Journalist Report – February 28th

Journalist report, 02/28/17 – Sol 16: Mardi gras.

Today, no EVA was planned in the morning, so that we decided to wake up one hour late. After our sport session, we celebrated Mardi Gras in the American way: eating blueberry pancakes. The day was supposed to be studious: everybody has realised that we now have only three days left, and we all want to end the simulation well. Everything that we wanted to be done by the end of it is now supposed to be well advanced.

Personally, I work hard on the mission video (you may notice a name change). I want it to be quality work and try to do my best on it. Video is probably now the best and fastest was to reach a very large audience, to achieve my journalist goal: make noise, spread the idea that it is possible to work for space exploration without being a 45 years old engineer hidden in a lab, or to make it simple: promote our project and the Mars Society’s. The problem is, I don’t really master video editing, and even if I learn as fast as I can, I am not very productive, even if my efficiency increases every day. It is a pleasure to discover the tools we use to create quality projects, and I was lucky enough to be able to borrow a good video camera from a student association from my school, so that I am very well equipped. I now have already hours of work, and absolutely want to be able to release it before leaving, that is why I will have to lock me in for a couple of hours during the days to come.

At the same time, Xavier and Simon are writing a paper on emergency situations on Mars, and how to deal with it. Xavier is comparing it to sub diving, and Simon to alpinism. This is why, this afternoon, during a short EVA, in which I took part with both of them, after a quick engineering check, I was mandated to shoot new photos of them showing how to assist a victim, while being in EVA, to illustrate their explanations. I was also sent by Louis to test our Optinvent glasses. He was following me from inside the hab, using their video camera, and I was able to record my voice during key moments of the EVA, by using the accelerometer, triggered by a head movement.

Tomorrow, Simon would probably be able to deploy his atmospheric balloon, according to the meteo. This is why we planned a long EVA in the morning. At the same time, I will stay in the hab, filming my last missing shots, and editing our video.

EVA Report – February 28th

EVA #15

Crew members (3) : Xavier Rixhon (EVA leader), Simon Bouriat and Louis Mangin (EVA buddies)

Location: Hab surroundings

Vehicules : None
Time: departure at 1.53pm and back at 2.35pm

Duration : 42 minutes

• Collecting data (water, propane and diesel levels) for engineering reports purpose
• Taking the key from the red ATV and checking other keys were correctly labeled
• Taking the last shots for illustrating our report about emergency procedures and safety  gestures
Summary :
We started with the traditional engineering check (which was the main goal of this short EVA). It was also the chance for me to show other crew members where the propane tank was, next to Shannon’s trailer. Usually, as she’s there, we never go checking it to limit the visual contact with other sources of human life.
After completing the engineering check, we verified the vehicle keys taken off the ATVs and Rovers yesterday were correctly labeled. We also took the key of the Red ATV to secure all the vehicles since the “Deimos incident” 3 days ago. By the way, by now, we never had a look at the Red ATV as we’ve been told it wasn’t working. When we took off the key from it, the key was turned on (on “I” and not on “0”). I have no idea about the issue making this ATV unusable but the battery is probably dead down by now.
We ended this EVA taking the last shots necessary to illustrate our emergency procedures and safety gestures report.

GreenHab Report – February 28th

Green Hab Report  – Sol 16
Report written by: Victoria DA-POIAN (Crew Biologist)

Date : 02/28/2017

Functionality: The heater in the green hab is working well. Today was a very sunny day. I checked the temperature in the GreenHab this morning. It was around 30 Celsius degrees around 09:15 AM while the temperature in the tunnel was around 7.6 Celsius degrees. I switched on the cooler (on stage 2).

The GreenHab temperature was 21 Celsius degrees at 5:30PM while it was 3.5 Celsius degrees in the tunnel. I watered the seedlings this morning and I did this afternoon.

Status: The existing seedlings in the greenhab are continuing to grow well. There are spinach, lettuce, radish, and beans growing very well in the small pots. I harvested one  lettuce and I planted one new.

The Vegidair has been installed 10 days ago and is functionning very well (cf photos). It seems that a sprout in the greenhab has withered and died in the greenhab however all the ones in the vegidair grow very fast.
Unfortunately, there will not be a new crew to take over after us so I am worried about this.


Science Report – February 28th

Science Report

Experiment : Optinvent AR Glasses
Person filling in the report: Louis Maller

I have tinkered some more with Tasker and have therefore managed to implement an interesting function on the glasses:
When you tilt the head to the left, it starts recording what you are saying, and when you tilt your head to the right it stops recording. This functionality was tested successfully during today’s EVA, with the help of Louis Mangin. We have a recording of him giving some information (level of the water tank or propane for example). The voice is clear and understandable even inside the helmet.

The tilt of the head needed is quite strong, the glasses need to be brought to a vertical position, so you have to tilt the body somewhat in order for this to work. I’m currently working to solve this issue.

During the EVA, the glasses and the computer were both connected to the same LAN network created by my phone.  The phone was on the second floor of the hab. I could see on my screen exactly what the person wearing the glasses could see, though with a slight lag. The connection was lost as they went to check the propane tank, when they disappeared behind the small hill. The disappointing thing was that even when they came back close to the hab, I was unable to get the connection with the glasses. I am also trying to solve this issue. It seems to require relaunching the AirDroid App that I am using, which I can also do by using position of the head (for example head tilted upwards works).

Experiment: Seismometer
Person filling in the report: Mouadh Bouyad

I have read the data we collected yesterday, and I think that we have coherent data, especially when it comes to the temperature. I have however noticed something weird : in most of daily measurements, I
obtain irregularities that seem very unnatural to me, almost at the same time (4pm french time).
I wonder if they are not data due to the fact that we sometimes change the key ; however, I can see the same kind of anomaly on other days, when measurements have been made continuously (without changing the key).

Commander Report – February 28th

Dear Earth,

Today we broke the routine and planned a short EVA in the afternoon.
Thus, there was no need to wake up at 7 AM: we began our physical
training two hours later than usual, after a long and restful night.
For the rest of the morning, we did some work, took time for ourselves
and cooked.

The EVA began at 2 PM and lasted only one hour. Its purpose was to do
the engineering check and take more pictures of the emergency
positions that we rehearsed two Sols ago. Simon and Xavier did the
first-aid moves while Louis Mangin was holding the camera.

After the EVA, there was a studious mood in the Hab. Louis Maller
managed to control the Optinvent AR glasses using head movement,
Simon and Xavier selected the pictures for the abstract they are
writing, Mouâdh installed the CCD camera on the telescope and got
familiar with all its operation, Louis Mangin edited the video
presenting our rotation, Victoria helped him and wrote down a set of
suggestions about what could be added or changed in the station, and I
worked on my internship report.

We have three Sols left on this beautiful but deadly planet, so we
have to finish our experiments quickly, before our departure. Luckily,
the wind will be low enough tomorrow to deploy the balloon, it was
right about time!

Ad Astra!

Commander of the serious Crew 175
