  • Independent private group plans Alpha Centauri mission
  • Focuses on achieving the lowest possible launch cost
  • Faces monumental engineering and interstellar challenges

A private collective of scientists and engineers is working on an ambitious space exploration initiative aimed at sending a spacecraft to the Alpha Centauri star system, our closest stellar neighbor, with the absolute lowest possible budget and operational costs.

The primary challenge of interstellar travel lies in the immense distance, requiring advanced propulsion concepts capable of reaching a significant fraction of the speed of light. Consequently, the team is heavily focused on ultra-lightweight spacecraft architecture and innovative material designs.
