Mini-EUSO will be devoted to study the UV light emission coming from Earth. It consists of a compact telescope with a large field of view (44 × 44 sq. deg.) based on an optical system with two Fresnel lenses and an UV filter. The light is focused into an array of photo-multipliers tubes and the resulting signal is converted to digital, processed and stored via on-board electronics subsystems. To complement the observations in other wavelengths, some ancillary cameras are present: a near infrared camera, a visible camera and an array of SiPM. The additional cameras will be used to monitor the observation conditions, and to obtain complementary information on several scientific topics that will be exploited with the main telescope, such as the physics of atmosphere, meteors, and strange quark matter. Here we review the expected science and present the general outline of the control software developed to stream data from the cameras together with the main instrument, in order to grab images in an automated way.
