Summary Title: The beginning of a new week on Mars
Author’s name: Benjamin Auzou
Mission Status: all things running well
Sol Activity Summary:
This morning was a very hard awakening, with the return of the matinal
workout session. After a long breakfast with pancakes, we worked on
experiments : music for plants, spacesuit, water monitoring. In the
afternoon we started the second part of our human factors experiment,
based on a bomb defusal game. The goal is to study the way we cooperate
to solve a given problem.

Look Ahead Plan:
Tomorrow will be very similar to today. Also we hope to be able to go
outside on an EVA to explore and set the LOAC (one of our experiments)
back on the field.

Anomalies in work: none
Weather: windy
Crew Physical Status: all members safe and sound, the shoulder pain of
our crewmember is gone
EVA: Battery replacement of MegaAres, very windy
Reports to be filed: Journalist report, Photos Report, Photo of the day,
GreenHab Report, Astronomy Report, EVA Report, EVA Request
Support Requested: Trashes in the engineering airlock

GreenHab Report – February 24th

Crew 222 GreenHab Report – 24/02/2020

GreenHab Officer : Bleuenn ROIRON

Environmental control : Both heating and ambiant, door open in the
afternoon( window on the door because of the wind outside) to maintain
temperatures between 20 and 25 °C

Average temperatures: 23°C

Hours of supplemental light: NA

Daily water usage for crops: 8 gallons

Daily water usage for research and/or other purposes: 0 Liters

Water in blue Tank: 72 gallons

Time(s) of watering crops: 2

Changes to crops: NA

Narrative:Today, I started as usual by exposing watercress to UV and
music, and then watered plants. This afternoon I went to harvest some
herbs for our pizzas and some carrots that were really good last time.
Our cucumber grow well and I hope we will eat it in a few days and
Spirulina looks really great in one of the aquarium. I went watering
plants again tonight.

Harvest:
Basil: 18g
Sun carrots: 100g(14 little carrots with leaves)
Chives: 7g
Sage: 1g
Lemon balm: 1g
Oregano: 3g

Support/supplies needed: NA

I am sorry for the mistake of yesterday, everything works very well
about environmental control.

Title: Cold wind blows

The wind today has been very loud. There is no visible movement outside
the windows, because there is no vegetation that bends and moves in the
wind. There is only sand and hills that stay still even when the wind
blows. We were impressed by the sheer speed of it: from our weather
station, we recorded a maximum speed of more than 15 m/s! This is rather
good news because wind dries out the mud that the snow created.
Hopefully, we will have dry ground soon, because going on EVA in mud is
very slippery and dangerous.

Today in the GreenHab, Bleuenn showed us a cucumber that’s almost ready
to be harvested. It’s going to be amazing to have a fresh, crunchy
vegetable! Her spirulina experiment is going well, the algae is growing
and will be harvestable in a few days hopefully. Nina’s aerospring moss
is also growing: out of the four plants she chose, three have grown
significantly and she will be able to transfer the moss into the
vertical garden in a few days. All this is very promising!

For a human factor experiment, we played a game called Keep Talking and
Nobody Explodes, about diffusing a bomb. One person has the bomb on
their computer, and they have to work in collaboration with an expert
who has the manual to diffuse the bomb. We are almost becoming competitive!

We ended the day with a delicious spinach pie staring a stunning “Crew
222” decoration by Nina, and watched Kaamelott all together to have a
good laugh before bed.

MDRS ROBOTIC OBSERVATORY

Robotic Telescope Requested (choose one) MDRS-14

Objects to be Imaged this Evening: Keeping on with the research project,
the following targets are added to the queue for the second round, in
addition to the pending observations: NGC 2683, NGC 3031, NGC 2655, NGC
3344, NGC 4449, NGC 4254, NGC 3338, NGC 2775, M100. This will provide me
with standard images that can be compared to the existing reference
images, in order to try detecting a supernova.

Images submitted with this report: None, but the first standard images
are being analysed using the Photoshop overlay function. No promising
finding is to be reported so far.

Problems Encountered: Frames of NGC 4618, NGC 3521, NGC 4725 and NGC
3675 had WCS registration errors which make them unusable for analysis.
New observations are however planned in the coming days.
