Photonic Propulsion: Mars in 3 Days?

The video discusses photonic propulsion, a technology using lasers to propel spacecraft, potentially enabling travel to Mars in days and to exoplanets. Current chemical propulsion is insufficient for interstellar travel, but photonic propulsion could achieve near-light speeds. The Deep In project aims to develop this technology, with D Star focusing on laser arrays for propulsion and asteroid defense. Challenges include building large laser arrays and thin, strong sails. Initial steps involve smaller laser arrays and wafer-sized spacecraft, with potential to reach Alpha Centauri in 15 years.
