Hyperspectral Microwave Sounder Set for Launch Following Final Testing Phase

Spire Global, Inc. has completed environmental testing, calibration, and flight qualification for its Hyperspectral Microwave Sounder (HyMS) payload, which is now integrated into a Spire 16U satellite and shipped to Vandenberg Space Force Base for launch aboard SpaceX's Falcon 9 Twilight mission.

The HyMS payload will serve as a technology demonstrator, aiming to validate the function of a hyperspectral microwave sounder in a compact satellite platform. HyMS is designed to provide detailed temperature, humidity, and precipitation profiles by sensing atmospheric microwave signals with high spectral resolution.

Engineers subjected the sounder to extensive thermal vacuum testing, simulating the space environment.
