Spire Global successfully launches nine satellites on SpaceX’s Twilight mission

Spire Global (SPIR) successfully launched nine satellites aboard SpaceX’s Twilight mission from Vandenberg Space Force Base. As part of the mission, Spire launched its Hyperspectral Microwave Sounder satellite demonstrator, a compact, space-ready sensor built to advance global weather forecasting from space. HyMS is designed to capture detailed internal views of the Earth’s atmosphere, measuring important atmospheric variables including temperature, humidity, and precipitation. As a first-of-its-kind hyperspectral microwave mission, it will aim to help forecasters better understand how weather systems form and evolve in real time. On this mission, the company also launched eight satellites for Myriota, expanding the IoT provider’s constellation and global space infrastructure to enable more scalable and reliable IoT connectivity for smart devices worldwide. This launch delivers an uplift in performance and resilience across Myriota’s IoT network.
