Latest Galileo Satellite Arrives

Europe's latest Galileo navigation satellite has arrived at the Agency's technical centre in the Netherlands for testing, as the previous two satellites are prepared for shipping to French Guiana for launch this summer.

ESA's completion of a pair of dedicated ground stations at opposite ends of Europe has enabled Galileo satellites in orbit to participate in global testing of the Cospas-Sarsat search and rescue system.

Jupiter's moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high (about 400 kilometers). However, concentrations of volcanic activity are significantly displaced from where they are expected to be, based on models that predict how the moon's interior is heated, according to NASA and European Space Agency researchers.

Eight more Galileo navsats agreed

ESA today signed a contract to build a further eight Galileo satellites, alongside other agreements to modify Europe's Ariane 5 launcher to carry four navigation satellites at a time.

Four hundred years ago on this day Galileo Galilei, considered by some to be the Father of Modern Science, demonstrated his first telescope to the merchants of Venice. In building his first telescope and with his subsequent observations of the moons of Jupiter he set the stage to later argue in favour of the sun-centered Copernican theory of the universe. Unfortunately for Galileo his work and support of the the sun-centered theory would be considered close to heresy by the Catholic church which would eventually try him and place him under house arrest.
