It’s time to get serious about dynamic space operations

Space is crowded, contested, and unpredictable. Competitors and adversaries are ready to act when systems fail or conditions shift. In a dynamic domain, taking months (or years) to respond isn’t an option. It’s a liability.

Introducing

Nexus

Multi-Mission Robotic Spacecraft

NEXUS can maneuver, transfer between orbits, dock with other satellites, and perform robotic servicing. With NEXUS, you control your environment – not the other way around.
[TRL-6]

Robotics

NEXUS features our patented Split Stewart Platform, a robotic arm system designed specifically for space operations. Lighter and stiffer than standard robotic arms, the system allows NEXUS to grapple a wide range of structures, including satellites that were not originally designed for docking.
[TRL-9]

Rendezvous and Proximity Operations (RPO)

NEXUS features a full suite of sensors and optics that make it capable of both inertial guidance, navigation, and control (including orbital transfers) and relative GNC (so the spacecraft can rendezvous and dock with other satellites).
[TRL-5-9]

High Power Spacecraft Bus

Power & Propulsion: NEXUS features large solar arrays that collapse into a small form factor for ease of launch. Using custom avionics, these arrays deliver enough delta-V to propel NEXUS from Low Earth Orbit to the moon and back without refueling.

Hardware
payloads

NEXUS delivers hardware upgrades on mission relevant timelines.
With two payload bays, NEXUS can transport and install mission hardware. Instead of being trapped by 10+ year design cycles, now you can proactively upgrade unprepared satellites with new capabilities on-orbit.

Validate early and often to de-risk missions

We don’t rely on software simulation alone to validate mission readiness. Katalyst tests the full system stack—sensors, software, actuators, propulsion, and robotics—at our state-of-the-art testbed, designed specifically to validate our robotic spacecraft.
