How often can the THEMIS image on each orbit in circular orbit?
Once in its circular orbit the instrument will image the planet with both the visible and thermal cameras. The data rate is the constraint when it comes to how often and how many images can be obtained. If the full 10 band thermal image and corresponding 5 band visible image is taken there will be approximately 3-5 images per orbit. That number goes up if less bands are taken. Note: the thermal camera will be obtaining data on the night side of the planet too.
