The project was funded by a Phase II grant of NASA Innovative Advanced Concepts (NIAC), which funds the most promising ideas for the next generation NASA space missions.

Conducted in a Class 1,000 cleanroom, Y.K. Bae's demonstration amplified photon power 400-times to achieve photon thrust up to 1.1 milliNewtons by bouncing photons several hundred times between two laser mirrors. The amplified thrust successfully propelled a gliding platform along a 2 meter frictionless air track, simulating zero-gravity.
