TESS is equipped with four wide-field cameras that allow it to monitor large sections of the sky for transiting exoplanets. Each camera has a 24° by 24° field of view, and together they cover a 96° by 24° strip of the sky. TESS observes one strip for about 27 days before rotating to the next, covering nearly the entire sky over its two-year primary mission. The data collected is then analyzed to identify periodic dips in star brightness which could indicate the presence of an exoplanet.
