EVA Report – March 18th

EVA #8 Report– 18th March 2018 – Sol 7

Crew members: Frédéric Peyrusson (EVA leader), Maximilien Rirchald, Sophie Wuyckens, Bastien Baix, Mario Sundic

Objectives:

  • Soil samples for Maximilien’s experiment.
  • 3D mapping for Bastien Baix.
  • Pictures

Sample positioning for Frédéric’s experiments.

Operations:
14:15 – Entering the airlock
14:21 – Samples positioning of Frédéric’s samples close to the station
14:29 – Leaving the MDRS with the 3 Rovers
14:41 – Arrival at Yellow Moon for pictures, sampling and 3D mapping with the drone. The weather was windy and the drone wasn’t stable enough for mapping
15:09 – Leaving of Yellow Moon
15:18 – Second stop in the road towards Green Valley. Some pictures in front of the beautiful Skyline Rim
15:23 – On the way back to MDRS
15:47 – Arrival at the Hab. We tried to fix the Deimos’ wheel and helped Sophie install her detector.
15:53 – Entering the airlock
15:56 – Mission finished

Narrative:
Our EVA#8 took place on SOL 7 at 14:15. I am Frédéric Peyrusson and I wanted to be part of this EVA in order to place samples of Bacillus subtilis in closed chamber outside. Samples were prepared during the morning.
The weather was quite windy and cold today. Fortunately it was less cloudy than in the morning. We arrived at Yellow Moon at 14:41 after a tough trip. Bastien tried to use his drone for 3D mapping but it wasn’t stable enough. We took soil samples for Maximilien’s experiments. We also saw a lot of motorbikes tracks in the hills.
We then moved towards Green Valley, made some great pictures for our website in front of Skyline Rim, and went back to MDRS. We tried to fix the Deimos rover, but the tools didn’t fit. The EVA finished at 15:56.

Vehicles

  • Opportunity, Curiosity and Spirit rovers

Journalist Report – March 18th

The Mars Desert Research Station is an ever-expanding project. Initially composed of only the main Hab and a GreenHab, new modules have since been added. A solar observatory (the Musk Observatory), an automatic night telescope, solar panels, the Repair and Assembly Module, as well as the Science Dome which has allowed the laboratory to be moved from the restricted lower deck of the Hab to a brand-new area with lots of space to work. Among our researchers working in the Science Dome are Ariane and Fred, both experts in microbiology.

Ariane is a molecular biology graduate, currently beginning her doctorate in the field of genetics. Her experiment, despite being centred on microbiology, is of great importance to the whole crew: she is making Martian bread! Indeed, we may imagine a situation in which we would run out of yeast on Mars, leaving us unable to make one of our favourite staple foods. To keep the bread production sustainable, we would need to get the yeast, lactobacillus, from elsewhere, and that is exactly what Ariane is doing: she is isolating it from human saliva! This is no easy task. First, she sampled saliva and cultivated the many microorganisms it contains in Petri dishes. These Petri dishes were supposed to be filled with what we call a selective medium – a substance which only allows for the growth of a specific microorganism, in this case, lactobacillus. Unfortunately, the shipment from Earth which carried this medium has had an accident, and hasn’t been able to reach us in time. Ariane therefore had to rely on her knowledge of microbiology to manually isolate and cultivate only the required yeast, and no other micro-organism – no easy task, given their very close resemblance! She is currently very close to achieving her goal, and the rest of the crew very close to eating our first true Martian bread (made, in part, from spit)!

Fred, on the other hand, is a biotech and pharma graduate, currently pursuing a doctorate in bacteriology. His fist experiment, concerning plant culture in Martian regolith, has been covered below. In addition to this, he is also working on a microbiology experiment, aiming to evaluate the survival capacity of bacteria in the harsh conditions that exist on Mars. He is using the bacterium bacillus subtilis, a very common microorganism, and placing it in small quartz vials (a material which allows UV rays to pass unhindered), in different conditions around the station to see how many of them will survive. At the end of the experiment, these bacteria will be counted and their numbers compared to a standard sample which will have been staying in the safety of the Science Dome. This experiment is especially interesting because it sets out to answer many questions about the ability of earth-born bacteria, which are therefore adapted to earth-like conditions, to survive in an environment that is literally alien and extremely aggressive. If conclusive, a positive result could mean that the Martian environment is suitable to harbour Earth’s microbes, which could mean many things for agriculture, human life, development, terraforming, and generally our future on the Red Planet.

Non-nominal systems: Ventilation cover fell.

Notes on non-nominal systems:

Due to the extremely hard winds of the last days, the cover of a ventilation opening above the kitchen fell. We found it on the ground near the GreenHab. As you can see on our self-made 3D model enclosed to this mail, it is high. We don’t have a ladder long enough to fix it.

Commander Report – March 18th

Today, it was planned to have a day off to relax, make the food inventory, clean up a bit the station and leave on EVA. After waking up, Michael and Sophie began a gym session while others were just relaxing up to midday. After that we had a Sunday lunch composed of mashed potatoes with chicken and compote. Our bellies being fully filled up, five crew members left for an EVA towards “yellow moon” to take soil samples, pictures and exploit the drone (see EVA report). Unfortunately, the weather was too windy and as a consequence it was impossible the fly with the drone. We came back to the Hab at 15h47 and we started to clean our living place. Shannon came to spoke with us about tracks found in the desert. This morning we have seen motorbikes and probably ATVs riding off road.

Tonight we will have the dinner and a board game time to strengthen the team spirit.

Concerning the food inventory, we will need some food supplies. It would be really appreciated if a space ship can bring us these food supplies.

Regarding the station, a part from the MDRS aeration felt. During the EVA, we tried to dismantle the wheel of the broken rover. Unfortunately, the tools provided do not fit.
