Development of EO indicators for the dynamic destrification in the Southern Africa

The objective of the study was twofold: i) to analyse the new dynamics of desertification in Southern African region (southern Mozambique, southern Zimbabwe and Northern South Africa) through main achievements of the DesertWatch-Extension; ii) to propose new methods for integration of EO data with different spatial and spectral resolutions, namely the new ESA Proba-V mission, and new field data, in particular, the map of risks on natural disasters in Mozambique.

Disposal strategies analysis for MEO orbits

The Medium Earth Orbit (MEO) region, home of the operational Global Navigation Satellite Systems (GNSS) GPS and Glonass, is becoming more and more exploited with the advent of the European Galileo and the Chinese Beidou constellations, both in their build-up phase. The sensitive applications of the navigation satellites and the absence of any natural sink mechanism, such as the atmospheric drag, call for a careful debris prevention policy able to preserve the MEO environment, avoiding in the future the problems now already faced by the LEO and the Geostationary Orbit (GEO) environments.

Detection of microparticle impacts on spacecraft via their plasma effects

Microparticles are one of the most unknown components of the space environment. Their observation and investigation is complicated by their small size and their high velocity. When impacting on a spacecraft surface, a plasma cloud is generated by shock wave and surface ionization processes. This transient cloud of vaporized and ionized particle and surface material, referred to as impact plasma, rapidly expands to the meter scale within microseconds, thereby interacting with spacecraft surface components.

Concept Definition and Demonstration of RAMS In-Orbit Data Utilisation

RAMS and risk assessments performed in the course of the system design, verification and operation of space systems rely on the availability of realistic input data. This input data is coming mainly from three different sources:
- MIL-HDBK-217F, Notice 2 for EEE components
- manufacturer supplied information (e.g. pyrovalves, reaction wheels)
- expert judgement based on experience and on the adaptation of data from space and non-space applications.

Interplanetary Micrometeoroid Environment for eXploration (IMEX, NEMS)

The approach of the ‘Interplanetary Meteoroid Environment for eXploration’ (IMEX) project is to build a model of meteoroid streams throughout the inner solar system. Our motivation for this model is the impact hazard to spacecraft. An understanding of the interplanetary environment, including the dust environment, is crucial for the planning of spacecraft missions in the inner solar system. Particles striking a spacecraft with high velocities can cause damage leading to the impairment or even failure of the spacecraft or its subsystems.

Fragmentation consequence analysis for LEO and GEO orbits DEBRIS

The simulations of the long term evolution of the space debris population, under realistic assumptions, show how the driving factor in the future environment will be mostly the breakup of large spacecraft and rocket bodies in LEO.

3-D Fire Radiative Power Modelling Approach

Biomass burning is a key Earth system process, a major element of the terrestrial carbon cycle and a globally highly significant source of certain atmospheric trace gases and (primarily fine mode) aerosols. Natural and anthropogenic biomass burning occurs on all continents except Antarctica, with an estimated average of 3.5 - 4.5 million km2 of vegetation burnt in global wildfires each year (though this does not include the very large numbers of "small" agricultural fires that are difficult to map using current coarse spatial resolution remote sensing datasets).

Interplanetary and Planetary Radiation Model for Human Spaceflight (IPRAM)

Gaps in existing radiation environment and effects standards adversely affect human spaceflight developments. The most important drivers in the domain of interplanetary and planetary radiation environments were investigated, identifying appropriate data sources and modelling methods to address the needs of future interplanetary manned mission design and operation.

Dusty Plasma Environments: Near-Surface Characterisation and Modelling

The NEMS – Near-Earth Exploration Minimum System internal ESA study, conducted at ESA's Concurrent Design Facility (CDF) between March and April 2011 aimed at investigating and reporting on the main trade-offs, system drivers and critical risk areas associated with even the most basic human exploration beyond Earth-Moon system. The (purely theoretical) mission scenario addressed the transfer a crew of 3 astronauts from the Earth to an accessible Near-Earth Asteroid (NEA) and their safe return to Earth before 2030. Dust contamination was identified as a major concern.
