THEMIS scans Phobos
This sequence of 19 images was taken in visible-wavelength light as the Thermal Emission Imaging System (THEMIS) camera on NASA's Mars Odyssey orbiter scanned across the Martian moon Phobos. THEMIS also recorded thermal-infrared imagery during the same scan. The apparent motion is due to progression of the camera's pointing during the 18-second span of the Sept. 29, 2017, observation, not from motion of Phobos. Timing is sped up by a factor of two in this animation. This was the first observation of Phobos by Mars Odyssey.

Most NASA images are in the public domain. Reuse of this image is governed by NASA's image use policy.

Original image data dated on or about September 29, 2017
