Summary Title: A day of rest
Author’s name: Andrew Wheeler
Mission Status: Nominal
Sol Activity Summary: Today was scheduled to be a day of rest and personal time. However, it didn’t quite turn out that way. One crew member awoke to a severe migraine and another to a stomach upset and their wellbeing was our main concern. Nevertheless, washing and cleaning was able to be done and a very short EVA to return the solar logger it’s recording point was carried out in the early morning. The Mars jigsaw puzzle was completed and signed and an issue with the lower level gas heater was remedied.
Look Ahead Plan: We will return to robot rover testing on the ground around the hab in the morning and an EVA to the stream draining from Tharsis Montes in search of concretions in the afternoon. If the weather holds, the solar observatory will also be operated.
Anomalies in work: Lower level gas heater anomaly – see operations report.
Weather: Clear crisp morning at -5 Celsius rising to low teens during the day. High cirrus cloud later in the day. No precipitation. Humidity continuously dropping from near 60% to below 40%. The wind was faint to gentle during the day.
Crew Physical Status: Severe migraine headache as well as stomach upset – see HSO report.
EVA: EVA 12 with Andrew and Clare to return the solar logger to it’s recording position and an external inspection of the hab tunnels.
Reports to be filed: Sol Summary, Commander’s Report, Greenhab Report, Operations Report (including an HSO report), EVA report, EVA Request(s). There is no Astronomer report for today.
Support Requested: Nothing to request.

Non-nominal systems: Hab downstairs wall heater
Notes on non-nominal systems:
At around 18:30pm, the crew upstairs heard a strange sound coming from downstairs (sounded like rushing water). We went downstairs to investigate and smelled gas. We saw that the wall-mounted heater (to the right of the engineering airlock) that the left side of the heating grill was operating normally (glowing red), but the right was not glowing and there was a visible flame behind. Commander Andrew immediately turned the thermostat to the off position as I radioed mission support to advise on the situation. The flame then went out and the rushing sound stopped. We opened the engineering airlock door to vent the gas from the room. No alarms were triggered. The gas heater thermostat is now set to “off” and confirm the pilot light is still burning.

Narrative:
Today was the crew’s rest day, although the plants still needed tending. I visited the GreenHab in the morning around 9:15 and stayed for a while to check in on the heater. It was on when I entered at 73 F and turned off several minutes later when the temperature read 76 F. Heating system nominal!!! I started the plants with a nice morning misting. Unfortunately, cukes #1 and #3 were looking a little wilty. I suspect they may have gotten some direct hot air from the heater – they were placed on the metal shelves overnight. I made a note not to leave them there when the heater was on. They were placed down on the floor for the day in the shade of the mesh shade cloth (later moved to the wooden pallet with the tomatoes). I also pruned some dead leaves from tomato #4 and inspected the fruits on tomato #9 – they look nice and red and a little squishy to the touch. I think tomorrow might be harvest day for them. I gave the plants their first watering of the day with 3 gallons. Soundtrack of the day was Jackson Browne. Today, I joined the crew in completing the Mars puzzle on our rest day. I set regular alarms to check in hourly on the plants, recording the temperature and giving a mist on each visit. By 1pm, the temperature had reached 100 F, although I did not observe the anomalous heater-turning-on issues the crew observed the previous sol. Looks like there may have been an initial hiccup in the system, but is now working ok. I gave the plants another watering of 3 gallons in the afternoon, and did some rotations of the tomatoes, and moving other plants out of the sun. Alex caught a bee inside the hab, which was also relocated to the GreenHab (I have yet to see it). For the past few sols, I have been eying off the carrot box – only a few carrot heads appear to have germinated, and there is a lot of free space in the box. Luckily, I did bring a packet of carrot seeds with me. I dug two shallow trenches on the left side of the box, away from the existing carrots, and added some seeds – following the instructions to apply 4 seeds per inch during initial planting, and to spread them out later after germination (expected to be 8-12 days). I will make sure to keep the carrot box nice and moist. In the afternoon, temperatures began to cool, and the heater was turning on periodically keeping the temperature above 75 F.

EVA Report – January 28th
EVA # 12
Author: Clare Fletcher
Purpose of EVA: Deploy solar logger before sun gets too high. Solar logger had stopped working on 27-01-24 and was retrieved on EVA #10.
Start time: 0800
End time: 0815
Narrative: Prior to the beginning of EVA #12, Alex reported having a migraine and was unable to join this EVA. Given I (Clare) was awake, I volunteered to help on this EVA to deploy the solar logger. Andrew and I made good time getting ready and left on time. We deployed the solar logger outside the Science Dome and turned it on. After this, we inspected the tunnels quickly as we intend to hold a practice emergency depressurization EVA during the week (EVA request yet to come for that one).

Summary Title: A day of rest
Author’s name: Andrew Wheeler
Summary: Today was a down day for the 291 crew after spending a hectic and tiring 6 days climbing up the ridges and through the gullies surrounding the MDRS. Personal time to wash and clean clothes and a well deserved (though very short) shower was the order of the day. However it didn’t turn out that way. One crew member reported in with a severe migraine and another with a stomach upset. As for the rest of us, it was a quiet day mindful of our colleagues. Though the day dawned crisp (-5C) and clear, high cirrus cloud ruined any chance for astronomer Rob obtaining clear observations of the sun after missing out for most of last week. With the assistance of Clare during an early morning EVA, I returned the solar logger to its position outside the science dome, having recharged the battery to full. It should be good for a few more days. Whilst out on this EVA, we inspected the outside of the hab tunnels for micrometeorite damage and general state of repair.
In quiet mode, the mobile crew members discovered the Mars jigsaw puzzle and about completing the 999 piecer (it was a 1000 piece puzzle but the top left corner piece has disappeared!) to keep us occupied. In a herculean effort, the task was completed before dark and the back signed in accordance with the tradition. During dinner, an issue with the lower level gas heater was dealt with and reported to mission control.
As crew recover overnight, Sol 8 should see us refreshed for further exploration of the MDRS area and testing of robot equipment.

Sol: 6
Summary Title: The search continues
Author’s name: Andrew Wheeler
Mission Status: Nominal
Sol Activity Summary: A repeat of yesterday, Sol 6 dawned bright, clear and cold; perfect weather for EVAs. It also allowed the solar observatory to be utilised for the first time. The morning EVA saw a return to Kissing Camel Ridge in search of access to Hab ridge and the locations of fossil beds, concretions and petrified wood. The return to the parked rovers during this EVA was via a different route that pushed the EVA into the reserve time. A lesson learned. The afternoon EVA chartered new territory into Candor Chasma (via Galileo Road) in the search for fossil beds and spectral targets. A location for fossil beds was identified as well as more green and red mudstone lithologies. Interestingly, purple mudstone beds and salt coated rocks were located and will be potential targets for spectral analysis on later EVAs. Pizza and fresh salad greeted all for the evening meal and very welcome it was.
Look Ahead Plan: A day of rest and consolidation. However, in expectation of clear weather again, the solar observatory will continue to have the idiosyncrasies worked through to allow clear observations of the solar surface. With no EVAs scheduled, the crew will be able to catch up on interpretations and conclusions as well as personal time.
Anomalies in work: An incursion by curious visitors in to the campus In the afternoon.
Weather: Clear crisp morning at -6 Celcius rising to low teens during the day. No precipitation. Humidity continuously dropping from near 60% to below 40%. The wind was faint to gentle during the day.
Crew Physical Status: nominal
EVA: EVA 10 with Clare and Scott to Kissing Camel Ridge en route to Hab Ridge in search of fossil beds, concretions and petrified wood.
EVA 11 to Candor Chasma via Galileo Road reconnoitering for spectral targets, fossil beds and concretions.

Crew Scientist: Clare Fletcher
Crew Engineer and Green Hab Officer: Scott Dorrington
Crew Astronomer and Medical support: Rob Hunt
Crew Journalist: Alex Tobal
Crew Projects:
Title: Geological mapping and sensor deploy
Investigators: Andrew Wheeler, Clare Fletcher, Steve Hobbs and Scott Dorrington,
with full-crew participation.
Objectives:The mission objectives are to revisit geologically interesting locations, deploy sensors to characterize mineralogy, locate them in the topography for navigation purposes and characterize the sites for preservation.
Current Status: Two sensors were meant to be deployed and were scheduled for EVA 3. One, a solar logger previously deployed during the FMARS15 mission in July/August 2023, was successfully positioned outside the science dome in view of the panoramic window. The second sensor, an electronic Stevenson Screen with multiple environmental sensors, was unable to be initiated due to circuitry burnout in the secondary battery pack and an, so far untraced, electrical fault in the primary battery pack, has not been deployed at this time.
A robotic rover has been deployed on five occassions to test wheel traction at various slope angles at locations near to and remote from the hab. On two occasions a portable spectrometer was deployed to collect data from various lithologies. There are expected to be more EVAs in support of this project.
The geological boundaries that influence the geomorphology and topography surrounding the MDRS have been visited on six occassions in search of unmapped outcrops of the target rocks and minerals – gypsum, carbonate concretions, fossil beds and horizons containing petrified wood. Previously mapped locations have been revisited and plotted into a GIS for reference by follow on crews. Constraints imposed by the cold weather on the rovers have prevented expeditions to the more remote locations. There are more EVAs planned to support this project.
As part of the geological EVAs, map reading and compass bearings are taken to prominent features that can be viewed from multiple directions. The ability to accurately triangulate position to prominent features is designed to build confidence in non compass navigation as a failsafe/backup to GPS/satellite navigation. More EVAs in support of this project are planned.
EVAs: 11 EVAs have been carried out. EVAs 1 and 2 were training exercises for the whole crew. Three EVAs have been conducted in and around the hab. Three EVAs have been conducted to the south and southeast and three EVAs have been conducted to the north and northeast.
Title: Monitoring Solar activity
Author: Rob Hunt
Objectives: The MDRS solar observatory will be utilized for the daily monitoring of
solar activity.
Current Status: Total cloud cover during the day has prevented the operation of the solar observatory until Sol 6 and this day was spent working through the idiosyncracies.
EVAs: None.
Title: Investigations for establishment of MARS-Oz in Australia.
Author: Alexander Tobal
Objectives: This project is focused on collecting observations of how analogue
astronauts operate under simulated conditions and how the MDRS hab setout
influences operations and if improvements can be incorporated into the MARS-Oz
design.
Current Status: Observations of the activities of the analogue astronauts as they carry out their activities inside and outside the habhave been collated and summarised in a living document and is ongoing.
EVAs: None
Journalist Report – January 27th
Mining and Dining
Milk rationing is now in effect. In practice, this meant experimentation with some pretty egregious alternatives – i.e., Scott and Clare eating strawberry frosted flakes with ‘Orange Delight’ cordial… and Rob using diluted buttermilk pancake mix in lieu of actual milk.
We also experimented with dehydrated potato slices in the hopes of creating a super-chip (crisp). There’s potential there. Potential that wasn’t realised today, but potential. By the end of the day we also got a couple of pizzas up and running, which rounded off things in a special way.
You’ve probably noticed that I talk a lot about food. I suppose this is meaningful in a way that might not initially be apparent – i.e., that food will be incredibly important to crew morale over long-term expeditions to Mars, just as it has been to us. There’s something to be said for the joy of recreating a staple meal (or creating a new one) in a restrictive environment where many other luxuries might be unavailable, and especially in growing your own. It brings people together, provides an outlet for creativity and experimentation, and serves as a daily (for some, hourly) motivator.
We conducted two EVAs today, both of which involved a drive out to mineral sites for reconnaissance purposes. Scott also (successfully) used both opportunities to experiment with a theodolite app to help measure angles between geographical features, as well as conventional analogue measurements.
EVA 1 travelled south to Kissing Camels Ridge (another name that never gets old) and found some great samples (as well as ‘weird things in the dakota’… Clare’s words, no further explanation given). From there the team also got a great view of Skyline Ridge.
EVA 2 travelled further north-east to Candor Chasma and found some good samples of their own, as well as some other curiosities: a fossil bed (fossilised worm burrows and more ‘Devil’s Toenails’), lots of cow dung, plus a watering hole (possibly two?) with surrounding hoof-prints. They also found unexpected salt deposits.
Back at the station, Rob got to spend six hours in the station’s observatory studying the sun.
We also had a UFO incursion – i.e., a car drove directly through the station and then encountered our EVA team on the road. Luckily they came in peace.
Highlights of the day: Pizza, EVA 2 returning early, surprise salt, accidentally fossil discovery.
Lowlights of the day: Pre-diabetic improvised breakfasts, EVA 1 returning late and losing a marker pen to Mars, dodgy Greenhab thermometers, UFO incursions are escalating.
– Alexander Tobal, Crew 291.
