Astronauts complete marathon space walk
The astronauts fixed two cranes to the outside of the space station
Two astronauts from the space shuttle, Discovery, have completed the first space walk as part of their work to equip the International Space Station for permanent residence.
Tamara Jernigan and Daniel Barry were outside of the shuttle for seven hours 55 minutes - the second longest space walk ever made from the space shuttle.
At the end of the walk it seemed they were reluctant to go back inside.
"Wow. It feels like we just walked outside."
The bulky space suits - known as extravehicular mobility units, or EMUs - were kept low on pressure during the EVA to make them more manoeuvrable.
During the walk Barry exchanged greetings with his wife on the ground and thanked her for letting him spend their wedding anniversary high above the earth.
In the next stage of equipping the International Space Station (ISS) two other astronauts, a Canadian and a Russian, will enter the station to deliver two tons of supplies, ranging from spare parts and computers to rubbish bags and signs pointing to the emergency exit.
Food, water and clothing for the stations first inhabitants will also be stored on board.
Nasa officials say the ISS construction programme is the first truly international space mission with bringing together the US, Russia, Japan, Canada and Brazil with the 11 members of the European Space Agency.
The crew is also scheduled to test a number of new UCDs (urine collection devices) for astronauts of both sexes as a back up to the shuttle's toilet system.
Nasa says the UCDs will be tested in microgravity for fit, leakage, hygiene and ease of use, with a view to designing and evaluating improvements to "the male interface" attachment.
On Saturday Discovery made history becoming the first space vehicle to dock with the orbiting space station.
It is currently made up of two components - The Russian-built Zarya launched first, and the American-built Unity module.
The astronauts also installed a number of tool kits and foot holds - designed to fit both American and Russian space boots - in preparation for future construction missions.
Discovery is due to remain docked with the station until 3 June, before returning to Earth on 6 June.
