“…The design of the POEMMA observatory evolved from previous work on the OWL 3 and JEM-EUSO 4 designs, the CHANT concept 5 , and the sub-orbital payloads EUSO-SPB1 6 and EUSO-SPB2 7 . POEMMA is composed of two identical space telescopes that provide significant advantages in terms of exposure and sky coverage to sources of the highest energy particles.…”

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) mission is being designed to establish charged-particle astronomy with ultra-high energy cosmic rays (UHECRs) and to observe cosmogenic tau neutrinos (CTNs). The study of UHECRs and CTNs from space will yield orders-of-magnitude increase in statistics of observed UHECRs at the highest energies, and the observation of the cosmogenic flux of neutrinos for a range of UHECR models. These observations should solve the long-standing puzzle of the origin of the highest energy particles ever observed, providing a new window onto the most energetic environments and events in the Universe, while studying particle interactions well beyond accelerator energies. The discovery of CTNs will help solve the puzzle of the origin of UHECRs and begin a new field of Astroparticle Physics with the study of neutrino properties at ultra-high energies.

“…Finally, we estimated the angular resolution (α err rec ) to be better than 2.2°for the conditions during the field tests while using the laser position as a constraint. The collaboration is preparing a follow-up mission, EUSO-SPB2 [20] with an anticipated launch date of March 2022. This new instrument will be equipped with two telescopes using Schmidt optics, expecting a higher light collection efficiency.…”

The Extreme Universe Space Observatory on a Super Pressure Balloon 1 (EUSO-SPB1) instrument was launched out of Wanaka, New Zealand, by NASA in April, 2017 as a mission of opportunity. The detector was developed as part of the Joint Experimental Missions for the Extreme Universe Space Observatory (JEM-EUSO) program toward a space-based ultra-high energy cosmic ray (UHECR) telescope with the main objective to make the first observation of UHECRs via the fluorescence technique from suborbital space. The EUSO-SPB1 instrument is a refractive telescope consisting of two 1 m 2 Fresnel lenses with a high-speed UV camera at the focal plane. The camera has 2304 individual pixels capable of single photoelectron counting with a time resolution of 2.5 µs. A detailed performance study including calibration was done on ground. We separately evaluated the properties of the Photo Detector Module (PDM) and the optical system in the laboratory. An end-to-end test of the instrument was performed during a field campaign in the West Desert in Utah, USA at the Telescope Array (TA) site in September 2016. The campaign lasted for 8 nights. In this article we present the results of the preflight laboratory and field tests. Based on the tests performed in the field, it was determined that EUSO-SPB1 has a field of view of 11.1 • and an absolute photo-detection efficiency of 10%. We also measured the light flux necessary to obtain a 50% trigger efficiency using laser beams. These measurements were crucial for us to perform an accurate post flight event rate calculation to validate our cosmic ray search. Laser beams were also used to estimated the reconstruction angular resolution. Finally, we performed a flat field measurement in flight configuration at the launch site prior to the launch providing a uniformity of the focal surface better than 6%.

“…Two stratospheric balloon flights have been performed in the past: the EUSO-Balloon [3] for one night in 2014 and the EUSO-SPB1 [4] for 12 days in 2017. A follow-up mission, EUSO-SPB2 [5], is in preparation for a third balloon flight in 2021-22. The Mini-EUSO detector [6] is planned to fly on August 22 nd 2019 onboard the International Space Station (ISS) to map the emission in the UV from space.…”

The origin of Ultra-High Energy Cosmic Rays (UHECRs) remains unsolved in contemporary astroparticle physics. The objective of the JEM-EUSO program is the realization of a space mission devoted to UHECR physics. Several detectors have been developed in this framework or are under development. EUSO-TA, installed at the Telescope Array site in Utah in 2013, is in operation. It has detected 9 UHECRs in coincidence with Telescope Array fluorescence detector at Black Rock Mesa. EUSO-Balloon flew on board a stratospheric balloon in August 2014. It measured the UV intensity on forests, lakes and cities as well as proved the observation of UHECR-like events reproduced by laser tracks. EUSO-SPB1 was launched on board a super pressure balloon on April 24th 2017 and flew for 12 days. It proved the functionality of all the subsystems of the telescope on a long term and observed the UV emission on oceans. TUS, on board the Lomonosov satellite, in orbit since April 28th 2016, is now included in the JEM-EUSO program and has detected so far in the UHECR trigger-mode a few interesting signals. Mini-EUSO is in its final phase of integration in Russia, and is scheduled for launch on August 22 nd . The main results obtained so far by these missions are summarized and put in the perspective of future space detectors such as K-EUSO and POEMMA.
