Japan's space lab about to get bigger
By MARCIA DUNN
AP Aerospace Writer
CAPE CANAVERAL, Fla. (AP) -- The newest space station addition, a giant Japanese science lab, is about to get bigger. After installing TV cameras and removing covers during a spacewalk Thursday, the astronauts at the linked shuttle and station got ready for their next challenge: attaching a storage shed to the bus-size lab. The 210-mile construction job was set for Friday afternoon.
The lab, named Kibo, Japanese for hope, is so big that it had to be split into three shuttle missions to get to the international space station. Its 14-foot storage shed was delivered in March and left in a temporary parking spot. The third and final section, a porch, will be launched next spring.
Spacewalkers Michael Fossum and Ronald Garan Jr. looked like puffy white dolls Thursday against the 37-foot-long, 14-foot-wide lab, which is now the space station's biggest room.
It was their second spacewalk in three days.
"I feel like I'm on a camping trip trying to pack up a wet tent on a Sunday morning," Fossum said as he wrestled with some of the lab's insulation. He and Garan removed thermal covers from the lab's robot arm and added them to a variety of attachment points.
As the spacewalkers toiled outside, their eight colleagues hauled more experiment racks into the billion-dollar lab, and flight controllers near Tokyo monitored the power systems.
"Lots of people at work in there," astronaut Kenneth Ham informed the spacewalkers.
"No, there's not. I don't see anybody," one of the spacewalkers said.
"They got tired of your banging on the roof," Ham answered.
Even with all the racks moving in, Kibo was still noticeably bigger than the eight other rooms at the space station. "We have not seen that much space in space since Skylab," Mission Control told the astronauts in a written message. Skylab was NASA's first space station, back in the 1970s.
Space shuttle Discovery's astronauts delivered and installed Kibo earlier in the week. There are now three labs at the orbiting complex, supplied by NASA, the European Space Agency and, now, the Japanese Space Agency.
On Saturday, the astronauts will test drive Kibo's 33-foot robot arm. The two TV cameras that were set up on the lab's exterior Thursday will be instrumental in those robot-arm operations.
And on Sunday, one final spacewalk will be conducted to replace an empty nitrogen-gas tank at the space station. Fossum and Garan got a head start on that work Thursday.
Just before the seven-hour spacewalk ended, Fossum checked the solar wing rotating joint on the space station's left side. He found streaks of white grease, but no metal shavings like those that are clogging an identical joint on the right side.
Flight director Annette Hasbrook said the left joint looked to be in fine shape and noted that the leaked grease actually may be preventing a buildup of friction between the moving parts.

IISS: Israel has sizeable nuclear arsenal
The London-based International Institute for Strategic Studies (IISS) has affirmed in a report that Israel has a 'sizeable' nuclear arsenal.
The report stated that Israel was considered to be a "de facto nuclear power with an advanced and sizeable arsenal," even though the regime had never itself acknowledged openly its nuclear-weapons status, DPA reported.
"The fundamentals of Israel's nuclear capabilities and policies, though never officially confirmed, are accepted as fact throughout the world," the IISS stated.
Israel is widely beleived to have more than 200 nuclear warheads.
The report shows that in the 11 months between February 2006 and January 2007, at least 13 countries in the Middle East announced new or revived plans to pursue or explore civilian nuclear energy.

'No bias' against UK astronauts
Although the UK has a longstanding opposition to human spaceflight, its policies will not stop its citizens becoming astronauts, the European Space Agency (Esa) says.
"The UK currently refuses to fund human spaceflight, believing robotics to be a more worthwhile space activity."
"Officials made it clear at the start of a recruitment drive in London that Britons were very welcome to apply."
50,000 applicants are expected to apply and will be trimmed down to four astronauts. Those 4 will then begin training for stays at the ISS.
If your interested in applying, Esa says it will only take on new candidates between the ages of 27 and 37. Successful candidates will probably be experienced scientists or test pilots.
"The UK has a huge skill in robotics and the question is: should it continue to keep this divide on robots versus humans, or should we now widen our ambitions?"

First South Korean astronaut is in space!
Yi So-yeon, a 29-year-old bio-engineer, had been chosen as the backup candidate for the flight out of about 36,000 applicants for the mission. When the first choice was disqualified for breaking space center rules, Yi got the call. She'll spend 10 days in space at the International Space Station conducting experiments, and will return to earth on April 19th.

Space Station Robot Asks to be Called Dextre the Magnificent
"In a surprising and potentially troubling request, the new space station robot known as Dextre demanded that astronauts refer to it in the future at 'Dextre the Magnificent.' Brandishing power tools that would make any handyperson blush, the mobile servicing system thanked humans for creating it and promised a glorious future where humans would retain an important role in the new robot order."

Review finds no link between Al-Qaeda and Saddam Hussien
An exhaustive review of over 600,000 documents has found that there was indeed no link between Al Qaeda and Saddam Hussien. They were alleged by some U.S. Government officials to have established a highly secretive relationship between 1992 and 2003, specifically through a series of meetings reportedly involving the Iraqi Intelligence Service, and this notion was used as a justification for a war with Iraq following the September 11th terrorist attacks.
The study which has gone through what has been described as a "painful" declassification, was sponsored by the pentagon and found that Hussien did support other terrorists in a campaign against anyone who stood against his regime. Despite this, there was no "direct operational link" between Al-Qaeda and Hussien as once alleged.
