About the European Space Astronomy Centre

ESAC, the European Space Astronomy Centre, is the ‘home’ of ESA’s space-telescope and planetary missions, the place from where science operations are conducted, and where all of the scientific data produced are archived and made accessible to the world.

ESAC has been chosen as the site for the Science Operations Centres (SOCs) of ESA Science missions for both astronomy and the Solar System. This means ESAC is rapidly evolving into a scientific hot-spot, a meeting point for top-level international space scientists working in different, but closely-related areas.

The archives for all of ESA’s astronomy and Solar System missions are kept at ESAC so researchers have a single ‘entry point’ for accessing the wealth of scientific data. Data from the ISO, XMM-Newton, Integral, Herschel, Planck and SOHO missions and from the interplanetary spacecraft Mars Express, SMART-1 (the Moon), Rosetta (Comet 67P/Churyumov-Gerasimenko), Huygens (Titan), Venus Express and Giotto (Comet Halley) are already available in ESAC’s state-of-the-art archival system, and are regularly consulted and retrieved by more than 3000 registered users.

ESA’s 35m diameter deep-space antenna for Europe is located in Cebreros (Avila) and supports the activities of ESAC by gathering data from distant missions to Mercury, Venus, Mars and beyond.

ESAC is also involved in Earth Observation activities. ESAC hosts the Payload Operations and Data Processing Ground Segment of the ESA’s Soil Moisture and Ocean Salinity (SMOS), second Earth Explorer satellite. Launched in November 2009, SMOS is designed to observe soil moisture over Earth’s land surfaces and salinity in its oceans, which are exactly the kinds of data urgently needed by experts studying the global climate system, and also feeds data in near real time to improve mid term weather forecast. ESAC takes care of the payload programming for SMOS, receives all the scientific data transmitted to ground, and generates and disseminates the final products to the community.

ESAC hosts the team for the new European Space Situational Awareness (SSA) Preparatory Programme. The SSA initiative will provide Europe and its citizens with complete and accurate information on objects orbiting Earth, on the space environment and on threats coming from space.
