Terraforming
The Umbrian Republic has established outposts in a number of different systems where no naturally habitable biosphere is present, including several whose worlds represent near misses for sustaining Umbrian life. These worlds are tantalizing targets for futurists, dreamers, and would-be terraformers.
Space propulsion
A vast number of different propulsion types have been fitted to Umbrian spacecraft since it first began launching objects into space, including chemical rockets, electronic thrusters, solar sails, beam-powered devices, and nuclear pulse engines. While all were capable of propelling objects through space, the most effective proved to be electric engines, such as ion or plasma thrusters. These are commonly referred to ion engines or ion thrusters, no matter their actual subtype.
