Conclusion: The high‑temperature and high‑dust environment stressed the sealing and thermal design; minor firmware updates to the dust‑sensor filter algorithm eliminated a transient over‑temperature event. Overall, performance exceeded the 90‑day mission requirement for autonomous science campaigns.
