Italy just finished building a 24-satellite Earth-watching constellation in under a year. On Oct 1, SpaceX's Transporter-18 carried the final eight Eaglet II satellites to orbit from Vandenberg, completing the constellation and bringing Italy's IRIDE program to 39 satellites. Each microwave-oven-sized satellite has multispectral sensors and ship-tracking AIS, watching ground motion, fires, coasts and air quality. Swipe through: the launch stack, the constellation at work, the hardware up close.
