ESA's Concurrent Design Facility (CDF) has completed a short study of a Cosmic Microwave Background Polarisation mission (CMB Polarisation) to support the European and Japanese science community in defining a collaborative mission studying the Polarisation of the Cosmic Microwave Background for calls for Cosmic Vision Medium-sized mission.

Further details can be found in the CDF presentation linked below and from the image to the right.

The spectral reflectivity of asteroid surfaces over the wavelength range of 0.3 to 1.1 micron can be used to classify these objects into several broad groups with similar spectral characteristics. The three most recently developed taxonomies group the asteroids into 9, 11, or 14 different clases, depending on the technique used to perform the analysis. The distribution of the taxonomic classes shows that darker and redder objects become more dominant at larger heliocentric distances, while the rare asteroid types are found more frequently among the small objects of the planet-crossing population.

This Cross-Scale summary report provides a summary of the system design study carried out by industry (Deimos Space S.L. as prime, Thales Alenia Space and ONERA as sub-contractors) under ESA contract between May 2006 and June 2007. The first phase of the system design study consisted of a mission architecture trade. Key trades on the mission architecture included orbits, number of spacecraft, payload suites, deployment strategy, and orbit optimization. The second phase consisted of an assessment of the spacecraft design, ground segment requirements and programmatics.
