Weather intelligence company Tomorrow.io said on Thursday it plans to deploy a new space-based weather monitoring constellation called DeepSky, designed to deliver higher-frequency atmospheric observations and improve global and regional weather forecasting, including predictions of extreme events.
The announcement follows the completion of Tomorrow.io’s first-generation satellite constellation, which now has 11 satellites in orbit equipped with Ka-band radar and microwave sounders. Earlier this month, the company launched two satellites aboard SpaceX’s Twilight rideshare mission.
Tomorrow.io did not disclose how many satellites will ultimately comprise the DeepSky constellation, nor did it provide a timeline for the first launch. The company said deployment will occur in phases and that development is already under way.
“The world has been forecasting weather and assessing risk with incomplete information for too long — training models on simulations because the observations simply didn’t exist,” said Rei Goffer, co-founder of Tomorrow.io. “DeepSky changes that equation. We’re building the infrastructure to finally see the atmosphere as it actually behaves, giving every industry the confidence to act decisively when it matters most.”
Tomorrow.io said existing government-operated weather satellites are constrained by limited revisit times, which can leave gaps in rapidly evolving weather systems. DeepSky is intended to complement those assets by providing higher-cadence observations and introducing new sensing approaches to capture atmospheric dynamics more frequently.
According to the company, DeepSky satellites will carry multimodal sensors capable of scanning across the full electromagnetic spectrum at high temporal resolution. This data is expected to support faster-refresh numerical weather models and power new AI-native applications built on real-world atmospheric observations rather than simulations.
The company said the constellation is expected to serve a broad range of users, including civilian meteorological agencies, severe weather and hurricane forecasting centers, defense and national security organizations, and international partners.
Tomorrow.io positions DeepSky as part of a broader shift toward commercial space-based infrastructure playing a larger role in weather intelligence, particularly as climate volatility increases demand for more precise, real-time forecasting across sectors such as aviation, energy, logistics and emergency management.
