ISAS Space Science Colloquium & Space Science Seminar
The JEM-EUSO program: Study of Ultra-High Energy Cosmic Rays and atmospheric events from Balloon and International Space Station
In this colloquium we will discuss the status and perspectives of the JEM-EUSO missions, carried forth by a collaboration of about 300 researchers from 16 countries, to study Ultra-High Energy comic rays, strange quark matter and terrestrial phenomena with balloon- and space-borne detectors.In particular we will discuss the recent EUSO-SPB (Super Pressure Balloon) flight. Launch took place from Wanaka, New Zealand, in April 2017. EUSO-SPB is the second balloon flight (the first one was from Canada in 2014) using Fresnel lens optics (manufactured in Riken) and Multi-Anode Photomultipliers in the focal surface. We will also discuss the MINI-EUSO mission, to be launched on board the International Space Station (ISS) in beginning 2018. MINI-EUSO is a 25cm diameter, Fresnel lens optics using a similar Focal surface to the one of SPB. It will observe the Earth from the UV-transparent window of the Russian Service module. Its main goals are the search of strange quark matter, study of meteors, Transient Luminous Effects occurring in the upper layers of the atmosphere and seach for E>5e20 eV UHECR events. Future work for a second SPB flight and the construction of K-EUSO, the first large area space UHECR observatory will also be addressed.
