The technical work will be organised in 2 phases. In Phase 1 a new model for hot plume with particles will be developed to include the necessary physics such that the combustion process can be computed, the evolution of the alumina can be calculated in the engine and the subsequent impact of the alumina in terms of heat radiation to the upper stages can be quantified. Finally, in Phase 2 the new model will be used in combination with any CFD code provided by the bidder and validated with experimental data provided by ESA.

The objective of the Landmark ClearSpace-1 mission will be to demonstrate the complete value chain of active debris removal by removing an ESA-owned object (a VESPA upper part orbiting at an altitude of 500 km) by 2025.

Using the heritage of the existing space-x micro-cameras used in missions such as SMART-1, Exomars, the activity aims at developing a new generation of low energy and low cost cameras for future ESA missions. Thanks to on-going technological developments, the mass of scientific imaging systems (in particular for space exploration) was already drastically reduced during the past few years. However, progress in micro-electronics will also allow a significant reduction in power consumption.

CHEOPS mission was adopted by the SPC in February 2014 (ESA/SPC(2014)5) and is being implemented in partnership with Switzerland and several other Member States as defined in the CHEOPS Multi-Lateral Agreement (MLA, ESA/SPC(2014)4). The MLA includes in particular a Swiss contribution to the spacecraft system Assembly Integration and Testing (AIT), through activities to be provided by RUAG Schweiz AG (RSSZ) under the authority and responsibility of the CHEOPS spacecraft contractor.

The novel technology of Modelocked Semiconductor Lasers (MLSCL) is a promising candidate to be used in optical metrology systems for various space applications, e.g. in the context of optical interferometry or frequency and distance metrology as well as optical communications and data processing. Recent laboratory demonstrations of MLSCLs are capable of producing VIS / NIR ultrashort light pulses in the few picoseconds time regime at very high repetition rates in the MHz domain.

A number of studies have demonstrated the many advantages of miniature battery- powered timing sources: integrated in a portable user terminal, such sources allow for ultra-fast acquisition (e.g. for secured telecom with long spreading codes) and long coherent integration (e.g. for GNSS operation in interference or indoor environment). Similarly, it has been shown that such sources would significantly improve the sensitivity of some on-board EO instruments (e.g. radiometers, radio- occultation).

This study aimed to develop a framework for studying the effects of spacetime curvature on the propagation of quantum states of light, and to compare them with the propagation of classical light. When distributing entangled photon pairs through a gravitational potential, the effect of spacetime curvature on the properties of quantum states can become significant. This could be relevant for plans to use satellites for global quantum key distribution.

The project aimed to design an optical instrument based on Compressive Sensing (CS) for a space applications. Conventional sampling or compression methodologies follow the Shannon-Nyquist theorem, which states that if a signal frequency band or spectrum is limited to a frequency B [Hz], the signal is completely determined by a sample-rate larger than 2xB samples per second. Compressive Sensing (CS) provides a fundamentally new approach to data acquisition or signal sampling.

Today, there is little knowledge on the attitude state of decommissioned objects.Observational means have improved in the past years, but are still limited regarding accurate estimate of motion vector orientations and magnitude.Yet, such knowledge is essential for the preparation of a removal mission, since attitude motions above a few degree per second will not allow to use classical robotic capture mechanisms anymore. Hence, the attitude state of the target is a significant criterion for the selection of removal techniques.
