Light sails are a promising method for traveling through space - indeed, Breakthrough Starshot proposed a laser driven version could reach nearby stars. But the exorbitant costs and engineering challenges of such a proposal have stymied its realization. What if there was a way of using the Sun - no lasers required - but keeping our dream of interstellar travel in tact? Introducing TARS. This video is based on published research (see https://arxiv.org/abs/2507.17615 ) supported by the Cool Worlds donors (see below).
