Simplified models for aerothermodynamics analysis of space craft components: "design for demise"

Thousands of man-made objects are currently in orbit around the Earth. These range from active satellites to flecks of paint, via spent rocket stages and fragments of satellite debris. Due to the drag of the very thin high altitude atmosphere, these objects have slowly decaying orbits, and will eventually re-enter the Earth's thicker, lower atmosphere. Most will be destroyed on entry due to the aerothermal heating experienced at hypersonic velocities at altitudes between 40 and 80km. However, some objects reach the ground.

FLEX/SENTINEL-3 TANDEM MISSION PHOTOSYNTHESIS STUDY

Chlorophyll fluorescence (CF) is a natural spectral emission resulting from the interaction of plant chlorophyll pigment with visible light (typically 400‐700 nm). In photosynthesizing tissues, red and far‐red light can be emitted from any chlorophyll‐containing plant tissues which are exposed to light: primarily foliage, but also green stems, green exposed roots, floral structures, many fruits, and green seeds.

Dusty Plasma Environments: Near-Surface Characterization and Modelling

The main goals of the DPEM project was [RD1] "to set the foundations for the development of a comprehensive suite of near surface dusty plasma environment models applicable in particular (but not only) to airless bodies of interest for future exploration missions such as asteroids, the Moon, Phobos and Deimos, etc … These models shall allow the definition of charged dust environment specifications to assess the effects of dusty plasmas on near surface or surface exploration units (spacecraft, payload, lander, astronaut) in a surface-spacecraft-dust environment system."

Environmental impact assessment analysis

Public awareness of the urgent need for mitigating the environmental impacts of human activities is ever growing. This results in a more and more stringent public environmental legislation and an increasing public pressure. In this context, the European Space Agency (ESA), as a public sector intergovernmental organisation, wants to put the environmental concern as a priority in all its activities, as expressed in its Framework Policy on Sustainable Development.
