Further, Faster, Stronger

For the second time of the simulation, there has not been a sport session this morning. But this time, that was not because we reached a break day. No, the team just was not able to wake up early enough. Yet we did not stay in bed until noon either! We indeed had an EVA planned at 9am, so we had to hurry! For the first time, neither Louis nor Victoria would be a member of the EVA. Laurent, Benoît and Jérémy made up the team, while I was their leader. We made our usual at our instruments to change the LOAC batteries. However, we realized that the batteries of the MegaARES were also at a dangerously low level. We had to go back to the Hab to ask Gabriel whether we had to change it too, yet he declined, as he believed that could be done tomorrow. We could then go on with the core of our EVA: exploration.

As we were going further north than we ever went before, we decided to ride the ATV: one of each one of us! These ones are indeed way faster and more pleasant to drive than rovers. As we did not bring any heavy material on EVA, there was thus no issue not having rovers. After a 20 minutes’ drive, quite longer than we were used to, we finally arrived to the canyon we aimed to visit today. This canyon was a bit special: he was divided in several stratums under the one we parked the ATV on. The entry of the canyon was decorated by a display panel about dinosaurs, whose fossils are likely to be found here. Not the most Martian of the things we have seen here, but it is yet quite cool to know that! We then tried to enter the first level of the canyon: it has been a bit hard to find a way down at first, but after some researches we finally discovered an easy one. This small trip is the canyon was really nice, even though it revealed to be tiring! We found some small caves where Benoît and I could take a break in, while Jérémy seemed to have borrowed Benoîts lure for small beautiful stones. Once we completed our trip to the depths of the canyon, it was almost time to ride our ATV back to the Hab!

The return trip was outstanding. To be able to drive a lonely vehicle in such a beautiful landscape, the sensation of the ATV rolling over rocks, everything was delightful. But this moment could not last forever, and the Hab quickly appeared in our eyesight, ready to welcome us. Or at least, that is what we thought. We indeed got no response from the Hab: Gabriel, today’s HabCom, remained silent. 10 minutes later, we decided to go back to the instruments to get the empty batteries we left there, not to be cluttered on our ATV. But as we came back, Gabriel finally responded! Yet, it was to ask us to go back where we came from, and turn off the MegaARES… This was however useless, as the MegaARES was already shut down because of the low battery. Gabriel was by the way worth some derogatory remarks because of this meaningless return trip. Remarks we finally regretted when we discovered that our communication issues were due to the walkie-talkies, which stopped functioning.

Our today session of KTNE was quite less successful than the previous one, especially for Benoît and Louis, which were not able to find a specific word in a list of 25 in 3 minutes, and they had several difficulties counting up to 4, which led to some loud funny shouting matches. And today was also the day I could (finally!) take my first shower! I also was able to beat the best score of the crew, going down to 1.2 gallons for my shower. It is hard to say that we had almost lost the habit to smell nice here. This shower was yet really pleasant, and my hair is at last not standing anymore on its own!

Journalist report, 02/28/18: Already mid-rotation!

Today is already our 10th day of mission, which means we are overpassing its half. Altogether, this pivotal day has been rather quiet. No EVA was indeed planned for today. After our daily sport, most of the crew went to the GreenHab in order to replace the tarp, which protects plants from the sun, as it was turned in the wrong direction. A task which was rather hard to achieve: the temperature inside the GreenHab is indeed 100°F in order to preserve plants health, sweating the team. In the late morning, both teams succeeded in each situation of KTNE, which seems to become too easy for us. Jérémy had yet less success in his own experiment: he suffered web connection issues, and Benoît could thus not drive the rover. While Louis and Victoria started an additional sport session, making the team question their sanity, Benoît and Gabriel wanted to live a new culinary experience and decided to mix bread dough with food coloring. The obvious result: bread sharing his color with Smurfs. A black market of food is also starting to be organized inside the Hab, through

As half of the mission is already over, it is time to draw a first review of our experience. Our daily life has indeed suffered a dramatic change since our arrival at the station! To take a daily shower: over. To do the dishes after each meal: over. To eat lavishly: over. To take a break outside anytime we want: over. To be able to contact our close relatives anytime we want: over. To be able to be totally isolated: over. We had to become used to any of these situations! Everyone seems to have its own hardest lack to deal with, yet the separation from friends and family is often he hardest, and then comes the food, then the lack of fresh air. We learned to save almost anything: from food to water, from our oxygen during EVA to our energy during sport session. For the moment, no one has for example taken more than one shower! And those were not the kind of shower that is usually had: we keep the falling water in a large basin to use it to rinse ourselves! The food rationing might be the hardest for the team: even each member of the team was near to come undone since the beginning of the mission! However, only 9 days of mission are remaining, it is up to us to continue to work along the same lines!

Journalist report, 02/27/18: In case of emergency

As today’s EVA was planned on the afternoon, our sport session was delayed by one hour. Yet I obviously forgot to change my alarm clock, and I was the only one to be woken up at 6.30am. Hopeless to get back to sleep, I decided to wait for our evil session: the 3 times 20 second mode was back today. However, it seems that the workout benefits to everybody. We indeed all beat our personal scores in nearly every exercise: Louis for example could do 70 push-ups, Jérémy was able to deliver 90 half-squats, while I was capable to do 85 lunges, all in 1 minute. Laurent even succeeded in making 104 head shakes, though real crunches would have been better. After around 10 days in the station, we are all getting in a better shape: each one lost about 2 to 3 pounds of fat!

The day was dedicated to emergency procedures. Our health and security officer Laurent prepared us a 2 hours briefing on the morning. He explained at first the good habits to have when one finds someone injured. What is the most important is to make a statement of the situation: if the place still can be dangerous, what the causes of the incident are, how the victim is behaving. Gabriel was the one to play the victim for a while: he was repeatedly placed in recovery position and was flipped over onto his back. After these global gestures, Laurent became more specific in his showing. We are not in a Martian simulation for nothing! In such environment, these gestures would indeed be mainly practiced through spacesuits… Some gestures are indeed becoming much more complex: in the case of a vertebrae issue, it would be impossible to maintain the head because of the helmet. Cardiac massage would be compromise, and even acknowledge if someone is breathing or not becomes a hard task. Finally, even repatriate someone to the station would be problematic: with our spacesuits, everyone is 20lbs heavier, and there is no solid hold on it.

Laurent was thus leader of today’s EVA, where he would be able to try these procedures on the outside in real conditions, along with Louis, Jérémy, Victoria, Gabriel, Benoît. Jérémy and I would be the only two to guard the fort. While Victoria, Gabriel and Benoît made a short detour to our instruments, in order to change the battery of the MegaARES, Louis and Laurent dealt with some small tasks around the Hab. While the other half of the team came back shortly after, they were ready to go on with the procedures. Victoria seemed to quite enjoy the recovery position, as she has often been in this situation. The team dealt with a lot of different situations and diagnosis, in order to cover a large amount of the injury possibilities that could one day happen into space. In the meantime, I served as HabCom for the team: I was their referent inside of the Hab, harvesting the data they give me about the resources of the station, such as water level, the state of our vehicles, etc. They finally came back into the Hab after only 2 hours, as they had completed everything they wanted to do.

Our evening was punctuated by our traditional KTNE session, which is becoming increasingly harder: instructions are now incomplete in each manual, and teammates have to be coordinated in order to be able to succeed. Gabriel also gave us the first ranking: Victoria and I are at the moment on the top, yet things will certainly change rapidly, as the hardest part is to come! Benoît also seems to be getting some issues dealing with food: while we split our remaining energy bars yesterday between the crew, he already ate almost half of them! It will be hard to keep going like this until the end of the mission!

Journalist report, 02/26/18: Water on Mars?

As most of the crew became increasingly hungry over the days, Benoît, with the help of Jérémy, decided to make pizzas. That was not an easy task using only dehydrated products! However, along with some seasonings that Jérémy brought back from the GreenHab, those pizzas were literally amazing, and to go to bed with a full stomach was deeply appreciated!

“Wake up”! This time, I was indeed not woken up by my alarm, that I forgot to put back after our day off, but by Victoria, knocking on my door. After a resting day for our muscles, it was time to go back to sport, and to bring back our body aches. An EVA was also planned for today. And for the first time of the mission, neither Louis nor Victoria would be EVA leader! Jérémy was the one to lead today, accompanied by Gabriel, Victoria and me. We made a short stop at our experiments, in order to change the LOAC battery. However, the voltmeter seemed to have caught a cold, and could not give any information. Jérémy thus almost confused the battery to take back to the Hab with the battery to plug to the LOAC. After having gone further and further north since the beginning of the mission, we decided to travel south this time. However, our map played a few tricks to us, and we had some troubles finding the place we wanted to go to.

We finally arrived at the rim of the canyon we wanted to visit, and we made a small detour in order to be able to get into it. We discovered here something we did not think we would find in such environments: some large bodies of frozen shallow water. Jérémy could not prevent himself from walking on one of them, yet he rapidly stopped when he realized that some cracks began to initiate. After having completed our trip in the canyon and having taken some photos, we went back to our vehicles, and we decided to go back home. This has been a quite short yet very nice EVA!

As our reserves of pasta and rice are starting to decline dangerously, we now have to assault our stock of beans, surely nourishing, but still a lot less tasty. As usual, we spent a lot of our afternoon time playing “Keep talking and nobody explodes”: the difficulty is now way higher (Louis quite notably paid the price) and our team have been split up, leading to some misapprehension and misunderstandings.

Journalist report, 02/25/18: First day off / Special edition 1: About the LOAC

On day off for the entire team today: no sport or EVA, yet we remain on simulation, and everyone did work a bit on their experiments or on other tasks. Benoît, Laurent and I helped Jérémy transplant carrots in new pots, while Louis finished his work on our encouragements video for our schoolmates preparing their apparition in famous French show “Questions pour un champion”. The rest of the day has been a complete break for the team, before the beginning of our second week of mission: Jérémy and Gabriel have had the luxury to take their first shower today, whereas Laurent and Benoît already took one. Only Louis, Victoria and I still did not have that opportunity. But that does not imply that we are covered by dirt! We indeed wash ourselves daily with disinfecting wipes, which is nonetheless an appreciated comfort.

As I do not have so much more to tell about the crew today, I will explain the purpose of the experience hidden behind the strange name LOAC, as this name has already been quoted several times in my reports. The Light Optical Aerosol Counter (LOAC) is used to measure the air’s concentration in aerosols, which are fine particles in suspension. It gives the size distribution of these particles as well as an indication of their typology (carbon, minerals, salt, liquid, etc.). The purpose of this experiment is to use the instrument in different conditions to get new measurements and analyze their meaning. Two types of measurements will be harvested : outdoor ones, to get information about the airborne dust, and indoor ones, to see how the air quality of a confined space changes according to the activities crew members are having (cooking, changes between day and night, particles brought back from EVA, etc.).

Such particles have indeed an important impact on a planet’s atmosphere, mainly on its climate, but also on human health, the most obvious example being carbon particles, which can stick to lungs and cause severe damages. We have still a lot to learn about Martian atmosphere, its composition and chemistry. This type of instrument has indeed never been used in any space mission before; it would thus give unprecedented science results on another planet’s atmosphere! It is also a great tool to control air quality in a confined space, because of its small size and low consumption as well as the precision of its measurements. Considering a long term space mission, this is an important factor that needs to be controlled; it could prevent disastrous catastrophes and allow a full-time survey of air quality. As you already know if you read some of my reports, we had lots of difficulties in deploying the LOAC, mainly because of its alimentation, yet it is now fully functional!

We would like to thank Jean-Baptiste Renard, research supervisor at CNRS (French main scientific research center) and developer of the LOAC, for having accepted to lend us this instrument, and for his trust in us for its use.

Journalist report, 02/20/18: First scientific and gastronomic hitches

Our first own made bread prepared by Victoria was welcomed after such a long day we had. Though it was somehow a bit compact, it was yet tasty, and with some strawberry jam it made a nice dessert! After having filled our stomachs, it was yet time to go to sleep, to prepare for the second day of mission.

And sleeping early was crucial, as today’s sport beginning time was 7am … Some of our fellow crew members wore their nicest outfits : Benoît put on his shirt of Paris Saint-Germain, while Gabriel chosed the winning combo : fitted black shirt and (very) fitted flashy yellow legging. However, the sport session was shortened for the ones who would go on EVA: Gabriel, Jérémy, Benoît and Commander Victoria were the ones to go out this morning. The EVA followed the purpose of the last one: it was now time to place the measurement instruments, after having chosen the location, according to our observations of the previous day.

However, everything did not work as we expected. The team took a lot more time to be ready than they thought, as they had a lot of material to bring on the rover. The team first went placing the instrument of Jérémy’s experiment, the LOAC. Though it was perfectly working in the Hab, it did not give any result on the outside. After a small check, the team realized the alimentation was broken, and that they had to bring back the LOAC to the station to fix it. The second instrument, Gabriel’s MegaARES, took almost 2 hours to the team to be placed. Gabriel had indeed some issues with his helmet, which started to be covered by fog: he was blinded, and had thus to give instructions to the others members of the EVA team, which was not an easy thing to do. The team learned that some tasks which were usually easy became nearly impossible wearing a spacesuit: to tighten a lonely screw took the team over half an hour, yet they finally succeeded with the help of a perfect teamwork. At the same time in the Hab, Louis wanted to follow Victoria’s example in baking new bread. However, he realized later that he did not put the ingredients in good quantities (especially because of American cooking units, which Louis was not happy to be forced to use).

After the team got back in the station, Jérémy was happy to find 3 red cherry tomatoes in the GreenHab : our first fresh products from there. Those were not really large (especially the one we named Victoria), yet it did not reduce our satisfaction. The afternoon was slower: Benoît learned to play French game “coinche”, but he and Jérémy lost nonetheless in a large way against Louis and Victoria. As we reached the middle of the afternoon, Louis’ bread was finally ready. Yet, even though it looked at first more like a Martian rock than like a French baguette, it was quite comestible after all. It was then time for Gabriel and Jérémy to launch their human factors experiments. However, they suffered some software issues, and so were not able to make their first tries today: these will so normally begin tomorrow. These missed tries conclude a day full of small issues, yet things will certainly get better as soon as tomorrow!

Dear all,

Here is the Journalist report, 02/19/18: a first step on Mars

Our first evening at the Hab had been festive: Victoria had baked a cake for Louis’ birthday, which occurred a couple days earlier, but which we did not have the time to celebrate. Our two commanders then organized a table tour, letting each one describe what he expected from the mission, what he wished to do here and what he was afraid of. After this long discussion, it was time to go to sleep, except for Louis, who still had to prepare the physical exercises for the next morning.

And these were hard exercises: so hard indeed that Laurent began to feel sick in the middle of the crunchs, and that Gabriel would certainly have vomited if his stomach was not empty, as we even did not take our breakfast yet! While the crew had begun to feel knock-out, breakfast was finally welcomed after such energy usage. Put back in shape, the crew was now able to end the preparation of experiments on the morning, before the first EVA which would occur in the afternoon.

Laurent, Jérémy, Commander Louis and I were the ones to leave the Hab on the afternoon. The EVA had two main purposes: to explore the surroundings of the station, and to find perfect places where we could place Jérémy and Gabriel experiments, as these needed special weather conditions. After having put on our spacesuits, radios and helmets, it was time to say good bye to Victoria, Gabriel and Benoît, and to enter the pressurisation airlock. 3 minutes later we could open the door, and finally discover the Martian landscape. I went down the stairs, and had the luck to be the first one to make a step on this land.

After having accomplished some minor tasks around the Hab, we could ride the rovers to a further land. We stopped at different points along the road, in order to find out the right places to put the measurement instruments for the diverse experiments, and also a mushroom-like rock to show our support to our fellow students of ISAE-SUPAERO which were selected to participate to famous French show “Questions pour un champion”. On the last part of the EVA, we chose to climb up the plateau over the base, in order to get a better view of the base region. And what a view it was, even though I almost lost one of my lungs to get there! As Jeremy took some last pictures, Louis started to struggle finding a way down, and we took a bit more time going back to the rovers. The EVA was near its end, and we went back to the Hab, freezing cold on our rovers because of the wind. We went back to the airlock, waited for the pressurisation, and could finally come into the Hab, and put off our wet suits. One thing for sure, sleep would not be hard to find after such a tiring day!

Voici la version française du rapport du journaliste, 19/02/18 : un petit pas sur Mars

L’ambiance était à la fête à l’étage du Hab pour cette première soirée de la mission : si nous n’avions pas pu fêter l’anniversaire de Louis le jour même à cause de l’enchaînement des événements, nous nous étions rattrapés ce soir, et Victoria avait même cuisiné un gâteau au chocolat pour l’occasion ! Nos deux commandants furent ensuite les instigateurs d’un petit tour de table, afin de savoir ce que chacun attendait de la mission, et quelles étaient nos envies et
appréhensions. Après cette longue discussion, il était temps pour tous d’aller dormir, à l’exception de Louis qui allait nous préparer une séance de sport aux petits oignons le lendemain matin.

Et pour du sport, ce fut du sport. Entre Laurent qui a commencé à sentir la nausée monter au milieu d’une série de crunchs, et Gabriel qui aurait sûrement rendu son petit déjeuner si nous l’avions pris avant la séance, l’ambiance n’était plus vraiment très festive. Alors que l’équipage commençait à se sentir KO, le petit déjeuner fut vraiment une délivrance après une telle dépense d’énergie. Remis d’aplomb, l’équipage était enfin d’attaque pour terminer la
préparation des expériences dans la matinée, afin d’être parés pour la première EVA (sortie extra-véhiculaire) qui aura lieu dès
l’après-midi.

Laurent, Jérémy, notre commandant Louis et moi-même avons donc été les premiers à quitter le Hab. L’EVA se décomposait en deux tâches principales : explorer les alentours de la base, et trouver des endroits où déployer les expériences de Jérémy et Gabriel, qui nécessitent des conditions climatiques particulières. Après avoir difficilement enfilé nos combinaisons, radios et casques, il était l’heure de saluer Victoria, Gabriel et Benoît et d’entrer dans le sas de pressurisation. 3 minutes plus tard, nous pouvions ouvrir la porte, et nous découvrions enfin le paysage martien. Restait 2 marches à descendre, et j’ai eu la chance d’être le premier à fouler cette nouvelle terre.

Après avoir accompli quelques tâches mineures autour du Hab, nous pouvions chevaucher les rovers et nous éloigner de la station. Nous nous sommes arrêtés plusieurs fois au bord de la route afin de rechercher l’endroit parfait pour déposer les instruments de mesures des diverses expériences, aussi un rocher en forme de champignon pour supporter nos camarades de l’ISAE-SUPAERO sélectionnés pour passer devant Julien Lepers. Nous nous sommes éloignés un peu plus dans la dernière partie de l’EVA : nous avons décidé d’escalader le plateau qui surplombait la station, afin de bénéficier d’une vue globale sur la région. Et la vue valait le coup, même si j’ai failli perdre un de mes poumons pour y parvenir … Et alors que Jérémy prenait quelques dernières photos, Louis semblait avoir quelques difficultés à se remémorer le chemin du retour vers les rovers, qui a donc pris un peu plus de temps que prévu. L’EVA touchait à sa fin, et nous étions à nouveau sur la route du Hab, aveuglés par la buée sur nos casques et frigorifiés par le vent qui s’inflitrait sous nos combinaisons. Nous sommes donc rentrés dans le sas, avons attendu la pressurisation, et nous sommes finalement rentrés dans le Hab, où nous avons enfin pu retirer nos combinaisons humides. Une chose était sûre, le sommeil ne sera pas dur à trouver après cette journée éprouvante !

Journalist report, 02/17/18 and 02/18/18: last moments on Earth

Louis had been the last to join us at Grand Junction, picked up by Gabriel, glad of his time of arrival. The mission was finally on its way! After a final brunch at the hotel, Victoria made a stock of bananas (which would be over even before we could see the Hab), it was time to leave civilization! The target: Hanksville, in the deepest paths of the Utah desert.

A journey not so comfortable at last, especially for Laurent, who carried the large MegaARES instrument that Gabriel left him. Nonetheless the road met its end, and we were getting deeper in the desert, towards the Hab. A few turns between giant red rocks later, we finally were able to see the station, among its little brothers, the laboratory, the GreenHab and the observatory. To welcome us, no previous crew was present contrary to the usual, but new stairs were being done, which will reduce falling risks and avoid injuries. It was then time for Shannon’s first briefing, completed with some advices from Attila the Peruvian, yet hard to understand because of Jack the dog, which seems to be into his teenager crisis.

Following a small cleaning session imposed by Victoria, it was now time for all of us to choose our rooms. Well, except for Gabriel, who inherited of the small bed under the celling, in order to take care of the hydraulic pump. A small rover/ATV trip later and we were taking our first meal in the station! A meal which finally revealed to be quite tasty: lyophilised ingredients are not so terrible. However, the crew started to feel really tired and everyone went to sleep to prepare the last pre-mission day!

A sleeping night which was short for Benoît and Louis, who had to bring back the location car to Grand Junction: it is an early morning for them! A few hours later, the remaining members of the crew tasted their first Martian breakfast with powdered orange juice and pancakes … powdered pancakes. The morning is used to put in place experiments which will be completed during the whole 3 weeks, and to finish some secondary tasks, like patch sewing, realized by Victoria, myself and Benoît for diverse results …

As both drivers came back from their journey and everyone filled their stomach, it was the time to take crew pictures! Despite some difficulties (one dog which repeatedly entered the field of view, and a tragic fall of the camera on the ground), photos were nonetheless satisfying. A last rover/ATV trip was organized, which proved to be quite hard due to continuous strong blowing winds and small dust storms that came with it, leading some members of the crew (especially Gabriel) to steal the look of a grandmother with his bandana.

The fatidic hour was near: while Shannon gave us her last advices, we prepared ourselves to the closing of the Hab door. Here begins 3 weeks without seeing the Sun without the helmet. As Shannon wished us good luck and left us, Gabriel finally grabbed the door handle to close the main door. After a few videos and pictures were taken by Jeremy, it was at last time to start the simulation.

6.05pm: the Hab door is closed, here begins the mission
