Summary

Story summary

The Rubin telescope's detection failures stem from infrequent revisits to the same sky area, hindering asteroid confirmations.
As a result, many mid-sized and large objects are lost because the telescope cannot track them adequately.
Small objects remain undetected until they approach Earth, often becoming visible too late for response.
The telescope captures images of potential threats, but without follow-up, sightings do not yield confirmed orbits.
