GreenHab Report – March 1th

GreenHab Officer: Adrien Tison

Environmental control: Heater

Average Temperature: 69.1 °F

Average humidity: 27%

Hours of supplemental light: 0 hour

Daily water usage for crops: 8.45 gallons

Daily water usage for research and/or other purposes: 2.11 gallons

Water in the blue tank: 138.17 gallons

Time(s) of watering for crops: 9:15

Changes to crops: N/A

Narrative: Today, as it was neither sunny nor hot, plants and crops didn’t suffer from heat and looked better. I still watered them well and took care of everything.

I noticed that the aquaponics system loses a certain amount of water in the long term. Indeed, mine is quite small so if you consider water loss due to the cycle, water volume decreases over time. I then added 2.11 gallons of water to the fish tank to ensure their safety and well-being for the following days.

However, the system is doing well, and you can easily notice how well the lettuce is growing!

Harvest: N/A

Support/supplies needed: N/A

Sol Summary Report – March 1th

Crew 275 Sol Summary Report 01Mar2023

Sol: 17

Summary Title: Saving Private LOAC

Author’s name: Jeremy Rabineau, Commander.

Mission Status: Nominal.

Sol Activity Summary:

The weather surprised us again today and we had to cancel our exploration EVA to Candor Chasma, initially planned in the morning. When it stopped snowing, Mission Support agreed to let us put on our spacesuits to quickly change the batteries of our atmospheric instruments and retrieve the LOAC device, as it is very sensitive to precipitation. With the rainy afternoon that we had, we were indeed happy that the LOAC was safe within the Hab!

All these changes in the schedule give additional work to our Crew Scientist, who is responsible for planning our scientific activities. At least, we all hope that the ground will soon be dry so that we can go back on EVA, especially during the visit of the BBC on Friday (Sol 19).

Today, we have finished equipping everyone with the tracking system, so that we are aware of our position at anytime of the day and correlate this with other information. We have also continued the human factors protocols, as well as the tests of the ultrasound device based on virtual reality and artificial intelligence.

Look Ahead Plan:

We would like to reschedule today’s EVA at Candor Chasma. The plan would be to have a first EVA on Friday (Sol 19) and another one on Saturday (Sol 20). The EVA crews will have to find specific checkpoints based on a 2D map or a 3D render, respectively. We would like to take the opportunity of these EVAs to change the batteries of the weather instruments, since they cannot last for more than two days, especially in cold weather.

The BBC is planned to arrive at the MDRS on Friday (Sol 19) between 8:30 and 9:00. They would follow us on our EVA to Candor Chasma, then film inside the station in the afternoon, and leave at around 17:00.

Anomalies in work: None.

Weather: Rainy, low 0°C/32°F, high 8°C/46°F.

Crew Physical Status: Optimal.

EVA: The objectives of EVA #14 were changed due to the bad weather conditions. This EVA will have to be rescheduled.

Reports to be filed: Sol Summary, EVA Report, Operations Report, Journalist Report, GreenHab Report.

Support Requested: None.
