Investigation of Active Detumbling Solutions for Debris Removal

The main objective of this study 'DETUMBLING – Investigation of Active Detumbling Solutions for Debris Removal' was to propose and investigate a contact-based de-tumbling strategy using a robotic arm. Realistic models were developed for the chaser with robotic-arm, target and composite systems. Specific GNC strategies were developed for the different phases of the mission: robotic-arm deployment synchronisation with the target de-tumbling the composite.

Demisability assessment of Optical payloads

Spacecraft and their payloads are required to meet a casualty risk threshold for uncontrolled re-entries. The requirements demand that consideration be paid to the whole spacecraft and payload in order to achieve an optimised mission that is not penalised, where possible, by the cost of performing a controlled entry. The demisability of the spacecraft bus has received significant attention in recent years, the demisability of payloads has received less focus.

Impact Risk in LEO as a result of the Increase of Nano and Micro-Satellites

Low Earth orbit (LEO) is experiencing a renaissance thanks to increasing commercialisation of space. The opportunities provided by small satellites are enabling diminutive companies and startups, in particular, to make a significant impact on the space economy. Small satellites have played a vital role in this revolution and they have a unique ability to bring around new products and services at short timescales and for relatively low-cost.

Design for Removal: How to design S/C to support active debris removal if uncontrolled

The population of non-operational objects in the space environment is raising, increasing concern about the safety of operations for current and future space activities. In this respect, space agencies and in particular ESA with its ESA/ADMIN/IPOL (2014) have established policies to mitigate space debris creation. Please refer to the compendium of space debris mitigation standards adopted by states and international organizations, [RD.5], for additional information. This basically implies that satellites in LEO and GEO shall perform an End Of Life (EOL) disposal with a reliability of 90%.

Design for Removal: How to design S/C to support active debris removal if uncontrolled

In the future, satellites will have to demonstrate compliance with debris mitigation requirements, covering re-entry or parking graveyard orbits and passivation. Nevertheless, during the mission, a failure could occur without any possibility to manoeuvre the satellite and achieving its compliance to the Space Debris Mitigation requirements. Therefore to anticipate the need to use ADR for deorbiting (or reorbiting) the satellite, it is interesting to evaluate the implication of adapting the satellites and launcher upper stage to support a future ADR mission.
