China names a Pakistani for its space station crew, but the only launch date is Pakistan's
The China Manned Space Agency says a Pakistani payload specialist will fly on Shenzhou 24 and return on Shenzhou 23. It gave no date and no name, and the 25 November launch Islamabad has cited comes from a minister, not from Beijing.
The only date anyone has given for a Pakistani astronaut's flight to China's space station comes from Islamabad, not Beijing. On 7 November the China Manned Space Agency announced that a Pakistani will join the Shenzhou 24 mission as a payload specialist, Xinhua reported. The agency named no astronaut and set no launch date. The date Pakistanis have been quoting, 25 November, was given in October by Planning Minister Ahsan Iqbal.
The agency says the Pakistani will make a short flight in orbit and return to Earth aboard Shenzhou 23, the spacecraft that docked at the Tiangong station in May. It calls the mission the first joint flight of Chinese and foreign astronauts in the history of China's manned space programme. If 25 November holds, the launch comes 18 days after the announcement. Until the agency publishes a date itself, that remains a Pakistani expectation and not a Chinese schedule.
What is known
In April the agency said Muhammad Zeeshan Ali and Khurram Daud had been chosen to begin training in China. It has not said which of them will fly. The programme rests on a February 2025 agreement between SUPARCO, Pakistan's space agency, and the China Manned Space Agency: two Pakistanis train in China and one joins a mission to Tiangong. From signature to 25 November is 21 months. Prime Minister Shehbaz Sharif, who met both candidates in April, called the mission a "matter of pride for the entire nation".
Beijing had signalled the timing only in general terms. In a Xinhua interview on 9 October, Yang Liwei, China's first astronaut, said the station would welcome its first foreign astronaut in the second half of this year and that the two Pakistani candidates had performed exceptionally well in training. He added that the station would become a global research platform for scientists worldwide. None of that fixes a day.
The seat arithmetic
A Shenzhou capsule seats three. The agency says the Pakistani will launch with the Shenzhou 24 crew and come home on Shenzhou 23, which has been docked at the station since May. That makes the visit a handover: the new crew arrives, and the old crew's spacecraft is the way down.
The sum then needs an explanation. If all three members of the Shenzhou 23 crew return in their own capsule, there is no fourth seat for a visitor. So either one of them stays on the station, or the visitor takes a seat that a regular crew member would otherwise have had. The agency has not said which. The answer matters because a guest who returns on a craft that has been docked since May leaves when that craft leaves, so the length of the visit follows the handover and not a separate plan. The agency calls it a short flight and has published no duration.
The mechanics are well established. Shenzhou crews launch on a Long March 2F rocket from Jiuquan in the Gobi desert, and recent missions have reached the station within hours. The return capsule lands on the ground in northern China. None of this has been confirmed for the Pakistani's flight, and the launch notice, when it comes, will be the first official sign of the schedule.
A payload specialist, in the agency's wording, is on board for experiments and not to run the station. Nothing published says what those experiments are, who proposed them, or whether SUPARCO or a Pakistani university supplies any equipment. China usually names its Shenzhou crews only around the launch, so the Pakistani's name may arrive days ahead, not weeks.
Who gains and what could slip
Pakistan gains a place on a crewed station that no foreign astronaut has yet boarded. China has been excluded from the International Space Station since 2011, when the United States barred NASA from working with Chinese space agencies, so Tiangong is the platform on which Beijing can offer partners a seat. China also aims to land astronauts on the Moon by 2030.
The risks to the date are the ordinary ones for crewed launches: the readiness of the Shenzhou 24 spacecraft and its rocket, the condition of the station, and a crew mix that Beijing has not explained. All of them are Beijing's to decide, so Pakistan's schedule depends on a calendar it does not control. Under the agreement only one of the two candidates joins a mission, so the other stays on the ground.
The next thing to watch is a launch notice from the agency. It has not confirmed 25 November, or any date, so far.
