We explore the revolutionary technologies that will propel humanity throughout our solar system and beyond.

Dr. Hakeem Ali-Bocas Alexander breaks down the propulsion systems that will transform science fiction into reality, from ion drives to solar sails and beyond.

•Discover why chemical propulsion, while powerful for launches, has limitations for long-duration space travel and how new technologies are overcoming these challenges.

•Explore the incredible efficiency of electric propulsion systems like ion thrusters, which allow spacecraft to gradually build speed over time while using minimal fuel.

•Learn about nuclear thermal propulsion, which uses nuclear reactors to heat propellant and could dramatically reduce travel time to Mars and the outer planets.

•Understand how solar sails harness the pressure of sunlight for propulsion, enabling potentially endless travel through the solar system without onboard fuel.
