In a rapidly expanding Space sector delivering Security with Economic benefits, how do we work towards space sustainability? The pace of change in the space economy is as fast as ever, with no sign of slowing down. That puts tremendous pressure on how to sustain the space environment to properly support increasing activities related to security and economic expansion. The world is shifting dramatically with direct impacts on security, space, and the demand for growing defense aspects of space — including GOLDEN DOME — that bring great expectations for the space economy. We are moderating the Space Sustainability plenary at Space Ops 2025, in Montreal on May 29th at 8:30am and we are continuing this discussion with our expert panel as part of our Our Future in Space series hosted at our headquarters.
