Commander's Check-In Report

Ivo Ferreira Reporting

Crew Physical Status: Good

Time Departed/Returned from EVA:

EVA #14 (09:30-10:00),

EVA#15 (14:35-15:04),

EVA#16 (15:33-15:57),

EVA#17 (17:30-18:00),

EVA#18 (17:00-18:20)

Brief Narrative of Field Mission Results:

During the morning we finished the habitability experiments and conducted an EVA to collect extra samples on P2 (N38.40746º W110.79280º) and P3  (N38.40737º W110.79261º) by foot for our cooperation with the Vrije Universiteit of Amsterdam. The samples consisted of small rocks and soil taken at different positions and at different depths and will be sent once we get back to Europe along with the ones for the ESTEC and the SALM group in Reunion.

The afternoon was reserved for another 4 EVAs, 2 EVAs as part of the experiment to monitor the effect of communication-induced stress on an EVA (both by foot), another EVA to get more details on the P3 position (by foot) and finally another EVA by ATV to collect samples at the location C4 (N38.40545º W110.78573º, AKA Dino site near the Habitat - near a pale green vertical fossilized tree trunk) and location P6 (N38.42638º W110.78342º).

Hopefully tonight there will be some time for star observation in the small mountain near the Habitat.

Engineering/Hab Maintenance: GreenHab system is working. water has been manually pumped but needs some time to get through the straining tank to be fully operational.

Plans for Tomorrow:  Continue with more EVAs to test the influence of stress induced by communication on the EVAs, explore the possibility of using the range extender with the parrot.

Reports scheduled for today: Engineering, Commander, Journalist, Science, EVA #14, EVA#15, EVA#16, EVA#17 and EVA#18

Inventory: N/A

Support Requested: We only have about 1.5 containers of gas left for the ATVs. Consider bringing some gas during crew change over.

Miscellaneous: N/A

Commander's Report

Digging Mars

After finishing the last habitability experiments we now have a lot of time to perform EVAs. We are becoming "EVA experts" here on Mars, today we managed to complete 5 of them: two to continue the communication-induced stress, and 3 more to collect extra samples for the ESTEC and the Vrije Universiteit of Amsterdam.

The engineers back on Earth did a great job designing our Hab but what we really like is to be outside to be able to do some science and at the same time enjoy the magnificent landscape of this planet.

During the afternoon alone, we did the two EVAs with simulated emergencies and gathered about 2 kg of samples at different locations (don't worry there is still a lot of sand, rock and dirt here on Mars), and for this we mostly used the ATVs.

They are also great pieces of engineering. They allow us to go faster, further and spend much less energy that would otherwise turn our experience into an Extremely Violent Activity. Some would say they look like the quads on Earth but they are much more fun. As we get more used to them we find that every trip that is more than a few hundred meters away is a good excuse to use them...

The afternoon ended with Audrey testing the range of Max (which was already missing us) with and without the the range extender. We have to get to the bottom of the problem and understand why it does not seem  to work when the camera is broadcasting. We understand that Max is a lady and she wants her privacy.

Tonight we will enjoy some curry rice and hopefully stare at the sky, the weather is clean so we can probably see Earth from here tonight.

Science Report

Ayako Ono Reporting

1. Habitability Experiment: Today is the final day for the experiment to be performed with stimuli. This morning, Ivo, Kévin, and Ayako discussed about color wheel, first. Currently, we cannot use printer with our laptops because of the version, and I decided to use a package of crackers and color cards as freshwater checker, instead of color wheel. I took a picture of materials as color gradation strips together with them and white paper. Please see the attached file. I will try to take these photos under ideal white light, sometime soon, so that I will be able to adjust the color of color gradations, and it will work instead of color wheel. After the discussion, Audrey performed with “Copy and Mirror” as neutral stimulation, which is not so interesting task as copy, and Kévin performed with color strips. Also, habitability questionnaire, as digital file, were offered to all crew members to be filled in. End questionnaire and debriefing are scheduled on 24th Feb.

2. Also in the morning, Audrey and Romain worked on Audrey’s related tests about human factor in tele-operation. She already had a track with a rover, and she tested with the rover and drone, if it improves the situation, as assistant to get information, or not.

Thanks a lot for the suggestions to adjust colors for habitability experiments. They were very helpful and I really appreciated it. Now, you don’t have to send color wheel.

Journalist Report

Romain Benchenafi Reporting

Two days left now before the shift of crews.

As usually we were very busy, with five EVAs today.

Now we are playing UNO all together to finish this day, wishing Jeffrey could have been with us.
