## The US space shuttle Atlantis has undocked from the International Space
Station, bringing to an end its 25-year career.

The crews of both spacecraft bade their farewells and closed the hatch closure
shortly after noon on Sunday, NASA officials said.
The undocking caps the shuttle's 25-year career during which it has logged
some 115 million miles. It is due back in Florida on Wednesday.
Only two more shuttle launches remain - one in September for Discovery and the
final blast off for Endeavour in November - before the curtain falls on this
era of human space flight.
The United States will then rely on Russia to take astronauts to the station
aboard three-seater Soyuz spacecraft until a new fleet of commercial "space
taxis" is operational.
On Friday, Atlantis astronauts Garrett Reisman and Michael Good completed the
mission's final spacewalk at the station that lasted six hours and 46 minutes.

The pair plugged a new ammonia jumper cable into the orbiting space station's
huge framework and installed two new batteries that store energy collected by
the station's large solar panels.
Each battery weighs 375 pounds and measures about the size of a three-foot
box. The astronauts swapped out another four batteries during another
spacewalk on Wednesday.
Batteries usually last five to six years but the ones that were replaced had
functioned for nine years. The old batteries will be brought back to Earth
aboard Atlantis.
During the 12-day mission, Atlantis and its six-member crew unloaded over 12
tons of equipment, including the communications antenna, power storage
batteries and a radiator.
The biggest single element is the five-ton Rassver research module, or MRM-1,
which will provide additional storage space and a new docking port for Russian
Soyuz and Progress spacecraft.
The Rassver - "Dawn" in Russian - was permanently attached to the bottom of
the space station's Zarya module. It carries important hardware on its
exterior including a radiator, airlock and a European robotic arm.
