SpinLaunch - ?

As of August 2025, focusing more on the Meridian Space satellite constellation.

SpinLaunch is an innovative new space technology company that has created an alternative method for putting 200 kilogram class satellites into low earth orbit. Unlike traditional fuel-based rockets, SpinLaunch uses a ground-based, electric powered kinetic launch system that delivers a substantially less expensive and environmentally sustainable approach to space access.

The SpinLaunch Orbital Launch System is a fundamentally new way to reach space. The velocity boost provided by the accelerator's electric drive results in a 4x reduction in the fuel required to reach orbit, a 10x reduction in cost, and the ability to launch multiple times per day.

12U MICRO SATELLITE BUS

The S-20 is a low-cost, mass manufactured satellite bus designed for rapid development and deployment of commercial constellations. It is the ideal size mix for a range of applications, including LEO constellations that provide services such as Automatic Dependent Surveillance-Broadcast (ADS-B), Internet of Things (IoT), Machine to Machine communications (M2M), Automated Identification Services (AIS) or Emergency communications platforms. The bus is also ideally suited for prototyping, technology development, and experimentation such as scientific research, space systems R&D, flight heritage qualification or Earth Observation (EO).

200 KG SATELLITE BUS

The S-200 is a low-cost, highly flexible satellite platform for Low Earth Orbit applications. The clean-sheet bus design provides high performance for a variety of payloads, such as telecommunications and global earth observation. The S-200 takes advantage of SpinLaunch's unique approach to producing mass manufactured, high-quality space components.

REACTION WHEEL

The RW-20 is a custom reaction wheel specifically designed for use in both the SpinLaunch mass accelerator, as well as traditional launch systems. An embedded motor controller allows the RW-20 to function as a single unit, or in the standard 4-unit pyramid alignment. The motor controller is designed to work directly with the SpinLaunch EPS. The RW-20 has been designed to support the S-20, to meet the high precision pointing needs of demanding payloads. The RW-20 is recommended for use in combination with SpinLaunch magnetorquers for the most effective attitude control system. ​
