Exploring the Use of Molecular Dynamics Simulations for High-Performance Space Debris Collision Modelling

For long-term studies, numerical simulations are at the center of predicting the space debris environment of the upcoming decades. In the scope of the study, the authors present the architecture and proof-of-concept results for a numerical simulation capable of modeling the long-term debris evolution over decades with a deterministic conjunction tracking model in contrast to typically employed Monte Carlo methods. For the simulation, an efficient propagator in modern C++ accounting for Earth’s gravitational anomalies, solar radiation pressure, and atmospheric drag was developed.

An End of Life Strategy for Solar Power Satellites

Space Based Solar Power concepts promise the generation of large amounts of renewable power by launching vast Solar Power Satellites (SPS) into space and beaming the power back to rectennas on Earth. Due to diffraction physics, large scale arrays delivering 2GW of power to the ground will be on the order of a kilometre in length and have masses between 2,000 and 10,000 tonnes. As of January 2020, the amount of debris orbiting the Earth exceeded 8,000 metric tonnes.

Forecasting Space Weather in the Arctic Region (FORSWAR)

The main objective of this activity was to develop and demonstrate new techniques which are expected to improve the current state-of-the-art Space Weather forecasting techniques and products related to Space Weather effects for Positioning, Navigation and Timing (PNT) systems in the Arctic, with particular attention to the Greenland area. For this purpose, the activity investigated and tested innovative methods for monitoring and predicting Space Weather impacts on PNT in interested area.

Bio-inspired Solutions for Space Debris Removal

The BIOINSPACED project was initiated to find bio-inspired solutions for space debris removal because the identification, orbital alignment, capture and removal of uncooperative bodies in space is incredibly complex and no fully functioning method is available to date. Biology and its evolved mechanisms often provide specialized concepts that show great transferability to technical systems.

Space Weather Impact on Arctic Navigation (SWAN)

The objective of the Space Weather impact on Arctic Navigation (SWAN) project has been to
develop and demonstrate new techniques, which are expected to improve on the current
state-of-the-art space weather forecasting techniques and products related to space weather
effects for Positioning, Navigation and Timing (PNT) systems in the Arctic, with particular
attention to the Greenland area.

Inflatable Systems for Aerocapture and Aerobraking

This work has primarily focused on establishing scenarios where inflatable devices could be the most useful. Given that these missions rely on aerodynamic drag that results in (potentially significant) heating, the authors have sought to find solutions to minimize heat fluxes acting on the device surface, and especially keeping it within the limits of flexible/foldable TPS materials for the aerocapture scenario.

Analysis of space debris recycling potential to supply raw materials for construction on the Moon

As on Earth, space debris should not only be seen as a threat. Instead, the value of waste as a recycled good should be understood. On Earth, this potential is already fully recognised. The German recycling industry alone generates more revenue than the entire European space industry. Nevertheless, this treasure was never lifted in space.

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.

Fast development of kinetic impactor for short-warning asteroid deflection

The study demonstrates that in an emergency situation, with only a very short warning time, the launch of a fast asteroid kinetic deflection mission is feasible (targeting launch-readiness in six months!), given that certain identified pre-requisites have been prepared well in advance. The capabilities and requirements of 'hijacking' and modifying a commercial spacecraft platform in order to perform asteroid kinetic deflection in the shortest possible time were consequently assessed.
