# Space Energy Initiative Proposes Modular Infrastructure Assembled in Orbit

![](https://i0.wp.com/newspaceeconomy.ca/wp-content/uploads/2026/11/aa6345cb-33d6-4a3a-8dc9-cc3225b88e2b.png?resize=696%2C464&ssl=1)

The Space Energy Initiative has proposed a British role in developing large-scale space infrastructure built from components that can be assembled, serviced, and upgraded in orbit. Its November 4, 2026, [white paper](https://spaceenergyinitiative.org.uk/wp-content/uploads/2026/11/LSSI-White-Paper-Final.pdf) describes two architectures: physically connected structures and groups of separate modules operating within a defined orbital area.

Connected structures include proposed solar-power platforms, large telescopes, computing facilities, and habitats. Clustered facilities could accommodate manufacturing, storage, or recycling activities. The distinction is physical: one architecture joins components into a structure; the other places separate assets near one another.

The initiative presents these architectures as complementary to satellite constellations. Its proposed applications emphasize activities involving large collecting areas, substantial power, industrial equipment, or inhabited space.

## **Building Beyond the Launch Fairing**

In-space assembly separates the dimensions of a completed structure from the dimensions of the rocket carrying its individual parts. A payload fairing encloses and protects spacecraft during launch. Components can travel inside separate fairings and later connect in orbit.

[NASA’s description of assembly](https://www.nasa.gov/isam/) defines the activity as bringing two or more parts together in space to create a functional structure. This differs from manufacturing, which produces or transforms material, and servicing, which maintains or changes an existing spacecraft.

Those activities can support the same installation. Assembly establishes the structure; servicing replaces or upgrades equipment; manufacturing can produce components or other goods. New Space Economy’s explanation of [in-orbit assembly and maintenance](https://newspaceeconomy.ca/2025/12/12/in-orbit-servicing-assembly-and-maintenance-the-future-of-sustainable-space-operations/) describes the relationship between modular construction and continued operation.

The International Space Station provides an established example of joining separately launched elements. The new proposal applies the broader principle to additional infrastructure categories, including energy and industrial services.

## **European Research on Connections and Robotics**

[ESA](https://www.esa.int/)’s [LATTICE research campaign](https://www.esa.int/articles/advancing-research-and-development-of-large-space-structures) supplies concrete examples of work on the mechanisms used to assemble and maintain large structures. In February 2026, [ESA](https://www.esa.int/) reported 12 activities selected from 69 submissions: five studies, four early technology developments, and three co-sponsored research activities.

At the University of Trieste, the REALISE2 project is investigating modular components with rails that allow a robot to move along the structure. The proposed components incorporate sensors and electrical distribution, with connectors carrying structural loads, power, and data.

Cranfield University’s I-TRAILS work examines stackable tiles with integrated rails and interfaces. The tiles are intended to carry functional elements such as mirrors or solar panels. A separate Munich University of Applied Sciences study investigates adhesives cured by ultraviolet light for bonding, maintenance, and repair.

These projects address specific operations within an assembled structure: moving a robot, connecting components, distributing electricity, and repairing material.

## **Proposed Demonstration Milestones**

The Space Energy Initiative’s [published proposal](https://spaceenergyinitiative.org.uk/white-paper-large-scale-space-infrastructure/) sets out an in-space assembly demonstration within three years and a megawatt-class orbital pilot with a British anchor role within five years. It also proposes an initial commercial service enabled by large-scale infrastructure.

Published in 2026, those intervals correspond approximately to 2029 and 2031. They are proposed milestones in the initiative’s policy framework. The underlying architecture centers on separately delivered modules that become operational infrastructure through assembly and continued servicing in orbit.
