Crew 219 EVA Report 11 JAN 2020

EVA#: 12

Author: Nathan Hadland

Purpose of EVA: The primary purpose of this EVA was sampling for our geology project. Post-EVA, we collected data for our biometrics project.

Start time: 1335 hrs

End time: 1553 hrs

Narrative: Due to the assistant director using the rovers, the EVA was delayed by 30 minutes to allow Spirit to achieve 100% SOC. At 1335 hours, EVA #12 initiated a 5-minute decompression and moved to Curiosity and Spirit. After reporting SOC and hours, we progressed north along Cow Dung Road until we reached Tank Wash. We moved east on

foot through Tank Wash until just above Murphy’s Canyon. After taking 5 regolith samples and 3 biological samples (lichen), the crew then then turned around and returned to the rovers. Curiosity and Spirit proceeded safely back to the Hab at 1548 hours and the EVA crew successfully pressurized in the air lock at 1553 hours.

Destination: Tank Wash

Coordinates: 0519400/4253800

Participants: Nathan Hadland (XO), Alejandro Perez (ENG), Robinson Raphael (ASTRO), Abdul Elnagdi (GEO)

Roads and routes per MDRS Map: North along Cow Dung Road until 518100/4253550 and then proceeding East on foot through Tank Wash until just above Murphy’s Canyon.

Author: Nathan Hadland

Purpose of EVA: The primary purpose of this EVA was sampling for our
geology project. Post-EVA, we collected data for our biometrics
project.

Start time: 1253 hrs

End time: 1513 hrs

Narrative: EVA #10 initiated a 5-minute decompression at 1253 hours
and headed north towards North Ridge. We then proceeded up Hab Ridge
using the Sagan Street (1103) access road. Abdul Elnagdi (GEO)
identified a site for sampling and we took 5 samples at the top of the
ridge and recorded GPS locations. The EVA team then walked along Sagan
Street until reaching Mid Ridge Planitia and took 5 additional
samples. The team then proceeded back along Sagan Street and descended
Hab Ridge. The team arrived safely back to the Hab and picked up the
optical mount for analysis. The EVA crew entered the air lock at 1508
hours and successfully pressurized in the air lock at 1513 hours.

Destination: Just east of Mid Ridge Planitia

Crew 219 EVA Report 08-01-2020 EVA #5 Author: Dave Masaitis Purpose of EVA: Geologic sample collection and monitoring of dust mitigation experiment Start time: 0904 hrs End time: 0931 hrs Narrative: EVA #5 departed the Hab on foot at 0904 hours and moved over to the dust mitigation experiment. R. Raphael made his observations, and the EVA team then moved west to ascend Hab Ridge. By the time the team crested the first set of hills on the way to the ridge, D. Masaitis called a short halt to allow team members some time to allow visor fogging to subside. Within minutes, D. Masaitis was able to make the observation that his helmet’s air vents were misaligned and were only able to defog the very bottom corners of his visor. Given that he was not fully fogged, the team decided to try and continue climbing. Three-quarters of the way up the ridge line, D. Masaitis noted that snow cover and ground conditions would prohibit the whole team from making it up the ridge line with the necessary sampling equipment. He conferred with H. Blackburn, and they decided to abandon the climb in the interests of crew safety. D. Masaitis called N. Hadland at the hab to discuss options. Since a last minute change of sampling location would violate procedure, D. Masaitis made the call to terminate the EVA, and EVA #5 returned to the airlock at 0931 hours. Destination: SW of Hab Ridge Coordinates: 0517500/4250100 Participants: D. Masaitis (CO), A. Perez (ENG), H. Blackburn (LSO), R. Raphael (ASTRO) Roads and routes per MDRS Map: W to Hab Ridge, S on Hab Ridge Rd. to target location

EVA #6

Author: Nathan Hadland

Purpose of EVA: Sample collection for mineralogy project and taking photographs of the optical mount for dust mitigation project

Start time: 1252 hrs

End time: 1449 hrs

Narrative: Under HSO advisement, a personnel change was made in the EVA crew. EVA #6 initiated a 5-minute decompression at 1252 hours and moved out on foot to the vicinity of the Robotic Observatory. After taking photographs of the optical mount setup to check for dust collection, we moved back to Curiosity and Spirit. After reporting SOC and hours, we progressed south along Cow Dung Road. We dismounted the rovers just past Robert’s Rock Garden and moved east on foot along the base of Kissing Camel Ridge E and then north towards Phobos Peak. After reaching an area directly south of the peak, Abdul (GEO) identified a flat site for sample collection. We collected 5 samples in a grid and recorded GPS locations. The EVA crew then headed southwest back to the rovers. Curiosity and Spirit proceeded safely back to the Hab at 1444 hours and the EVA crew successfully pressurized in the air lock at 1449 hours.

Destination: Phobos Peak

Coordinates: 0519500/4250100

Participants: Nathan Hadland (XO), Abdul Elnagdi (GEO), Keith Crisman (HSO), Robinson Raphael (ASTRO)

Roads and routes per MDRS Map: South along Cow Dung Road (0110), parked just south of Robert’s Rock Garden and then proceeded east on foot towards Kissing Camel Ridge E and then north towards Phobos Peak.

EVA #3

Author: Dave Masaitis

Purpose of EVA: Geologic sample collection

Start time: 0903 hrs

End time: 1002 hrs

Narrative: EVA #3 entered the airlock at 0858 hours, and departed the Hab on foot at 0903. The EVA team moved north around the science dome and headed out towards North Ridge. Due to ambient temperature hovering around freezing, only a third of the distance towards North Ridge had been covered before the majority of crew members were reporting excessive visor fogging. CO called a short halt fogging and then resumed movement towards North Ridge. A second short halt had to be conducted just shy of the target sampling area for the same reason. Once on the target area at the base of North Ridge, crew members identified 5 locations to sample from in accordance with the crew geologist’s sample plan. The coring tool provided did a sufficient job of collecting the first sample, but the substrate was so frozen that the EVA team was unable to get the sample back out of the coring tool. CO crested a nearby ridge to reestablish communications with the Hab, and a secondary sampling technique was approved by the crew geologist. The EVA team collected and recorded locations of 10 samples, and then the CO and HSO discussed the plausibility of summiting North Ridge. Both concurred that between ground conditions and the persistent visor fogging being experienced by most of the team would make a summit attempt unsafe, so the EVA team opted to return to the Hab. EVA #3 reached the airlock at 1002 hours, for a total EVA duration of 59 minutes.

Destination: Vicinity of North Ridge

Coordinates: 0518600/4250800

EVA #4

Author: Nathan Hadland

Purpose of EVA: Sample collection for mineralogy project and deployment of optical mount for dust mitigation project

Start time: 1250 hrs

End time: 1434 hrs

Narrative: EVA #4 initiated a 5-minute decompression at 1250 hours and moved out on foot to the vicinity of the Robotic Observatory. After setting up our experimental optical mount and safety flag to mark its location, we moved back to Curiosity and Spirit. After reporting SOC and hours, we progressed south along Cow Dung Road. We dismounted the rovers just past Robert’s Rock Garden and moved east on foot along the base of Kissing Camel Ridge E. The Crew Geologist identified a site with no snow cover and flat terrain for sample collection. We collected 5 samples in a grid and recorded GPS locations. After sample collection, we found a safe route up the side of Kissing Camel Ridge without snow cover and took 3 additional samples on the side of the formation. We then headed down and returned to the rovers. Curiosity and Spirit proceeded safely back to the Hab at 1428 hours and the EVA crew successfully pressurized in the air lock at 1434 hours.

EVA #: 8

Author: Cesare Guariniello

Purpose of EVA: Seismometric measurements; EVA and EMU evaluation project; reliability project

Start time: 10:57

End time: 12:59

Narrative: Pat and Cesare drove East on Galileo / Cactus road on a cold, battery-draining day. Once they found a suitable spot in the lowlands they set up the seismometric experiment. Then, they performed a reliability and repair study, evaluating the execution of operations via radio communication. Pat served as the expert, guiding Cesare via radio. The experiment simulated a rover battery failure to be repaired in 10 steps, which included cleaning the area around the seats from ice, putting the map in the glovebox, and reciting poetry. After this, Pat and Cesare performed seismometric readings before heading back to the hab

Author: Cesare Guariniello

Purpose of EVA: Weather observation; EVA and EMU evaluation project; reliability project

Start time: 14:18

End time: 14:54

Narrative: After heading out, the crew found out that the rovers were not fully charged. The commander called for cancellation of the driving, and allowed the crewmembers to perform weather observation and reliability project in the vicinity of the habitat. The crew reached the MDRS sign and simulated a situation of radio failure, with consequent EVA abortion and implementation of protocols for
communication and safety, which included having the crewmember experiencing a radio failure to walk between the two crewmembers with working apparatus.

EVA #: 6

Author: Cesare Guariniello

Purpose of EVA: weather observation project; EVA and EMU evaluation project

Start time: 9:57
End time: 12:01

Narrative: Cesare, Ben, and Shefali drove to the north side of Kissing Camel range, where Ben took radio measurements and Cesare proposed potential scenarios for crew decision-making.

After collecting a few rock samples, the crew drove the rovers to the south of the range, which is exposed and clear of snow.

More radio measurements were taken, and the crew could climb the south side of the West Kissing Camel range. On the way back, Ben took more radio measurements along the first ridge south of the habitat.

EVA #: 7

Author: Pat Pesa

Purpose of EVA: crew decision-making evaluation and radio measurements (during transfers); seismic measurements to evaluate subsurface layers (once at destination); EVA and EMU evaluation (once back in habitat)

Start time: 12:49

End time: 14:57

Narrative: Luz Ma and Pat took the Curiosity and Spirit rovers to just south of Kissing Camel range to the Hippo formation. Pat set up his Seismic equipment with the help of Luz Ma (lots of untangling wires) and started recording data.
It is a quite fun experiment because, after the tedious setup, you get to "smack" the ground with a sledgehammer to generate waves for the geophones to pick up! After these tests, Luz Ma continued her Climate and Weather readings, and we embarked on a short journey near the area.

Besides the overabundance of slushy snow and mud, the EVA was greatly successful and led to some great science and exploration.

EVA #: 5

Author: Cesare Guariniello

Purpose of EVA: crew decision-making evaluation and radio measurements (during transfers); seismometric measurements to evaluate subsurface layers (once at destination); EVA and EMU evaluation (once back in habitat)

Start time: 13:15

End time: 15:59

Narrative: After loading on the rovers the necessary equipment for the research projects, we began driving along Cow Dung Road. The road is well marked, with streams of icy water melting down. Snow is completely melted in certain point and about one inch deep on others. The ride had been very smooth and safe, and the rovers made it to the intended destinations with good residual charge. Ben took radio measurement along the road, as a passenger on Curiosity rover. Once at destination, we began to slowly prepare Pat’s experiment. This required us to extend a measuring tape for about 30 meters and, after having removed some snow, place 24 sensors one meter apart from each other. The seismometric sensors, connected to a laptop, record the propagation of seismic waves generated by a hammer hitting a metal plate that we laid on the ground at various locations along the sensor network. The preparation took about 25 minutes and gave us a good idea of the challenges faced by astronauts working in EVA. After the experiment, we walked the first few feet of Brahe Hwy before heading back. On our way back, Ben took more radio measurements south of the intersection with Galileo Rd and close to the habitat.
