JEM-EUSO is an international collaboration for the development of space–based Ultra High Energy Cosmic Ray (UHECR) detectors. The instrument consists of a wide Field Of View (FOV) camera for the detection of the UV light emitted by Extensive Air Showers (EAS) in the atmosphere. Within the JEM-EUSO framework several pathfinders have been developed or are in course of development: EUSO-TA, EUSO-Balloon, EUSO-SPB and Mini-EUSO. For the near future the K-EUSO detector is foreseen to detect cosmic rays from space. In this paper we present the JEM-EUSO project and give an overview of the pathfinders and of their results.
