Dragonfly, the probe–aircraft which NASA has decided will soon be sent on its way to Titan, the giant moon of Saturn, is in my thoughts today. In particular, I want to know where the plutonium–238 for its thermoelectric power source will come from. Otherwise, I mostly discuss my travel plans, both for returning to the USA and for this autumn ; Deutsches Museum, one of the greatest science and technology museums in the world ; and the curious railway station at Eisenstein, where the border between Germany and the Czech Republic is halfway along the platform.
