Journalist Report – April 23rd

Today was our second simulation day. We woke up at 7:30 am and we had breakfast at 8:00. Yesterday, Carl made jam, we ate it, it was delicious. He tried to do choco pasta but for me it was a failure but the rest of the crew really appreciated it. A part of the crew had to go in EVA, but they had a problem with the battery of one of the rovers. The EVA was reported to afternoon.

At 9 am, each of us worked on his experience. Eleonore and Maxime did pictures of the sun with the solar telescope.

At 12 am, Chloé and Carl prepared the lunch. We ate quinoa with beans and corn. After meal, we discussed about Nathan’s experience and his martian constitution. We spoke about the political regime to introduce on Mars.

At 2pm, Eléonore and Maxime baked bread and today it was a success. Julien and Chloé cooked an apple cake, it smells tasty. After that, Maxime, Benjamin, Eléonore and Nathan went to EVA. The rover Opportunity had a battery problem. We had to give up it on the road.

At 6 pm, we prepared the Cap Com. Each of us is working on his report and is going to send it between 7 to 9 pm. After the Cap Com, we will eat a “Gratin dauphinois” with beschamel sauce and pork sausages or lentils for vegetarians. And we will eat the apple cake for dessert.

Like usual, we will do a crew meeting to speak about the day.

EVA Report – April 23rd

Crew 211 EVA Report 23-04-2019

EVA #2

Author: Maxime Bernard

Purpose of EVA: Explore the surroundings in order to find a shelter in case of strong solar winds during another EVA.
Start time:16:00 pm
End time:18:00 pm

Narrative: The aim of this EVA was to explore Cando Chasma in order to find a shelter in case of strong solar winds. Unfortunately no cavity that could be used as shelter could be found. Moreover, we had to let one of the Rover on the road because of a battery failure (position: intersection of Stream Bed connector and Cactus road).

Destination: Candor Chasma

Coordinates (use UTM NAD27 CONUS): Latitude: 4251000, longitude: 521000

Participants: Eléonore Lieffrig (commander of the EVA), Benjamin Flasse (medical officer), Maxime Bernard, Nathan Pechon.
Road(s) and routes per MDRS Map: Cow Dung Road 0110 (2 kilometers towards the west), then Galileo road to reach cactus road. We finally drove half a kilometer towards the east. We then parked the rovers at panel 1104.

Mode of travel: Driving and hiking

Sol Summary – April 23rd

Crew 211 Sol 2 Summary Report 23-APR-2019

Sol: 2

Summary Title: Feeling like a true Martian

Author’s name: Carl-Henrik Dahlqvist

Mission Status: Nominal

Sol Activity Summary: After the daily check-up performed by the HSO as part of his experiment, we enjoy a nice breakfast together. An EVA was planned at 9 am but as the Curiosity rover was not fully charged, we decided to postpone it. Most of the crew members worked therefore on their respective experiments while the crew astronomer and crew scientist got their first shots of the sun. We then worked altogether during the noon break on the writing of a Martian constitution with the crew journalist. During the early afternoon, some crew members prepared the first successful Martian bread. Half of the crew left at 4 pm for the planned EVA to Candor Chasma to look for possible shelters in case of high solar activity.

Look Ahead Plan: An EVA is planned in the morning to get back Opportunity near Candor Chasma and take additional soil samples. Half of the crew will stay at the base to work on their experiments. The crew astronomer will continue to take pictures of the sun in the morning and schedule a few observations with the Celestron telescope to get images from quasars. This will allow her to infer their luminosity and determine the evolution of their activity. The rest of the day will be devoted to the experiments.

Anomalies in work: No issues.

Weather: Hot, bright and sunny all day.

Crew Physical Status: Good, yesterday’s twisted ankle is less painful.

EVA: The aim of this second EVA was to explore the Candor Chasma region and look for caves. Underground structures could indeed be very helpful to protect the crew from solar wind/radiation in the case of increasing solar activity and CMEs (Coronal Mass Ejections). Unfortunately no caves have been found and we lost Opportunity near Candor Chasma. We’ll try to get the rover back during tomorrow’s EVA.

Summary of any observatory issues: Nothing to report

Summary of health and safety issues: Someone slightly twisted a bit his ankle while climbing down a ladder on the upper deck. Not really a problem.

Questions, concerns and requests to Mission Support:

* The hot water heater does not seem to work. Water does flow into the hot water pipes and taps, but keeps being cold.

Perhaps a problem with the propane supply ?

* The pump that flows from the loft tank to the taps seems to be leaking. The cardboard on the ceiling of the rightmost room is getting wet.

It looks that at least one previous crew was aware as we found a few sponges placed under the pump.

We fear that some long-term damage could happen to the cardboard and the wood that is immediately underneath it.

Additionally there is electric wiring up there, and water could enter in contact with it.

* I doubt that we will have enough water for the whole mission. We are trying to limit our consumption, but as a crew of eight even drinking water represents quite a cost.

Journalist Report – April 22nd

Today was our first simulation day. We woke up at 7:30 am and we had breakfast at 8:00. We ate cornflakes with dehydrated milk and orange juice. A part of crew started the day by gym while others did the housework. The first floor is now clean.

At 9 am, each of us worked on his experience (read the scientist’s report for more information).

At 10 am, Maxime and Eléonore tried to use solar telescope but were only able to use it in manual mode. After that, Eléonore and Simon prepared the lunch. We ate chiliconcarn with pasta. It was delicious. After meal, we had free time.

At 2pm, we continued our experiences. Each member find a place to work. At 4 pm, Carl, Eleonore, Simon and Chloé went to EVA to explore Mars. Chloé took soil samples for her own experiment.

At 5:15 pm, someone was on ladder when he twisted his ankle. But he seems better now.

At 6 pm, we prepared the Cap Com. Each of us is working on his report and is going to send it between 7 to 9 pm. After the Cap Com, we will try to make sushi with basil from the greenhouse. At the end of the day, we will do a crew meeting to speak about the day.

Science Report – April 22nd

Crew 211 – UCL to Mars

Submitted by Science Officer Maxime Bernard

Commander Carl-Henrik Dahlqvist

Our commandant started to assemble the structure of his CubeSat that he printed prior to his arrival on Mars.

XO Officer

Simon started to build his wood stands on which he is going to fix his antennas.

HSO Officer Benjamin Flasse

This morning Benjamin gathered the data from the sleep monitoring he did on Eleonore.

Right after that, he measured everybody’s weight, tension and brain awakeness.

In addition to that, he took measures like fat density,bone quality and water repartition intra/extra cellular using Biody Xpert to monitor our body evolution along our stay here.

He spent the rest of the day making the inventory of what was available in the first aid kits. Most of the compresses were outdated and others were opened. The purchase of new medical supplies should be prioritized and more info will be available in one of the upcoming HSO reports.

Crew Astronomer Eleonore Lieffrig

Our astronomer was able to use the solar telescope for the first time today in manual mode.

Crew Engineer Julien Amalaberque

He is checking the parameters of an Intel RealSense D435i depth camera in order to evaluate which amount of stream data the positioning algorithm will be able to handle without being overwhelmed.

Crew Biologist Chloé Peduzzi

She spent the morning one the science dome preparing her culture medium in which she adds strains of spirulina.

She then disposed them in the greenhouse under two different light conditions before realizing it was way too hot in there. Therefore, she instead disposed them into the Science Dome. She encountered another problem we she realized she was sold the wrong transformer, 240V to 120V instead of 120V to 240V.

She went on EVA in the afternoon with three other crew members to gather soil samples.

Crew Journalist Nathan Pechon

Today, Nathan started to ask us questions about what we thought would be a good juridical baseline of a martian colony.

He then worked on the data he gathered during our talks to work on his first law article about what type of political regime should be adopted on Mars

Crew Scientist Maxime Bernard

Still waiting for the delivery of his muon detector that should have arrived on the 19th of April… The parcel seems to be somewhere between Salt Lake City and Hanksville.
