"And so Discovery drove on toward Saturn, as often as not pulsating with the cool music of the
harpsichord, the frozen thoughts of a brain that had been dust for twice a hundred years." - From 2001 a Space Odyssey by Arthur C Clarke.
Here are some images of my scratch built Discovery Dragonfly from the novel 2001 a space odyssey by Arthur C Clarke.
The Dragonfly configuration very closely matches the description of the Discovery as it was described in the novel.
The wing like appendages are radiators which would dissipate any excess heat produced by the nuclear engine.
Stanley Kubrick eventually rejected this design because well... they looked like wings. Opting instead for the more bone like configuration that we all know and love.
