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.

GreenSat

Due to the harsh nature of outer space, stringent requirements and performances are required from space systems. Thanks to evolving environmental awareness and the building up of a knowledge base at ESA, we are becoming more wary of the environmental impact of space activities on Earth. Through the GreenSat project, ESA wants to evolve from the assessment to reduction of environmental impact through redesigning an existing satellite mission. The project allows ESA to check the feasibility of implementing ecodesign in the development of space missions.

Numerical Simulations for Spacecraft Catastrophic Disruption Analysis

At present, the largest part of the catalogued space debris population consists of fragments originating from accidental explosions of spacecraft and upper stages, but it is expected that hypervelocity collisions involving large objects could become the primary source of new debris in the mid-term future. In this context, understanding the physical processes involved in spacecraft collisions is crucial, because these big impacts are one of the key drivers of the long-term evolution of the amount of space debris.

REACH into LCA – Integration of REACH and CRMs into the Life Cycle Assessment framework

For the REACH assessment, the proposed method relies on both ESA’s existing Life Cycle Assessment (LCA) framework and the Materials & Processes Technology Board (MPTB) database. Then, the method was structured through three steps:

  • Firstly, a commonality was found between the LCA and MPTB databases: ECSS classes, which help define small groups of materials defined as 'clusters', are used to 'bridge the gap' in terms of level of precision between the LCA model of a space system and the MPTB database;

Magnetic Field Perturbations by Thermo-Electric Effects

Moving charges produce magnetic fields. Since thermal transients produce an electric current, thermal transients produce magnetic fields. It has been shown that the generation of these magnetic fields in the vicinity of sensitive instruments leads to a degradation of recorded data.

Getting closer to a theoretical solution and to an effective mitigation technique will help magnetic missions in ESA’s Science programme, Earth Observation programme and, in fact, all missions that employ magnetic-sensitive sensors.
