CIVA (Comet nucleus Infrared and Visible Analyzer) Six identical micro-cameras take panoramic pictures of the surface. A spectrometer studies the composition, texture and albedo (reflectivity) of samples collected from the surface. CIVA-P, without the lens used on rosetta and philae similar panoramic camera is also used in tianwen-1 the imager on the lander (rather, one of the imaging systems on the lander). It was a visible light camera system with 7 mini-cameras which produced the panoramic view of the landing site. Another imager provided IR data for compositional analysis. this explains a lot of questions to tianwen-1 mission!! space-x from switzerland swiss eye unmannedspaceflight universetoday
