Can we design a spacecraft to reach Proxima Centauri, the closest star to our Sun?
Why undertake such a journey, for the pleasure of conquest or for necessity?
According to some, humanity will be multi-planetary or it will not be.
The simplest option would be to establish an autonomous colony on Mars: a planet close to us, but whose possibility of terraforming remains unknown.
Another option would be to colonize the nearest exoplanet. Of course, the journey would be longer, but if it turns out that this rocky exoplanet, Proxima b, located in the habitable zone, also has an atmosphere, oxygen and water, it could be the birthplace of the first independent human colony.
