✅ Advantages - ⚙️ No moving mirror → more reliable, longer mission life - ⏱️ Longer dwell time per pixel → better signal-to-noise - 📦 CCDs are smaller, lighter, lower power than scanning optics - 🎯 More accurate radiometry per detector

❌ Disadvantage - 🎚️ Calibrating thousands of detectors uniformly is hard — each CCD has slightly different gain/offset
