Nexus Space Systems

Payment infrastructure
for the orbital economy.

NIG is a universal docking interface that moves power, data and fluid between spacecraft — and meters and settles every transfer. The connector is the standard; the settlement network is the company.

The interface

One interface. Everything that flows between two spacecraft.

An androgynous coupling with a radiation-tolerant controller on board — it powers up, moves the payload, and records a trusted account of exactly what was exchanged.

PWR

Power — up to 40 kW

Three independent lines, sequenced on connection.

DAT

Data — up to 300 Gbit/s

High-bandwidth optical link over fiber.

FLD

Thermal-fluid provisions

Integrated channel for coolant and refuelling.

MCU

Metering & settlement

Every transfer is measured and settled at the interface — a record of exactly what was exchanged.

Nexus Interface Gateway — power, data and thermal ports
The gap

Space is becoming modular. Value has no way to move.

Independently-owned stations, servicing vehicles, tugs and depots now have to couple and share resources across operators. Today there is no shared standard to connect them, and no settlement layer to clear what they exchange. NIG is built to be both.

How a transfer settles

Six steps, autonomously, at the point of connection.

01

Identify

The interface reads the counterpart's hardware ID over a contactless channel.

→
02

Authorize

Coupling is released only for a counterpart cleared against the onboard list.

→
03

Transfer

Power, data and fluid channels are sequenced and opened.

04

Meter

Quantities on every channel are measured in real time.

→
05

Record

A trusted, tamper-resistant record of the transfer is created.

→
06

Settle

The record clears on the ground: the platform is paid, the consumer is billed.

OUR GOAL

An open standard

We are building toward an open standard for docking and resource exchange across operators.

Get involved

Let’s build the standard for the orbital economy — together.

The rails for the space economy are being laid now. Whether you invest, partner, or build, there is a place for you in what comes next.

Investors

We’re raising to build it.
