８０－１　Starship Solar-System（SSS）
○Since the life expectancy of the sun is 5 billion years, the human race needs to be moved to any other stellar systems.
○30,000 years to go to our nearest neighbouring star, Alpha Centauri (distance: 4light years) by the fastest spacecraft today.
○If you think the energy and safety between the long-term move, it is necessary to utilize the forces of nature.

○The solar system is orbiting through the Milky Way galaxy in 240km/s.
○If you have a solar system on the spacecraft, long-term energy and safety can be ensured.


Solar System [1]

○Movie：The helical model - our solar system is a vortex[2]

○Proposal of Martyn J. Fogg(1989) [3] [4]
・Stars like the sun exist about 300 within a distance of 100 light-years. This plan assumes that to finish the replacement work of the sun and other stars in about 10 million years. 
・First, put a ring of superconductor around the sun, and supplement the 10% of the energy of the total output of the sun. Then generate a toroidal magnetic field by flowing a strong current, and rectify the flow of charged particles spewing from the sun in one direction.
・With this propulsion system, the movement speed of the sun after 700,000 years will be 1km / s, and you can change the scope of the course 1.9 degrees with respect to the rotation axis. After 2.7 million years each of those will be 5km / s, 9.5 degrees, and after 10.7 million years 20km / s, 33.7 degrees.
・Next, select the course that slip through the side of the star of the target. And adjust the inrush course to put the Earth in orbit of the other stellar.

８０－２　Starship construction plan：Proposal to Breakthough Starshot [6]
○Still, we can not experiment with the solar system, so we will experiment with the nearest star (Alpha Centauri).
The plan is as follows.

○Purpose of this plan：To remodel Alpha Centauri closest to the solar system (4 light years) into a star ship that all humans can live in.

○Method: In this plan, 100 gram mini spaceships equipped with GAI and nano machine will be accelerated to 5% of the speed of light with a solar sail and will be sent to the planet of Alpha Centauri in 100 years.
※ For the basic concept see RenéHeller and Michael Hippke's proposal. [7] [8] [9]
※ The energy source of the propulsion system is the sun and Alpha Centauri.
※ The size of the sail is 100,000 square meters (about 14 soccer fields).
※The sail is made of graphene which is a very thin and light carbon film and covered with a cover with high reflectance so that it can endure the harsh conditions of the deep space and the heat of the star of the destination. (10 years for development)
※If it is higher than this speed, the craft will pass Alpha Centauri.

○ Structure of Nanocraft：
Camera, nuclear battery, propulsion system, navigation, communication equipment, nano machine 


※NASA

☆ Crew
• Crews are two GAIs (Neutralink of male and female brain tissue: Adam and Eve)
・Two GAIs are backed up and restored to each other.

○Root

※The root of Starship [9]

☆Schedule
10 years later Launch of No. 1 Nanocraft 
20 years later Completion of the laser propulsion system of Star shot 
25 years later Star shot firing 
45 years later We will get information from the star shot (resource, landable land, landing method).
50 years later Launch of No.2 nanocraft (supply ship) (2 new GAIs)
100 Years later Arrive at Alpha Centauri, collaboration of 2 nanocrafts and receive supply material (landing and terraform material etc)
150 Years later Arrive at earth type planet of Alpha Centauri and start of terafoam (mineral collection and processing, construction of solar panels etc)
160 years later Start of building a Starship 
☆2,000~3,000 years later 　the completion of the Starship- Starship construction plan 
☆40,000 years later Humanity will arrive at the starship (Alpha Centauri)
☆10 million years later Reaching of a Starship to the other star. [4]
