Crew 211 EVA Report 25-04-2019

EVA #4

Author: Simon Collignon

Purpose of EVA: Explore the Special Region in order to explore and search for ancient martian life.
Start time: 09:00 am
End time: 11:00 am

Narrative: The aim of this EVA was to explore the Special Region as said in the purpose section of this EVA report. Unfortunately, the rover SPIRIT was discharging too fast, the battery’s autonomy was not high enough to reach the Special Region. Therefore, we decided to stop on Cow Dung Road at the intersection with Galileo Road 1104. After a short exchange with the Hab, we decided to take Galileo road and explore the area delimited by Cow Dung Road, Galileo Road, Cactus Road and Stream Bed Connector. Sadly, there were no sign of ancient Martian on this area. Next time we’ll try to reach Special Region

Destination: Galileo Road 1104

Coordinates (use UTM NAD27 CONUS): Latitude: 4252000, longitude: 519500 (Intersection of Stream Bed Connector and Cow Dung Road)

Participants: Carl-Henrik Dahlqvist (commander of the EVA), Simon Collignon (medical officer), Chloe Peduzzi, Nathan Pechon.

Road(s) and routes per MDRS Map: On Cow Dung Road from Hab to the intersection with Galileo Road 1104. Then we took Galileo road1104 and stopped 500 meters after.

Mode of travel: Driving and hiking

EVA #3

Author: Simon Collignon

Purpose of EVA: Taking back the rover opportunity to the MDRS and exploring the surroundings of the hab.
Start time:09:00 am
End time:10:30 am

Narrative: The aim of this EVA was to reach the rover opportunity which had a battery failure yesterday on Cow Dung Road in order to drive it back home. After the rover’s rescue, we’ve explored the surroundings of the MDRS in order to have a better understanding of the geology near the Hab.

Destination: Intersection of Stream Bed Connector and Cow Dung Road, Hab View North.

Coordinates (use UTM NAD27 CONUS): Latitude: 4251500, longitude: 519000 (Intersection of Stream Bed Connector and Cow Dung Road)

Participants: Carl-Henrik Dahlqvist (commander of the EVA), Simon Collignon (medical officer), Chloe Peduzzi.
Road(s) and routes per MDRS Map: On Cow Dung Road from Hab to Stream Bed Connector then on Cow Dung Road from Stream Bed Connector to Hab. After parking the rovers at the hab, we walked around the MDRS towards North and directly turned towards West in order to reach the Hab View North.

EVA #2

Author: Maxime Bernard

Purpose of EVA: Explore the surroundings in order to find a shelter in case of strong solar winds during another EVA.
Start time:16:00 pm
End time:18:00 pm

Narrative: The aim of this EVA was to explore Cando Chasma in order to find a shelter in case of strong solar winds. Unfortunately no cavity that could be used as shelter could be found. Moreover, we had to let one of the Rover on the road because of a battery failure (position: intersection of Stream Bed connector and Cactus road).

Mode of travel: Driving and hiking

EVA #1

Author: Eléonore Lieffrig

Purpose of EVA: Exploration and collection of soil samples

Start time: 4:30 pm

End time: 6:00 pm

Narrative:

We have had our first EVA this afternoon which lasted for two hours. We travelled to the hills on the left of the Cow Dung Road between the Robert’S Rock Garden and Zurbin’s head to take a few soil samples to be used by Chloé, the GreenHab officer, for one of her two experiments. The EVA went very well and the sunny weather allowed us to take some beautiful pictures of the Martian environment surrounding the MDRS.

Destination: Latitude: 4248000, longitude: 519000 (UTM NAD27 CONUS)

EVA #7

Author: Julielynn Wong

Purpose of EVA: Geologic exploration and drone flying

Start time: 1430

End time: 1630

Narrative: Our EVA Team confirmed the battery charge on the Curiosity and Opportunity Rovers was 100%. GHO drove the Opportunity rover with COM as the lead vehicle for the EVA. At 82% charge, the Opportunity engine stopped at 0517574 4256201 and could not be restarted. After waiting approximately 40 minutes, the Opportunity rover was restarted and continued until 0518227 4250731 before stopping again at 72% charge. Our EVA Team was able to reach David who came out with an ATV to tow the Opportunity rover back to the Hab.

EVA # 5

Author: David Kim

Purpose of EVA: Geologic exploration

Start time: 1030h

End time: 1300h

Narrative: Drove Curiosity and Spirit to destination through planned route. Arrived at Gray Moon and walked around area collecting Martian soil samples and took pictures. Returned without issues. Noted that Spirit originally drained its battery quickly from 98% to 80% in less than 5 minutes during normal operation. However, this normalized and drained slower after 80%. All normal rules and operations followed (Back Wheel Drive, Normal speed, Normal gear).
