NSS Space Settlement Nexus

We look forward to people living and working in thriving communities spread throughout the solar system, making use of the vast resources of space for the betterment of humanity. As space resources are discovered and developed more and more people will find it advantageous to live and work in space, culminating in a sustainable ecosystem of settlements in both free space and on various celestial bodies. A foundational principle of our vision is that space must be open to all nations and all peoples, with no artificial limits on who can go or how they choose to live.

The National Space Society presents the case for space solar power, the future of clean, safe, limitless energy for everyone. Space solar power will harness the power of the sun in orbit and beam energy where it is most needed on Earth, eventually replacing fossil fuels and allowing our planet to once again become the pristine home we deserve.
