Vast Space announced on May 19, 2026, that it plans to sell high-power satellite buses, expanding beyond its private space station program. The Long Beach, California-based company says the new line is intended for communications, Earth observation, national security and orbital data center missions.
Vast says a confidential customer has signed an agreement for four satellites, with an option to purchase up to 200 additional spacecraft. The company is targeting an initial launch of 10 satellites in late 2027. The additional spacecraft covered by the option are not firm orders.
Platform specifications and computing option
A satellite bus provides the systems that support a customer’s payload, including power, propulsion, navigation, pointing, thermal control and communications.
Vast’s stated specifications for its first offering include a 15 kW power class, dimensions of about 3 meters long and 4 meters tall, an unfueled mass of about 700 kilograms and capacity for at least 350 kilograms of payload.
The company says the initial platform is designed for five years of operation in low-Earth orbit. Its broader plans include missions in other orbits, including lunar orbit; those applications are planned capabilities rather than demonstrated performance of the initial bus.
Vast also plans to offer Nvidia’s Space-1 Vera Rubin Module as an option for AI inference and data processing in orbit. Nvidia’s product announcement listed the module for future availability without specifying a release date.
Technology shared with the Haven program
CEO Max Haot said much of the satellite bus technology—including batteries, flight computers, sensors, flight software, and guidance, navigation and control systems—had been developed in-house for the Haven-1 space station. Vast says that work provides the foundation for a new product line.
Some shared systems flew on Haven Demo, which launched on November 2, 2025. Vast says the demonstration spacecraft completed 49 test objectives during its three-month mission and performed a controlled deorbit in February 2026. The mission tested technologies including power, propulsion, avionics, communications and flight software.
The satellite line also requires further development. Haot said Vast was developing electric propulsion and deployable solar arrays in-house for the new platform.
The expansion comes before Haven-1’s first flight. Vast says the station has entered integration and is targeting readiness to launch in the first quarter of 2027, with environmental testing planned for 2026. That is a readiness target rather than a confirmed launch date.
Vast says its spacecraft manufacturing facilities, including clean-room capacity, can support both satellite and space station production. It is entering a satellite platform market that includes Rocket Lab, K2 Space, True Anomaly, Blue Canyon Technologies and Millennium Space Systems.
