In the frame of the ESA campaign “System Studies for the Circular Economy in Space”, Thales Alenia Space proposed to develop its ideas exploring the ways to enable Design For Circularity initiative focusing on the definition of a mission design and concept of operations of a Recycling Space Plant involving a solar furnace for materials melting. However, beyond the scope of this particular ESA initiative, Thales Alenia Space has been leading many external and internal activities on the way to define and develop a circular space economy.

The activity plans the following tasks:
 
Development, Integration and Validation of:
  • a Receive Telescope with a 80cm aperture mounted on a very precise Mount with arcsecond pointing and tracking accuracy
  • a Transmit Laser Package (precise pulsed source capable to operate at 532nm and 1064nm)
  • a time-gated photon-counting Detection Package (filters and detectors sensitive at 532nm and 1064nm)
  • a precise Control, Timing, Calibration and Processing System as the central "heart" of the LRS

Uncontrolled spacecraft re-entry requires the satellite to sufficiently demise in order to meet the casualty risk requirement. Heat generated during re-entry is not adequate to sufficiently demise some spacecraft equipment.
- Equipment (e.g. Large mechanisms, magnetorques, optical equipment) is hard to demise without big design changes as the functionality requires using metals with high melting temperatures.
- Earlier break-up of the interface of equipment to the structure, harness and pipework is beneficial for demisability.

This de-risk activity has successfully demonstrated that the use of the component level length scales over compound length scales in the calculation of heating rates can lead to a significant over-prediction in component temperatures.

Project HyperClass aimed at accelerating the technology to process spectra received from single pixel images of space objects and:

i) extract the material composition of the object,

ii) classify the object according to a set of predefined features,

iii) estimate the attitude motion from the spectral lightcurve.

Environment prediction models (like MASTER) are by no means static and require continuous improvements to keep the pace with an ever-changing highly dynamic space debris environment. New types of measurements (as, e.g., from potential in-situ sensors), newly discovered debris sources (as the release of MLI foils), and additional severe debris generating events (like the Chinese ASAT test of January 2007 and the Iridium-33/Cosmos-2251 collision in 2009) need to be reflected.

All missions in Earth-bound orbits rely on space debris and meteoroid flux models. These models are used to assess the mission risk and design shielding concepts (for manned modules). The flux predictions have been found to have a remarkable sizing effect. Collision break-ups are the major source of debris >1mm and are poorly understood. This needs to be improved significantly.
On Agency level, collision break-up modelling is decisive to define the Agency's position towards international agreements on space debris mitigation. Current models will be misleading.
