Sierra Space Launches its Innovative Eclipse Satellite Bus Line

Sierra Space, one of the leading commercial space-tech companies and next generation defense-tech prime building a platform in space to benefit life on Earth and protect the freedom of economic activity in the Orbital Age, announced the launch of its innovative Sierra Space Eclipse satellite bus line.

This cutting-edge series sets a new standard in earth observation, servicing, mobility, logistics and communications. The Sierra Space Eclipse bus line comprises three distinct classes tailored to a wide range of missions: Eclipse Velocity, Eclipse Horizon, and Eclipse Titan, each designed to meet the rapidly evolving demands of the modern space industry.

“At Sierra Space, we are committed to innovating at speed,” said Sierra Space CEO Tom Vice. “The Sierra Space Eclipse line is a testament to our dedication to innovation, offering scalable solutions that can meet the needs of tomorrow's space missions today. With Velocity, Horizon, and Titan, we are not just launching satellites; we are launching a new era of space commercialization.”

Eclipse Velocity

Revolutionizing the highly maneuverable small satellite sector, the Eclipse Velocity is a marvel of engineering, offering unparalleled efficiency and agility in a compact form. Designed for Low Earth Orbit (LEO), Medium Earth Orbit (MEO) and Geosynchronous Earth Orbit (GEO) missions, with integrated Rendezvous, Proximity Operations and Docking (RPOD) capabilities and full 6-DOF controls. Velocity is a fully refuellable system designed for dynamic space operations. Eclipse Velocity makes space more accessible than ever before.

Eclipse Horizon

The high-rate production satellite of the Eclipse line, Eclipse Horizon is a versatile medium-class bus designed for a broad spectrum of missions, from missile warning and defense, advanced Earth observation, and communications. Eclipse Horizon stands as a beacon of reliability, affordability, and high-performance enabling horizon-to-horizon coverage for government and commercial constellation missions.

Eclipse Titan

Dominating the skies, the Eclipse Titan is the pinnacle of satellite technology. A large-class bus with unmatched capabilities, it is destined for high-demand tasks such as Cis-lunar, Geosynchronous Earth Orbit (GEO) logistics, on-orbit re-fueling, mission support and satellite deployment. Eclipse Titan embodies the spirit of ambition and exploration that drives Sierra Space.

The Sierra Space Eclipse series represents a significant leap forward in satellite technology, featuring state-of-the-art propulsion systems, integrated rendezvous, proximity operations and docking, advanced communication capabilities, and robust power management. All capabilities are housed within scalable platforms that can be customized to unique mission requirements as a tailorable bus or as a fully integrated spacecraft.

“Our Sierra Space Eclipse product line is manufactured in a high-rate production system, with the ability to be refuellable on orbit, enabling the next generation of satellites designed for dynamic space operations,” added Erik Daehler, Vice President of Sierra Space Orbital Missions and Services.

Sierra Space has a legacy of nearly 30 years of experience designing, manufacturing and successfully delivering space systems, components, and spacecraft on-orbit. The company’s Orbital Missions and Services team has designed, produced, and launched 23 space vehicles and supported more than 400 successful space and interplanetary missions with subsystems and components.
