Purpose of EVA: Change batteries of LOAC and MegaAres, and then explore a martian like area

Start time: 8:58 AM

End time: 11:25 AM

Narrative: We went out in the morning at 9:03 am after the depressurization. Florian couldn’t start the ATVs 1 so we took two ATVs and Perseverance.

We changed the batteries of LOAC and Mega Ares and left for exploration at 9:30 AM. Then we left the rovers and we were really happy to see a beautiful landscape for the last time on Mars for us so we took the most of this EVA.

We came back to the HAb around 11 :19

Purpose of EVA: Changing the batteries for MegaARES and LOAC. Exploring Candor Chasma.

Start time: 08:59 AM

End time: 11:25 PM

Narrative: The purpose of this EVA was to change batteries from MegAres and LOAC and to explore Candor Chasma. We used the ATVs 1 and 3 and the rover Perseverance. Nothing to report during the change of the batteries. The exploration was awesome, a bit tired. We walked for approx 8km, up and down the Canyon. According to the footsteps, we went further than last crew so we’re proud of it. Everyone went safe and sound.

EVA # 6
Author: Luc Fortin (Engineer)
Purpose of EVA: Change the batteries for MegaARES and LOAC. Install the
solar oven. Test a protocol for a soundless EVA.
Start time: 09:09 AM
End time: 11:20 AM
Narrative: This EVA was very special for us as it was a soundless one.
So I made an extensive briefing before entering in the airlock to make
sure everybody (including the Habcom of course) had the protocol
(detailed in the EVA request) in mind.
The five minutes (09:09 – 09:14 AM) of depressurization were the
opportunity for each of us to think about their upcoming actions and
tasks. We walked out of the airlock, Aurélien installed the solar oven,
while Clément and Marion checked the 3 rovers, and I checked the level
of water in the static tank. Then Marion, as communicator, was in charge
to communicate through the window all our data to Valentin, the Habcom.
She did it successfully.
Then we drove to the LOAC and MegaARES with one passing between rovers 1
and 2 that went smooth. In 5min, we change the batteries of the 2
instruments, still without a word ! We leaved the place at 09:33 AM and
arrived at Reservoir Dam 11min later. The protocol for the rover ride
was very efficient and safe for both teams.
We walked to the Reservoir which was almost empty. Then we decided to
walk East in the canyon. Landscapes were really amazing. Was also the
opportunity for us to test our communication protocol, especially the 1
to 5 scale, used to know how each EVA team member feels. It was
efficient, but we found that it can be improved. Because two members
answered 3 out of 5 for the fatigue but during the debriefing, we
noticed that they had a really different interpretation of that number
(one was about to ask to go back home, while the other one was almost
ok). So we need to clarify what does each number correspond to, to make
sure we all have the same reference scale.
We leaved Reservoir Dam at 10:57 AM, and arrived at 11:10 AM in the Hab
zone. As planned, the Habcom was waiting for us, looking through the
window with binoculars. He gave us the approval to park the rovers near
the RAM. Marion once again was in charge of communicating the rovers’
data to the Habcom. We brought back the solar oven and entered in the
airlock at 11:15 AM for the 5 last minutes of silence of the day !
It was an interesting experience for all of us, and it was the
opportunity to demonstrate that this type of protocol is efficient and
usable in case of loss of all our radios during an EVA !
Destination: Reservoir Dam.

EVA #5
Author: Clément Plagne
Purpose of EVA: Change the batteries for MegaARES and LOAC.
Familiarising ourselves with the terrain and the hiking required for
exploration of the environment. Testing the recently repaired suits.
Start Time: 09:07
End Time: 11:04
Narrative:
We left the airlock at 09:12, a bit later than planned. Checks for rover
status and water level went nominally. Valentin was tasked with testing
the Honda ATV, that had failed to start previously – attempt was a
success and Valentin reached first gear to confirm ATV was running.
We reached the LOAC/MegaARES area at 09:20, and battery replacement
tasked went nominally as usual.
We took off for North Ridge and parked the ATVs near Stream Bed
Connector, heading west by foot. We witnessed a helicopter making a
close approach near us and kept going. We hiked through steep terrain,
trying to make our way to the top of the Ridge but stopping due to
safety concerns.
Our hike lasted for a bit less than an hour, going from hilly, red-hued
hills to rockier zones, to gray, nearly Moon-like zones. We decided to
leave earlier instead of attempting a tough looking climb in a rocky area.
We arrived back near the hab at 10:56, and were back in the airlock by
11:04. All suits worked perfectly.
Destination: North Ridge.

EVA # 4

Author: Marion Lebrun (Scientist)

Purpose of EVA: Change the batteries of MegaARES and LOAC. Explore a bit
further the surroundings of our Martian habitat and have a look at a
different kind of relief of the planet.

Start time: 8:50 AM

End time: 10:48 AM

Narrative: After the five minutes of depressurization, at 8:55 AM, we
walked out of the airlock. We checked the water level of the static tank
as well as the charge and usage duration of all 3 rovers. We wanted to
take the ATV Honda but we could not get it to start so we ended up
taking rover Spirit and ATVs 1 and 3.
We drove to our first stop which was right by the Hab where the LOAC and
MegaARES were set, to change the batteries of the two instruments. As we
were very organized, by 9:13 AM all the procedures were done and we
could leave for Candor Chasma.
We parked the vehicles before Steam Bed Connector and started the
exploration towards our final destination. The walk lasted about 35min.
It was quite surprising to see how sandy the area was. We also found
water on Mars during that EVA as well as antelope footsteps. The canyon
was truly beautiful and we were happy to find shade under some rocks
since it was getting really hot and sunny.
At 10:00 AM we decided to turn around to make sure we will on time at
the Hab. Unfortunately, on the way back, I lost my headset after
Aurélien tried to adjust my backpack that was hurting my back and my
neck. I had just enough time before I lost it to give the lead to Luc
who became the EVA Leader for the rest of the EVA.
We arrived at the place where we had left the vehicles at 10:31 AM and
we came back to the Hab at 10:43 AM to start the five minutes of
pressurization.

Destination: Plane area near the Hab along Cow Dung Road and the East
side of Candor Chasma

EVA # 3
Author: Blandine Gorce (XO)
Purpose of EVA: Change batteries of LOAC and MegaAres, and get a good view of our planet Mars from Hab Ridge

Start time: 9:03 AM
End time: 10:34 AM

Narrative: We walked out of the Hab at 09:08 AM after the five minutes of pressurization. We took the rovers to go and change the batteries of Mega Ares and LOAC. We were really organized and at 09:28 we had finished the procedures for the two measure instruments, so we came back to park the rovers next to the Hab.

We then started the exploration towards Hab Ridge, we walked a little bit next to the Hab and then we started to go up the ridge. It was not too hard because the soil was very dry and it was not too hot yet. When we arrived the top, the view was beautiful and we were really happy
to see the campus from there. We then decided to use Hab ridge road to go down the hill. we took the road close to North Ridge so we could get a good view at North Ridge which was beautiful.

We decided to come back early because the backpack were hurting a bit the back of one of us. We came back at the Hab at 10:29 AM to start the 5 minutes of pressurization.

Destination: The flat place next to the Hab and Hab Ridge
