Angle-based Correlation (AbC), refined astrometry on board a CubeSat, Experiment 156 on OPS-SAT

AbC is a compact on-board algorithm, initially intended for CubeSats, to measure the absolute direction of a distant beacon with optimised accuracy. The AbC environment anticipates a ground pipeline that has been used with OPS-SAT images to diagnose the ADCS. It has been shown that a ground-truth assessment of the satellite's orientation can be made which, with sufficient data, could allow precise re-alignment of multiple sensors. The ESA contract funded the implementation of the on-board algorithm in C++ and its pipeline in Python.

Power sail disruptive PV power array technology to enable economic viability of SPS

The goal of the Powersail project is to demonstrate the potential of amorphous silicon (a-Si) deposited on ultralight space-grade polyimide for solar power satellites (SPS). State of the art solutions are III-V compound semiconductor triple junction-based PV modules, which are 100 times too expensive and one order of magnitude too heavy to build a competitive SPS with terrestrial microwave energy collection infrastructure.

A Consumable-less Propulsion System Based on a Bare-Photovoltaic Tether

As proved in several missions, the Lorentz force acting on the electric current carried by a space electrodynamic tether (EDT) can be used to propel spacecraft without using propellant. State-of-the-art EDTs involve a bare tape for passive electron collection (anodic contact) and an active device, or a tether segment coated with a low-work-function material, for electron emission (cathodic contact).

Occultation astrometry for NEA study and risk mitigation

This project, renamed ACROSS (Asteroid Collaborative Research by Occultation Systematic Survey), aimed at considerably improving the predictability of stellar occultations by small and difficult targets such as the Near Earth Asteroids (NEAs). In particular, it focused on the binary asteroid 65803 Didymos, target of the DART (NASA) and Hera (ESA) missions, and other NEAs: either secondary targets of Hera, or NEAs whose orbit is accurate enough. Stellar occultations are an unbeatable approach to:

Lunar ISRU Energy Storage and Electricity Generation (LIESEG)

Humankind tested its capacity to survive on the Moon’s surface for short periods of time through the Apollo missions almost 50 years ago. Since then, robotic missions to the Moon have spent periods lasting several days and nights on the satellite. However, many technological challenges arise when planning a lunar (robotic and/or manned) mission that is fully operational during the night. Among these challenges, the need for a power supply system for both day and night remains open.

Study into Ultra-Wide-Band SAR Tomography over Dry, Rocky Terrains

In recent years, surface-penetrating radars have formed a part of several ESA missions in both monostatic and bi-static configurations. Such radars can be found, for instance, on board Mars Express where, using MARSIS, the Martian sub-surface is sensed, as well as on board Rosetta where CONSERT was used to probe the comet 67P/Churyumov-Gerasimenko.

Local sleep episodes during wakefulness and long term space travel

The aim of this study was to assess how space travel modifies local sleep episodes in wakefulness during a visuo-motor task and weather this is related to performance. To this end, specific EEG (electroencephalogram) data previously recorded on board the ISS during the Neurospat experiment (AO-2004, 118) were used.

Asteroid Impact Mission Advisory Study

In this report, we describe the advisory study for both the Asteroid Impact Monitoring (AIM) as a stand-alone European mission and for AIM with its second component, the US Double Asteroid Redirection Test (DART) mission under study at NASA by the John Hopkins University Applied Physics Laboratory.

AIM High-Frequency Radar Concept Design

This purpose of the study was to develop a high frequency radar to sound the first tens of metres of asteroid regolith and to achieve 3D tomography with metric resolution in order to
- Determine its structure and layering
- Identify geomorphological elements (rocks, boulders, etc.) embedded in the sub surface
- Map the spatial variation its texture
- Derive an estimate of dielectric permittivity of the sub-surface material

Land cover monitoring for water resources management in Angola

Water resources management has become a challenging problem worldwide, especially in developing countries. The lack of information on land cover monitoring has a huge impact on the water resources management, since it may hamper the collection, treatment and distribution of water for human consumption and agricultural development. To fulfil this demand, Earth Observation (EO) data has been used in African countries to map land cover of large and often inaccessible areas, providing useful information on qualitative and quantitative land cover changes.
