SST – The Next Asteroid Hunter
Design combines rapid step-and-settle, significant aperture, and wide field-of-view

SST Asteroid Discovery Potential
• Performing simulations of small NEO detection with SST
• SST asteroid survey planning underway
Simulations suggest that a dedicated SST asteroid survey should be able improve our knowledge of the NEO size distribution
