A medical problem with a crew member has delayed the first spacewalk of the Space shuttle Atlantis's mission to the International Space Station.
Nasa refused to elaborate on what was ailing German astronaut Hans Schlegel, but said it was not life-threatening.

The Progress M-62 cargo ship has successfully undocked from the International Space Station (ISS).

"The Progress M-62 was undocked from the ISS at 1:32 p.m. Moscow time (10.32  GMT), but will not be de-orbited at once. It will be temporarily turned into a test lab before being buried at the 'spacecraft cemetery' in the Pacific" - Valery Lyndin, Mission Control spokesman

The space station's two American astronauts went out on a riskier-than-usual spacewalk Wednesday to fix one of two equipment failures that have crippled their power system and threatened to stall construction.
Wednesday's spacewalk was especially hazardous because of the risk of being shocked. For safety, Whitson and Tani waited until the international space station was on the dark side of Earth, then carefully undid fasteners and disconnected cables, and pulled out the old electric motor.

The crew aboard the International Space Station (ISS) are preparing for a spacewalk, on Wednesday, January 30, 2008
Expedition 16 commander Peggy Whitson and flight engineer Dan Tani will replace a faulty motor that controls a beta gimbal joint at the base of one of the space stations starboard solar arrays, and hopefully restore some of the power-generating ability of the solar wings.
Trickily, the pair will have to begin work as the ISS passed into the earths shadow. This is because high power levels will pass through the solar arrays if the sun shines onto them, and potentially shock the space walkers. And, the crew has only 33-minutes of work time when the station is in darkness.
The International Space Station orbits the Earth in about 91 minutes at its altitude of about 184 nautical miles (341 kilometres) above the surface of Earth.
NASA TV will broadcast the Expedition 16 crew's fifth spacewalk live at 09:00 GMT (4:00 EST).

 The orbit of the International Space Station's  has been raised by 5.25 kilometres to an altitude of 340 kilometres.

"The correction of the ISS orbit was completed successfully" - Mission Control Spokesperson.

The Russian Zvezda service module's  engines were activated for 118 seconds, raising the  orbit to provide better conditions for the docking  of the Progress M-63 cargo spacecraft and the space shuttle Atlantis, whose launches are scheduled for the first half of February.

A proposal for the UK to join the International Space Station (ISS) project has been put forward by a group of scientists and engineers.
Their idea is for Britain to build and launch two modules that greatly enhance living conditions on the platform.
The Habitation Extension Modules would increase meeting and bunk space; and allow the UK to fly some dedicated science experiments.
The proposal is being supported by the British Interplanetary Society.

A pair of space station astronauts ventured out on a spacewalk Tuesday to inspect two defective mechanisms that are hobbling power generation at the orbiting complex.
Flight controllers called it a fact-finding mission.
Meanwhile, some 200 miles below, NASA was trying to recreate fuel gauge problems that grounded shuttle Atlantis earlier this month.
Engineers started filling the spaceship's external tank with liquid hydrogen fuel at daybreak, in a test at the launch pad to pinpoint the nagging trouble. The problem could be anywhere in the 100 feet of circuitry between the shuttle and tank, or in the fuel gauges.

 Two astronauts on the International Space Station will make a spacewalk next week to find out if a micro-meteor strike damaged a critical part of the outpost's power system, officials said on Thursday.
The station is not in any danger and is still producing enough power to support the arrival of Russian cargo ship later this month, said station deputy program manager Kirk Shireman.
