Space is essential for extending our knowledge and understanding of our physical environment.

Four grand science themes were set by the ESA High-level Science Advisory Committee (HISPAC) to address the overarching science questions in ESA programmes:

Terrestrial and Cosmic ClimateUnderstanding GravityLife in the UniverseCosmic Radiation and Magnetism

Andromeda Galaxy seen by ESA's Herschel

These themes underline the importance of space for understanding Earth and for bringing a future in our daily life. The quest for knowledge through missions based on scientific and research excellence drives technological progress, which in turn allows the development of space applications and lays the foundations for the outstanding competitiveness of European industry.

Europe leads in the quest for the origin of the Universe and for the understanding of our planet and of the behaviour of life and materials in weightlessness conditions, with experiments carried out onboard the International Space Station (ISS).

Pushing knowledge further is a top priority for Europe, even rendered indispensable in light of Europe’s innovation and knowledge policy goals for 2020, while requiring novel partnership approaches at European and international level to curtail the consequences of the global economic crisis.

Space can also make a difference through a leading effort in human spaceflight, which is a vector for international peace and cooperation, and in exploration in the wake of ISS full assembly. In addition, efforts for clean, ethical, responsible and sustainable space activities will be foremost: ESA must indeed take leadership by becoming a model 21st century space agency.
