ETH Zurich is developing a new research satellite, which aims to improve the prediction of solar storms and help prevent risks to satellites in Earth orbit. The mission, dubbed “Ethos,” is expected to launch its contribution in 2030. The new satellite will study in detail the impact of solar activity on the Earth's upper atmosphere, a process that can cause changes in the orbits of satellites and increase the risk of collisions with other space …
ETH Zurich is currently developing a new satellite to explore solar storms. "Ethos is expected to predict space weather more precisely from 2030. The satellite weighs about 25 to 30 kilograms and is equipped with several scientific instruments.
ETHOS Will Study How Solar Activity Changes Satellite Orbits
ETH Zurich is developing the ETHOS research satellite to investigate connections between solar activity, Earth’s upper atmosphere, and satellite motion. Announced on November 2, 2026, the mission is expected to begin observations in 2030. The planned spacecraft weighs 25–30 kilograms and would operate approximately 550 kilometers above Earth.
