Journalist Report – December 22nd

[Sol 4]

And we are back to red! After 24h of snow and landscapes looking more like Europa than Mars, the sun is shinning again and the temperatures are positive.

Today, we did a short walking EVA to pick up geological samples around the Hab and to see if X-1 is capable of doing it. We brought back a dozen interesting rocks and samples of soil.

Then, this afternoon, we practiced CPR with John to be sure that we would be able to do it if needed. We all managed to rescue Phil the mannequin successfully!

The crew is doing great so far. The only concern is that our water supplies are running low, even though we are careful and didn’t have a shower yet. We discussed tonight how to make it even lower. Hopefully, we will have enough water for the rest of the mission. Think of us when you will have your next shower, it is a dream here!

Greetings from the Red Planet,

Thibault, ExO and spacesuit engineer for the Crew 185

Narrative
I transplanted some more tomatoes and applied Miracle Grow fertilizer to all the plants in the greenhab with the exception of my control and experimental groups of tomato plants. I added tomato cages to the bean plants for some support because that’s the best option I have right now. All the plants are looking healthy.
