Today’s commercial space operators face the daunting prospect of using disconnected tools with siloed workflows to design and execute successful missions. Continuum solves this problem with our platform developed by scientists from NASA’s Jet Propulsion Laboratory (JPL). Our mission is to serve our customers missions by saving time, money and data to optimize the process of going to space. Continuum streamlines the mission management process into a single unified system that supports the entire mission lifecycle from mission ideation and design to flight system design and build to launch and operations. We serve the growing space industry by enabling teams to focus on their core competencies and advance the potential of space exploration and commercialization. In 2022, we were awarded contracts with Accion, Radian, and Eternal Light. And, also secured NASA Small Business Innovation Research (SBIR) and APRA wins, among other innovation and seed funds. These projects include working to have a better understanding of black holes and ways to protect us from emerging national-defense threats in space. We are focused on democratizing space and accelerating space exploration for the benefit of humanity. One solar system, one platform.
