Images of comet 67P/Churyumov-Gerasimenko acquired by the OSIRIS (Optical, Spectroscopic and Infrared Remote Imaging System) imaging system onboard the European Space Agency's Rosetta spacecraft at scales of better than 0.8 meter per pixel show a wide variety of different structures and textures. The data show the importance of airfall, surface dust transport, mass wasting, and insolation weathering for cometary surface evolution, and they offer some support for subsurface fluidization models and mass loss through the ejection of large chunks of material.
由欧洲航天局罗塞塔号飞船上的 OSIRIS（光学、光谱和红外远程成像系统）成像系统拍摄的 67P/楚留莫夫-格拉希门克彗星的图像，其比例尺优于每像素 0.8 米，显示出各种不同的结构和纹理。这些数据表明，空降、表面尘埃输运、物质流失和太阳照风化对彗星表面演化的重要性，并为地下流化模型和通过喷射大量物质的质量损失提供了一些支持。
