Tom Vice, CEO, Sierra Space
Sierra Space is a commercial space company with a legacy of nearly 30 years of experience designing, manufacturing and successfully delivering space systems, components, and spacecraft on-orbit in support of National Security.
Our Orbital Missions and Services (OMS) business area has designed, produced, and launched 23 space vehicles and supported over 400 successful space and interplanetary missions with our subsystems and components.
Building on this expertise, we are developing a next generation product line of small, high performance, affordable satellites designed from the ground up for on-orbit servicing missions.
Using commercial business models, Sierra Space is delivering capabilities faster, with a set of on-orbit commercial services including Inspection, Deorbit, Refueling, Tug/Transfer, Repair, Augmentation, Return and Connectivity.
Our goal is to deliver orbital services to commercial, DOD and national security organizations, expanding production capacity to meet the needs of constellation programs.
OMS offers turnkey on-orbit services and satellite solutions ready to integrate customer payloads.
The SN-50 ESPA class commodity buses are the baseline for purpose-built LEO/GEO Spacecraft using modular mission payloads. Sierra Space offers microsat capability with its SN-50 ESPA class LEO/GEO spacecraft platform. This product is ideal for flying smaller payloads and hosting technical demonstration missions.
Features:
The SN-100 ESPA Grande class commodity buses are the baseline for purpose-built LEO/GEO Spacecraft using modular mission payloads. The SN-100 design-for-manufacturing enables large-scale productions and increased flexibility for missions with payloads up to 150 kg.
Features:
The SN-200 ESPA Grande class commodity buses are the baseline for purpose-built LEO/MEO/GEO spacecraft using modular mission payloads.
Features:
The SN-1000 LDPE class platform can host six rideshare payloads and adds an auxiliary platform for on-orbit demo payload assets in either MEO or GEO orbits. The SN-1000 spacecraft features support refueling operations, rideshare missions, GTO to GEO transfer, multi-rendezvous and cislunar applications.
