Sol Summary – March 6th

Crew 293 Sol Summary Report 06-03-2024

Sol: 17

Summary Title: Here Comes the Sun

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

A very productive day for the entire crew! This morning, our Crew Astronomer was over the moon to hear that the missing part in the Solar Observatory was replaced, and that she could start her astronomy project! She spent most of her morning setting up in the observatory, while the boys’ team was once again roaming Candor Chasma. They decided to return there to re-capture a better quality 3D map for the Photogrammetry experiment, and returned quite content from their outing! They have until tomorrow afternoon to generate the map, an operation which requires a lot of computing power.

A few of Sol 17’s successes: the simulated alarms for the AMI interface are operational, our Crew HSO had a breakthrough in coding her data aggregator for our health data sets, and Léa and I continued working on outreach articles in the afternoon. Established studies are still running smoothly.

Look Ahead Plan:

Two exploration EVAs are planned this week, on Sols 19 (3D team) and 20 (2D Team). On Sol 19, we will request to pilot the drone from the Science Dome.

Anomalies in work: EVA suits 3,4,5,7,9

Weather: Sunny, then mostly cloudy, low 5°C, high 15°C

Crew Physical Status: Nominal

EVA: Photogrammetry at Candor Chasma

Reports to be filed: Sol Summary, Journalist’s Report, GreenHab Report, Operations Report, Photos (6-8 pics), EVA Reports, Astronomy Report

Support Requested: In the coming Sols, there will be random alarms generated by the AMI interface. The Crew has been briefed on how to react to these; most of the time, they will be simple sensor anomalies, but they can turn out to be depressurization alarms. In this case, we will need to perform an emergency EVA to “repair” (i.e. perform a simple task outside to simulate a repair operation) the module.

Therefore, we are requesting the authorization to radio Mission Support when an emergency depressurization EVA is “required” by the interface. These will, of course, only take place when the weather conditions permit it.

Sol Summary – March 8th

Crew 293 Sol Summary Report 08-03-2024

Sol: 19

Summary Title: Martian Topography

Author’s name: Marie Delaroche, Crew Commander

Mission Status: Nominal

Sol Activity Summary:

Today’s exploration of Candor Chasma with the 3D map was a success. All checkpoints were reached in less than an hour, leaving plenty of time to enjoy the beauty of the canyon and take pictures. The walk from the rovers to the chosen photogrammetry site was long, but the EVA was well timed and planned, and the Martian landscapes were worth it. The Crew Scientist, HSO and I returned from Candor Chasma before 1 PM, and we enjoyed lunch with the rest of the Crew.

In the afternoon, scheduling made it so that the Science Dome was occupied almost constantly, rushing the pace of the assessments and experiments a bit. No setbacks were experienced. The Crew Astronomer continued working on their project in the Observatory, while the GreenHab Officer started working on the drone footage shot this morning, at the beginning of the EVA. It looks quite promising!

Tonight, I assisted the Crew Astronomer in repairing the Observatory dome, an operation which proved unsuccessful; we ended up securing the opening with a tarp. Hopefully, we will be able to repair the dome when the sun comes up.

The length and intensity of the mission have slowly started to take their toll on the Crew; we are looking forward, after tomorrow’s second exploration EVA to Candor Chasma, to a restful 21st Sol.

Look Ahead Plan:

We have planned a second exploration EVA to Candor Chasma, involving another team of astronauts having prepared the EVA using the 2D map of the site. A stop will be made at the atmospheric instruments to retrieve the data and change the batteries.

Anomalies in work: NA

Weather: Sunny, Low 2°C, High 15°C

Crew Physical Status: Nominal

EVA: Candor Chasma exploration with 3D map

Journalist Report – March 8th

SOL 19: Martian topography

"And now here is my secret, a very simple secret: It is only with the heart that one can see rightly; what is essential is invisible to the eye." – The Little Prince, Antoine de Saint-Exupéry

The photogrammetry EVA of this morning was a huge success! Even though Mathurin and Yves weren’t fully convinced by the 3D map of Candor Chasma generated by photogrammetry, Lise and Marie found all the checkpoints surprisingly quickly: they went through the 12 checkpoints in less than one hour! They identified yesterday the checkpoints thanks to the 3D map, and prepared the path they wanted to follow. It seems like their preparation was efficient! Even though they were fast in finding the checkpoints, the EVA lasted 4 hours because Candor Chasma is located far from the station, and we had to walk a lot to arrive at the searching site. Assisted by Yves during the EVA, Lise and Marie came back to the Hab exhausted by their expedition, but proud of their performance!

This morning during the EVA, Mathurin piloted the drone from the inside of the Science Dome in order to take pictures of a future path we’ll take on an EVA, and to capture images of the station from the sky! For the seven of us, it was strange to see our living place being so little and seeming lost in the huge Martian desert. On his side, Leo, while he was HabCom for the EVA, meaning he was in permanent contact with the EVA Crew, cooked some pancakes for the Crew. We were delighted to eat them as a dessert for lunch!

Like almost every day, various Crew members did cognitive assessments. For the Orbital Architecture experiment, we perform 3 tests per week and per Crew member, in three different places of the station: the Hab, our major living and working place; the GreenHab, a silent place close to nature; and the Science Dome, a more peaceful working place. Today, there were tests in each module! The tasks we must perform are various, but mostly about concentration, working memory and multitasking.

Finally, at the end of the day, Léa and I prepared tomorrow’s EVA. We’ll go to Candor Chasma as well, but we prepared ourselves with a regular 2D map. It will be hard to counteract Lise and Marie’s performance from this morning!
