The Billion Dollar Surprise: How Solar Cycle 25 Cut Satellite Lifetimes In Leo, Scott Shambaugh

Small Satellite Conference

Solar Cycle 25 has run far stronger than the 2019 consensus forecast issued by the NOAA/NASA/ISES prediction panel, with densities in low Earth orbit from 2022-2026 holding at 2-3x the predicted levels. The cumulative drag impulse experienced by LEO satellites, which is the driving metric for propellant budgets and mission lifetimes, reached 5-6 standard deviations beyond the forecast’s stated uncertainty. This means that even operators who designed conservatively against the two-sigma worst case fell short of their drag budgets. This paper quantifies a lower bound on the economic cost of that misprediction.

Starting from the 13,704 payloads on-orbit below 800 …

Small Satellite Conference

The Catarina Constellation is a Brazilian small-satellite initiative conceived to expand and modernize national space-based services through low-cost, scalable, and application-oriented CubeSat missions. Structured into mission-specific fleets, the constellation is designed to address strategic national needs while simultaneously fostering technological development and industrial capability within Brazil. Its first fleet is dedicated to environmental data collection, supporting governmental agencies and research institutions that rely on timely and reliable information for environmental monitoring, water resource management, and agricultural planning. Within this context, the Catarina-A2 mission represents a key step in the deployment of the constellation’s environmental data collection segment. Catarina-A2 is a …
