The Ulysses legacy
For more than 17 years, the joint ESA/NASA mission Ulysses studied the heliosphere (the sphere of influence of the Sun) and our local interstellar neighbourhood, providing the first-ever map of the heliosphere in the four dimensions of space and time. Ulysses was designed to last for five years but it is still returning valuable data. The mission, which takes the spacecraft over the poles of the Sun, was extended four times, allowing Ulysses to pass over the Sun’s poles for a second and t ...

Galileo, time and spaceThe Galileo constellation will be the world's most reliable global navigation system. The technologies that have been developed to achieve such precision will also provide data for use in many other fields, such as oceanography and meteorology. The Galileo system will also open new horizons in fundamental sciences. The extremely small differences in timekeeping between the satellite clocks moving in orbit and their Earth-bound counterparts will lead scientists to a re-evaluation of the natu ...

ILA Space Pavilion: Space exploration in the futureTo land, first, on the Moon and, later, on Mars - in the 2030 timeframe - scientists need a mix of human and robotic missions to know in advance what challenges must be met - to know how humans can survive for years under microgravity, to scout landing zones and to develop precise navigation and artificial intelligence techniques.ESApod video programmeListen | Listen in your iPhone | Download | View full cache |
Earth Observation highlights at ILA Space PavilionEarlier this week, ESA signed a contract at the Berlin Airshow's Space Pavilion to build the EarthCARE satellite - the Agency's 'Cloud, Aerosol and Radiation' mission.

Traces of Martian life: the search continuesRadar sounders aboard ESA’s Mars Express and NASA’s Mars Reconnaissance orbiters have already detected ice deposits deep underground. Now, after a ten-month journey, NASA’s Phoenix lander will continue the search for water. Its objective is to land in a permafrost region near the north pole. Its suite of instruments will scan the atmosphere and a robotic arm will attempt to dig down to an ice-rich layer expected to lie at arm’s reach below the surface. But water is not the sole elem ...

Broadband internet via satellite aboard Thalys trainsThe principle is simple: a satellite-tracking antenna on the roof of the train ensures a permanent link with a telecommunications satellite. The link is then relayed inside the train through wireless access points installed in the ceilings of the carriages. A great technological achievement: a continuous, two-way link between a train travelling at 300 kilometres per hour and a satellite at an altitude of 36 000 kilometres. The technology demonstrator was developed with ESA support by the UK ... Listen | Listen in your iPhone | Download | View full cache |

Very Long Baseline Interferometry - the sharpest views of the invisibleRadio 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.
