ESA weighs switching Harmony satellites from Vega C to a two-booster Ariane 6 ESA is considering moving its two Harmony satellites off Vega C and onto a two-booster Ariane 6 configuration. The review highlights how ESA is actively balancing launch-vehicle options as it prepares the Harmony mission, potentially changing the mission’s lift profile and launch-provider mix.

ESA sterilises ExoMars Rosalind Franklin descent parachute to enable Mars touchdown ESA has completed sterilisation of the ExoMars parachute set that will slow the Rosalind Franklin rover’s descent for a safe touchdown on Mars. ESA’s Mars chief engineer Albert Haldemann walked through the sterilisation approach and why it’s critical to mission success for the rover’s environment-sensitive landing phase.

ESA’s Proba-3 coronagraph begins solar-wind tracking, enabling source-linked space-weather observations ESA says its Proba-3 formation-flying coronagraph is tracking space weather back to its origin, a first for the mission architecture. The system’s eclipse-style observations are aimed at improving how solar wind features are observed and attributed to their source regions.
