EVA-10
Deploy the rebuilt radio

Duration: 09:35 - 11:12

Weather: Mostly Sunny; Wind: slight breeze 0 - 09KPH; 08C - 11C

Maximum distance from Hab: 300m

Participants: Wil McCarthy, William Foltyn, Julie Wardlow

Equipment: Volt Meter, wire cutters, wire strippers, cordless drill, Digital camera, protective remote radio cover

Route: The route was from the Hab to the 'Rock Pile' where the MDRS remote radio was installed.

Objectives - Work Done: Objective was to reinstall the remote radio. This has been an ongoing mission. By piecing together the limited resources that are available in the Habitat and on 'Mars'; McCarthy and Foltyn finally coaxed the equipment into a barley function system. Earth resources will be needed from next refit to optimize the needed duplex communication. (SEE ALSO - XO Wil McCarthy's report).

Lessons Learned:

1. Expanding insulating foam makes a great wire casing
2. When walking up 100s of meters it is safer to share the heavy toolbox
3. Prepping all wire connections before deployment save frustration.

EVA-11
Analogous formation search

Duration: 08:33 - 11:44

Weather: Light Clouds; Wind: slight breeze 3 - 11KPH; 09C - 12C

Maximum distance from Hab: 7.8Km

Participants: Jim Russell, Pete Collins

Equipment: ATV tools, Map, GPS, Survival gear, Digital Cameras

Route: North on Lowell Hwy about 7Km around (UTM12 E0519300 N4256200). Turned around and headed south to Cactus Road and proceeded east on Cactus Road to about (UTM12 E0530600 N4251400). Turned around and returned to Hab via northern Old Cactus Road.

Objectives - Work Done: Objectives were to find Mars analogous environments and formations. No new formations were found that were not previously reported on past EVAs.

(See Also Jim Russell's and Pete Collins' reports)

Lessons Learned:

1. You quickly learn safe ATV skills with the right instruction and practice.

EVA-12
Extreme Long range R2-Repeater examination

Duration: 11:45 - 3:49

Weather: mostly sunny; Wind: slight breeze 8 - 18KPH; 09C - 21C

Maximum distance from Hab: 22Km

Participants: Wil McCarthy, William Foltyn

Equipment: Volt Meter, wire cutters, wire strippers, cordless drill, Digital camera, GPS, Maps, Batteries, Survival Gear, ATV tool kit.

Route: This was about a 70Km trek that took us as far west as the western walls of North Canevillle Mesa. Started from the Hab and headed south to Utah SH24. Headed westbound and missed the small semi-paved access road and continued about 15Km more before ruling out that the road was not going to provide the access that was needed. Returned to the needed road at UTM12 0509456E 4246348N. Headed north on the access road to 'Marconi Highway', and then east until the 'T'. Traveled south down Lower Marconi Highway to the bend and UTM 12 513644E 4250901N. At this point it was necessary to stay on the ridge that bears about 32deg north, Carefully wind our way through the delicate desert, trying to stay on as much exposed rock and existing trails as possible and arrive a the peak (5059T UTM 12 515283E 4250986N). After doing a photo documentation and physical inspection, headed back via the same route but in reverse.

Objectives - Work Done: Navigate to the R2 repeater and do a physical and optical inspection. After a long and arduous journey me did just that.

Lessons Learned:

1. Mapping accurate waypoints for long journeys is far more efficient than dead reckoning.
2. It is impossible to capture the grand vistas from the R2 site even with many photos.

EVA-13
Long range navigation and biology sampling

Duration: 3:55 - 18:48

Weather: Light Clouds; Wind: slight breeze 3 - 11KPH; 18C - 22C

Maximum distance from Hab: 7.1Km

Participants: Alex Diaz, Julie Wardlow

Equipment: ATV tools, Map with waypoints marked, GPS, Survival gear, Digital Cameras, Biological sampling containers.

Route: North on Lowell Hwy to Brahe Hwy and then recon to the area of 'Eden'. Then Back.

Objectives - Work Done: The purpose of EVA 13 was to locate water on in the area surrounding the Hab, and to take samples; this was completed successfully. We took the ATVs to 'Eden' (coordinates: N/S 0518365, E/W 4257469) by going along north on Lowell Highway and then west on Brahe Highway. We then took Ptolemy Trail in a northeast direction and then Copernicus highway (northwest) to Eden. Using this route, it took us about 50 minutes to complete the journey to Eden. To begin with, the terrain was fairly flat and with few bends. However, later on in the journey we came across a couple of deep trenches, which we had to navigate through, now I can see why we are using All Terrain Vehicles! The worst of these trenches was about 1.5m deep and appeared to be carved from flowing water (coordinates: N/S 0517474, E/W 4256423), this trench also had a narrow path to it, so low speed and high accuracy were required. But with a bit of time and several wheel spins, we both made it to the other side. The views definitely made the journey worthwhile, and seeing flowing water in such a barren area was a very strange sight. We took water samples and samples of some of the mud and 'salt' features for later analysis.

On the return journey, we decided to take a different route and found 2 anomalous objects; we took the coordinates and a few pictures. The route back to the Hab included Copernicus highway (southwest), to Ptolemy Trail (southeast), to Brahe Highway (west), to Shriaparelli Highway (south), and then and to Sagan Street (west) back to the Hab. This route took longer than the route we took to Eden (at about one hour). The route was also more difficult, as there were more bumps and hills on the track, but it was good training and as the roads were generally higher, so it gave us an overview of the area. The first anomalous object (just a few tens of meters south of the big trench) was a rock formation that looked like a strange arc. It was white and it stood out drastically from the surrounding red soil. The second object (coordinates: N/S 0516639, E/W 4253901) appeared to be two planks of wood, wrapped in metal chains and some ribbon.

Lessons Learned:

1. When driving over rough terrain go slowly and be aware of what is ahead.
2. Be aware of what your other team members are doing.
3. When traveling over bumps, stand up on the ATV to reduce the impacts between your head and the helmet
4. With trenches, drive down slowly using your brakes and use four-wheel drive to get up the other side.
