EVA Report – April 6th

EVA #8
Author: Arnaud de Wergifosse (Scientist)
Purpose of EVA:
The first part of the EVA is going to be maintenance for the weather station located at 4251250,518500. They will take the rovers towards Pooh’s corner and park them there, then walk 100 meters west towards the weather station. The high winds of today may have caused some damage and the cameras have probably recorded interesting dust formations, we would also like to know if it properly recorded it.
Then, the EVA crew will go back to the rovers parked at Pooh’s Corner and continue towards the North to reach the intersection between Cow Dung Road 0110 and Brahe Hwy 1572. Geological maps indicate this region to be interesting for the discovery of fossils. We will park the rovers there and then perform a geological survey in a radius of a maximum of 1 km around the rovers. We will be very careful of the charge of the rovers and not let it reach below 50% during the trip towards the destination.
Start time: 9:10am
End time: 11:50am
The EVA crew successfully reached the station after having parked their rover at Pooh’s Corner, and it indeed suffered some damage from the high winds that occurred during the last days: the Wind indicator that was replaced during the EVA #4 was ripped off by the high winds. Luckily, it did not fly far from the station and with the use of duct tape, has been successfully repaired for a second time. A quick check of the recording of the cameras showed very good results; the high winds indeed were recorded. After the maintenance on the station was completed, we went back to the rover and drove until the intersection between Cow Dung Road 0110 and Brahe Hwy 1572 for a geological survey of the area. The team first found a big amount of gypsum and collected some samples, and then went out in the search of some fossils. The EVA team searched thoroughly the area and walked approximately 500 meters south-east from the intersection but sadly did not find any fossils. After looping back to the road, the team drove back the rovers to the hab with the samples of Gypsum to analyze later.
