EVA # 22

Author: Nicolas WATTELLE

Purpose of EVA: Dismounting of our outdoor experiments’ devices

Start time: 9:32

End time: 10:27


EVA participants checked the rover batteries just in case. The obtained information is:

Perseverance: Usage Duration – 228.6 Battery Charge – 100%

Spirit: Usage Duration – 157.7 Battery Charge – 100%

Opportunity: Usage Duration – 87.1 Battery Charge – 100%

Curiosity: Usage Duration – 171.1 Battery Charge – 100%

Nicolas, Marine, Elena and Matheo went to the atmospheric experiment location by rover. They arrived at 9:40. They dismounted the different devices, and brought them back to the Hab, using rovers, at 9:57.

Cerise the Habcom, after depressurization, took the devices inside the Hab.

Then, by foot, Nicolas, Elena, Marine and Matheo went to the antenna location. There, they dismounted the antenna.

They were back at the airlock with the instrument at 10:22.

Depressurization ended at 10:27.

Destination: Intersection between Cow Dung Road and Entrance Road. The atmospheric experiment devices are set up in a circle of radius 2 m. Behind the Hab, where the antenna is set.

Sol 18 – End clap

Author: Nicolas Wattelle

That’s it, we’re preparing to definitely leave this beautiful red planet… It is a mix of many different emotions: joy, sadness, the first impulses of nostalgia even if we have not yet taken off …

The day was dedicated to tidying up. First, for the trip outside, the morning outing was meant to dismount our external devices. In order, MegaAres, PurpleAir, LOAC, weather station, and HF antenna. It was a last EVA strangely filled with emotions: we carried out rotations throughout the mission to ensure their maintenance, for us it was inked in the routine; yet this morning we removed everything and tomorrow we will no longer have this daily appointment. So, we took advantage of it, the weather was good, we took a few last photos in our suits… Our goodbyes to the Martian ground that we have been walking on for the last 3 weeks.

Then it was the time to clean the Hab, to prepare the field for the next crew who will take over on Sunday. Our personal and work affairs, the sports equipment… It is true that, at the end of these three weeks of mission, our stuff was a little scattered all over the Hab: we used to the maximum the space which was dedicated to us.

At each device dismounted, it was an opportunity for us to remember the moments we spent here. Experiments in the ScienceDome, the few remaining plantations in the GreenHab, the radio set up in the Lower Deck… Some activities went well during this journey, others did not work, sometimes we know the reasons, sometimes not… This is the game of sim. We will have the opportunity to go over all this once back on Earth, but whatever it is we are getting out of here happy with the mission as a whole, and the group is more united than ever by all these adventures: We have lived together on Mars for 3 weeks!

PS: To prove to you that the weather was good, take a look at today’s Sun’s picture taken by our astronomer Marine. The observation conditions were really nice: you can spot Sun flares on the surface!

Sol Summary – March 11th

Crew 263 Sol Summary 11-03-2022

Sol: 18

Summary Title: Safe return on Earth

Author’s name: Cerise Cuny

Mission Status: Nominal

Sol Activity Summary: This morning, during EVA we were able to disassemble the atmospheric experiment and the HF antenna, quite quickly. Valentine did the last session of the Human Factors Experiment. The rest of the day was dedicated to tidying and cleaning the Science Dome, the RAM and the Hab.

We were very moved to live our last moments on Mars. We broke the sim at 5:44pm. After enjoying Earth’s gravity and feeling the air on our skin, we jumped into the Crew Car to have burgers in Hanksville. We were getting less and less inspired with the dehydrated food, so we found the burgers particularly tasty. It was also kind of emotional to talk to strangers.

Look ahead plan: Tonight, we will stargaze and tomorrow morning we will go watch the sunrise. After that we will do the last of the cleaning and head back to Grand Junction.

Anomalies in work: None

Weather: Clear sky.

Crew Physical Status: Very good.

EVA: EVA 22 and EVA 23 in the morning, nominal.

Reports to be filed: Sol Summary, 2 EVA Report (n°22 and 23), Operations Report, Journalist Report, HSO Report, Astronomy Report, Mission Summary.

Support Requested: None.
