A pair of spacewalking astronauts have floated outside the International Space Station for the first of a two-part outing to complete installation of the newly arrived Harmony connecting module.

Two astronauts went out on a spacewalk at the international space station on Friday, picking up where the shuttle Discovery crew left off just days ago.

NASA says it will extend the space shuttle Discovery's mission by one day to allow for a closer inspection of a flawed rotary joint that turns the solar arrays aboard the International Space Station (ISS).

U.S. astronauts will make the first of five spacewalks from the International Space Station on Friday, to attach a node to the station brought by the Discovery shuttle, NASA said.

Discovery linked up with the international space station Thursday, and its staff is ready to start the most meticulous construction work ever endeavoured.

The U.S. Space Shuttle Endeavour has lifted off into space late Wednesday from Cape Canaveral, Florida and is heading towards the International Space Station for a construction mission. As Cindy Saine reports from Washington, the spotlight is on teacher-turned-astronaut Barbara Morgan.

The NASA space shuttle Endeavour will be launched to the International Space Station from Cape Canaveral at 6:36 p.m. local time (10:36 p.m. GMT) Wednesday, a NASA spokesman said.

Russian Mission Control said Tuesday it successfully adjusted the International Space Station's orbit in preparation for the docking of the U.S. space shuttle Endeavor, due to be launched August 8.

Two crew members of the International Space Station have begun a spacewalk that includes the removal of an outdated ammonia reservoir, a NASA Houston mission control spokesperson said Monday.

Restoration of a failed computer system returned regular rhythm on the international space station Sunday, as two astronauts made the fourth spacewalk since space shuttle Atlantis docked with the outpost a week ago.

Russian specialists monitoring the current Atlantis mission to the International Space Station said the U.S. space shuttle's crew were preparing for their first spacewalk Monday, a day after docking with the orbital station, run jointly by Russia's Federal Space Agency and NASA.

Two Russian cosmonauts have returned to the International Space Station after successfully completing their second space walk in eight days.
