An immersive 3D simulation of planets, moons, and their orbits—bringing Hewa+ app functionalities directly to your browser for interactive space learning.
Welcome to the ESSS Science Portal — a free interactive learning environment built by the Ethiopian Space Science Society to make space science intuitive and accessible for students, educators, and space enthusiasts.
Our interactive 3D simulators empower students, teachers, and space school clubs across Ethiopia to explore orbital physics, lunar topography, and astronomical principles hands-on directly in their web browsers.
From calculating local solar eclipse totality pathways over East Africa to tracking low Earth orbit satellites in real time, the ESSS Science Portal equips space enthusiasts and university students with high-precision research tools.
By bringing complex astrophysical simulations, 3D orbital mechanics, and real satellite telemetry into an intuitive web platform—built with functionalities adapted from the official Hewa+ app—the ESSS Science Portal bridges the gap between theoretical textbook formulas and practical, visual discovery.
