Today was an exciting experience when the 5i crew was interrupted for a simulated off-nominal emergency. Quick tack and uncompromising teamwork was required for both the ARG-5i crew and MCC. After the hours of excitement from the simulated emergency they enjoyed the rest of Moonfall and the Ghostbusters for movies the evening. MS Cecil completed the Crew Patch for the Autograph wall.
The Emergency Mission
The crew executed an Emergency EVA to repair a simulated H2S (Hydrogen Sulfide) Gas leak located in the Science Habitat. Working together in the afternoon they had to split up int an EVA team and an IVA (inside the habitat) team to coordinate instructions and repairs through multiple platforms. MS DeJan and MS Gonzalez completed the Emergency EVA repair, while MS Cecil and CO Turner maintained the IVA. CO Turner monitored the ATACK and ECHO and MS Cecil relayed coms.
MS DeJan and MS Gonzalez briefed the crew on comms check procedures and timing milestones throughout the chronologically sensitive EVA. Both suits were easier to ingress than last EVA event, shaving 4 total minutes. This reflects positively on MS DeJan’s tactic of drying suits after utilization. The crew quickly located the valve mechanism and MS Gonzalez coordinated the timing milestones with IVA while MS DeJan single handedly closed the valve and patched the leak. The handheld camcorder failed (memory full), but luckily MS Gonzalez carried a secondary recording system (GoPro) and successfully captured the repairs. Total time habitat egress to repair was just under 6 minutes. The task was simple and to the point, perfect for MS Gonzalez’s performance metric.
Co Turner monitored the mission and MS Cecil manned the Wave Relay system and MPU5 radio. Comms checks went smoothly, and EVA crew departed at 1330 with MCC instructions for repair of leak. IVA maintained consistent comms with EVA crew and relayed communication with MCC. EVA crew successfully located and repaired the leak. CO Turner donned the gas mask gear, flipped the vent ‘on’ in the Science lab for two-minutes, and returned to the core hab. MS Cecil monitored command and Persistent Systems while all crew members were executing their tasks. Team work proved imperative and everyone executed their tasks smoothly.
The Crew was successful at locating, repairing, and completing the simulated emergency EVA, bringing all systems nominal in the habitat.
Hamama
Everyone was excited to see the first bud burst through the brown paper. The system seems to be working well and the crew is on track to harvest food in the next couple of days.
Martian Soil
MS Cecil’s project progresses as planned. Her soil has began to settle and the Ph levels are equalizing. After some good data she finished off her day by watching movies with the crew and eating... popcorn??
Measuring EVA Performance
MS Gonzalez was ecstatic because of the success of the the off-nominal today. MS DeJan and MS Gonzalez both produced excellent metrics and the performance is well documented. The off-nominal system set out by Dr. Miller and the MCC members forced the crew to work together and also highlighted some other performance considerations not contemplated when he initially designed the study. Additionally, MS Gonzalez is now tracking asleep and awake times, which have been particularly diverse among the crew and even more interesting when compared to psychomotor vigilance test results.
Mutually Sustained Systems for Space Flight
Results were proof this morning that little if any plant based O2 is being produced in the container. The final CO2 reading was off scale high (4800+PPM). The plants were in total darkness for 10 hrs. So, time to head in a different direction. The plants will be sealed tonight after venting to ambient CO2 levels (410PPM), and the Grow Lights left on. Starting readings of CO2 will be measured tonight, end readings in the morning at 0800hrs. The lit period will be 11hrs. The only observable result is when the CO2 readings are low, 1 PPM is produced in less than one second and maintains the level of 1 PPM in 1-3 seconds until the tank contains greater than 3000 PPM, then the production level drops to 1 PPM every 5-6 seconds. The seedlings appear to be doing well, and the Mars soil plant seem slightly weakened but still holding on.

Green Study
CO Turner enjoys seeing the growth of microgreens. Nothing to report as of yet in the Martian Regolith. Even under infused conditions, nothing has occurred, which she finds interesting. CO Turner is excited to see growth on day two and looking forward to the outcome of this project.
