Fuseki develops a constellation of deep‑space CubeSats that can be redirected to newly identified asteroids within a month for both scientific study and planetary‑defense missions.

Current asteroid observation and planetary‑defense missions rely on large spacecraft and lengthy development cycles, resulting in response times of months to years after a new object is discovered. This delay limits timely scientific study and reduces the effectiveness of mitigation actions against potentially hazardous asteroids.
Fuseki builds a constellation of deep‑space CubeSats that can be retargeted to any newly identified asteroid in less than one month. Each spacecraft uses machine‑learning‑driven autonomous navigation to compute and execute precise trajectory adjustments on board, eliminating the need for ground‑based replanning. Optimized propulsion burns minimize propellant consumption while achieving rapid, high‑precision retargeting. During a flyby, the CubeSats approach within tens of kilometres, acquiring high‑resolution visible‑spectrum imagery and multiband spectral measurements for detailed remote‑sensing analysis. The modular, low‑cost design enables frequent, repeatable missions, providing a scalable platform for both scientific exploration and rapid planetary‑defense response.
Primary customers are national space agencies, planetary‑defense organizations, and research institutions that require fast, low‑cost access to small bodies for scientific or hazard‑mitigation purposes. Commercial entities interested in asteroid prospecting also benefit from the rapid‑response observation capability.
