9 – Riding Ions (feat. Joe Cassady)

Electric vehicles aren't just taking over our roads - they're taking over our orbits, too! Solar electric propulsion is a cutting edge technology that allows spacecraft to change velocity up to an order of magnitude more efficiently than traditional chemical rockets. Joe Cassady from Aerojet Rocketdyne and Explore Mars talks with us about how this propulsion works, it's power requirements, the development status, and how we'll use it to eventually send cargo to Mars in support of human exploration.
