Hermann Bondi was an applied mathematician of distinction who will be remembered by fellow scientists for his outstanding contributions to astronomy, cosmology and General Relativity, and particularly for his pioneering contributions to our understanding of gravitational waves, his foundational work on accretion, and as co–creator with Tommy Gold and Fred Hoyle of the steady state theory of cosmology. But Hermann had an equally important second career in scientific administration: advising the UK Government on the Thames Barrier, as Director General of the European Space Research Organisation (ESRO; now the European Space Agency (ESA)), as Chief Scientific Adviser to the UK Government on Defence and then on Energy, as Chairman of the Natural Environment Research Council (NERC), and finally as Master of Churchill College, Cambridge. He was knighted in 1973. He continued his research on gravitational radiation throughout his administrative career and published his 16th paper in the series on gravitational waves in 2004. Hermann will be remembered not only for his contributions to science and administration but also for his outstanding communication skills and as a charismatic, warm, and stimulating person.

For a long time, space policy was pursued outside the EU framework either by MS individually or through independent cooperation structures, such as the European Space Agency (ESA). The intergovernmental ESA Convention was signed in Paris on 30 May 1975 by Belgium, Denmark, France, Germany, Italy, the Netherlands, Spain, Sweden, and the UK and entered into force on 30 October 1980. While the EU’s involvement in space activities had been developing already since the 1980s, with the establishment of the Galileo and Copernicus space programmes at the turn of the millennium, these activities were only given a firm footing in the EU primary law by the ToL’s introduction of Article 189 TFEU.

AbstractThe discovery of binary pulsar PSR 1913+16 by Hulse & Taylor in 1974 established the existence of gravitational waves, for which the 1983 Nobel Prize was awarded. However, the measurement of astrophysical parameters from gravitational waves will open an entirely new spectrum for discovery and understanding of the Universe, not simply a new window in the electromagnetic spectrum like gamma ray telescopes in the 1970s. Two types of ground-based detectors, Advanced LIGO/Virgo and Pulsar Timing Arrays, are expected to directly detect gravitational waves in their respective frequency bands before the end of the decade. However, many of the most exciting sources are in the band from 0.1–100 mHz, accessible only from space due to seismic and gravity gradient noise on Earth. The European Space Agency (ESA) has chosen the 'Gravitational Universe' as the science theme for its L3 Cosmic Visions opportunity, planned for launch in 2034. NASA is planning to participate as a junior partner. Here we summarize progress toward realizing a gravitational wave observatory in space.

Abstract Hinode is Japan’s third solar mission following Hinotori (1981–1982) and Yohkoh (1991–2001): it was launched on 2006 September 22 and is in operation currently. Hinode carries three instruments: the Solar Optical Telescope, the X-Ray Telescope, and the EUV Imaging Spectrometer. These instruments were built under international collaboration with the National Aeronautics and Space Administration and the UK Science and Technology Facilities Council, and its operation has been contributed to by the European Space Agency and the Norwegian Space Center. After describing the satellite operations and giving a performance evaluation of the three instruments, reviews are presented on major scientific discoveries by Hinode in the first eleven years (one solar cycle long) of its operation. This review article concludes with future prospects for solar physics research based on the achievements of Hinode.

Harry Elliot, a pioneer of British space science and known worldwide for his work on cosmic rays, passed away in July 2009. Coming from a farming family in the Anglo-Scottish borders, he entered Manchester University at the outbreak of war. After service in the Coastal Command of the Royal Air Force, he returned to Manchester to work with Patrick Blackett on the origin of primary cosmic rays, a scientific pursuit he followed for the rest of his career. In 1954 he moved with Blackett to Imperial College. After playing an important part in the International Geophysical Year, the dawn of the space age gave him the opportunity to be the originator of one of the major British space research groups. Subsequently, through his long-standing service at high level in the UK Science Research Council, the European Space Research Organisation and the European Space Agency, he played an important part in steering the development of British astronomical facilities as well as the evolution of European space science.
