China launched a three-member crew to its orbiting space station on Thursday as part of its ambitious program that aims to put astronauts on the moon by 2030.
The Shenzhou-18 spacecraft lifted off from the Jiuquan Satellite Launch Center on the edge of the Gobi Desert in northwestern China atop a Long March 2-F rocket at 8:59 p.m. (1259 GMT).
The spacecraft’s three-member crew will relieve the Shenzhou-17 team, which has been manning China’s Tiangong space station since last October.
The China Manned Space Agency, or CMSA, held a send-off ceremony — complete with flag-waving children and patriotic tunes — for the Shenzhou-18 crew earlier on Thursday, as the three astronauts prepared to enter the spacecraft.
The trio is made of Commander Ye Guangfu, 43, a veteran astronaut who took part in the Shenzhou-13 mission in 2021, and fighter pilots Li Cong, 34, and Li Guangsu, 36, who are spaceflight rookies.
They are expected to reach the space station about six-and-a-half hours after liftoff, The Associated Press reported.
China built its own space station after being excluded from the International Space Station, largely because of US concerns over the Chinese military’s involvement in the program. This year, the station is slated for two cargo spacecraft missions and two manned spaceflight missions.



Latest Tests Show Seine Water Quality Was Substandard When Paris Mayor Took a Dip

Tests results released Friday showed the water quality in the River Seine was slightly below the standards needed to authorize swimming — just as the Paris Olympics start.

Heavy rain during the opening ceremony revived concerns over whether the long-polluted waterway will be clean enough to host swimming competitions, since water quality is deeply linked with the weather in the French capital.

Paris Mayor Anne Hidalgo took a highly publicized dip last week in a bid to ease fears. The Seine will be used for marathon swimming and triathlon.

Daily water quality tests measure levels of fecal bacteria known as E. coli.

Tests by monitoring group Eau de Paris show that at the Bras Marie, E. coli levels were then above the safe limit of 900 colony-forming units per 100 milliliters determined by European rules on June 17, when the mayor took a dip.

The site reached a value of 985 on the day the mayor swam with Paris 2024 chief Tony Estanguet and the top government official for the Paris region, Marc Guillaume, joined her, along with swimmers from local swimming clubs.

At two other measuring points further downstream, the results were below the threshold.

The statement by Paris City Hall and the prefecture of the Paris region noted that water quality last week was in line with European rules six days out of seven on the site which is to host the Olympic swimming competitions.

It noted that "the flow of the Seine is highly unstable due to regular rainfall episodes and remains more than twice the usual flow in summer," explaining fluctuating test results.

Swimming in the Seine has been banned for over a century. Since 2015, organizers have invested $1.5 billion to prepare the Seine for the Olympics and to ensure Parisians have a cleaner river after the Games. The plan included constructing a giant underground water storage basin in central Paris, renovating sewer infrastructure, and upgrading wastewater treatment plants.
