Operations Report Oct 08th – 10th

MDRS Operations Report 8-10-OCT-2021

Name of person filing report: Shannon Rupert

Reason for Report: Routine

Non-nominal systems: Complete Failure of Power System occurred on Saturday the 9th at 6 am.

Action taken for non-nominal systems: On Saturday, we awoke to a brownout, which is something that isn’t supposed to happen with our system and has never happened before. After about ten minutes of this, we lost power. SOC was 16%. One of the power controllers had tripped its breaker, but I didn’t know when, so nothing to do but resent it and wait until sunrise. Once the sun was up, all three charge controllers returned to nominal operations. I attempted to use the generator before sunrise but my first attempt failed. I changed the generator control to autostart, knowing the generator was programmed for autostart. It started well, but struggled and lagged, finally backfiring and quitting. The autostart was cancelled so will need to be reprogrammed on the generator before it can be used again. Error read undervolt L1-2. I attempted a second manual start but the generator turned itself off in a minute. So we waited for the sun to confirm the solar system was working. It was but we still weren’t getting power. My second attempt to restart the inverters worked and the system has been functional since. In the meantime, I restarted the generator with the breaker off and it ran well, then I flipped the breaker with the SOC at 30% and the generator did not struggle. I turned the generator off so I could clean and check it before putting it in service again. For the next few days I will once again run on solar only until this is done then I will test the system again.

Generator: Run three times on Oct 7 during a power failure.

ScienceDome Dual Split: Off

Solar— Except for during the complete power failture on Saturday it has run nominally, although struggling to keep up with power demand on rainy and cloudy days

Notes on rovers: Additions to the frame to protect the spacesuits have remained intact and functional.

ATV’s Used: (Honda, 350.1, 350.2, 350.3): Honda

Reason for use: removed two rear tires for repair

Oil Added? No

ATV Fuel Used: 0 gallons

# Hours the ATVs were Used today: 0

Notes on ATVs: Nothing to report

HabCar used and why, where? No

CrewCar used and why, where? Yes, to deliver crew to Grand Junctoin

Luna used and why, where? Yes, to town

General notes and comments: CrewCar needs repair before next crew arrives. Running well, but needs work on the undercarriage. The HabCar’s windshield has been scratched so much that it is difficult to see through it when the window isn’t cleaned. The windshield washer tank is broken so people have just been clearing and scratching it without any fluids.

Summary of internet: All accounts are nominal.

Summary of suits and radios: Nothing to report

Campus wide inspection, if action taken, what and why? Diesel tank removed, remaining spill containment system needs to be removed.

Summary of general operations: Diesel tank has been removed from campus. Old blackwater tank has been transferred to the trailer for disposal.

Summary of Hab operations: Nothing to report.

Summary of Outpost operations: Propane detector in director’s trailer malfunctioned after power failure and was removed. During removal, the fuse to the water pump failed. This is an amazingly short story for what was a really long and interesting learning experience. The thermostats in both trailers were replaced and the heating unit in the intern trailer was reinstalled after being cleaned and checked.

Summary of GreenHab operations: Nothing to report

Summary of ScienceDome operations: Nothing to report

Summary of RAM operations: Ladder was used and was reattached to the tunnel

Summary of any observatory issues: Robotic observatory is down.

Summary of health and safety issues: Nothing to report

Questions, concerns, supplies needed and requests: Nothing at this time.
