    However, according to a recent research project, the Rubin Observatory will discover but not give an adequate warning time for objects destined to hit the Earth. To provide time to take action to deflect an incoming object we will need to rely on ground based telescopes used by my Catalina Sky Survey teammates and other asteroid hunting groups as well as NASA’s NEO Surveyor satellite when it is launched.
