Capabilities for Long-Duration Landers on Mercury
Mercury surface assets will be exposed to extreme thermal swings over a Mercury day (-180 C to +430 C). Dayside operations, in particular, are challenging from a thermal control and power perspective. Consequently, the latest planetary decadal survey process included a Mercury lander concept that only operated during the night. Recent technology advancements in high and low temperature systems may enable new science over the entire Mercury day.
