EVA Report – February 27th

Crew 263 EVA Report 27-02-2022

EVA # 7

Author: Nicolas WATTELLE

Purpose of EVA: Atmospheric Experiment maintenance (batterie change, MegaAres Setup)

The atmospheric experiment includes 5 devices: LOAC (Light Optical Aerosol Counter), an Electrical Field Mill, Purple Air (Aerosol Counter), Mega-Ares (Electrical Field Counter) and a Weather station. The aim of this experiment is to do testing of Martian-Atmospheric Study Equipment and their maintenance by human operators. Performing their maintenance and set-up while wearing spacesuits and following EVA protocols is the purpose of the experiment. All devices are located at the same place.

Batteries for the LOAC, MegaAres, the Electrical Field Mill and Purple Air needs to be changed daily. Hence, during this maintenance EVA, the 3 batteries (the Field Mill and MegaAres use the same battery) needed to be replaced.

Start time: 08: 58

End time: 09:55

Narrative: EVA Participants entered the airlock at 08:58. Depressurization ended at 09:03. EVA participants checked the rover batteries just in case. The obtained information is:

Perseverance: Usage Duration – 228.1 Battery Charge – 100%

Spirit: Usage Duration – 157.2 Battery Charge – 100%

Opportunity: Usage Duration – 84.7 Battery Charge – 100%

Curiosity: Usage Duration – 168.7 Battery Charge – 100%

The EVA participants arrived at the Atmospheric Experiment location at 09:10. The 3 batteries were replaced. Marine was in charge of changing LOAC battery, she did it without any problem to declare. Nicolas changed the Purple Air and Electrical Field Mill batteries, and tried to recover data. But there, while taking out the waterproof protection, condensation appeared inside the box. Then it was impossible to turn it on again. Matheo set the MegaAres antenna, the installation went well, the measurement started correctly.

Nicolas’ radio moved out from his ear at 9:19, but stayed inside the helmet. He could still hear the radio, but had to make efforts speaking to be heard.

At 09:46, the participants left the atmospheric experiment location.

Journalist Report – February 26th

Sol 5 – Allo… do you copy?

Author: Nicolas WATTELLE

Today we missed a rendezvous. In the context of the HF propagation study, we were supposed to contact a different “Martian base” in Toulouse. There, the radio club REF 31 should have gathered ham radios and pointed its antenna towards the MDRS.

Remember, on Sol 3 we set up the antenna near the Hab. During the following day, we set up the indoor setup: an ICOM transceiver, an antenna adapter, and a computer, linked to our triangle of steel. We did some tests, we received signals from around the planet, so we were hopeful for this morning’s session. But our experiment does not depend only on our work, another big factor named “The Sun” has also its part of the responsibility.

Mars (as Earth), has an atmosphere made of different layers. Among them, one, in particular, allows long-range propagation: the ionosphere. This layer is sensitive to Sun activity (solar storms, eruptions…), and can accumulate electrical charges. And if the total charge is significant, it permits HF waves reflections, and considerably increases the range of radiocommunications.

On Earth you might be able to perform intercontinental contacts, only using basic antennas and transceivers: a ground-ground communication without any satellite or other facility between the source and the receiver. It would be an interesting technique to use between ground stations on Mars!

So, we tried during the last months to set this experiment with the radio club (we will also perform beacon listening during the upcoming days to characterize the propagation following the propagation during the days), and today was the first attempt.

The protocol was one hour long, testing different modes of modulation, from the more reliable to the less reliable one. But the Sun might not have had enough activity the previous days: we faced a sad silence. We issued calls, but we received no answer. Have we been heard in France? We don’t know yet. But we will twice again before our mission ends, another case to follow!

That was the first experiment of the day for Valentine and me. For the rest of the crew the day was more classic: a maintenance EVA for the atmospheric experiment, adjusting the planning for the next week, repairs in the RAM…

For this one, I would like to thank a lot our Crew Engineer Matheo, who made a great job with the MegaAres antenna, tinkering with what we had in the RAM: it was out of service since the beginning of our mission, and we will be able to put it on the field by tomorrow! Thank you again Matheo (take a look at him and me, striking a pose in front of the “brand new” antenna!).

All the crew is now looking forward to tomorrow, our first “Martian rest day”! We can’t wait!

Summary Title: Back to (Martian) reality

Author’s name: Cerise Cuny

Mission Status: Nominal

Sol Activity Summary: In the morning we did an EVA to change the batteries of the atmospheric experiments. Nicolas and Valentine tried to make contact with Toulouse, in France (simulating a different Mars settlement) but it failed, they are going to try again in a few days.

For lunch, we cooked soup with some of the cabbage of our last harvest. It warmed up the crew members which was quite necessary as the day was very cold. Just after lunch, Shannon retrained us about EVAs and the philosophy of the sim. We were very grateful to have feedback: it will help us live the Martian experience better. We then finished the Mars puzzle together, which was quite a nice cohesion activity.

In the afternoon, we worked on our EVA requests to make them precise. Some of us went through human factors experiments. Two of the crew members used the RAM and its tools to do some repair work.

Anomalies in work: None.

Weather: Mostly sunny.

Crew Physical Status: Good.

EVA: One EVA in the morning, went well. We are doing 2 EVA Requests for tomorrow.

Reports to be filed: Sol Summary, 2 EVA Requests, EVA Report, Operations Report, Journalist Report, HSO Report, Astronomy Report.

Oil Added? No.

ATV Fuel Used: 0 gallons

# Hours the ATVs were Used: 0

Notes on ATVs: Nothing to report

HabCar used and why, where? Yes, local

CrewCar used and why, where? Yes. Atila took it to drive to SLC to pick me up but lost control and went off the road close to I-70 on Highway 24. He was shaken and sore afterwards but the car was checked and appears to have no damage.

Luna used and why, where? No.

Campus wide inspection, if action taken, what and why? I have not completed my inspection fully but noted no damage/changes to the Robotic Observatory exterior, instrumentation nearby or the solar panels. Signs on the road and at the entrance have no damage/changes.

General notes and comments: I arrived back at MDRS on Wednesday night and Atila will be leaving MDRS on Saturday morning.

Summary of general operations:

Summary of internet: The original Hab internet service will be deactivated on March 1, 2022. Today the new system was to be installed, but the installer cancelled. I will be installing a Starlink system that hopefully can be used while we are waiting for HughesNet to get its act together.

Summary of suits and radios: Nothing to report

Summary of Hab operations: The toilet holding tank was cleaned for the built up waste that was making the tank fill twice as fast as when nominal. We were unable to see how successful we were, but will track the crew’s use to see if we cleared it completely. We will repeat this process in 4 weeks.

Summary of Outpost operations: Nothing to report

Summary of GreenHab operations: I inspected the GreenHab the morning after I arrived. From what few details I was getting from reports and photos, it was clear something was wrong. Nothing was thriving and plants were dying and underproducting. A more detailed inspection showed an unchecked infestation of white fly and contamination of soil by eggs and larva. I determined a collapse was near, salvage wasn’t possible, and we shut the building down. The crew removed all crops and consolidated the soil, and I will be finishing the removal of plant debris over the next few days. Heat is off and supplemental lighting turned off. This failure was the result of not one, but many small things. I was offsite and hadn’t been paying enough attention to the reports to realize that the crew was not reporting vital information about the condition of the plants. Our supplemental operations report had become truncated in a way that didn’t allow clear reporting on GreenHab issues by Atila. The GreenHab Officers and Atila didn’t have the knowledge and experience to recognize what was happening and I was offsite. Although we are requiring a general skill set for GreenHab Officer’s beginning next season, we do not have any requirements at the moment and it is one of two positions that are generally not filled by qualified people. Finally, but maybe not of much importance, I requested that the crew install a shade cloth weeks ago, and that was never gone. Dying plants were reported as drying plants. This is, however, why we do what we do—to learn from what mistakes we make. We probably won’t be able to produce anymore crops this season, because we need to sterilize the soil before we can replant and that requires heat, sunlight and time.

Summary of ScienceDome operations: Nothing to report

Summary of RAM operations: Nothing to report

Summary of any observatory issues: Robotic observatory is down. A part to repair it is due here Saturday.

Summary of health and safety issues: Nothing to report
