Over The Rainbow (OTR) is Esper’s genesis orbital mission. OTR1 launched in 2024, marking the beginning of our delivery of high-quality hyperspectral imagery from space. A bridging software satellite, OTRX, has maintained data continuity between missions. OTR2 launches in August 2025, continuing the evolution of our satellite capabilities.
