Commander's Check-In Report

Ivo Ferreira Reporting

Crew Physical Status: Good

Time Departed/Returned from EVA #2: 17:27 pm / 18:00 pm

Brief Narrative of Field Mission Results: We conducted a series of habitability experiments during the morning.

The rover was tested outside at a small track made for the occasion (an analog of the F1 Cataluña Grand Prix). The first tests were done to study the influence of training on the performance by conducting test with experts and non-experts in the rover operation. Two of the crew members conducted the first of a series of 8 EVAs to study the stress related to communication during an EVA. Their heart rate was being monitored to measure the effect of communication in their stress/physical effort. The mission was a total success.

EVA Data/Interpretations: N/A (To be completed in the following days)

Engineering/Hab Maintenance: N/A

Plans for Tomorrow: Continue with experiments: habitability, rover and drone and EVA to test stress level in the afternoon. Observatory training.

Reports scheduled for today: Engineering, Commander, Journalist and EVA#2

Inventory: None

Support Requested: N/A

Miscellaneous: Today with had our first contact with the Martian species :- ) We got an unexpected visit from local motorbike riders very eager to know about the MDRS. We tour them around and explained some of the experiments and they were really surprised with the Habitat. Nothing like spreading some interest in space related subjects. On an unrelated subject we received several kitchen items and food supplies sent ahead for crew 101.

Today we started the "real" research.

We started the day with Kévin and Jeffrey handling the equipment they slept with to another two crew members. Tonight it will be Audrey and Romain who will have the chance to share their night with a Holter monitor, a temperature recorder and an experimental device to

non-invasively determine parameters such as heart rate, cardiac output, stroke volume, etc. They will be their Valentine for the night.

We shared our saliva with the science community and went on to the first of a series of habitability experiments run by Ayako. In complete isolation we had to smell different fragrances and measure our reaction both subjectively and objectively (more saliva).

The afternoon was reserved to the first teleoperation experiment with Romain as the non-expert user, and Jeffrey as the "Rover-master". There were some differences but both of them managed to complete our We are well below the record on the real Cataluña track… they should update their records database...

mini-F1 analog track (set up for the occasion) in less than 3 minutes.

Later in the afternoon, we conducted the first of a set of 8 EVAs to study the effect of the stress added by communication during an EVA. Kévin and Audrey, conducted a difficult EVA with a lot of constraints with me acting as the Mission Control. They did quite well and managed to save all the crew for certain (simulated) death!

Tomorrow there will be drones flying in the Desert. UFO sightings awaited!

EVA 2 Report

Kévin Theatre Reporting

EVA #2, 17:30- 18:30

Crew Members: Ivo Ferreira, Audrey Lan San, Kévin Théatre

Site Location: Foot: 518135 4250545,518087 4250490,0518153 4250453

Transit Mode: Foot

Objectives: Mission 1 (testing the influence of stress related to communication on an EVA).

Results: Managed to comply with the 2 critical objectives. 1 scientific objective failed.

Lessons Learned: Don't hide too much a so-called sample, else your team won't find it. Good radios are required. It's really difficult to make you understood otherwise.

Journalist Report

Romain Benchenafi Reporting

Third day under the sunny sky of Mars for the crew 100A. We designed a track in order to experiment the Rover's maneuverability, its sensibility to obstacles and the telecommunication interface. A second EVA has been

performed aiming at studying communication related to stress. Time is coming to analyse the results of our experiment and to develop the dynamic of our team. Hope next day will be as good as this one!
