GIOVE-B

GIOVE-B will be a satellite very close to the satellites planned for the operational Galileo system to be deployed by 2013. In particular it will carry a high precision atomic clock which, once on orbit, will be the most accurate clock ever flying in space. With this launch the European Space Agency and the European Commission are consolidating the foundations of Galileo, the first global civil positioning system.ESApod video programme...

ATV: Closing in on the target

Jules Verne ATV's laser rendezvous sensor will emit a signal and receive a reflection back from the International Space Station. Engineers at the ATV Control Centre and the astronauts on board ISS will monitor the spacecraft as it approaches for docking, making sure it follows a predefined corridor and that the spacecraft is flying at the right angle. This complex system has back-up layers which will kick in if there are any problems. But should its two redundant chains break down, the ATV has a...

ATV orbital rehearsals for ISS docking

On 14 March, ATV successfully demonstrated the crucial Collision Avoidance Manoeuvre, or CAM, in which an automated system successfully took over control of the vessel and moved to a safe location. Now, two more 'Demonstration Days' are scheduled prior to the actual docking. The first, 29 March, will demonstrate that the ATV can automatically calculate its position and manoeuvre with respect to the Station using relative GPS navigation; it will also perform an 'Escape' manoeuvre from the S2 posi...

Moons

A number of missions have spent time exploring these unknown worlds in the solar system. In January 2005, the European lander, Huygens stunned the world as it landed on Saturn's largest moon, Titan, revealing unexpected data. Missions such as ESA's SMART-1, which compiled the first comprehensive inventory of key chemical elements in the lunar surface and tested new technology, have become increasingly important today. To follow-up on the technological breakthroughs of SMART-1, ESA will be part...

Jules Verne ATV's space cargo

Provided by Thales Alenia Space in Italy, Jules Verne ATV’s Integrated Cargo Carrier is about half the volume of ESA’s Columbus laboratory. Around 180 kg of European cargo was first packed in Italy before being transported to Kourou, in French Guiana. Before the cargo was loaded into the spacecraft, the entire pressurised section was disinfected as a sanitary precaution. Some 1200 kg of supplies, mainly from NASA, were stored on board, including 500 kg of food, and 80 kg of clothing and spare pa...

ATV: A new generation space vehicle

The 48 cubic meter pressurised cargo module gives the ATV a capacity three times greater than existing space freighters. Its racks can be packed with more than 1300 kg of food, clothes, and equipment. Reservoirs can carry several hundred litres of drinking water and gases. Other tanks are loaded with important quantities of propellants. Astronauts will unload the cargo at their leisure, and use it as a storage area. Unwanted items and refuse placed inside will burn up when the vessel re-enters t...

ATV: Rendezvous in space

From 1998, the International Space Station has required regular visits - to date 58 dockings - of the Shuttles, Soyuz crew, and Progress supply ships. Unmanned - but man-rated – ESA's Automated Transfer Vehicle (ATV) has the unique capability to perform automatic rendezvous in a fully autonomous manner. The rendezvous of ESA's Jules Verne ATV with the ISS uses GPS navigation, star tracker devices, two critical sensors, a telegoniometer and a videometer. After raising its orbit to some 400 kilom...

ATV Control Centre readies for Europe's first-ever automated docking

Equipped with its own propulsion and navigation system, the unmanned ATV "space truck" - dubbed 'Jules Verne' - has a sophisticated automatic navigation system. Even though the ATV is an automatic space vehicle, ground control experts from ESA and CNES, the French space agency, will be heavily involved in operations. They are prepared for any contingency, determining the route the spacecraft must take to dock with the ISS and working closely with the other two ISS control centres involved in ATV...

SMOS: Helping Europe respond to climate change

Three-quarters of the globe is covered in water and its influence is felt everywhere. It’s not only oceans, rivers and lakes that affect the climate but water in all its forms, such as soil moisture and its evaporation. SMOS, ESA’s 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 pro...

The multinational team must work as one to react immediately and effectively.

Very Long Baseline Interferometry - the sharpest views of the invisible

Radio 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 h...

This 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 de...

The European orbiter has identified broad meteorological regimes, all influenced by the gigantic hurricane-like vortices at the poles. From these double-eyed vortices, swirling in the atmosphere, around the planet in just a couple of days, to smoother streams at mid-latitudes and wave-dominated phenomena at lower latitudes - these regimes are, surprisingly, clearly delineated.
