A sick German astronaut has delayed by 24 hours a spacewalk that had been set for yesterday to attach the European-made Columbus laboratory to the orbiting International Space Station (ISS), a NASA spokesman said.
Just after the shuttle Atlantis docked with the ISS, mission chief John Shannon told reporters German astronaut Hans Schlegel, one of the Atlantis' crew of seven, was unwell, without giving details.
"We will delay the EVA [Extra Vehicular Activity, or spacewalk] by one day and Hans Schlegel will be excused," he said.

"It's a private medical matter," Shannon said. "I won't say more ... It's not life threatening."
He said the 11-day mission of the Atlantis would also be extended by one day, with return to Earth set for Feb. 19.
Schlegel will be replaced by US astronaut Stanley Love on the spacewalk which has been delayed until today, Shannon said.
His illness, the spokesman said, is "not going to impact any of the objectives of the mission," adding that Schlegel will still take part in the second spacewalk of the mission -- now rescheduled for Wednesday -- with US astronaut Rex Walheim.
A European Space Agency official who asked not to be identified said Schlegel's illness was "nothing serious." Images of Atlantis astronauts boarding the ISS showed a seemingly normal Schagel moving a little slower than his colleagues.
The Atlantis' third spacewalk by Walheim and Love has also been rescheduled, NASA said.
Before announcing the spacewalk delay, Shannon Sarafin said two minor technical glitches had been detected on the Atlantis. One of three navigational computers had failed -- posing no threat to the mission, he said -- and was about to be fixed.
The other glitch, he said, was a small tear in the shuttle's thermal blanket that appeared to be minor.
The announcements came a few hours after the Atlantis docked with the ISS on Saturday and the hatches between the two spacecrafts were opened allowing the visiting astronauts to be greeted by their three ISS colleagues.
The Atlantis mission to deliver the 10-tonne Columbus laboratory is marking a milestone in Europe's role in space.
Columbus, the first ISS addition not made in the US or Russia, will be used for biotechnology and medicine experiments involving microgravity. It cost 1.3 billion euros (US$2 billion), paid mostly by Germany, Italy and France.
Astronauts will use the ISS's robotic arm to transfer Columbus out of the shuttle's payload bay and attach it to the station.
On their first day in orbit on Friday the Atlantis crew trained a high-definition camera mounted on the shuttle's robotic arm on the spaceship's thermal shield to search for any damage that may have occurred during liftoff.
Shannon said three small foam losses from the shuttle's external fuel tank were filmed in the minutes after liftoff on Thursday, one of which may have struck the shuttle's thermal shield without, however, causing any apparent damage.
Examining the shuttle's heat shield became established procedure after the February 2003 shuttle Columbia disaster. A piece of foam insulation broke off during Columbia's liftoff, damaging the shuttle's external heat tiles and leading to the craft's destruction when it re-entered the Earth's atmosphere killing seven astronauts.
Besides Schlegel, the Atlantis crew includes astronaut Leopold Eyharts of France. Currently US and Russian astronauts are aboard the space station.
Eyharts will begin Europe's second longest stay on the space station by replacing US astronaut Dan Tani. The German astronaut of the European Space Agency, Thomas Reiter, stayed six months in the station in 2006.
The space shuttle was originally scheduled for blastoff on Dec. 6 as part of the tight schedule of shuttle flights to complete ISS construction by 2010, when the three-craft US shuttle fleet is to be retired.
But malfunctioning circuits in the fuel gauges of the spacecraft's liquid hydrogen tank forced a two-month delay until the problem was fixed.
READINESS: According to a survey of 2,000 people, 86 percent of Swedes believe the country is worth defending in the event of a military attack Swedes are stocking up on food items in case of war, as more conflict in Europe no longer feels like a distant possibility, and authorities encourage measures to boost readiness. At a civil preparedness fair in southwest Stockholm, 71-year-old Sirkka Petrykowska said that she is taking the prospect of hostilities seriously and preparing as much as she can. “I have bought a camping stove. I have taken a course on preservation in an old-fashioned way, where you can preserve vegetables, meat and fruit that lasts for 30 years without a refrigerator,” Petrykowska said. “I’ve set aside blankets for warmth, I
FRUSTRATIONS: One in seven youths in China and Indonesia are unemployed, and many in the region are stuck in low-productivity jobs, the World Bank said Young people across Asia are struggling to find good jobs, with many stuck in low-productivity work that the World Bank said could strain social stability as frustrations fuel a global wave of youth-led protests. The bank highlighted a persistent gap between younger and more experienced workers across several Asian economies in a regional economic update released yesterday, noting that one in seven young people in China and Indonesia are unemployed. The share of people now vulnerable to falling into poverty is now larger than the middle class in most countries, it said. “The employment rate is generally high, but the young struggle to
ENERGY SHIFT: A report by Ember suggests it is possible for the world to wean off polluting sources of power, such as coal and gas, even as demand for electricity surges Worldwide solar and wind power generation has outpaced electricity demand this year, and for the first time on record, renewable energies combined generated more power than coal, a new analysis said. Global solar generation grew by a record 31 percent in the first half of the year, while wind generation grew 7.7 percent, according to the report by the energy think tank Ember, which was released after midnight yesterday. Solar and wind generation combined grew by more than 400 terawatt hours, which was more than the increase in overall global demand during the same period, it said. The findings suggest it is
‘ARMED CONFLICT’: At least 21 people have died in such US attacks, while experts say the summary killings are illegal even if they target confirmed narcotics traffickers US forces on Friday carried out a strike on an alleged drug-smuggling boat off the coast of Venezuela, killing four people, US Secretary of Defense Pete Hegseth said. The latest strike, which Hegseth announced in a post on X, brings the number of such US attacks to at least four, leaving at least 21 people dead. An accompanying video shared by Hegseth showed a boat speeding across the waves before being engulfed in smoke and flames. “Four male narco-terrorists aboard the vessel were killed,” the Pentagon chief wrote. He said the strike “was conducted in international waters just off the
