To populate another solar system, the crew would have to live there and live there for several generations to procreate. For the trip with 98 people must be started, write Frederic Marin of the University of Strasbourg and Camille Beluffi of the research company CASC4DE in the "Journal of the British Interplanetary Society."
Also a disaster was included
For the selection of the crew Therefore, to clarify some issues first: the number of women and men, age and life expectancy, fecundity rates and maximum capacity of the spacecraft. In addition, strict rules for life on board are necessary. In addition, the number of births must be fixed each year. In their computer simulation, the authors allowed incest and allowed reproduction only at the age of 32 to 40 years. In their calculations, Marin and Beluffi even calculated a catastrophe after 2500 years, which cost 30 percent of the crew's life. However, there are still uncertainties – such as how cosmic rays affect the crew.
Proxima Centauri b orbits around the star Proxima Centauri, which lies about 4.2 light-years from Earth. A light year is the distance traveled by light in one year and equals 9.5 trillion kilometers. The discovery was announced by researchers in August 2016. But before this mission is clarified, that the planet is habitable, emphasize the authors.
