Crew 275 Sol Summary Report 19Feb2023

Sol: 7

Summary Title: Winter is over, time for a Spring cleanup!

Author’s name: Jeremy Rabineau, Commander.

Mission Status: Nominal.

Sol Activity Summary:

Yesterday evening, we took some time to celebrate the end of this successful first week at the MDRS. This was a great bonding time with games, music, and even some dancing! In the morning, we all took part in a longer sport session and then enjoyed nice pancakes together. We could tell by the crewmembers’ faces that everyone was happy to take some time away from the stress of the operations and to talk about other things. We also took this opportunity to fully clean and tidy up the station. Only our GreenHab Officer could not take the opportunity to change his schedule too much: no Sundays for the plants! Our batteries are now fully charged to start Week 2 with a lot of energy (and we will need it!).

Look Ahead Plan:

Tomorrow, we would like to start the first photogrammetry EVA at North Ridge. The aim will be to use drones to take pictures of the area and to postprocess them using photogrammetry. Then we will have a 3D map that will allow us to: 1) Contextualize the collection of rock samples; 2) Evaluate the added value of such maps to ease the exploration during the next EVA in this same area. On our way to North Ridge, we also plan to do some final adjustments, change the batteries, and retrieve the data of the atmospheric instruments located close to Marble Ritual.
After interacting with the researchers responsible of the MegaAres instrument, we came up with a plan for the maintenance of the MegaAres antenna. It will require a day with two EVAs next week: a short EVA for the retrieval of the antenna in the morning, and a longer one to put it back in place and perform some tests in the afternoon.

Anomalies in work: None.

Weather: Sunny, low -9°C/15°F, high 4°C/39°F.

Crew Physical Status: Optimal.

EVA: None.

Questions, concerns, and requests to Mission Support:
• Greenhab radio: the volume of the channel 1 radio was very low. I conducted a check on this radio with the user manual, and the volume is still low. We decided to change radios between channel 1 and 22 in the Greenhab. Indeed, important communication among the Crew are transmitted on channel 1, and transmissions with Mission Support are always managed in the Hab and summarized on channel 1.
• Concerning the toilet, I have listed this system as non-nominal since the beginning of the mission because it was reported as so before. However, we have not experienced and bad smell since the beginning of the mission. Do you still need to change the toilet tank?
• We did not experience any failure for the propane generator, is it still considered as non-nominal?

Summary of RAM operations: The RAM was not used because of the freezing temperatures. There is no more whistling sound. There is no more leak.

Summary of any observatory issues: The robotic observatory was open until around 12:30.

Summary of health and safety issues:

At 5:27 am, the Commander woke up and detected that there was a power outage, and a very low temperature on the Upper and Lower Decks (56°F / 13°C on the Upper Deck, much less on the Lower Deck). He immediately notified Mission Support who promptly reacted. He also notified the Crewmembers to wear hot clothes and to stay in their rooms, where the temperature was warmer.

At 5:32 am, power came back in the main Hab, and propane detectors warmed up.

At 5:34 am, the Lower Deck propane detector’s alarm rang, announcing a “possible gas leak”. The Commander, the HSO and the Crew Engineer reacted to the emergency. The Commander notified Mission Support. The HSO and Crew Engineer went to the RAM to get the two gas detectors.

Back in the Hab, crewmembers began an inspection of the Lower Deck with the gas detectors.

At 5:39 am, the alarm stopped. Crew members continued to monitor the situation, and seek for a potential gas leak. As the temperature was very low, Mission Support instructed to Crew to switch on the Lower Deck heater. This took about 20 minutes, because the heater did not switch on before (there was no gas going out from the pipe, even though the valve was open).

We finally managed to switch on the heater, and Crew members rested before starting their daily activities at 6:45. A propane gas detector was left ON in the Lower Deck to monitor the situation. It ran out of battery around 2 hours later.

The yellow gas detector showed weird values: when the red gas detector was beeping, the yellow one still showed the same value of LEL (0 to 2%)
The heater was left on during most of the day, and the temperature was back to normal (72°F) at 10:57 am in the Upper Deck.

Questions, concerns, and requests to Mission Support:
• The oven is working now. Same for the heater on the lower deck, after 20 minutes of trying to switch it on, it switched on
• Greenhab Radio on channel 1: the sound of the radio is very low, even though the volume is at MAX, it is hard to hear the person speaking, what can we do?
• Both gas detectors ran out of battery, each one work with 3 AAA batteries, and we have no more AAA batteries.

• Science Dome: As yesterday, 1 leak coming from the junction between the ground and the wall under the window. A small amount of water leaked from the outside and flowed into the Science Dome. The puddle was about 1 cm high, 5 cm wide, and 3 meters long at 3:00 pm, and is located close to an electric socket. As yesterday, 1 leak coming from the junction between the ground and the wall near the door. The puddle was about 0.5 cm high, 3 cm wide, and 70 cm long at 3:00 pm. This second puddle fully dried during the afternoon. A third leak appeared at the junction between the ground and the wall under the window, but in the right side of the window. At 5:00 pm, the puddle was about 0.5 cm high, 4 cm wide and 1.5 meters long, and it is located close to an electric socket.
• Science Dome: as per protocol of an experiment, the Crew Engineer placed an environmental sensor in the Science Dome, including a temperature sensor. A recording of the temperature was performed during the night, and it shows that the temperature decreased during the whole night. Therefore, we assume that the heater did not turn on properly. I can send you the graph of the temperature between 11:55 pm and 6:55 am if you need it.
• GreenHab: supplemental light did not switch on yesterday at 10:00 pm. The Crew Botanist went in the GreenHab to set up the timer at the right time (it was 10 to 15 minutes late).

• Static tank pipe heater: On
• Static tank heater: On
• Toilet tank emptied: Yes

Summary of internet: Hughes Net was used during the day before the opening of COMMS for email purposes, and Starlink is used during COMMS. Environmental sensors were connected to Outpost 2g local network. We use the latter to have a communication between the sensors and a computer. No internet data should be used through this process, as we only use it locally.

Summary of suits and radios: Spacesuits were not used today, as there was no EVA. Spacesuit n°6 was repaired yesterday and is not considered as non-nominal anymore.

Summary of GreenHab operations: The Crew botanist set up the aquaponics system, harvested and watered the crops. He also seeded carrots.
• WATER USE: 14.25 gallons
• Heater: On
• Supplemental light: From 10 pm to 2 am
• Harvest: 166 g of carrots (without leaves, and 364 g with leaves) – 2 g of thyme

Summary of ScienceDome operations: The Commander and crew Scientist tested some experimental protocols, and observations were performed with regards to the leaks. An environmental sensor was placed on the table.
• Dual split: Heat / From 10 pm to 7 am

Summary of RAM operations: Crew Engineer and crew Astronomer trained to build the weather station which will be set up during an EVA later on. Countermeasures were taken with regard to the leak. RAM operations were suspended at 11 am because of the very cold conditions in the RAM.

Summary of any observatory issues: Nothing to report.

Summary of health and safety issues: A crew member slightly hurt their finger during routine operations.

Questions, concerns, and requests to Mission Support:
• Does the astronomer have his own wifi network to plan the observations? If so, what are the login and password? If not, which wifi network should he use to plan observations?
• Would it be possible to have an extended use of the Starlink network? We have one experiment which will require a 24/7 access to a good internet connection. It will not use much data (we can monitor it with you on the first days, and reduce it if needed). Would it be possible to have a 24/7 access to Starlink? Again, we will not use it all the time, we will use it during random moments of the day.
• If the previous request is not possible, is it possible to have a supplemental access to Starlink between 2 pm and 5 pm?
