Spire Global Successfully Launches 9 Satellites on SpaceX’s Twilight Mission

Key Terms

hyperspectral microwave sounder technical

A hyperspectral microwave sounder is a satellite instrument that reads faint microwave signals from the atmosphere at many closely spaced frequencies to build detailed vertical profiles of temperature, humidity and precipitation. Think of it as a multi-color thermometer that sees through clouds to reveal weather layers; investors care because improved, earlier and more accurate weather and climate data can reduce uncertainty for agriculture, energy, shipping and insurance forecasts, affecting revenues and risk models.

radio occultation technical

Radio occultation is a technique that uses a signal from a satellite or spacecraft as it passes behind Earth to sense how the planet’s atmosphere bends and slows that signal, like watching how a flashlight beam dims and blurs when it shines through fog. The measured changes reveal temperature, humidity and ionospheric conditions with high precision, which investors care about because better weather, climate and positioning data improve forecasting, supply-chain planning, agricultural yields and insurance risk models.

iot technical

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

Launch includes next-generation hyperspectral microwave sounder to advance global weather forecasting

VIENNA, Va.--(BUSINESS WIRE)-- Spire Global, Inc. (NYSE: SPIR) (“Spire” or “the Company”), a leading global provider of satellite data, analytics, and intelligence, successfully launched nine satellites aboard SpaceX’s Twilight mission from Vandenberg Space Force Base.

Advancing Global Weather Forecasting with Next-Generation Hyperspectral Technology

As part of the mission, Spire launched its Hyperspectral Microwave Sounder (HyMS) 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.

“Microwave sounding is one of the most impactful satellite observations for weather forecasting models worldwide, alongside radio occultation profiles,” said Theresa Condor, CEO of Spire Global. “This area represents a multi-billion-dollar global atmospheric sounding need, driven by the essential role these observations play in delivering accurate temperature and moisture profiles, particularly in cloudy conditions. With the successful launch of our Hyperspectral Microwave Sounder demonstrator, we are proud to strengthen our ability to support global forecasting agencies and further enable efficient and effective private sector participation in the global observing system.”

Expanding Myriota’s Space-Based IoT Network

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.

Since partnering in 2021, Myriota has scaled its IoT connectivity platform rapidly by deploying its network software on Spire satellites that are optimized to host and run Myriota’s advanced network in space. The continued expansion strengthens Myriota’s ability to deliver low-power, secure, and resilient IoT connectivity serving industries such as agriculture, water management, logistics, and environmental monitoring.

“By working closely with Spire to expand our presence in this orbit, we’re delivering meaningful improvements for customers – faster message delivery, greater reliability, and stronger overall network performance. This investment marks a new level of Ultralight Network capability for Myriota customers worldwide,” said Paul Alexander, Chief Network Officer at Myriota.
