Crew 310 Operations Report 08-02-2025

SOL: 6

Name of person filing report: Helena Arias

Non-nominal systems:

Robotic Observatory

Hab secondary structure

Spacesuit 7 ventilation

Notes on non-nominal systems: Maintenance of the observatory planned for June. There are air leaks in the upper deck of the Hab. Some scratches were covered with duct tape and bubble wrap. Other scratches will be covered during this evening using the same method. Opportunity’s tire is already filled with air and under observation. The ventilator on spacesuit 7 stopped working instantaneously during the first EVA but started working again after shaking the backpack.

Summary of any observatory issues:

Robotic observatory: Not working. Maintenance planned for June.

Summary of health and safety issues: none

Questions, concerns and requests to Mission Support: The engineer requests guidance to check and fix the ventilation of Spacesuit 7. The crew has also experienced some issues with the LilyGoes. After arriving to the final location in the first EVA of the day, LilyGo 7’s location kept updating in the same position with no change. All devices were reset during the activity of the EVA. The four LilyGoes were checked once the crew arrived to the main Hab, as no change was noticed in the iMAC. LilyGo 7 was reset again with no success. This same LilyGo was taken in the second EVA by error, but it started showing it’s location as LilyGo 10, instead of 7. Guidance is also requested in order to solve this issue.

Name of person filing report: David Steinhour
Reason for Report: Routine
Non-Nominal Systems:
-UV lamp has arrived for the water filter, and it is awaiting installation.
-Small cracks in the wall of the Hab in the loft area are allowing cold air intrusion.
-Generator piston rings are slowly going bad, and the generator is at more than 4x its recommended service life before overhaul.
-Opportunity tire is leaking.
-Crew car driver side ball joint needs replacement
-Power system battery
-Tear in tarps where the tunnels meet outside the science dome."

Hours: 209.5
Beginning Charge: 100 %

Notes on Rovers: Opportunity’s right rear tire was low on 2/8. No leak was easily found. It was refilled and checked throughout the day of 2/8. with no major leak identified"

Cars: "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).
Hab Car used and why, where: To Hanksville for supplies.
