Questions, concerns and requests to Mission Support:

A request was submitted to Mission Support to assist the crew in closing the main entrance door, which had suddenly slammed open due to strong winds and became stuck. Thanks to Mission Support’s prompt intervention, the issue was successfully resolved.

Can we have a new pack of 11 inch cable ties ? The package was emptied during the tunnel check.

Since some of the canned goods and food supplies (such as eggs, coffee, etc.) were already partially used upon our arrival, would it be possible to receive a resupply?

Reason for Report: Routine
Non-Nominal Systems: Crew car. Power system battery, inverters, generator. Robotic observatory. HAB outer shell. Spirit.

Power system:
Solar: The battery bank does not hold charge when sun is down and low on the horizon. Inverter Slave 1 and 2 went offline and do not restart, which limits us to 5kW when on solar.
Main generator has been monitored for oil leaks; minor leaks observed, Moreover, generator is consuming oil because of worn piston rings. Adding oil every day is necessary. Generator is limited to 8kW, see previous reports for details. Engine governor is being stuck in open position during startups and needs to be replaced, new part ordered.
Main generator:
1) Oil, oil filter and air filter changed on 04/11/2025. Hours: 9260.2
2) Current hours – 9274.4.2

Notes on Rovers: Spirit is not charging. Perseverance’s parking brake needs to be adjusted.

Cars:
Hab Car used and why, where: To Hanksville for supplies.
Crew Car used and why, where: By crew from Grand Junction.
General notes and comments: Crew car driver’s side front ball joint is bad. Low oil pressure is most likely caused by a bad sensor (it does not change due to RPM or temperature like it should).

Name of person filing report: David Steinhour
Reason for Report: Routine
Non-Nominal Systems: Crew car. Power system battery, inverters, generator. Robotic observatory. HAB outer shell. Spirit.

Power system: "Solar: The battery bank does not hold charge when sun is down and low on the horizon. Inverter Slave 1 and 2 went offline and do not restart, which limits us to 4kW when on solar.
Main generator has been monitored for oil leaks; minor leaks observed, Moreover, the generator is consuming oil because of worn piston rings. Adding oil every day is necessary. Generator is limited to 8kW, see previous reports for details. Engine governor has been replaced, and the threads of one of the governor bolts was stripped and repaired with a heli-coil insert. Oil is still leaking from the flange that is held down by this fastener – the gasket could need replacing.
Main generator:
1) Oil, oil filter and air filter changed on 04/11/2025. Hours: 9260.2
2) Current hours – 9364.1"

Propane Readings: "Station Tank: 70%
Director Tank: 62%
Intern Tank: 84%
Generator Tank: 42%"

Water: "Hab Static Tank – 550 gallons
GreenHab – 200 gallons
Outpost tank – 225 gallons"

Rovers: "Sojourner rover used: Yes
Hours: 212.9
Beginning Charge: 100 %
Ending Charge: 100 %
Currently Charging: No
Notes on Rovers: Spirit is not charging. Perseverance’s parking brake needs to be adjusted."

Cars: "Hab Car used and why, where: To Hanksville for supplies.
Crew Car used and why, where: By crew from Grand Junction.
General notes and comments: Crew car driver’s side front ball joint is bad. Low oil pressure is most likely caused by a bad sensor (it does not change due to RPM or temperature like it should)."
