Project Kuiper Demonstrates Controlled Satellite Maneuvering with Electric Propulsion System

Project Kuiper has achieved a significant milestone by demonstrating controlled satellite maneuvering in space using the electric propulsion system on its prototype satellites. The custom Hall-effect thruster, designed and built in-house by the Project Kuiper team, has provided critical on-orbit data to validate the satellite design. The test firings have consistently met the design requirements, proving the performance and capacity of the propulsion system.

This achievement is crucial for Amazon and the wider space community, as it advocates for a safer and more sustainable orbital environment. The propulsion system’s capabilities include raising satellites to their designated orbits after launch, maintaining their position, avoiding space debris and other spacecraft, and actively deorbiting them at the end of their missions. Amazon emphasizes that effective maneuvering capabilities and sharing information about spacecraft movements should be a requirement for satellites above 249 miles.

Rajeev Badyal, Project Kuiper’s vice president of technology, affirms that space safety and sustainability have been fundamental to Project Kuiper since its inception. The successful use of the custom thrusters for safe maneuvering in space is a testament to Kuiper’s innovation. The positive results further strengthen their confidence in deploying and operating their satellite constellation.

Project Kuiper’s prototype satellites entered low Earth orbit on October 6, 2023. The Kuiper System is designed to operate between approximately 367 miles and 391 miles above Earth, offering improved connectivity services and enabling a safer deorbit at the end of each mission. The custom-built electric propulsion system helps counteract the effects of Earth’s gravity, allowing the satellites to operate within 5.6 miles of their assigned altitude.

In addition to its effectiveness, the propulsion system is designed to be highly efficient in propellant usage, extending the lifespan of each satellite while prioritizing safety and sustainability.

Project Kuiper continues to focus on its commitment to space safety and sustainability. For more information on the propulsion system design and the broader initiatives of Project Kuiper, please visit their website.
