Online Event

The Breakthrough Starshot Initiative established in 2016 sets an audacious goal of sending a spacecraft beyond our Solar System to a neighboring star within the next half-century. In this mission concept, an ultralight spacecraft will be accelerated by laser radiation pressure from an Earth-based source to ~20% of the speed of light, making use an ultrathin lightsail membrane to harvest the photon pressure during acceleration. The first phase of lightsail research and development was initiated in 2018. This webinar will present an overview of key developments that have occurred through this and related efforts which are paving the way for realization of the Starshot concept.
