China and Ukraine Collaborate on New Tech to Monitor Asteroid Threats

A collaborative research team from China and Ukraine has developed the rotating-drift-scan (RDS) charge-coupled device (CCD) technique, significantly improving the accuracy of monitoring near-Earth asteroids (NEAs). This innovation enhances the precision of orbit determination, crucial for assessing collision risks and planning deflection missions. The technique's success underscores the importance of international collaboration in addressing global challenges like planetary defense.
