Astro class

The Astro Class were a series of crewed spaceprobes developed by the World Space Commission for Solar System exploration missions.

In "Matter of Life and Death" Lee Russell is mentioned as an astronaut deceased in the Astro 7 mission to Jupiter, in 1994 (10 July 1995, according with The Moonbase Alpha Technical Notebook), using an Astro-class ship.

Later is known that the Astro-class craft's route was influenced by a gravity-like force and Russell was shipwrecked on Terra Nova, evolving into a sort of anti-matter life form.
