Descripción
Precise observations of near-Earth asteroids (NBAs) are critical for ex tending observational arcs, refining their orbits, and ensuring Earth’s safety through accurate impact prediction. However, their high apparent motion during close Earth encounters presents a significant challenge to precise ob servation. The rotating-drift-scan (RDS) charge-coupled device (CCD) tech nique offers a promising solution for observing these fast-moving NBAs during close approaches. By rotating the telescope camera, time delay integration is enabled, allowing the NBA to be imaged as a point source despite long exposure times.
