Here, Nano-Genetics is used in the context of biological engineering for future space missions where laser propulsion or particle accelerators enable space agencies to launch long-distance space flights to explore far away exoplanets.
It is clear that biological existence as known, forcing engineers to launch rockets with kilograms of payload to overcome gravity fields, cannot be accelerated to speed ranges close to 1% and above of light speed. This means to fly faster than 30000 km/s or 108 Mio. km/h. One should remember that this is almost 10000 times faster than well-known values for speed of sound on Earth, which serves as reference for high speed air planes.
In order to construct organic life on microscopic scales, science has to follow the creative steps of bonsai or pomeranian breeder which managed to downsize trees and wolves to surprisingly small existences. Nowadays, Biologists achieve unbelievable results with regards to agriculture, nevertheless we are yet far away from nano-genetical lives, which could be injected into coin like space vessels.
From our current point of knowledge, milestones for nano-genetics could be:
1. Status quo of existing downsizing breeding methodologies, e.g. those used by successful bonsai and pomeranian breeders and other well-known biological experts in this field.
2. Comparison of breeding technologies and nano-spaceship requirements, including temperature and information coding for long-distance exoplanetarian space missions using particle and/or laser accelerators.
3. Integration of organic and anorganic substanced into coin sized space vessels and start of high speed launch experiments, to achieve speed ranges of 1% light speed and more.
