As the realm of space exploration continues to progress, the need to ensure the secure and sustainable operation of spacecraft during end-of-life re-entry has become increasingly critical. To meet this challenge, aerospace engineers are employing specific methodologies and tools for meticulous analysis. Among these tools, the Debris Risk Assessment and Mitigation Analysis (DRAMA) has emerged...

Based on current projections of launch rates, the global threat of space debris reentering Earth's atmosphere, primarily caused by the use of highly durable spacecraft components, necessitates the adoption of multiple complementary mitigation strategies. To address this issue effectively, integrating a dedicated Design for Demise approach during the early stages of spacecraft design enables a...

The very dynamic nature of space flight activity, in combination with a progressive growth in space debris, requires associated space debris mitigation standards and practices to co-evolve. Similarly, there is a strong need for the development of tools to assess and verify compliance with those standards and derived requirements for specific satellite missions. The Debris Mitigation Facility...

Due to the multiplication of private actors in the space adventure, France has adopted in 2008 the French Space Operation Act (FSOA), which establish a national regime of authorization and supervision for space activities. Then, the Technical Regulations has clearly addressed the concepts of safety and sustainability of space activities, including the safety of people and property. Within this...

MICE (Mechanical Interface for Capture at End-of-Life) is a single-part passive interface designed for enabling the capture and de-orbiting of satellites at their End-of-Life or in premature malfunction by a Servicing Spacecraft in case the satellites cannot be deorbited by themselves.
MICE has been developed under several ESA contracts by a consortium led by GMV, in charge of system-level...

When simulating space debris during atmospheric entry, the thermal environment is often modelled using heat flux correlations, with the resultant thermal loads being averaged over simplified representations of spacecraft (complex compound shapes composed of geometric primitives). Although this procedure is computationally efficient, the application of averaged heat fluxes to such compound...

To limit the risk of cascading collisions, we will need active debris removal missions to retrieve satellites that die before they can be deorbited. It is well understood that sudden fatal failures can cause a dead satellite to tumble uncontrollably, but even properly decommissioned satellites may start tumbling spontaneously from solar radiation pressure torque buildup, making capture...

Fiber reinforced plastics (FRPs) have previously been considered demisable because of their organic nature and the fact that they would be able to burn at ground conditions. However, entry flight simulations revealed that this assumption was overly optimistic. Instead of quickly burning away, fiber reinforced composites typically behave similar to the materials used in ablative thermal...

One of the main challenges driving the complexity of the rendezvous and capture of a debris is its rotational state. In-orbit observations of defunct satellites do not show an ideal Gravity Gradient capture, but instead large angular rates letting the... -

With the number of LEO satellites also increases the need for a demisable tanks in case of an uncontrolled reentry. Simulations have shown that it is not enough to only melt the aluminum liner during the reentry if market relevant tank sizes of around 40L and 150bar operating pressure are considered. The composite of the vessel must degrade to a high extent so that an impact to ground does not...

Abstract
In the latest years ESA has taken a proactive role in the area of Active Debris Removal (ADR) by preparing the new generation of Earth Observation satellites for a potential removal as part of their End-of-Life management. In this respect, the six Copernicus Sentinel Expansion Missions have adopted the Design for Removal Interface Requirements Document produced by ESA and are...

After more than two decades years of experimental and numerical simulation of the demise of materials and components during the entry flight, our knowledge on the phenomena involved in this destructive process and correct modelling thereof is still quite limited. There are many unknowns regarding the behaviour of the various materials and material categories and huge uncertainties. It is...

Controlling the levels of space debris has become a greater focus of the industry given the volume of spacecraft expected to be launched in the foreseeable future. The re-entry of spacecraft into the Earth’s atmosphere can contain fragments which are able to survive the loads and heat experienced during re-entry into the atmosphere. These same fragments will also have a probability to cause...

This presentation is to present our current findings on how a circular economy can be extended to outer space. We take a look at other industries and identify the requirements of circular material flows in space. We then describe a case study for a typical spacecraft and outline a process to change from linear to circular perspective, and to servicing, reuse, and remanufacturing in space.
