SAN FRANCISCO — In a major expansion of its high-orbit satellite deployment strategy, satellite manufacturer and operator Astranis announced today that it has upgraded its fourth launch agreement with SpaceX into a fully dedicated mission. Scheduled for liftoff in 2028, the flight will be carried out aboard a SpaceX Falcon 9 rocket and will transport an entire production run of the company’s advanced spacecraft in a single go.
The upcoming 2028 mission will carry a total of six MicroGEO satellites representing the complete "Block 4" production run. According to the company, these spacecraft will be placed directly into geostationary orbit (GEO) through the use of an Impulse Helios upper stage. This direct-injection method enables the satellites to reach their operational orbital slots efficiently, allowing Astranis to rapidly expand its global footprint and enhance its capacity to serve an expanding roster of commercial and government clients worldwide.
Once successfully deployed, this dedicated flight will expand the total size of the active Astranis fleet to 16 satellites. This new milestone builds directly upon the 10 spacecraft previously constructed and deployed across the company’s preceding Block 1, Block 2, and Block 3 programs. Although the company has already secured several initial customers for the upcoming Block 4 satellites, specific announcements regarding these partnerships are slated to be revealed at a later date.
The newly finalized arrangement represents a direct amendment to an initial launch contract that Astranis originally signed with SpaceX in late 2024. By upgrading the terms of the agreement, Astranis has secured the entire payload capacity of the Falcon 9 mission, a move that highlights the company’s increasing cadence and its reliance on dedicated launch solutions to meet surging demand.
Securing dedicated launch windows for multi-satellite batches has emerged as a fundamental advantage of the Astranis responsive business model. In an era where commercial enterprises and sovereign governments increasingly require rapid access to space, the ability to deploy entire blocks of satellites at once provides the necessary capacity to support booming demands for dedicated space infrastructure.
Across the globe, government agencies and major commercial enterprises are pivoting away from shared capacity models. Instead, these entities are actively seeking dedicated space infrastructure for vital communications and emerging missions, such as space domain awareness. By owning and operating dedicated assets, these organizations retain full control over their networks, a security and operational requirement that higher orbits like geostationary earth orbit are uniquely suited to fulfill.
John Gedmark, CEO and co-founder of Astranis, emphasized the strategic importance of the upgraded SpaceX contract in addressing broader market trends. "We’ve only just begun to ramp up production to meet the demand we are seeing for commercial and national security missions," said Gedmark. "This launch means we can accelerate the critical infrastructure we’re building for customers in GEO and other higher orbits."
The newly expanded launch contract marks another significant step forward in Astranis’ ongoing efforts to scale high-orbit infrastructure. This announcement closely follows the recent introduction of Perceptor, a new capability designed to extend the company’s operational reach beyond traditional telecommunications. Perceptor focuses on space domain awareness and maneuverability, catering directly to the specialized needs of both commercial operators and national security customers.
Having initially proven that high-performance geostationary satellites could be manufactured faster and at a much larger scale than traditional, multi-ton GEO spacecraft, Astranis is now actively developing broader high-orbit platforms. These platforms are engineered to connect, safeguard, and sustain critical infrastructure operating within the geostationary belt.
Founded with the mission of building advanced satellites for high orbits to expand humanity’s reach into the solar system, Astranis currently provides dedicated, secure networks to a sophisticated global clientele. Its primary customers include large commercial enterprises, sovereign governments, and the United States military, all of whom require high-uptime, secure communications architectures.
With multiple satellites already actively operating on orbit and serving customers across the globe, the company is currently servicing a commercial backlog valued at more than $1 billion. Astranis has positioned itself as a preferred satellite communications partner for buyers who maintain stringent requirements regarding network uptime, data security, end-to-end network visibility, and deep customization.
To support its rapid scaling and manufacturing goals, Astranis has successfully raised more than $1.2 billion in funding from prominent global investors, including Andreessen Horowitz, BlackRock, Fidelity, Franklin Templeton, and Snowpoint. The company currently employs a workforce of approximately 500 engineers, technicians, and business leaders. All design, manufacturing, assembly, and operational activities for its satellite fleet are centralized out of the company’s expansive 153,000-square-foot headquarters located in Northern California, United States.
