World ships are hypothetical, large, self-contained spacecraft for crewed interstellar travel, taking centuries to reach other stars. Due to their crewed nature, size, and long trip times, the feasibility of world ships faces an additional set of challenges compared to interstellar probes. Despite their emergence in the 1980s, most of these topics remain unexplored. This article revisits some of the key feasibility issues of world ships. First, definitions of world ships from the literature are…

There's No Place Like Home (in Our Own Solar System): Searching for ET Near White Dwarfs
The preponderance of white dwarfs in the Milky Way were formed from the remnants of stars of the same or somewhat higher mass as the Sun, i.e., from G-stars. We know that life can exist around
Android Noahs and embryo Arks: ectogenesis in global catastrophe survival and space colonization
It is concluded that an advanced civilization using an integrated, embryonic approach to recolonize Earth after global catastrophes and to colonize exoplanets could eventually colonize distant parts of its home galaxy and potentially the wider universe.


Artificial Intelligence for Interstellar Travel
The role of artificial intelligence for interstellar travel is explored by compiling use cases, exploring capabilities, and proposing typologies, system and mission architectures, covering those proposed in the literature but also presenting novel ones.
Beyond astronaut ’ s capabilities : a critical review
Prolonged human presence in space has been studied extensively only in Earth orbiting space stations. Manned missions beyond Earth’s orbit, require addressing further challenges: e.g. distances
Computing the minimal crew for a multi-generational space travel towards Proxima Centauri b.
It is shown in this paper that it is possible to create and maintain a healthy population virtually indefinitely and a minimum crew of 98 people is necessary to ensure a 100% success rate for a 6300-year space travel towards the closest telluric exoplanet known so far.
HERITAGE: a Monte Carlo code to evaluate the viability of interstellar travels using a multi-generational crew
It is demonstrated that if initial social engineering constraints are indeed needed to maintain an healthy crew alive for centuries-long journeys, it is necessary to reevaluate those principles after each generation to compensate for unbalanced births and deaths, weighted by the inbreeding coefficient and a need for maximizing genetic diversity.
Numerical constraints on the size of generation ships from total energy expenditure on board, annual food production and space farming techniques
In the first papers of our series on interstellar generation ships we have demonstrated that the numerical code HERITAGE is able to calculate the success rate of multi-generational space missions.
Roundtrip Interstellar Travel Using Laser-Pushed Lightsails
This paper discusses the use of solar system-based lasers to push large lightsail spacecraft over interstellar distances. The laser power system uses a 1000-km-diam. lightweight Fresnel zone lens

Exploring Potential Environmental Benefits of Asteroid Mining
Asteroid mining has been proposed as an approach to complement Earth-based supplies of rare earth metals and supplying resources in space, such as water. Existing research on asteroid mining has
