Slogan [1]

• Exponential expanding with solar power and steel forming ability on M-type asteroid in Deep Space.

Informally speaking, it's just a project on automatically duplicate the solar furnace for steel smelting in deep space.

Overall

through the system below:

1. With adaptive optics reflector
2. Towards asteroid in M-type
3. Under the process of Solar focus pit melting
4. And the process of Rolling/Forming/3D Printing
5. To duplicate the adaptive optics reflector at exponential scale
6. Through space robotics and AI system

achieve the goal of limited the supplement from the earth, bootstrap from the Initial Base Package to exponentially scale up the industry in deep space.

Prospective goals

1. Double the volume of production for each year, get 1 million tonnes per year in 10 to 20 years
2. It is equivalent to kilos of cabins a year of expansion
3. While closing and achieved the scale,

1.3AU

A near-Earth object (NEO) is any small Solar System body whose orbit can bring it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU).[2] If a NEO's orbit crosses the Earth's and the object is larger than 140 meters (460 ft) across, it is considered a potentially hazardous object (PHO).[3] Most known PHOs and NEOs are asteroids, but a small fraction are comets.[1]

Production

一次性制造大规模太空城市

十年指数增长扩展到一千组聚光阵后在理想情况下可以集中1GW的能量（大约三峡的1/21），粗略的估算可以在三到五年内将约一千米尺度的目标小行星从头到尾熔融一遍，通过控制熔池能量密度可以蒸发铁蒸汽调整小行星自转，控制离心能量同时集中在自转轴加热有可能可以将整颗小行星转化成直径上千米的空心滚筒，这是个现成的巨大规模太空城市基础

同样规模的聚光阵也可以推动C类碳质小行星变轨

Why we need industry in deep space

• the anchor for the next leap
• payloads for LEO/other orbit structures

the EDS

Exponential Deep Space

Why asteroid #3

• Natural M-type, recycling of billion-years scrap metal
  • easy, 70Fe30Ni
  • (million tones enable industrial space city
  • (further to C/S-type with vehicle and equipment #27
• challenge
  • rotation of asteroids
  • material property and limits
  • robotics in the space (at the exponential scale

How we do

• 5 Solar furnace

  • 4 magnetic shield and torquer

• 6 Forming and shaping

• 7 Robotics

What will this impact

• enable heavy structure in large-scale (like in LEO etc
• space industrial base and city (for multi-purpose
• the gate of the interplanetary era for human being
  • industrial/inhabit base
  • vehicle for interplanetary transfer
  • extend the industry to C/S-type, and further
  • large scale science research/industry
• ROI

How to do

It's a long journey.

• The digital world is easy to be exponential, while the atoms don't.
• To exponentialize the physical world, what we need are model and resource.
• It's a data drive company at first, evaluate the models in physics by stages.
• Close loop the mass and the resource.

How to make the Apollo-scale project done while roughly not by the government?

• KSP+Kaggle for distributed open source contribution of the problem solve
• grow up the new generation
• bootstrap the simulated project detail at Phase I, kick-start the physical evaluation

Why start as simulation

• for a large project at this scale, the plan should be systematic
  • evaluate the situation from all directions
• make everybody stand on the same page
• can be extended to games/other related

Evaluate experiments

• 15 parts of 6 sections in the first stages
• 6 (?) of them should be physically evaluated in the first (6) years

Engineering

• demonstration and research on the ground/water tank
• space evaluation of sub-systems
• (dedicated detector

Time and roughly budget frame

• GDoc sheet
• products
  • KC Communication unit
  • MPT
  • Kaggle mode
  • Cabin

Team and community

• crews
• more
