Terraformer missile

From Tardis Wiki, the free Doctor Who reference

Terraformer missiles were used by Dollar Intergalactic for terraforming in the 25th century.

Terraformer missiles initiated the terraforming process and served as foundations for Terra-Sphere towers. One such missile accidentally hit the spacecraft of Rann-Korr, a Hyperion hibernating on Isen VI. As a result, Rann-Korr received access to the terraforming process. (COMIC: Terrorformer)
