This animation compares the fields-of-view of NASA's Kepler telescope and Transiting Exoplanet Survey Satellite (TESS). It begins with Kepler's first observation zone and the constellation Cygnus. It adds a single TESS camera field for comparison and then pulls back to show all four TESS camera fields, called an observation sector, and the amount of sky they cover. The sphere of the sky unwraps into a flat projection, and all the regions observed by Kepler appear. TESS's full two-year coverage appears in the proper sequence, starting in the southern hemisphere and ending in the northern hemisphere. This updated version has sectors 14-16 shifted upward to match TESS's new observing strategy. Finally, the map is rewrapped into a sphere.

This animation shows only the coverage of TESS. TESS's full two-year coverage appears in the proper sequence, starting in the southern hemisphere and ending in the northern hemisphere. This updated version has sectors 14-16 shifted upward to match TESS's new observing strategy. Finally, the map is rewrapped into a sphere. This version has no Kepler fields.

Finally, the map is rewrapped into a sphere.
