  "abstract": "In the present-day cosmic ray data, the strongest indication of anisotropy of the ultra-high energy cosmic rays (UHECRs) is the 20-degree hotspot observed by the Telescope Array with the statistical significance of 3.4{\\sigma}. In this work, we study the possibility of detection of such a spot by space-based all-sky observatories. We show that if the detected luminosity of the hotspot is attributed to a physical effect and not a statistical fluctuation, the KLYPVE and JEM-EUSO experiments would need to collect ~300 events with E>57 EeV in order to detect the hotspot at the 5{\\sigma} confidence level with the 68% probability. We also study the dependence of the detection prospects on the hotspot luminosity.",
