Over the rainbow
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 launched in August 2025, continuing the evolution of our satellite capabilities.
Four Leaf Clover
In 2026, our Four Leaf Clover hyperspectral mission will introduce a major leap forward in spectral resolution, calibration stability, and imaging performance. Built to deliver richer, cleaner, and more continuous spectral data, Four Leaf Clover gives exploration, environmental, and monitoring teams a sharper view of the Earth’s surface and its chemical makeup.
The Esperoko, the sensor behind our Four Leaf Clover missions, is being made available to support sovereign scientific and intelligence satellite missions.
