Ball Aerospace successfully concluded testing on the Weather System Follow–on–Microwave (WSF-M) satellite this week, representing the completion of the first of two satellites Ball is delivering for the U.S. Space Force’s Space Systems Command next-generation operational environmental satellite system.

Ball also designed and built the Ion Velocity Meter (IVM) space weather sensors flying on five satellites in the Constellation Observing System for Meteorology, Ionosphere and Climate-2 (COSMIC-2) environmental satellite program.

Last year, Ball Aerospace was awarded a follow-on contract to build and deliver a second WSF-M satellite, which is expected to be completed in early 2026.
