A Chinese astronaut on Saturday performed the nation’s first-ever spacewalk, the latest milestone in an ambitious program that is increasingly rivaling the US and Russia in its rapid expansion.
Mission commander Zhai Zhigang (翟志剛), 42, floated out of the orbiter module’s hatch in the spacewalk, shown live on state broadcaster CCTV. Tethered to handles attached to the Shenzhou 7 ship’s orbital module’s exterior, Zhai remained outside for about 13 minutes before climbing back inside and closing the hatch behind him.
“Shenzhou 7 has left the module. I feel well. I am greeting the Chinese people and the people of the world,” Zhai said.

Fellow astronaut Liu Boming (劉柏明) also emerged briefly from the capsule to hand Zhai a Chinese flag that he waved for an exterior camera filming the event. The third crew member, Jing Haipeng (景海鵬), monitored the ship from inside the re-entry module.
Zhai slowly moved toward a test sample of solid lubricant placed outside the orbital module, Xinhua news agency said.
He took the sample and handed it over to Liu who stayed in the orbital module and closely monitored Zhai’s moves.
During his mission, Zhai tested his 120kg, Chinese-made protective suit, which cost US$4 million to US$30 million, various state media reports said.
Zhai returned to the Shenzhou 7’s orbital module, closing its hatch shortly before 5pm, state TV said.
The walk was supposed to last 20 minutes, with no immediate explanation given for the shortened length of time.
Although Zhai’s maneuvers represented the 298th spacewalk of all time, it was a milestone for China. President Hu Jintao (胡錦濤) watched it at the mission control center in Beijing, where applause broke out as Zhai floated out of the spacecraft.
The successful spacewalk paves the way for assembling a space station from two Shenzhou orbital modules, the next major goal of China’s manned spaceflight program. China is also pursuing lunar exploration and may attempt to land a man on the moon in the next decade.
China launched its first manned mission, Shenzhou 5, in 2003, followed by a two-man mission in 2005.
Since blasting off from their northwestern China launch base on Friday, the astronauts had been largely occupied with preparing the suits and adapting to zero gravity. Meals aboard the craft have followed a typical Chinese menu, featuring versions of kung pao chicken, shrimp and dried fruit, Xinhua news agency said.
On Friday, the three-module capsule shifted from an oval orbit to a more stable circular orbit 343km above Earth, meaning it is circling at a constant distance.
TURNAROUND: The Liberal Party had trailed the Conservatives by a wide margin, but that was before Trump threatened to make Canada the US’ 51st state Canada’s ruling Liberals, who a few weeks ago looked certain to lose an election this year, are mounting a major comeback amid the threat of US tariffs and are tied with their rival Conservatives, according to three new polls. An Ipsos survey released late on Tuesday showed that the left-leaning Liberals have 38 percent public support and the official opposition center-right Conservatives have 36 percent. The Liberals have overturned a 26-point deficit in six weeks, and run advertisements comparing the Conservative leader to Trump. The Conservative strategy had long been to attack unpopular Canadian Prime Minister Justin Trudeau, but last month he
OPTIMISTIC: A Philippine Air Force spokeswoman said the military believed the crew were safe and were hopeful that they and the jet would be recovered A Philippine Air Force FA-50 jet and its two-person crew are missing after flying in support of ground forces fighting communist rebels in the southern Mindanao region, a military official said yesterday. Philippine Air Force spokeswoman Colonel Consuelo Castillo said the jet was flying “over land” on the way to its target area when it went missing during a “tactical night operation in support of our ground troops.” While she declined to provide mission specifics, Philippine Army spokesman Colonel Louie Dema-ala confirmed that the missing FA-50 was part of a squadron sent “to provide air support” to troops fighting communist rebels in
PROBE: Last week, Romanian prosecutors launched a criminal investigation against presidential candidate Calin Georgescu accusing him of supporting fascist groups Tens of thousands of protesters gathered in Romania’s capital on Saturday in the latest anti-government demonstration by far-right groups after a top court canceled a presidential election in the EU country last year. Protesters converged in front of the government building in Bucharest, waving Romania’s tricolor flags and chanting slogans such as “down with the government” and “thieves.” Many expressed support for Calin Georgescu, who emerged as the frontrunner in December’s canceled election, and demanded they be resumed from the second round. George Simion, the leader of the far-right Alliance for the Unity of Romanians (AUR), which organized the protest,
ECONOMIC DISTORTION? The US commerce secretary’s remarks echoed Elon Musk’s arguments that spending by the government does not create value for the economy US Secretary of Commerce Howard Lutnick on Sunday said that government spending could be separated from GDP reports, in response to questions about whether the spending cuts pushed by Elon Musk’s Department of Government Efficiency could possibly cause an economic downturn. “You know that governments historically have messed with GDP,” Lutnick said on Fox News Channel’s Sunday Morning Futures. “They count government spending as part of GDP. So I’m going to separate those two and make it transparent.” Doing so could potentially complicate or distort a fundamental measure of the US economy’s health. Government spending is traditionally included in the GDP because
