked about one quarter of the perimeter of the butte, JOU noted some increasing fogging of the helmet and asked to position the fan switch at maximum speed. The fogging decreased, but JOU reported the fans slowing down. The crew decided to reduce the EVA time and began walking towards the vehicles. Unfortunately, within just a few minutes, JOU experienced a total loss of the fans which, on Mars, would require an urgent contingency rescue or would result in loss of the crewmember. Since the fogging disappeared quickly and JOU reported receiving enough air from underneath the collar, he elected to keep his helmet on for the drive back to the Hab. During the drive back, the crew met some astronauts onboard terrestrial-looking vehicles. The crew stopped the vehicles on the side of Cow Dung road, south of Kissing Camel range, to let the unknown astronauts pass by, with a brief and very amicable exchange of nods and smiles. The crew returned to the Hab about one hour earlier than the expected time, without further incidents.

Destination: Around Barainca Butte

EVA #3

Author: Cesare Guariniello, XO/HSO Crew 236

Start time: 9.41 AM
End time: 10.28 PM

Narrative: The team first entered the airlock at 9.41. During depressurization, one crew member experienced a problem with the microphone, and after 3 minutes of repressurization the crew came back into the Hab to fix the problem. After the second depressurization, the EVA crew boarded the vehicles and headed south.

About 10 minutes into the drive, loud static was heard in the communication channel. The EVA crew stopped at the side of the road to troubleshoot the problem. XO assessed the radios and found that one radio was stuck in transmission mode (TX), thus preventing one EVA crew member from receiving communication. Switching a radio showed that the issue was in the earpiece, possibly the cable (since the earpiece does not have a vox setting).

As per EVA rules, for reasons of safety, the EVA was aborted due to one crew member has lost communication. The EVA crew returned to the Hab immediately, with no further anomalies.

Destination: Around Baranca Butte (INTENDED)

Crew 260 EVA Report 02-11-2021

EVA # 1

Author: Commander Jen Carver-Hunter

Purpose of EVA: Geologic sample collection

Start time: 10:30

End time: 12:30

Narrative: The EVA team departed the Hab 10:40, taking Cow Dung Road in medium-range speed, to see how Oppy would perform after the overheating during the training day. After crossing Robert’s Rock Garden, we incremented the speed and reach the 1101 intersection (Note for future EVAs and crews to take the southern entrance to not disrupt the natural wash). We reached our desired location where we collected our first geological targets as part of our mission objectives. After finding the needed samples, we went back to the main road and on our way North we stopped just before the Kissing Camels to go West and collect our petrified wood samples. We explored all the way to the beginning of the wash and noticing what time was it, we proceeded to return to the Hab after a successful EVA.

Destination: Road to Barranca Butte and Southwest Kissing Camel Ridge

Coordinates (use UTM NAD27 CONUS): 519700, 4247300 and 518200, 4249300

Participants: Atila, Katie, Adela

Road(s) and routes per MDRS Map: Hab road to Cow Dung Road to 1101 and back

Mode of travel: Rovers on roads, on foot off road

EVA # 2

Author: Commander Jen Carver-Hunter

Purpose of EVA: Geologic sample collection

Start time: 2:00

End time: 3:30

Narrative: The EVA team departed the Hab at 14:00. We followed Cow Dung Road to the 1101 intersection, and followed 1101 a few hundred yards to our first destination. We collected samples as part of our science mission objectives. Then we returned to the main road and turned to the north. The Opportunity Rover overheated just south of Kissing Camel Ridge, and we safely moved her to the side of the road. We piled into the remaining 2 rovers and continued on to Kissing Camel Ridge, where we collected samples at the base of the wash. Due to the onset of headaches and thirst, the EVA team returned to the Hab earlier than expected at 1530.

Destination: Road to Barranca Butte and Southwest Kissing Camel Ridge

Crew 228 EVA Report 06-Oct-2021

EVA #6

Author: Inga Popovaite and David Laude

Purpose of EVA: Exploration of Candor Chasma

Start time: 13.00

End time: 16.00

Narrative:

Dave and Inga drove to one of the entrances to Candor Chasma and explored the beginning of the canyon. The area is beautiful and breathtaking; the canyon is worth spending more time in. There was ample evidence for water flow along dry stream beds with rounded pebbles along the bed. Sedimentary layers were abundant. Also seen is what appeared to be limestone. They took a lot of photos and a few videos for outreach purposes. Inga interviewed Dave about his love for canyons. They took four radios; two of them either died due to low battery or started malfunctioning. Wind picked up on the second half of the EVA during the drive back and it was hard to communicate with VOX setting on. The wind noise caused radios to activate transmit via the VOX function. This helped to drain the batteries. A couple of lessons for the future: backup radios are a must; when it is windy it might be better to have the radio transmit manually operated.

Destination: Candor Chasma.
