Crew 200 EVA Report 12-13-2018
EVA #6
Author: Lindsay Rutter
Purpose of EVA: 1) Map out locations that allow radio communication between EVA crew and HabCom around Phobos Peak 2) Test how EVAs can safely and effectively be conducted with three-member crew, including rover use.
Start time: 14:12
End time: 16:00
Narrative: With media guests visiting the habitat today, our EVA was pushed back in time, which was authorized by Shannon. We continued our communication and radio strength and connectivity testing protocol today. Our EVA began with an engineering check. We then used Opportunity to drive north on Cow Dung Road. We intended to stop at the west end of Stream Bed Connector, but we inadvertently stopped at the east end of Galileo Road 1104, which we walked along for almost its entirety. Through our GPS system and our communications with HabCom, we realized we were probably on Galileo Road 1104 and so we returned back to the west end of it. We then continued driving Opportunity northward. We intended to explore areas about 1 kilometer north of Reservoir Dam, but by the time we were 0.2 kilometers north of Reservoir Dam, we had lost connectivity with HabCom for several consecutive radio tests. This lack of connectivity continued even when we parked the rover and stood on higher points. We decided to return driving south, communicating with HabCom throughout the return, sometimes having to park the rover and stand on higher points. Arriving back at the habitat about fifteen minutes early, we explored the hills on the west side of the habitat, still following our communication and radio strength and connectivity testing protocol. We are excited to report that the battery usage on Opportunity was much more efficient than it has been lately.
Destination: Galileo Road 1104, above 0.2 kilometers north of Reservoir Dam

EVA #5
Author: Antoine Bocquier
Purpose of EVA: 1) Map out locations that allow radio communication between EVA crew and HabCom around Phobos Peak 2) Test how EVAs can safely and effectively be conducted with three-member crew, including rover use.
Start time: 10:35
End time: 12:30
Narrative: The media filming around the Hab this morning, we had to delay a bit our planned EVA. In addition, in agreement with Shannon they were using the rovers, so we had to change our plans and perform a walking EVA. We chose to go to Phobos Peak, which we could not reach on our EVA monday, to map the radio coverage. The walking went very fine (30mn to get to Phobos Peak), once there, we walked north up to Mountain Goat Trail before coming back to the Hab by the north. Radio link was pretty clear all along, we estimated that Phobos Peak could be a very good location to settle a radio relay (to explore eastern areas) and may be accessible on its northern side. We are currently processing the acquired data (radio check every 2mn + GPS positions) to complete our radio coverage map.
Destination: Phobos Peak + Southern part of Mountain Goat Trail
Coordinates (use UTM NAD27 CONUS): 519500 E – 4250500 N

EVA #4
Author: Antoine Bocquier
Purpose of EVA: 1) Map out locations that allow radio communication between EVA crew and HabCom, in northern and southern regions 2) Test how EVAs can safely and effectively be conducted with three-member crew, including rover use.
Start time: 9:10
End time: 10:55
Narrative: After the engineering tour, we drove with Curiosity to the north, then to the south to explore and map the regions of communication strength/readibility. We applied a communication protocol to control the radio strength/readability (QSA/QRK codes) every minute and communicate GPS coordinates every 5mn. We first drove to Galileo road, planning to stop for a short walk at Connector Stream Bed. However we did not find both of them, being focused on our communication test protocol and with the recent snow melting. We went further than expected to the north, up to cowboy’s corner where we stopped as we realized from the transmitted coordinates that we were too far. On our way back to the Hab to change the rover and go to the south, we confirmed the location of Connector Stream Bed. Arrived at the Hab at 9:50, we took Opportunity to go to Robert’s Rock Garden, applying the same communication protocol. From there we walked along Kissing Camel Ridge Edge to complete yesterday’s mapping of this area. We then drove back and came back on time at the Hab. Analysis of the acquired data is in process and the first results are promising!
Destination: Galileo Road (up to Cowboy Corner) + Robert’s Rock Garden

EVA #3
Author: Antoine Bocquier
Purpose of EVA: 1) Map out locations around the habitat that allow for radio communication between EVA crew and HabCom, 2) Test how EVAs can safely and effectively be conducted with three-member crews.
Start time: 10:35
End time: 12:30
Narrative: Crew conducted first 3-crew member EVA to explore and map the regions of communication strength/readibility. We applied a communication protocol to control the radio strength/readability (QSA/QRK codes) every minute and communicate GPS coordinates every 5mn. We planned contingency plans for loss of signal and navigation. Afterwards, the crew mapped the locations of perceived path by each crew member against the estimated path based on recorded GPS coordinates. We could not explore as much area as planned (we planned to have a walk to Phobos’s Peak) given the time left but the experiment was a success, both on the EVA crew and HabCom sides for a 3-member crew.
