Aphrodite Prime

One of 20 smaller aerostats, Aphrodite Prime hovers  54 kilometers above Aphrodite Terra. It is a center for  Venusian tourism; fully a quarter of this aerostat is a  resort for wealthy offworld visitors. Aphrodite Prime  is also the primary research station for the design and  creation of life forms adapted to live in the Venusian  clouds. This aerostat has a population of 300,000 and  features closed-environment test aviaries populated  with clouds of air plankton and schools of recently  designed flying squid and balloon fish.
