Crew 206 EVA Report 01-MAR-2019
EVA #4
5
Author: Benjamin Auzou
Purpose of EVA:
The EVA is built to continue our exploration of different regions of
MDRS area. This one will be done without vehicule and so with only three
astronauts. We will climb to Hab Ridge by the 1103 path. Once up there,
the purpose will be to go through Hab Ridge Road and Sagan Street
intersection, to walk along the ridge and to arrive at Hab Ridge. On our
way we will make a stop to take picture of our home from Hab view North.
During the EVA we will also walk around the station in order to spot
degradations after the snowstorm.
Start time: 9:00 am
End time: 10:52 am
Narrative: Today, we went pretty fast on our EVA preparation like
yesterday, so we left the hab at 0900, instead of 0915, as it was
planned. Starting from tomorrow we will reconsider our preparation time
to leave the Hab at planned time.
That was our first EVA with an odd number of members, that was
unsettling for the preparation time, since we are usually working with
pairs (Team Blue and Red) for security checks. For the rest of the EVA
that change was less disruptive because of the absence of rover travels
and the good cohesion of our EVA team.
After the usual checks (Water tank for Team Red, composed of me, and
rovers states for Team Blue, composed of Cerise and Gaspard), we walked
around the MDRS campus in order to spot eventual degradations. The only
thing we spotted was a piece of tarp from the corridors that has been
moved by the wind. At 0907, all checks had been done and we started our
walk to Hab Ridge.
Looking for the road 1103, we stumbled upon a large black tarp (see
attached picture) at the coordinates 518418/4251029 (read on the GPS).
On the climb to Hab Ridge, the path was still muddy and slippery, even
if the surface seemed dry. However we managed to pay attention to each
other and walked safely toward the ridge.
After a couple minutes being amazed by the geologic diversity of the
landscape, we continued our walk to our goal : Hab View North.
We arrived at this point at 1002. We spent 10 minutes here enjoying the
view and taking some pictures of the Hab from the ridge.
Then we decided to return to the Hab following our steps in the opposite
direction instead of trying to go directly down the ridge. Safety first !
We arrived at the station and entered the airlock at 1047.
