We design and manufacture laser retroreflector arrays in-house for Haven-1. Each array has three corner-cube retroreflectors mounted to an aluminum hub that reflect light back to visiting spacecraft, providing range and orientation during rendezvous and docking.

An intricate tubing system, consisting of more than 300 assemblies, will move oxygen, water, coolant, and propellant throughout Haven-1. Each one is designed, bent, welded, inspected, and tested, then installed on the flight vehicle at our Long Beach headquarters.

We design, build, and qualify Haven-1's cold plates in-house. Waste heat conducts from avionics devices into the plate, transfers to a pumped fluid loop, and the external radiator rejects it to space. These same thermal control systems will be scaled to Vast Satellite and future stations.

Our space stations and satellites use fluid systems to transport oxygen, water, coolant, and fuel. We manufacture, test, and integrate these systems in-house with the speed, precision, and scale required to build next-generation space infrastructure, starting with Haven-1.
