EVA Report – April 3rd

Crew 208 EVA Report 03-04-2019

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).

Destination: x516500, y4254500

Coordinates: x516500, y4254500

Participants: Amanda Manget (ENG), David Kim (HSO), Erika Rydberg (GHO)

Road(s) and routes per MDRS Map: Cow Dung Road 0110, to Rd #1572, to Rd #1575

Mode of travel: Spirit and Curiosity

Making It Work On Mars

Today we had a number of successes in our experience and travels here on Mars. We successfully printed another 3D map, we were able to fix our non-functioning 3D printer, and Dean and myself had solid one-hour rides on our bicycle to charge the battery we’re using to power our 3D printer.

David, Amanda, and I had an awesome EVA out to check out an area north of the Hab, where the landscape is called Grey Moon. Did it look moon-like? Well we haven’t visited there yet ourselves, but it was surprising and the color description was accurate. We hoped to find fossils, but instead found only the breathtaking landscape in front of us, which was enough to satisfy us on our journey. The longer we stay, the more the landscape continues to be surprising, surreal, and varied.

A short report for today, but as usual we’re never quite sure what tomorrow will hold.

Sol Activity Summary:

Crew 208 continued 3D printing in the Hab and worked on their research manuscripts.

Useful things to 3D print at MDRS:

Ice cube tray

ENG + HSO + GHO used the Curiosity and Spirit rovers during their EVA to search for fossils.

Crew XO + HSO tried out our Space VR goggles.

Crew XO + GHO each exercised for 1 hour to generate power for our bike-powered 3D printing study.

Look Ahead Plan: Continue 3D printing in Hab and data collection for thoracentesis study in Science Dome. Plan to break sim on Sol 8.
