Fission Surface Power (FSP)

Powering space outposts

Inherently safe reactor 
with integral steam generator
Enabling Lunar and Martian Missions with Reliable Nuclear Surface Power

Future missions to the Moon and Mars will be establishing outposts that support human life and supply reliable energy for activities such as mining, water extraction, research and other supporting activities.

Nuclear energy is the most viable power source for these missions, offering high energy density, consistent performance, and the ability to operate independently of sunlight.

With a legacy in nuclear energy, cutting-edge reactor and materials development, and deep experience in space systems, General Atomics Electromagnetic Systems (GA-EMS) is actively exploring technologies to power human outposts on the Moon, Mars, and beyond.
