ESA launches Thales Alenia‑built IOD‑2 pair for Celeste LEO navigation demonstrator

Two Thales Alenia‑built IOD‑2 satellites for the European Space Agency’s Celeste in‑orbit demonstration were launched on a Rocket Lab Electron from New Zealand at 10:14 CET and separated about an hour later. The pair will test a complementary LEO navigation layer intended to improve positioning accuracy and integrity.

Solar Orbiter reveals wave-driven energy transfer in the solar wind ESA's Solar Orbiter has captured the clearest observations yet of wave structures embedded in the solar wind, revealing how these waves shuttle energy between charged particles as the wind expands outward from the Sun. The measurements clarify fundamental processes shaping near-Sun plasma dynamics and space-weather drivers.
