D-Orbit to Guide MORPH, ESA's First In-Orbit Satellite Refueling Mission

The European Space Agency (ESA) has selected D-Orbit as the prime contractor for MORPH (Modular On-Orbit Refurbishment for Permanent Hardware), a pioneering mission aiming to demonstrate, for the first time in Europe, the in-orbit refueling of satellites. This significant announcement was made on March 24, 2026, during the SatShow 2026 in Washington D.C., where D-Orbit participated as part of the Italian Pavilion.

MORPH represents a crucial step towards a new paradigm for satellite utilization. Currently, satellites are designed with a finite operational life, functioning only until their fuel is depleted or their systems fail. When either of these conditions occurs, the satellite is typically replaced with a new one launched from Earth. This conventional approach, however, is not only costly but also contributes to the increasing number of objects in orbit, exacerbating the problem of space debris.

The core concept behind this mission is to fundamentally alter this approach. By employing in-orbit maintenance technologies such as repairs, upgrades, and refueling, satellites could continue to operate for significantly longer periods. This would consequently reduce the need for frequent new launches and allow for a more efficient utilization of existing space assets.

MORPH builds upon the groundwork already laid by D-Orbit with its RISE mission, which is scheduled for 2029. Compared to RISE, this new project aims to investigate and implement more advanced solutions, particularly in the realm of in-orbit refueling. Following a preliminary phase that has already been successfully completed, the program is now entering Phase A, during which the primary aspects of the mission will be meticulously defined.

Towards Reusable Satellites and a More Sustainable Space

During the eight months allocated for the Phase A study, D-Orbit, in collaboration with its consortium partners, will develop a comprehensive mission concept for demonstrating in-orbit refueling. This includes defining the system architecture, detailing the operational scenario, and identifying the necessary technologies required to perform these complex operations safely and effectively.

The project leverages the GEA platform, an innovative system specifically developed by D-Orbit for in-orbit servicing under contract with ESA. This versatile platform will be adapted with modular interfaces and robotic systems capable of interacting with other satellites, enabling critical operations such as fuel transfer or the replacement of components.

A significant focus of the study pertains to satellites in geostationary orbit (GEO), where many of the systems vital for everyday global communications and services reside. The ability to intervene on these satellites directly in space would allow them to remain operational for extended periods, thereby reducing the immediate necessity to launch new replacements.

MORPH aligns perfectly with ESA's overarching strategy to foster a more sustainable space environment. The mission's objective is to reduce the accumulation of space debris and optimize the utilization of resources already present in orbit.
