Today we will begin our look at the spaceships we might use for colonizing interstellar space in the future. In order to cover the vast distances between even the nearest stars in our galaxy within the boundaries of known physics, we need vessels able to voyage at high speeds for very long periods of time while carrying everything they need to colonize another solar system, a concept typically known as a space ark or generation ship. We will explore the challenges and options for such a vessel, as well as some alternative approaches to the problem.
