  19. Conclusions • Collision has significant long-term adverse effects • International community must continue to work to mitigate debris generation • Can mitigate risk by collaboratively sharing SSA • SOCRATES-GEO: 11 operators, 150 satellites • SOCRATES-LEO: 6 operators, 106 satellites • Need best available SSA from SSN • Need full examination of this event to help chart the way ahead
