Solar: The battery bank does not hold charge when sun is down and low on the horizon. Inverter Slave 1 and 2 went offline and do not restart, which limits us to 5kW when on solar.
Main generator has been monitored for oil leaks; minor leaks observed, need to add oil every 2-3 days. Generator is limited to 8kW, see previous reports for details.
Main generator:
1) Oil, oil filter and air filter changed on 02/19/2025, 8507.7 hours.
2) Current hours – 8555.9.

Problems Encountered: Thanks for your previous message! No problems
today, the conditions were pretty bad, very cloudy so not detailed. Is
there also a best time to look out for prominences during the day? They
are almost absent since the beginning, I hope it is because the sun is
not very active right now.

Journalist Report – February 22nd

Crew 311 Journalist Report 22Feb2025
SOL 6: The Sky Is No Longer the Limit!
Author: Isolde Louzier-Ricalens

12:30 PM: This morning was quite athletic for half of the crew. Meddi, Quentin, Célyan, and Somaya conducted an EVA not only to change the batteries of the atmospheric instruments but also to take the first drone photos for our stratigraphy experiment. Yes, with a drone! The whole group headed towards HAB Ridge, a high-altitude plateau offering a stunning view of the station and the desert. They were able to observe the station from the sky, whether through the camera in their hands or the drone hovering above them. But such a hike requires a challenging path. To reach this plateau, the small team had to make their way along the side of the mountain, a challenging journey that made their return a relief. Erin and Robin worked on the code for AMAIA and the Core Data experiment for data recovery. Personally, I was transferring audio files to the EvolSan lab while serving as HAB Com for the EVA. This role involves coordinating between the EVA crew, those remaining in the station, and mission support; it is very important for safety reasons.

When the small team returned, we went to greet them and help them carry their equipment and de-gear. Between the first aid kit, the two batteries for the atmospheric instruments, the drone, the water bottle bags, the camera bag, not to mention the heavy suits, there are plenty of kilos in an EVA; a little help upon arrival is always welcome.

2:48 PM: Today is Saturday at the station. Meddi trained the entire crew on maintaining the GreenHab so they can take over when he is unavailable. Currently, everyone is busy completing their last tasks before the afternoon break, which will mark the start of the weekend for the MDRS. On the agenda: crochet, Lego, anecdotes, and tasting the cereal bars I baked this morning.

EVA Report – February 22nd

Crew 311 EVA Report 22-02-2025
EVA # 04
Author: Célyan Ferret, HSO
Purpose of EVA: Installation of sign to deter tourist from touching LOAC
(aerosol counter), MegaArès/Field Mill (electromagnetic field sensors)
and the weather station.
Collect data from LOAC and MegaArès/Field Mill. Then collect geological
data with a drone along 1103 road by foot and then along Hab Ridge road
direction North if we have the time.
Start time: 9:00 AM
End time: 11:58 AM
Narrative: EVA Crew entered the HAB Airlock at 08:55 AM and left the
station at 09:00 AM. Somaya and Quentin took the Curiosity rover and
Célyan and Meddi took the Perseverance rover. We arrived all together at
9:18 AM at the atmospheric instruments (518250 E, 4250750 N). We
collected the data, plant the signs and take pictures. We left to go
back to the station in the rovers. We arrived at the station and started
to walk for the stratigraphy experiment at 10:30 AM. Once at sufficient
high we started the drone (3.4076453465201, -110.7928409212195 :
coordinate of the location tracker at the lower deck) and took pictures
and videos. We walked all the way up to Hab Ridge and we arrived at
11:19 AM.
Once all the pictures and videos taken for the stratigraphy and the
communication we went back by foot to the station. We entered the HAB
Airlock at 11:58 AM.
Destination: Marble Rituals, Going back to the MDRS and then Hab Ridge
Coordinates (use UTM WGS 84): 518250 E, 4250750 N (Atmospheric
Instruments) then 518100 E, 4251600 N (Stratigraphy)
Participants: Célyan Ferret (HSO and EVA Leader), Meddi Moumouni (Green
Hab Officer and having the legal papers to fly the drone), Quentin
Berlemont (Crew Astronomer), Somaya Bennani (Crew Scientist)
Road(s) and routes per MDRS Map: Cow Dung Road 0110 for the atmospheric

Sol Summary – February 22nd

Crew 311 Sol Summary Report 22-02-2025
Sol: 6
Summary Title: The sky is no longer the limit!
Author’s name: Erin Pougheon, Crew Commander
Mission Status: Nominal
Sol Activity Summary: This morning, Crew HSO, Crew Astronomer, Crew Scientist and Crew Astronomer went out on an EVA. The aim of the EVA was to retrieve data from the atmospheric instruments and to change their batteries, and then for the EVA crew members to walk around the station, towards Hab Ridge. The EVA was successful, except for some problems with the atmospheric instruments: it seems that they didn’t take data for all the time they were outside on Mars… We’ll analyze the data and see!
Meanwhile, inside the station, Crew Journalist was HabCom for the EVA and took time to cook and copy files from the EVOLSAN recording session of yesterday. Crew Engineer worked on debugging AMAIA and helped Crew Commander with Core Data handling.
After a well-deserved lunch, everyone accomplished some tasks in the beginning of the afternoon, and then stopped around 4:00 PM and enjoy the beginning of the weekend in the station! LEGO building, crocheting, reading… The activities are restful!
Look Ahead Plan: On Sol 7, Crew 311 will enjoy a little more sleep in the morning and wake up at 8:30 AM. The crew will take advantage of the weekend day to have a larger sport session of an hour and then clean the station deeply. The afternoon is planned to be restful for everyone.

MUSK OBSERVATORY
Solar Features Observed: Sunspots, prominence
Images submitted with this report: 3
Problems Encountered: Thanks for your previous message. I am getting
better with the tuners. I am however frustrated with how better the sun
appears on your tutorial with only a good focus compared to what I can
see even after tuning, changing the exposure etc. I linked a screenshot
of your video so you can see the difference with exactly the same
parameters. I need an good amount of post processing with gimp to get to
the level of your raw image. Is there something I am missing here?
