Operations Report – October 07th

MDRS Operations Report 5-7-OCT-2021

Name of person filing report: Shannon Rupert and Crew Engineer/XO David Laude

Reason for Report: Routine

Non-nominal systems:

Action taken for non-nominal systems:

Generator: Nothing to report

ScienceDome Dual Split: Off

Solar— Nominal, providing all power

Solar— SOC % Last 24 hours:

Average 60.1

Minimum 14

Maximum 100

Note on solar: We are recovering from a day and a half of rain and clouds.

Diesel Reading – Empty, tank to be removed soon

Propane Reading, station tank – 76 %

Propane Reading, director tank— 71 %

Propane Reading, intern tank— 72 %

Propane Reading, generator— 80 %

Ethanol Free Gasoline – 1 gallons

Water (loft tank): 35 gallons. From the dimensions I calculated this to have a 60 gallon full to top of main tank capacity. The numbers written on one end are in close enough agreement with that. So, from that our water usage has been 25-30 gal/day on average. The water meter says 32 gal/day.

Water Meter: 152,581 units

Water (static tank) – 300 gallons

Static to Loft Pump used –yes

Water in GreenHab – 40%

Water in ScienceDome: 0 gallons

Water (Outpost tank) – 175 gallons

Hab toilet tank emptied: yes

Perseverance rover used:


Beginning charge: 100

Ending charge:

Currently charging: yes

Sojourner rover used: yes


Beginning charge: 100

Ending charge: 100

Currently charging: yes

Spirit rover used: yes

Hours: 140.8

Beginning charge: 100

Ending charge: 99

Currently charging: yes

Opportunity rover used:


Beginning charge: 100

Ending charge:

Currently charging: yes

Curiosity rover used: yes

Hours: 148.0

Beginning charge: 100

Ending charge: 98

Currently charging: yes

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

ATV’s Used: (Honda, 350.1, 350.2, 350.3): All four were started and checked.

Reason for use: routine maintenance

Oil Added? Yes, to 350.1

ATV Fuel Used: 4 Gals

# Hours the ATVs were Used today: 0.25

Notes on ATVs: Both of the Honda’s rear tires are flat. I need to take them off and see if they are repairable. The oil is dirty on all four. They need to have a full tuneup and oil change. 350.2 runs well but is too dangerous to use. 350.3 needed the bolts on the battery tightened.

HabCar used and why, where? Yes, to town to pick up the trailer from storage and bring it back to campus

CrewCar used and why, where? Yes, to town to fill up with gas to turn it over to the crew. Also used to go get COVID test in Grand Junction.

Luna used and why, where? Yes, to town

General notes and comments: People were adding trash to the trailer where it was parked at storage so I went and picked it up. I had some trouble with the hitch but some people in town helped me with it. Lugs on the tires were also tightened, however the rear of the two axles has been bent in the past and needs replaced.

Summary of internet: All accounts are nominal.

Summary of suits and radios: Suits good, but sometimes charger connector to EVA suit needs jiggling to charge. Looks like same problem and same type connectors I saw here in 2009. The newer barrel connector style might work better. 5 radio batteries have been identified as not suitable for further use and will be removed from the hab so no other crew will have to fuss with them. 3 radios have been identified as faulty and labeled. They are on the second shelf down on the radio table in lower hab. There are just enough batteries remaining for all the working radios. Likely a few more batteries may not be up to par as I did not test all. The tested good batteries will run a radio in transmit on high power for ~25 minutes continuously. Intermittently my guess is ~30 minutes.

Campus wide inspection, if action taken, what and why?

Summary of general operations: No significant worries.

Summary of Hab operations: Replaced loft tank and portable kitchen water jug filters. Toilet leak is ~ 2 gal/day of potable (I assume) water .

Summary of Outpost operations: Transfer of the construction trash from the work party has begun. Director Trailer blackwater emptied.

Summary of GreenHab operations: All good except purple watering can was damaged. Still works.

Summary of ScienceDome operations: DNA sequencing on regolith samples on going.

Summary of RAM operations: No action.

Summary of any observatory issues: Robotic observatory is down.

Summary of health and safety issues: Everything good.

Questions, concerns, supplies needed and requests: I need to put two weird little metal pieces on the trailer to attach the new VIN number. They look like thumb tacks but instead of a skinny metal pin they have a thick, blunt metal pins divided into fourths. Can anyone help me with this? How do these things work? (Shannon) If trailer is on campus I can look after sim. I don’t know how from your description. Since it’s for a VIN maybe it’s some permanent attachment that requires force and tools to place into holes (Dave)
