Europe launches robot space freighter

Massive robot freighter designed to rendezvous automatically with the orbital space station.

   The European Space Agency on Sunday carried out the maiden launch of a massive robot freighter designed to rendezvous automatically with the orbital space station.
   The Automated Transfer Vehicle (ATV), a nearly 20-tonne payload the size of
a London double-decker bus, blasted into the skies aboard a beefed-up Ariane 5 launcher, an AFP reporter saw.
   After being placed in orbit, the cylinder-shaped craft will deploy its
solar panels and gently find its way to the International Space Station (ISS)
and berth with it.
   The launch had initially been scheduled for Saturday but was postponed for
further checks.
   The ATV will deliver seven and a half tonnes of food, water, pressurised
air, fuel and personal items to the ISS crew.
   After docking, the ATV will use its engines to propel the station, which is
being gently tugged earthwards by terrestrial gravity and lingering
atmospheric molecules, to a safer height in low orbit.
   After six months or so, the craft will detach from the ISS, taking with it
rubbish accumulated during the station's mission. The trash and freighter will
then safely disintegrate over the Pacific, mission scientists say.
   Weighing 11 tonnes unloaded, measuring 10.3 metres (33.5 feet) long and 4.5
metres (16.25 feet) wide and laden with hi-tech optical navigation, docking
sensors and communications equipment, the ATV has cost ESA 1.3 billion euros
(1.96 billion dollars).
   The payload, handled by an Ariane 5 ES, is the biggest undertaken by ESA
   It will be placed in orbit at an altitude of 260 kilometres (160 miles),
and then take about two weeks to edge up to the ISS, in order to test its
systems and wait patiently for the departure of a US space shuttle, the
Endeavour, before docking with the station.
   Deployment of the ATV has been put off for some four years because of
delays in assembling the ISS after the loss of the shuttle Columbia in
February 2003.
   The first ATV is named after Jules Verne, the French author who pioneered 
science fiction. Four more cargo ships are in the works, with their assembly
and launch each costing just over 300 million euros.
   Europe's other major contribution to the ISS has been a 1.4-billion-euro
science module which was attached to the burgeoning orbital outpost last month.
   The ISS, whose assembly began in 1998, now has a mass of more than 240
tonnes and is so big that it can be seen at night with the naked eye,
perceptible as a small, moving star (location details on
   French Foreign Minister Bernard Kouchner and European affairs minister
Jean-Pierre Jouyet hailed the successful launch as a "result of European
cooperation in strategic top technology".
   "France and Germany, which had a special role in developing this space
craft, are today reaping the benefits of their cooperation," they said in a
joint statement.
