This site focuses on high performance sustainability technologies, especially related to closed-loop life support, especially those that can be reused for sustainability purposes on Earth. Some coverage is also given to the use of remote sensing for sustainability purposes.

Technologies are organized into the following categories:

  • Air (air recycling, sensing, clean-up)
  • Astroculture (space crop chambers, agriculture)
  • Comprehensive (systems supplying multiple human needs)
  • Energy (generation, storage, distribution, monitoring)
  • Waste Recycling (solid waste recycling)
  • Water (wastewater treatment, drought mitigation)


  • Accelerators/Incubators
  • Funding
  • Competitions


  • Blogging about space technologies that have potential for sustainability purposes on Earth
  • Concept and product development
  • Microgrants
