The Sun regularly releases considerable amounts of energy resulting in coronal mass ejections (CMEs) and accelerated particles, which can have a variety of adverse space weather effects at Earth and in the near-Earth environment. A useful means of tracking space weather activity is via solar radio bursts (SRBs) associated with CMEs and solar energetic particle events (SEPs); CME-driven shocks can be tracked via Type II SRBs, while energetic electrons escaping into the heliosphere can be tracked via Type III SRBs.

Space weather observations and the prediction of expected disturbances on ground- and space-based infrastructure are critical for the safety and evolution of our modern society. Space weather events, like solar storms, can have a significant impact on navigation, communication, power grids and other electrical conducting infrastructures. Therefore, space weather predictions are very important, but recently lack a reliable estimation of the geo-effectivity as well as detailed information for regions and systems potentially affected.

In this project the authors looked at event-based sensing and processing for space situational awareness (SSA). Many advantages exist with the new paradigm of neuromorphic engineering, the authors investigate whether event-based optical data is suitable for the task and if processing with Spiking Neural Networks (SNN) provides advantages in terms of efficiency and efficacy. With the implementation of a novel heterogeneous LIF SNN, authors claim to surpass the state of the art in event-based SSA with a 15% increase in accuracy.

In applications such as space traffic and disaster response management, there are growing public and private capabilities. Multiple different stakeholders can detect and identify events (space collision predictions, natural disaster definitions). Augmentation of events definitions lead to confusion for local authorities, operators or any users of these information for costly decisions. This project, Space DAO, sets the base infrastructure to agree on consensus mechanisms to reduce confusion and augment trust in key decision making information.

With the 'democratisation of space', and the proliferation of large non-geostationary orbit constellations, the pace at which human-made objects are being deployed into orbit demands urgent action in defining and supporting a global space traffic management plan.

The market for life‐extension services for GEO satellites is expected to remain healthy over the foreseeable future: over the last 20 years, an average of 22 new GEO satellites have been launched per year. In total, ClearSpace expects there will be 370 potential Client satellites that will reach their end of life due to the limited fuel they have remaining over the 2026‐2041 period. ClearSpace believes a strong market penetration rate is feasible, as more than 30% of all the potential satellites belong to just 7 satellite operators.

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:

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.

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.

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.
