NASA's Solar Electric Propulsion (SEP)

NASA's Solar Electric Propulsion (SEP) is a technology that uses electricity generated from solar panels to propel spacecraft. Instead of traditional rocket fuel, SEP employs ion thrusters that create thrust by accelerating ions, which are charged particles. This method is efficient and allows spacecraft to travel further and faster in space. By gradually building up speed over time, SEP is ideal for long-duration missions, such as exploring asteroids or distant planets. This innovative propulsion system helps reduce the weight of fuel and minimizes the environmental impact compared to conventional chemical propulsion methods.
