Astronauts aboard the space shuttle Atlantis are carrying out a spacewalk to help install Europe's Columbus laboratory on the space station. | |
The outing was originally scheduled for Sunday, but had to be delayed by 24 hours after European crew member Hans Schlegel was taken ill. | |
Mr Schlegel was replaced by astronaut Stan Love, who ventured into space with his American colleague Rex Walheim. | |
Atlantis docked with the International Space Station (ISS) on Saturday. | |
The US space agency (Nasa) has refused to elaborate on what was ailing German astronaut Hans Schlegel, but said it was not life-threatening. | |
Nasa's website said that the medical issue would have "no impact to the overall mission objectives". | |
Schlegel is expected to take part in the second spacewalk of the mission on Wednesday. | |
The primary purpose of the spacewalk, which began shortly after 1430 GMT (0930 EST), is to help install the European space laboratory, Columbus. | |
Mr Schlegel will now be replaced on Monday's spacewalk"Welcome to spacewalking buddy," Mr Walheim said as Love made his way through the hatch for his first spacewalk. | Mr Schlegel will now be replaced on Monday's spacewalk"Welcome to spacewalking buddy," Mr Walheim said as Love made his way through the hatch for his first spacewalk. |
