One concern in How long could the Mars helicopter Ingenuity keep up with the Perseverance rover if it wanted to? is that the helicopter must cycle its battery every night to stay warm, and that could severely limit its lifetime.
Question: Could Ingenuity stay warmer at night by landing on (or near) Perseverance's RTG?
If landing on top of the RTG would be too dangerous or toasty, could it land on the surface under the RTG and bask in its radiant heat and stay significantly warmer than being completely exposed to the cold martian sky? (How cold is the Martian sky at night? Or the day for that matter?)
