Hohmann

Mathematical models, simulations, and early Gemini flight experiences determined that the optimal altitude difference between the two spacecraft was fifteen miles, and that the ideal transfer angle—the angular distance the Gemini spacecraft needed to traverse during its rise to the higher orbit of the Agena—was 130 degrees rather than the 180 degrees or halfway around the globe called for by the so-called Hohmann transfer.

As Hohmann so eloquently said in a recent interview, When our country was small, we had a participatory democracy -- people in town halls hashing out issues.

Although the three days he and his wife spent manually calculating (no computers back then!) a Hohmann transfer orbit to verify the veracity of a single sentence in that book is probably carrying this a little too far.

Seventy years on, the furry critters are now as populous in some areas of Germany as in the major urban centers of North America -- a whopping one per hectare (2.5 acres), Hohmann said ...

We've sent space probes to Jupiter; they take five and a half years to get there if we send them on a straight Hohmann transfer orbit, but we can get there quite a bit faster using some fancy orbital mechanics.
