Journalist Report – April 4th

Date: April 4, 2019

Author: Erika Rydberg

Getting into our Groove on Mars

Food is a central part of our day and that is the case, no matter which planet you find yourself on. Our routine helps guide journey here on Mars, it’s part of the reason why I like to include it in each day’s journalist report. We started the day with cereal and fresh oatmeal. This morning David and Amanda left that for a walking EVA to explore the local fossil beds and discovered many, many seashell fossils close by. We had a large print of a map of MDRS finish on one of our 3D printers, and also printed several useful items today on our other printer. We are also using glow-in-the-dark biodegradable filament to 3D print miniature scale models of MDRS structures designed during our mission to place on our 3D printed landscapes. We performed our daily duties through much of the afternoon and continued to perfect our research. We had a lunch of herbed couscous and smoothies and then, Dean, Julielynn and I left for a second rover EVA mission. Amanda and David stayed behind and continued their journeys on our bike-powered 3D printing project, both putting in an hour riding to charge our battery.

Now that we’re nearly done with our mission, we’re starting to wrap up some of our projects and research. With 3D printing, we sometimes think if only there was more time here on the Red Planet, we would be able to accomplish so much more. For those 3D printer enthusiasts out there, you may know a lot of working with these machines is also about patience and waiting. In the limited time we have we’ve been able to gather quite a bit of knowledge in our processes, projects, and research. We hope you’ve enjoyed taking the journey with us, we have only a few days left, until we blast off and return to our home planet.

Sol Summary – April 4th

Sol: 7

Summary Title: Godspeed, little taters! (in sim)

Author’s name: Julielynn Wong

Mission Status: Nominal

Sol Activity Summary:

Last PM, Crew 208 used our bike-charged battery to power our 3D printer to use biodegradable, food-safe plastic to make a customized mallet finger splint design that was originally printed on the ISS.

Today, Crew 208 continued 3D printing in the Hab, including making a wonderful 3D printed drone map of MDRS prepared by GHO!

ENG + HSO observed many fossil specimens during their walking EVA this AM.

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

Crew 208 broke sim this PM to charge our electric vehicle for the return journey home.

Look Ahead Plan: Continue 3D printing in Hab and data collection for the bike-powered and thoracentesis studies this PM.

Anomalies in work: None

Weather: Sunny with winds

Crew Physical Status: Nominal

EVA: #6 – walking; #7 – Opportunity + Curiousity rovers

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
