A European supply ship will undock from the International Space Station on Saturday as scheduled but be destroyed 12 days earlier than planned because of a power hitch, the European Space Agency (ESA) said Friday.

The Automated Transfer Vehicle (ATV) Georges Lemaitre will separate from the ISS on Saturday at 1344 GMT at the end of its six-month mission, it said.

But the loss of one of its four power sources means that, as a precaution, the ATV will be destroyed on Sunday rather than on February 27 as initially planned.

"It's a minor concern rather than a critical problem," Dominique Siruguet, deputy head of ESA's ATV programme, told AFP.

"The ATV has four solar panels," he said.

"It can operate as normal using three power chains, but even if this were reduced to two, it would still be able to separate from the ISS and perform re-entry satisfactorily."

Re-entry entails sending the vehicle earthward at a steep angle so that it burns up on friction with the atmosphere at hypersonic speeds.

The ATV is the fifth and final cargo ship that ESA contracted to provide for the US-led ISS project.

Named after the father of the "Big Bang" theory, the spaceship is designed to navigate by starlight and dock automatically with the manned outpost in space.
