General notes and comments: Very fun EVA today because we had a nice long ride out to Skyline Rim, and I was just completely awed by the views. Sam and I each climbed up parts of the escarpment (or the more bougie term: “colluvial fan”) at the bottom of the ridge, trying to touch the layers left by Jurassic forces millions of years before us. Looking up to see the scale of one man compared to that ridge was incredible. Deimos broke 100 hours today– congratulations to our old chap! Young Spirit hung in there and is now at 12h; we’re slowly increasing their battery life.

Questions, concerns and requests to Mission Support:

So part of my experiment explored how to teach the crew to do routine maintenance tasks, such as for the ATV brakes system. This is quite important, due to the safety considerations. I am aware that the ATVs all recently got a complete overhaul, which makes me grateful and confident in them, but I have one question. The brake fluid level indicators are barely readable, through a foggy window, so it’s hard to tell if there’s fluid in there at all. My question is then: were the brake systems checked, during the ATV checkout? Brake fluid is easy to replace, if needed.

Also, thank you all for supporting us throughout our mission! You’ve [CapComms and Mission Support] done a fantastic job at answering our questions and helping us with our concerns (especially reading my long explanations about that darned power system), and I’m very grateful!
