As it sweeps across the night sky from its outward-facing position on the International Space Station, the ISS Surveyor instrument captures 16°x24° image frames from each of its 20 cameras. The instrument is designed to use on-the-edge computing for data analysis and reduction in orbit. We also download raw images as part of our 10 GB/day data downlink. These images are used to develop, benchmark, and test our in-orbit algorithms. Here we have stacked most of those images into an all sky mosaic to demonstrate the sweeping field of view ISS Surveyor has covered since its first light on December 27, 2025. This mosaic currently includes 3716 images from 19 cameras spanning griz filters.
The native resolution of Surveyor images is 9.36 arcsec/pixel. The mosaic above (luminance) and below (RGB) is 5.6 arcmin/pixel for 4k resolution (3840 x 2160). Higher resolution versions are provided for download:
14 arcsec/pixel (92572 x 46286, 812.8 MB [luminance])
42 arcsec/pixel (30857 x 15429, 127.6 MB [luminance] | 190.2 MB [RGB])
