The EUSO-SPB2 mission*

The Extreme Universe Space Observatory Super Pressure Balloon mission Two(EUSO-SPB2) is in preparation. The planned launch date is 2021. This balloon mission will serve as a test of techniques and methods for the Probe of Extreme Multi Messenger Astronomy (POEMMA) space mission currently under a NASA sponsored conceptual design. A science payload of up to three optical cosmic ray telescopes are planned for this long duration mission. Two of them are designed to detect direct Cherenkov light near the direction of the Earth’s limb, while the third one uses the fluorescence technique to measure near horizontal showers. SPB2 will feature advanced optics and electronics, as well a more mature design than its predecessor SPB1. To understand the effect of these improvements, reconstructions are done on simulated air showers. We present the preliminary results of the simulations, and expected performance gains relative to SPB1.
