Enduralock Validates OneLink™ Prototype in Zero-G Simulation

LENEXA, KS – Enduralock is pleased to announce the successful completion of form, fit, and function testing for its OneLink™ satellite docking connector in Arkisys’ 1G robotic ground test facility for ISAM. This recent validation marks a critical step forward for In-space Servicing, Assembly, and Manufacturing (ISAM) capabilities. By proving the hardware’s soft docking and self-alignment capabilities work in a simulated zero-gravity environment, the team has confirmed the reliability of the mechanical latching and alignment systems essential for future on-orbit operations.

During the test campaign, a prototype of the female half of Enduralock’s OneLink™ connector was mounted on an Arkisys Port prototype, while the male half was mounted on a robotic arm provided by Motiv Space Systems to simulate a zero-gravity environment on orbit. Dr. Harold Hess, CEO of Enduralock, noted that seeing the OneLink™ halves successfully self-align and soft dock gives the team high confidence in the design. The testing successfully validated OneLink’s™ ability to manage off-nominal approaches, compensating for both angular and radial misalignment to achieve a secure soft dock.

This technical success opens the door for Enduralock to be included on future Arkisys launches. The male half of OneLink™ is scheduled to launch onboard the first Arkisys Cutter satellite in early 2027. Subsequently, the female half will launch onboard the first Arkisys Port Module in mid-2028. Integrating OneLink™ onto these missions supports the vision of a reconfigurable, standardized interface that allows customers to integrate payloads quickly and securely.

Dave Barnhart, CEO of Arkisys, emphasized that the Arkisys Port is designed as a scalable business platform in orbit, one that depends on robust logistics and reliable connection standards to enable growth. “Arkisys is committed to building partnerships that deliver the key technologies required for the expanding in-space servicing, assembly, and manufacturing (ISAM) market,” Barnhart stated. “Physical, standardized connections are the backbone of a thriving orbital economy, enabling refueling, in-space assembly, and cargo movement between spacecraft to establish a sustainable manufacturing base in orbit.”

Dr. Hess added, “Our collaboration allows Enduralock to demonstrate that OneLink™ is the right standard for reliable, repeatable docking operations, an essential capability for the next phase of orbital infrastructure.”

Today’s satellites launch with fixed lifespans and limited mobility, but this partnership changes that paradigm. The OneLink™ connector provides a universal mechanical interface that supports power, data, and fluid transfer, creating a new foundation for in-space logistics, life extension, and commercial service networks that can dramatically reduce cost and risk while unlocking recurring revenue in orbit.

About Enduralock
Enduralock is developing essential hardware for In-Space Servicing, Assembly, and Manufacturing (ISAM). The company’s portfolio focuses on three core technologies: the OneLink™ docking connector, which enables refueling, upgrades, and in-space transportation; the OneCatch deployable capture mechanism designed to extend satellite life or remove debris; and the OneBuild robotic end effector that uses Enduralock’s unique fastening system for on-orbit autonomous assembly. Together, these systems provide a practical solution for maintaining and constructing assets in a sustainable orbital environment.
