The comment above is deceptive. It’s technically correct, because the sensor is capturing data from a reflection of a curved mirror. IIRC it’s actually two reflections, so the imaging device is facing forward still. This is how most telescopes work though. In the same way, it’s accurate to say “this is how mirrors work” but that doesn’t sound impressive. It’s just a reflection.
