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 Participants: Carl-Henrik Dahlqvist (commander of the EVA), Simon Collignon (medical officer), Chloé Peduzzi, Eléonore Lieffrig

Roads and routes per MDRS Map: Cow Dung Road 0110

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).

EVA #3

Author : Julielynn Wong

Purpose of EVA: Allow Part 107 novice drone pilots to (1) fly a Mavic Pro drone with a standard controller in a symmetric figure of 8 flight pattern; (2) prepare to conduct an outdoor inspection of the MDRS habitat roof under VLOS in a simulated emergency drill

Start time: 14:40

End time: 16:10

Narrative: Software issues led to the amendment of today’s EVA plan. We modified our plan to move ahead on drone flight testing that was planned for later on this mission.

The weather was clear and sunny. We walked halfway to North Ridge (4251500 N / 518250 W).

A demo flight of VTOL, pitch, yaw, roll, and autonomous landing was piloted by XO using the Mavic Pro in Mode 2 stick configuration. ENG then flew the drone, familiarized himself with the flight controls, and attempted to perform a symmetric figure-of-8 while maintaining altitude, and landed the drone. HSO then flew the drone, familiarized herself with the flight controls, and attempted to perform a symmetric figure-of-8 while maintaining altitude, and landed the drone. The drone remained stable despite high gusting winds present during the entire flight.

ENG and GHO then collected soil samples for analysis using soil sieves 3D printed by SCI and HSO. XO performed a test flight for a bird’s eye view inspection of the MDRS habitat for a planned emergency simulation.

We identified the following useful items to 3D print for an EVA at MDRS:

Headset ear piece

Destination: Halfway to North Ridge

Coordinates: Halfway to 44251500 N / 518250 W (North Ridge); our GPS device ran out of batteries and will be replaced by XO
