“…The balloon was launched from Timmins, Canada, and the flight lasted for around 8 hours. The camera was triggered with a 20 Hz frequency, recording UV light background levels [8] as well as artificial sources (UV flashers and UV laser) from a helicopter [9]. The detector came down in a small lake and the instrument was recovered intact allowing reuse the instrument after extensive upgrades for the 2017 long duration balloon flight.…”

The latest and most advanced effort towards a space-based optical cosmic ray detector developed within the Joint Experiment Mission for the Extreme Universe Space Observatory (JEM-EUSO) collaboration was the Extreme Universe Space Observatory on a Super Pressure Balloon (EUSO-SPB1) mission. The EUSO-SPB1 instrument looks for UV light emitted by extensive air showers above the detectors energy threshold of 3 EeV. This detector was launched in 2017 out of Wanaka, New Zealand as a mission of opportunity on a NASA SPB. Over 27 hours of data was taken in air shower detection mode during the 12-day flight over the Pacific Ocean. Besides an overview of the instrument and the mission details, we will show the results of the data analysis of the flight. Methods to search for tracks and other interesting signals were developed and applied to the flight data set revealing different types of events. But no obvious track of a cosmic ray candidate was found. This result is in agreement with a detailed simulation study performed after the flight to include the different conditions. Data of the flown IR camera and weather forecast model were used to determine the cloud conditions within the telescopes FoV. The presented results are also discussed in various separate contributions at this conference. The experience gained during this flight is essential for the preparation of the follow-up mission EUSO-SPB2 which is planned to launch in 2022.

The Extreme Universe Space Observatory on a Super Pressure Balloon II Mission (EUSO-SPB2) is a precursor for a next generation space observatory for multi-messenger astrophysics. The EUSO-SPB2 instrument will measure PeV and EeV-scale cosmic rays, optical backgrounds that could mimic tau neutrino interactions in the Earth's limb, and search for optical signatures consistent with the upward-going candidate events that the Antarctic Impulse Transient Antenna (ANITA) reported. The payload, now in the design and fabrication stage, features a pair of optical telescopes that have 1 meter diameter apertures. The Fluorescence Telescope will have sensitivity in the UV to target extensive air showers at EeV energies. The Cherenkov Telescope will have UV/VIS sensitivity to target Cherenkov emission from air showers at PeV energies. The planned launch date is 2022. We discuss the science and mission, and the current status.

“… The EUSO‐TA experiment aimed to demonstrate the capability of a UV telescope with a conceptual design similar to the one to be located on the ISS in detecting air showers. It is ground based and has been installed at the Telescope Array site in the desert of Utah, USA, in 2013 and it is still in operation, with ongoing plans to upgrade it. The EUSO‐Balloon experiment launched on a stratospheric balloon in August 2014, from Timmins (Canada, Ontario), was an engineering mission with the aim of increasing the Technical Readiness Level (TRL) of the hardware in near‐space conditions and performing an estimation of the UV background by observing the Earth's UV emission from the sky. The EUSO‐SPB experiment is the evolution of EUSO‐Balloon; it was designed for a long duration balloon mission using a Super‐Pressure Balloon technology. It was launched by NASA on April 24, 2017 from Wanaka, New Zealand.…”

In this paper, the flight software architecture of the EUSO-SPB mission is described. The JEM-EUSO program aims at developing an advanced large space-borne UV telescope designed to detect ultra high energy cosmic rays. In this framework, the EUSO-SPB experiment is the third pathfinder mission of the JEM-EUSO program, the second that has been launched on a stratospheric balloon to test the technological readiness of the detectors and to carry out some preliminary scientific observations. The EUSO-SPB software has a modular structure conceived to control all the instruments and the ancillary subsystems, to acquire data, and to manage data transfer to ground. System programming in C and C++ languages and Bash scripts have been used to implement and run the modules. The software runs on the data processor, an onboard computer that communicates with several payload blocks, the UV sensor, and the synchronization and time tagging board. The control software module controls all the subsystems, provides communication to ground through the NASA telemetry or the Internet, runs the acquisition control and download software, and manages the execution of the acquisition software. The acquisition software module directly operates the subsystems for the data acquisition activity. The acquisition control and download software module runs the acquisition software upon request of the control software and transfers scientific data to ground. The software system performed as expected during the flight on April 2017.
