The Space Option Star (S⊕S) is a Space Solar Power (SSP) demonstrator and an orbital artwork which represents a logical early step in the Astrostrom development program.

The S⊕S mission has a dual purpose:

1. Its technical mission represents an in-situ demonstration of energy from space technologies
2. Its communication mission is to raise public awareness about the potential of the Space Energy Option to address the Energy Dilemma and the Climate Emergency

201 ideas were submitted in ESA’s 2020 call for new mission ideas. S⊕S was one of four energy from space projects selected for further evaluation.
