To live an exoplanet, the crew must live several times (generations) in a spaceship and multiply there. For this reason, 98 people should go on a trip, writes Frederic Marin of the University of Strasbourg and Camille Beluff of the research firm CASC4DE in the journal Journal of the British Interplanetary Society
The choice of l & # 39; crew should address several issues: number, age and life expectancy of women and men, fertility rates and spatial capabilities. In addition, strict rules would be necessary for life in the spaceship, the number of births should be determined each year. Using computer simulations, scientists rejected incest and "allowed" to only spread 32-40 crew members so that offspring were genetically healthy.
In the study, the researchers even included a possible catastrophic event of 2,500 years. the life of the crew members. However, uncertainties remain, such as the impact of cosmic radiation on the crew.
Proxima Centauri B bypbades the Proxima Centauri star, which distances the Earth in about 4.2 light-years. Light is the distance that light reaches during the year, it corresponds to 9.5 trillion.
However, before this mission, it remains to be determined if the planet can reside entirely, emphasize the authors.
