- 8. Next Target: OrbitYour lifetime: thousands of people living in orbitA few centuries: most of humanity in orbit. Next millenium: generation ships to the starswww.engineerkaushal.webnode.com
- 9. Orbital Space SettlementWho? Ordinary people. What? Artificial ecosystems inside gigantic rotating, pressurized spacecraft. Where? In orbit; near Earth at first. How? With great difficulty.Why? To grow. When? Decades. How much will it cost?If you have to ask, you can't afford it.www.engineerkaushal.webnode.com
- 10. WhoToday: highly trained astronauts.$20-40 million tourist trip to MirSurvivor in Space Tomorrow: everyone who wants to go.100 - 10,000,000 people per colonyUltimately, thousands or even millions of coloniesSounds unrealistic?A hundred years ago nobody had ever flown in an airplane.Today ~ 500 million person/flights per year.www.engineerkaushal.webnode.com
- 11. WhatA space settlement is a home in orbit, not just a place to work. Live on the inside of air-tight, kilometer scale, rotating spacecraft.www.engineerkaushal.webnode.com
- 12. WhereIn orbit, not on a planet or moon. Moon (1/6g) and Mars (3/8g) gravity too low. Children will not have the bones and muscles needed to visit Earth.Orbital colonies rotate for 1g.Continuous solar energy.Large-scale construction easier.Much closer: hours not days or months.www.engineerkaushal.webnode.com

- 17. How much will it cost?If you have to ask, you can’t afford it. How much did Silicon Valley cost? Orbital space settlements will be far more expensive:all materials importedtransportation difficultbuild all life support hostile environmentnew techniques must be developedwww.engineerkaushal.webnode.com

- 60. Conclusion The colonization of the solar system could be the next great adventure for humanity. There is nothing but rock and radiation in space, no living things, no people. The solar system is waiting to be brought to life by humanity's touch. And computer science can help.www.engineerkaushal.webnode.com
