Crew 200 EVA Report 11-12-2018

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!

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.

Destination: Kissing Camel East Ridge

Coordinates (use UTM NAD27 CONUS): 519000 E – 4249500 N to 518500 E – 42505000 N

EVA #2

Author: Makiah Eustice

traveled until we could spot purple-like regolith. We hiked about 12
meters to collect a sample and view the landscape. We walked back.

EVA Report For 25 October 2018 – EVA3
Author James Burk
Purpose of EVA:
1. Scout Candor Chasma for VR footage
2. Capture 360 and gimbaled camera footage of the MDRS and typical EVA activities.
3. Test out new suits and get feedback.
4. Test out GPS unit.
Destination: Candor Chasma
UTM NAT27 Coordinates: 4250500, 521500
Participants: Max Boyce (Lead), James Burk, Jim Ehrhart, Robert M. Narrative:
We travelled up the road to look for the crossroads to get to Candor but we were not able to find it the first time (or the second time). Eventually we crossed over to the eastbound road and approached the canyon. Around this time we lost connection with Habcom, and stopped our rovers. 2 of us climbed up a ridge (might have been Phobos Peak) to reestablish contact and scout the area. Once we were done, we realized that one of the two rovers was below 60%, and thus we had to immediately return to base.
From the engineering report: Opportunity experienced non-nominal behavior during EVA 3. Rover was carrying larger team members, Robert (5’7”) and James (6’9”) and their knees apparently hit the gear buttons randomly that resulted in the rover being in High gear for portions of the trip and rapid battery consumption. Approximately 100m from the Hab the rover was at 25% and the “motor overheat” lamp came on and the rover stopped. The crew pushed it back to its proper parking spot and used a spare extension cord from the GreenHab to plug it in.

EVA Report For 25 October 2018 – EVA4
Author James Burk
Purpose of EVA:
1. Scout Lith Canyon area for VR footage.
2. Capture 360 and gimbaled camera footage of the MDRS and typical EVA activities.
3. Test out new suits and get feedback.
4. Test out GPS units. Gather GPS waypoint data.
Destination: Lith Canyon
UTM NAT27 Coordinates: 4256046 519257
Participants: Max Boyce (Lead), Shannon Norrell, Marge Lipton, Robert M. Narrative:
All objectives achieved. The team drove the two rovers (Spirit and Curiosity) up to Lith Canyon. As soon as they reached the crossroads north of Pooh’s Corner, they lost Habcom communication as per EVA3. They were able to reach Lith Canyon and survey the area for VR. Also, they took several GPS coordinate readings of various landmarks which we thought future crews might find helpful. We have also converted these Lat/Long readings into NAT27 CONUS.

EVA Report For 22 October 2018 – EVA1

Author James Burk

Purpose of EVA:

1. Capture 360 and gimbaled camera footage of the MDRS and typical EVA

activities.

2. Test out new suits and get feedback.

3. EVA and Rover training of crew.

4. Daily engineering readings.

Destination: Pooh’s Corner

UDM27 Coordinates: 38.41 N, 110.78 W

Participants: Max Boyce (Lead), James Burk, Jim Ehrhart, Shannon Norrell.

Narrative:

All objectives achieved. Our 360 and gimballed footage is amazing.

Pooh’s Corner was the original destination, which was quickly achieved

in the first 15 mins of the EVA. We requested permission from Hab

Comm to requisition 2 rovers for a short drive south to Barainca

Butte. On the way, we were intercepted by the director who declined

permission for us to continue the EVA to Barainca Butte. We turned

around and returned to the Hab safely. We used rovers Opportunity and

Curiosity.

Crew 195 EVA Report 25May2018

EVA Report

EVA 5

The crew set out to the nearby site they’ve dubbed the “martian graveyard” to search for signs of ancient life. Unfortunately they were yet again beset by crisis when crew members became incapacitated in the simulation. The crew expertly handled the situation as they have many times before and discussed the management and events afterwards with a fantastic debrief. This crew’s final EVA was executed with expert ability and demonstrated their command of the complex material they learned during this course.
