OCTOBER 29, 2018 EVA Report – October 25th 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.
