Space Debris Deflection by Space-Based Laser

The study takes place in the context of the space environment remediation. Tackling the issue of space debris is becoming more and more critical as it becomes more dangerous for existing and future space missions. Solutions must be found to ensure the security of space missions security and a clean space environment. Laser pressure solutions are considered promising as they only using momentum transfer to perform debris manoeuvres to avoid collisions. This means that no additional debris is generated using this technique.

Preliminary design of on-orbit manufacturing of large antenna reflectors

This study aims to carry out the conceptual design of a large-parabolic-antenna reflector that is manufactured and assembled on-orbit.

Through its Clean Space initiative, ESA has been devoting an increasing amount of attention to the environmental impact of its activities, including its own operations as well as operations performed by European industry in the frame of ESA programmes. In its Technology Strategy, ESA identified 'Inverting Europe’s contribution to space debris by 2030' as one of the four technology development targets.

Hera Investigation Team (HIT) analyses

We have continued our shock physics code calculation studies of DART-like impact events. This includes comparisons of iSALE and SPH code calculations, using a range of strength and structural properties. The effect of porosity was studied in detail by applying different crushcurves, representing materials with varying crushing strength. The crushcurve was found to have a large influence on the outcome, in particular the ejecta properties and momentum transfer.

Feasibility study of Active Debris Mitigation for Mega Constellations

The Thales Alenia Space study team completed a 13 month contract to study the feasibility of Active Debris Removal within mega-constellations. Within the Clean Space initiative, ESA searches for proactive answers to the environmental challenges which are faced both on Earth and in space. The Inter-Agency Space Debris Coordination Committee (IADC) has already highlighted the important topic of mega-constellations, which represent a step change in the future space environment due to the proliferation of small satellites.
