Just wondering how Rubin affects the problem of asteroids being detected late.

Afaik it's not unusual for truck-sized objects to woosh past Earth, detected only after their pass. Or just days before. Weeks if lucky. Not a timespan in which one could mount a divert-mission.

Possibly this applies to bigger objects too? Some objects have a very dark surface & are very hard to detect in any case.
