CAPE CANAVERAL, Florida (Reuters) - The space shuttle Atlantis was fueled for liftoff on Friday to deliver a Russian module and equipment to the International Space Station, the last planned flight for the 25-year-old spaceship.
Technicians at the Kennedy Space Center in Florida began pumping 500,000 gallons (1.9 million liters) of liquid oxygen and liquid hydrogen into Atlantis' fuel tank in preparation for a launch attempt at 2:20 p.m. (1820 GMT).
Meteorologists predicted a 70 percent chance the weather would be suitable for liftoff.
Atlantis carries a small laboratory and docking compartment that will be attached to the Russian side of the space station, a $100 billion project of 16 nations nearing completion after more than a decade of construction 220 miles above the Earth.
The Mini Research Module, nicknamed "Rassvet" -- Russian for dawn -- shares Atlantis' payload bay with a cargo carrier loaded with batteries, a spare communications antenna and an attachment for the station's Canadian-built robotic crane.
NASA intends to stock the station with as many spare parts as possible before turning over cargo resupply to smaller and less capable ships run by Russia, Europe and Japan.
NASA hopes commercial U.S. carriers will eventually pick up the bulk of its station cargo business and possibly also crew transport, which is now provided solely by Russia.
To help get the station ready for operations after the shuttles are retired, the Atlantis astronauts plan to swap out six 365-pound (166 kg) solar array batteries on the station's main power truss, a task that will take the better part of two spacewalks.
TWO MORE SHUTTLE TRIPS PLANNED
Another spacewalk is to be devoted to installing a second communications antenna to the station's truss.
After Atlantis returns, NASA plans just two more trips to the space station with its shuttles.
Discovery is targeted for launch in September with spare parts and equipment. Endeavour is due to launch in November carrying a $2 billion, multinational particle detector known as the Alpha Magnetic Spectrometer.nike running shoes
