SMOS_11-02-08.jpg
spacer.gifThree-quarters of the globe is covered in water and its influence is felt everywhere. Its not only oceans, rivers and lakes that affect the climate but water in all its forms, such as soil moisture and its evaporation. SMOS, ESAs water mission, will provide a uniform dataset for understanding better the water cycle, thus helping to forecast climate change and predict extreme weather conditions. Circulating at a low orbit of around 750 km above the Earth, SMOS will be the first satellite to provide us with a global picture of ocean salinity levels. Understanding the salinity and temperature of the seas will help to predict more easily the zones where hurricanes intensify as they pass over the ocean. Salinity in the oceans has a big impact on ocean circulation, which plays a key role in driving the global climate. The SMOS satellite will be launched into space in 2008 atop the Russian launcher Rockot.

ROSETTA_17-01-08_S.jpg
spacer.gifBefore each manoeuvre, the mission control team at ESA's Space Operations Centre simulates all aspects of the upcoming operation and practices identifying and solving problems that could arise. The multinational team must work as one to react immediately and effectively. Once at its target comet in 2014, Rosettas lander, Philae, will touch down and study the comets surface composition and drill into the icy nucleus to collect and analyse samples, including complex organic material that may have contributed to the formation of life on Earth.

spacer.gifThe European Space Astronomy Centre (ESAC) receives data from deep-space ground stations worldwide. The huge volume of data that comes back to Earth from space has to be calibrated and translated into a format that can be exploited by scientists.

radio_astronomy_S.jpg
spacer.gifRadio telescopes must be very large in size to achieve the same resolution as optical telescopes. The only way to do this is by coupling two or more of them, the further apart the better, and to analyse their combined signals. An interferometer is a system which can avoid increased expenses due to the large size of the receiver. It consists of two or more elements of large antennae. By connecting them in a special fashion, it is possible to artificially create a larger telescope. The European hub for what is called Very Long Baseline Interferometry (VLBI) is situated in Dwingeloo in the Netherlands, at the Joint Institute for VLBI in Europe, JIVE.

spacer.gifThe Santa Maria station (SMA) tracking footprint covers a large portion of the Atlantic ocean. The first launch to be tracked from Santa Maria will take place in early 2008, when Jules Verne, the first Automated Transfer Vehicle (ATV) to be sent to the International Space Station, lifts off from Europe's Spaceport in French Guiana on board an Ariane 5 launcher.

Press_conference_2008.jpg
spacer.gifThe conference began at 08:30 with breakfast, followed at 09:00 by a press briefing to review the Agencys activities in 2007 and look ahead to those of 2008, a year set to be full of events and marked by several major launches (ATV, Giove-B, GOCE, Herschel and Planck, SMOS, Vega), as well as a major programmatic milestone for ESA: the Council meeting at Ministerial level in late November.his project is co-funded by the European Space Agency as part of a programme dedicated to telemedicine. The aim is to test a satellite communication system, the only technology that would remain fully operational in the event of a natural disaster. The exercise demonstrates the efficiency of satellite telecommunications for intervention in the field while offering the possibility to inform the rest of the world about the evolution of the situation. This is a good example of what ESA wants to develop: a truly user-driven system enabling satellites to safely connect the health world.

ALMA - the highest and largest radio observatory
High in the Andes in northern Chile, one of the worlds most challenging projects is underway. A radio astronomy observatory with no less than 66 parabolic antennas is being built at an altitude of 5.000 metres a truly Herculean task.

GIOVE: Solid foundation for Galileo
Permalink  
 

GIOVEB.jpg
spacer.gifToday, the specialists at the European Space Agency's Research and Technology Centre in the Netherlands are able to confirm that the GIOVE-A mission is a success. This is an essential result for the next step in the programme: the launch of GIOVE-B, the second experimental satellite, scheduled for lift off by mid-2008. This satellite will broadcast the latest signals, which have been agreed with the United States, and two different types of onboard technologies that will provide the best timing synchronisation experienced so far. When complete, Galileo will be a constellation of 30 satellites supported by a network of ground stations, creating a global network. With this joint project, the European Commission and ESA plan a civil system providing guidance and assistance regardless of location. The fact that Galileo will be a civil system means it will guarantee continuity of access and signal quality - unlike the American GPS system, which is under military control. Nevertheless, Galileo and GPS will be compatible and interoperable - increasing the reliability of both systems.

ISSUPDATE_NOV2007.jpg
spacer.gifHarmony, also known as Node 2, was delivered to the International Space Station (ISS) by the STS-120 Shuttle mission last October. After STS-120 returned to Earth, the ISS Expedition 16 crew continued work to move Harmony to its final destination and get it ready to receive the next stage of the ISS: Europe's Columbus laboratory. Columbus has been installed in the cargo bay of Space Shuttle Atlantis, ready for launch at 22:31 CET (21:31 UT) on December 6th. Two European astronauts will deliver the European Columbus laboratory to the ISS on this historical space mission. During his 12 day mission to the ISS, ESA astronaut Hans Schlegel will undertake 2 spacewalks to install the laboratory. His colleague, Léopold Eyharts, will oversee the installation and the start-up of Columbus and its scientific facilities during a two month stay on board the Station. Once in place, the laboratory will begin to bear the fruits of Europe's investment in the International Space Station Programme.
