The Hipparcos satellite, developed and launched by the European Space Agency (ESA) in 1989, was the first space mission dedicated to astrometry - the accurate measurement of positions, distances, and proper motions of stars. Amongst the key achievements of its measurements are refining the cosmic distance scale, characterising the large-scale kinematic motions in the Solar neighbourhood, providing precise luminosities for stellar modelling, and confirming Einstein's prediction of the effect of gravity on starlight. This authoritative account of the Hipparcos contributions over the last decade is an outstanding reference for astronomers, astrophysicists and cosmologists. It reviews the applications of the data in different areas, describing the subject and the state-of-the-art before Hipparcos, and summarising all major contributions to the topic made by Hipparcos. It contains a detailed overview of the Hipparcos and Tycho Catalogues, their annexes and their updates. Each chapter ends with comprehensive references to relevant literature.

Our understanding of the Universe has come under increased scrutiny over the last 25 years. New instruments have opened fascinating perspectives for testing General Relativity, alternative theories of gravitation, as well as studying quantum mechanics and exploring the boundaries of quantum gravity. Violations of the principle laws of the currently underlying theories can give clues to aid the unification of the four physical forces, or lead the way for the discovery of new interactions and particles.
The aim of the Fundamental Physics Explorer (FPE) is to provide the means to test the the foundations of modern physics in a cost effective and efficient manner. The FPE programme could consist of up to three spacecrafts, each re-using a small platform, accessing space to take advantage of an almost constantly unperturbed environment, thus improving the precision of current measurements. More specifically, the FPE Technology Reference Study (TRS) aims to identify the key technologies required and the technical challenges associated with fundamental physics missions.
