Summary of Hab operations: The crew spent the morning trying out their project hardware (drones and Starlink mini) before starting simulation at noon. The crew split into two EVA teams and went to Marble Ridge as a MDRS tradition. Afterwards, we performed a 100cameras module with HSO Koi before dinner.

Water Use

Time of measurements: 2040
1) Per formula: 45.75 gallons
2) Smart Home Dashboard: Unable to calculate with main generator down

Water (static tank, remaining gallons): 461.78 gallons

Static tank pipe heater (on or off): No

Static tank heater (on or off): No

Toilet tank emptied (no or yes): No

Summary of internet: Used to complete reports, learn languages, share team photos via Google drive, streaming shows

Summary of suits and radios: Two EVAs were performed today, splitting the teams into two halves in order to complete the marble ritual.

· EVA 1: Suits 6, 8, 10 and Radios 1, 3, 4

· EVA 2: Suits 7, 9 and Radios 1, 2

Summary of GreenHab operations: Watered all plants and harvested some basil to go with olive oil for dipping with bread.

WATER USE: 10.8 gallons

Heater (On or Off): On

Supplemental light (hours of operation): 1900-2200

Harvest (name, weight in grams): Basil, Parsely, and Chives… all amounted to a handful but unable to weigh due to inoperable scale.

Summary of ScienceDome operations: Set up engineering project hardware (EVA Connectivity Kit and 3D Scanning Kit) and tested Starlink Mini outside at the observatory.

· EVA Connectivity Kit: Starlink took approximately 5 minutes to connect, and immediately uninstalled a software update. Crew Artist, Crew Journalist, Crew Engineer, and HSO were all able to connect successfully. Several speed tests were performed, with a maximum download of 186 Mbps and upload of 19.0 Mbps. 16% of the battery pack was consumed over 20 minutes.

Dual split (Heat or AC, On or Off): Off

Summary of RAM operations: (Tools used, work done)

· Leaking Sink: needle nose pliers, adjustable wrench, and plumber’s tape taken – all returned to the RAM. A little troubleshooting revealed that the stopper was clogged and needed to be removed, cleaned, and reinstalled. Plumber’s tape was added to the stopper’s side port to prevent leaking. Previously the stopper was wrapped externally with tape, but that was removed after the plumber’s tape solved the problem.

· Loose Staircase Mat: adjustable wrench, 3/8” deep socket, 2 nuts, and 2 washers were taken – nuts and washers were consumed, all other tools returned. The topmost staircase’s mats are loose, and it was discovered that no washer and nut was installed on the underside of the mat in two locations. A washer and nut was added, tightened, and now the stair provides less of a tripping hazard.

· Zip Ties: Only several open grommets were noted, mainly ones underneath other tarps. However, afternoon gusts liberated several zip ties that need replacing. I will make a routine of replacing the zip ties every morning before afternoon gusts arrive. In short, no zip ties were used today.

Summary of any observatory issues: None

Summary of health and safety issues: None

Non-nominal systems: Main Generator, Spacesuit Charger #7, Perseverance Rover

Notes on non-nominal systems:

1. (Unresolved from yesterday) Oil leak on the main generator, which requires us to use the backup generator at night. This is being worked solely by Mission Support and does not require crew engineering.

2. (Unresolved from yesterday) It was noted that Suit #7 wasn’t charging, but further diagnosis from the Commander has isolated the issue to the #7 charger. Troubleshooting this will take place over the next day.

3. The Perseverance Rover has two minor issues: the parking brake does not fully engage and have much effect, and the ignition block rotates fully if you turn the key too hard by accident.

General notes on rovers: None

Summary of Hab operations: Two EVAs were performed today, the first to collect rock samples and the second to take desiccated soil samples. A 100cameras module on camera features was performed with the crew after breakfast. A major repair of the tunnels’ zip ties was also performed (details under RAM notes).

Water Use

Time of measurements (collect data for the same time window): 1930
1) Per formula (see notes): 29.41
2) Smart Home Dashboard (see notes): 25.25

Water (static tank, remaining gallons): 432.37

Static tank heater: Off

Toilet tank emptied: No

Summary of internet: Used to complete reports, learn languages, share team photos via Google drive, researching projects

Summary of suits and radios:

· EVA 1: Suits 2, 3 and Radios 2, 3

· EVA 2: Suits 7, 8, 9 and Radios 1, 3, 5

Summary of GreenHab operations: Plants were watered, some basil leaves were harvested for meals. Since the fan doesn’t reliably work due to the main generator being inoperable, the temperature increased quicker than normal and needed to be regulated via opening the GreenHab door.

WATER USE: 10.4 gallons

Heater (On or Off): On

Supplemental light: 1900 – 2200

Harvest (name, weight in grams): Handful of basil leaves (unable to weigh due to faulty scale)

Summary of ScienceDome operations: Began the 3D scanning project with the rock samples recovered on EVA #3. A Rubik’s cube was first used as a simple model to scan, which didn’t work initially. I performed some more research using some downloaded manuals and videos to better understand the software before starting with a first rock sample. The results were much better, yielding a 3D model of a sample after about 2 hours of work. The model was lacking color, but more work will be done to add color to the texture and reduce scanning time. A power study for the EVA Connectivity kit was also performed.

Dual split (Heat or AC, On or Off): Off

Summary of RAM operations: (Tools used, work done) put notes here

· Zip Ties: Snips and 44 zip ties were taken from the hab, all to repair the tunnels’ tarps. I’m uncertain if the large amount of zip ties that needed to be replaced was because of the last several days of no engineering support between crew 314 and 315, or if certain zip ties were intentionally not replaced. Approximately half of those zip ties were applied on grommets that didn’t have any nearby zip ties on the ground.

· GreenHab Scale: I hoped that the scale needed a simple AAA battery swap, but it proved to be more complicated. The screen does not turn on even with fresh batteries from the exercise bike. I need to investigate the interior components for any obvious issues.

· Spacesuit #1 Repair: After personally attempting to wear two-piece suit #1, Commander Laude discovered that the neck ring had been installed upside down. I used a screwdriver and pliers to uninstall, flip, and reinstall the neck ring for future use.

· Other hardware used: measuring tape for water usage measurements, and an extension cord and 5 specimen jars were taken from the RAM for ScienceDome projects to be returned at end of mission.

Summary of any observatory issues: None

Summary of health and safety issues: None

Questions, concerns and requests to Mission Support:

· Is there a way to download the data from the Home Assistant program? That will allow the GreenHab specialist and myself to more accurately record the average temperature and water usage, respectively. Attempting to download the data on the graph view takes us to a new Safari page that cannot be viewed.

· Is there any issue with using a scale in the ScienceDome to weigh harvested plants in the GreenHab? Or must they remain in their respective areas?

Non-nominal systems: Charger #7, Space Suit #1, #3, Perseverance Rover, Curiosity Rover

Notes on non-nominal systems:

1. (Unresolved from yesterday) It was noted that Suit #7 wasn’t charging, but further diagnosis from the Commander has isolated the issue to the #7 charger. Troubleshooting this will take place over the next day.

2. Space Suit #3’s neck ring cord broke and needs to be reinstalled. Its cord was cannibalized from Suit #1 to support an immediate EVA and will be fixed this evening. Suit #3’s oxygen cord was also cross-threaded upon install and is stuck. Some quick work with some elbow grease and adjustable pliers will fix it this evening.

3. (Unresolved from yesterday) The Perseverance Rover has two minor issues: the parking brake does not fully engage and have much effect, and the ignition block rotates fully if you turn the key too hard by accident.

4. The Curiosity Rover has a lagging battery indicator. On EVAs, its battery life percentage will drop by only a few points and register much later on the following EVA. This is believed to be fixed by watering the battery with DI water, an action for Mission Support.

Summary of GreenHab operations: Watered all crops, cultivated fungal project, and opened door when temperatures exceeded 94 F.

WATER USE: 11.0 gallons

Heater: Yes

Supplemental light: 0000 to 0900 and then 1900 to 2200 (light was on all night due to script needing to be rebooted)

Harvest (name, weight in grams): tomatoes (66g), chives (8g), parsley (5g)

Summary of ScienceDome operations: It was a late night last night to map the second rock sample with the 3D scanner, but it proved to be successful and very informative. This morning a third sample was scanned in about an hour… half the time of previous samples! The Crew Journalist also began her desiccated soil experiment in the ScienceDome this afternoon. The fan that cools the power converter was turned on to level 3.

Dual split (Heat or AC, On or Off): Off

Summary of RAM operations:

· Space Suit Repairs: As mentioned above, neck ring cords were swapped on suits 3 and 1 to facilitate EVA 6.

· Crew Artist’s Crazy Straw: Gagnon requested the ability to drink from his water bottle on EVAs without taking off his helmet. I fashioned a clean rubber hose from the science lab into a drinking apparatus that tapes to the suit helmet. With a little bit of adjustment, it worked well on EVA 6. Once the mission is over, it will be cleaned and returned to the dome.

· Tunnel Zip Ties: Only one zip tie was missing after yesterday’s evening gusts! A more thorough check will be performed in the AM. One zip tie was taken for install in next daylight.

· GreenHab Scale: a scale was repurposed from the ScienceDome to measure GreenHab harvests. Still troubleshooting the original scale to see if it can be fixed in the RAM.

· Other Tools Uses: Additional jars (2) were taken for rock specimens. A tool bag, carabiner, and rope tape measurer were taken for the Crew Journalist’s project, and a Rock Hammer was taken for rock specimens. All will be kept in the hab for EVA use until mission duration.

Summary of any observatory issues: None

Summary of health and safety issues: None

Questions, concerns and requests to Mission Support: Great work on fixing the main generator Mission Support! This will lower noise levels and allow us to monitor station health via Home Assistant more consistently.

Summary of RAM operations:

· Tunnel Zip Tie Repair: Only one zip tie was needed to be replaced on the tunnels after

· Suit Repair: Suit #1’s repair of the neck cable ring was extremely simple once Scott Davis from Mission Support informed me of the extra space suit pieces. I had tried to fabricate my own cable ring with cable from the RAM and crimping it with no success.

· GreenHab Scale: For reasons unknown, fully disassembling the Greenhab scale and reassembling it worked! I guess that there was some dirt between the circuit board and the buttons that could have prevented contact. The ScienceDome scale was returned to the ScienceDome after the GreenHab scale was returned to the GreenHab.

· 3D Scanning Shroud: I was able to craft a rudimentary shroud for en situ 3D scanning for my project, but I want to confirm that all components can be sent out on EVA on Sol 6 or 7. Please see questions to Mission Support below.

Summary of any observatory issues: None

Summary of health and safety issues: None

Questions, concerns and requests to Mission Support: Two requests

· We would like to see if we can get the closeout checklist for the season early. We want to start reviewing the actions needed to close up MDRS for the summer.

· For my 3D scanning project, I plan to scan rock samples on EVA and need a way to create a large area of shade for the activity. I was able to create a shroud with the two sawhorses, clamps, and the fire blanket from the RAM. As soon as I tested the concept, I returned the blanket to its location. However, I do want to see if I can take these items with me on future EVAs? I would only take the RAM’s blanket, would ensure other crew members aren’t in the RAM when there is no blanket, and would call out the blanket’s use on EVA. If this is approved, let me know what is necessary to properly communicate its use.

Summary of RAM operations: (Tools used, work done)

A total of 24 zip ties were used to secure the tarps to the metal structure between each module. The ends of the zip ties were cut using a wire cutter. Additionally, duct tape was used to patch a large hole in the tarp near the Science Dome.

The crew engineer, Antoine, used a drill to attach the dust collector brackets to the stakes during the EVA (tools used: drill, mete r& 6 zip ties).

Summary of any observatory issues: Nothing as no observations done yet

Summary of health and safety issues : Our engineer was still a bit blurry this morning, but he was still able to participate in the daily tasks. We will take an eye on his health issue for the days to come, and keep you updated. The other members were feeling fine.
First Aid Kits : All medical supplies have been filled.

Questions, concerns and requests to Mission Support :

Request to Mission Support :

EXPERIMENT : The team has applied for support to collect a parcel containing important samples for our journalist’s experiment.

HSO :

As mentioned in the email’s response (HSO pre-mission checklist) : We have two issues with the walkie-talkies from SciDome: the one working on channel 10 is dead and doesn’t work on any other charging base. Unfortunately, the charging base for the SciDome is also no longer working.

As mentioned in the email’s response (HSO pre-mission checklist) : there’s no new alcaline battery left in the drawer (precicely : Alcaline Battery 9V 522-6LF22 -6AM6). We have received a response from Mission Support that batteries will be coming in the beginning of next week.

Summary of any observatory issues: /

Summary of health and safety issues : Our crew engineer is steadily improving each day. As for other issues, we encountered minor incidents, such as cuts, for which we applied band-aids to Batoul and Arnaud. Additionally, a minor issue occurred in the Science Dome when the autoclave overheated, causing a power failure and triggering the gas alarms due to the release of a large amount of steam. We had to request assistance from Mission Support to resolve the situation.
About the inventory : 4 band aids have been used today, and 1 antiseptic towelettes.
