Saturn Probe

Saturn Probe was a series of short stories and prose features published weekly in TV Century 21 across some of 1969, specifically from 8 February to 5 July.

The series documented the progression of a manned mission to Saturn and, eventually, the establishment of a colony named Shindigville. Set in TV21's shared universe of the 2060s, Saturn Probe and was by extension a part of the expanded Doctor Who universe.

Crossovers with the DWU
Despite the series taking the headline article in one of TV21's cover stories and another of its instalments crossing over with fellow 2060s-based series Fireball XL5 through the mention of Space City and the World Space Patrol, only one Saturn Probe ultimately contained elements from the Doctor Who universe. This was a short story titled Oil Drill Shipped to Crater!, which mentioned Unity City, the capital of the World Government first introduced in The Daleks comic strip.
