Open Cosmos launches first satellites for Balearic Islands, Greece
Open Cosmos
Open Cosmos launched Posidonia, the Balearic Islands' first satellite, and Hyperion GR-1, the first of a planned Greek EO constellation.
what happened
British-based Open Cosmos launched Posidonia, the first satellite built for Spain's Balearic Islands regional government, and Hyperion GR-1, the first of seven planned satellites for a Greek Earth observation constellation, aboard SpaceX's Transporter-17 rideshare mission on July 7. Posidonia is co-funded by the Balearic regional government using European funds and is described as the initial deployment of Open Cosmos' own Open Constellation 1.0, intended to deliver land-use, emergency-response, and climate data within four hours of tasking.
why it matters
Both satellites extend the trend of regional and national governments in Europe commissioning dedicated sovereign EO capacity from a single manufacturer rather than buying imagery on the open market, echoing the ICEYE deals already on this site with Portugal and Norway. For Open Cosmos, delivering two sovereign-government satellites on one rideshare mission is a concrete data point for its build-to-order EO business outside the UK.
