This propulsion system is based on the principle that direct energy transfer from fission fragments (FF) to the propulsive gas is by far more efficient than using basic heat exchanges. Many potentially interesting fissionable fuel elements have been surveyed, trying to identify the best choice according to the following criteria: (1) large fission cross section; (2) high fission probability; (3) acceptably long lifetime; (4) reasonable production procedure. On this basis, at least two isotopes appeared to be of interest for the application, namely in order of merit Americium 242 and Plutonium 239.

In the near future, both terrestrial and space-based telescopes will allow analyzing the spectrum of planets’ light to ascertain the presence of other chemical elements, such as oxygen. However, with present technologies, it is not possible to detect the presence of a moon around a planet orbiting its star in the habitable zone, nor can one detect the presence of a magnetic field around it. Only an exploratory probe will be able to gather this information, which will be able to confirm that the planet is suitable for human colonization.

It was only Giordano Bruno—an Italian Dominican friar, philosopher, mathematician and astronomer—that put forward the radical view that space is infinite, that the fixed stars are similar to the Sun and are likewise accompanied by planets. His cosmological theories went beyond the Copernican model in proposing that the universe contained an infinite number of inhabited worlds populated by other intelligent beings. In the 18th century, the possibility of stars similar to the sun and accompanied by planets was mentioned by Isaac Newton in the “General Scholium” that concludes his Principia.
