Building a spaceship that can travel to Alpha Centauri, or father, will require prefabrication of large space vessels, in orbit, around planet Earth, like building a spaceship the size of the International Space Station, as it orbits the planet, and then test the systems out in orbit, and take the prefabricated space vessel out into outer space. The spaceship vessel will have to be prefabricated in a containment area, that has a large platform, in which spacewalks can be performed, to join together the different capsules or components, including with in-space welding, and there will have to be a living center on the large platform, that the prefabrication crew can live in, while the large spaceships or spacecraft are prefabricated, in space.
