China Space Station Tiangong

HELSINKI — China and Pakistan have signed an astronaut training agreement that could see the first international astronaut arrive at the Tiangong space station.

The China Manned Space Engineering Office (CMSEO) and the Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) signed the “Agreement on the Selection and Training of Pakistani Astronauts and Their Participation in China’s Space Station Missions” in Islamabad, Pakistan, Feb. 28, CMSEO announced.

The signing ceremony took place at the Prime Minister’s Office and was witnessed by Pakistani Prime Minister Shahbaz Sharif, Lin Xiqiang, deputy director of CMSEO, and Mohammad Yousaf Khan, chairman of SUPARCO.

The agreement marks the first time that China will select and train international astronauts, with a Pakistani astronaut to later fly to the Chinese space station.

According to the plan, the selection process will be completed within approximately one year, after which the Pakistani astronaut will undergo comprehensive and systematic training in China, according to the CMSEO statement.

“Pakistani astronauts will be arranged to enter the Chinese space station with Chinese astronauts to perform short-term flight missions in the next few years,” the CMSEO statement read.

Tiangong is a three-module space station constructed across 2021 and 2022, and was the ultimate goal of a Chinese plan approved in 1992 to develop human spaceflight capabilities.

The space station has so far hosted seven three-person crews of Chinese astronauts during its construction and operational phases. These range from Shenzhou-12, launched in June 2021, to the ongoing Shenzhou-19 mission.

It is unclear how the astronaut will take part in a short-term mission. Shenzhou missions to Tiangong are typically six months long, with three crew members required to operate the station. China has stated plans exist to expand Tiangong to six modules, and send a larger new-generation crew spacecraft to Tiangong on the new Long March 10 launcher.

The development is part of China’s broader space diplomacy efforts, as well as the Belt and Road Initiative, says Bleddyn Bowen, an associate professor in Astropolitics at Durham University in the United Kingdom.

“It certainly fits into China’s wider Belt and Road Initiative which Pakistan is a major part of, and the larger messaging China deploys around its role as a supplier of high technology capabilities for the developing world or “Global South,”” says Bowen.

The agreement will benefit both China and Pakistan, positioning the former as a leader in space, while providing otherwise unobtainable opportunities to the latter.

“Many smaller or poorer states want to participate in space programs and this is a high level, symbolic demonstration that China can be that platform and bigger partner for smaller space powers,” says Bowwen.

“This is a successful outcome for the Pakistani Government as it can show a pathway for Pakistan’s science and technology industries, sectors, and enthusiasts that it can participate in larger space missions despite never being able to muster the same kind of resources as its perennial rival, India” Bowen added.

The development will also be noted by other space-faring nations, including China’s rivals in space.

The U.S., as the lead for the International Space Station (ISS), is aiming to deorbit the orbital outpost in 2030. However, Elon Musk, SpaceX Chief Executive and close advisor to the U.S. President Donald Trump, has recently called for deorbiting the ISS “as soon as possible.”

NASA ISS transition plans include getting commercial space stations by 2030. Executives at companies engaged in commercial space station plans have, however, called for NASA and Congress to take fiscal and policy steps to avoid a space station gap which they fear could cede leadership in low Earth orbit to China. India will likewise take note of the development.

“India and the U.S., like China, have long sought to use their respective space programs to attract partners and participants that also meet foreign policy and diplomatic goals,” said Bowen.

“India particularly has long seen itself as the champion of the developing or Third World in space. I would watch closely to see if India will offer an early slot on their imminent human spaceflight and space station program to another country,” he added.

Monkey see, monkey do.

They see India doing it, and now they want to do the same. Doesn't matter they learn nothing from it.

Same with their "moon mission". All the jhumla about their icube or what ever, and it sent two crappy pictures and since then we haven't heard a peep about the project, nor has anything even remotely space related come up from that sink-istan. Another free ride by the Chinese, this time a much costlier one.

A Long March 6 carrier rocket carrying the satellite Tianping-3A 02 blasts off from the Taiyuan Satellite Launch Center in North China's Shanxi province, April 3, 2025

TAIYUAN -- China sent a new satellite into space on Thursday from the Taiyuan Satellite Launch Center in North China's Shanxi province.

The satellite, Tianping-3A 02, was launched at 10:12 am (Beijing Time) aboard a Long March 6 rocket and entered its preset orbit.

The satellite will be primarily used for the calibration of ground-based radar equipment and radar cross section (RCS) measurement. It will support imaging experiments for ground-based optical equipment and monitoring tests of the low-orbit space environment, while also providing services for atmospheric space environment measurement and orbital prediction model correction.

The launch marks the 568th flight mission of the Long March rocket series and China’s 19th orbital launch of 2025.

China could be targeting 100 or more launches in 2025, driven by growing commercial activity, megaconstellation projects, and new launcher development. A number of new, medium-lift and potentially reusable rockets are targeting debut flights this year.

Highlight missions will include the Shenzhou-20 and 21 human spaceflight missions to Tiangong Space Station. The Tianwen-2 near-Earth asteroid sample return mission is expected to launch from Xichang on a Long March 3B rocket around May.

Launch Startup Deep Blue Aerospace Nebula-1 Rocket Second Stage Vacuum Engine “Thunder RV” Integrated Test

无标题1.webp

On February 22, 2025, Deep Blue Aerospace successfully conducted the second 340-second full-system test of its self-developed "Thunder RV" liquid oxygen kerosene vacuum engine, designed for the second stage of the Nebula-1 rocket, at the liquid rocket engine testing facility in Jinan, Shandong.

During the 340‑second test run, the maximum temperature at the thrust chamber’s outlet reached 1100 K. Over 285 seconds of dynamic vector precision control, 135 oscillations were executed with rapid and stable responses, and the oscillation servo actuation delay did not exceed 0.03 seconds.

This test validated the rationality and reliability of the engine design.

Since you announced your entry into this forum a good 8 months after it was launched with a stink it's safe to conclude you didn't utilize all that time you had productively , by seeking treatment for your condition, did you Skywalker?

How long do you propose to spam this forum? And do you or your employer the MSS plan on contributing to host this forum for all the spamming you're subjecting it to?

Shenzhou-19 astronauts complete third spacewalk, install final debris shielding on Tiangong

07A58997-437A-4CF5-9991-54DC986C6358.webp

HELSINKI — A pair of Chinese astronauts embarked on an extravehicular activity outside the Tiangong space station Friday, as the crew approaches the end of their six-month-long stay in orbit.

Astronauts Cai Xuzhe and Song Lingdong returned to the Wentian science module at 8:50 a.m. Eastern (1250 UTC) March 21, completing their seven-hour extravehicular activity (EVA). Cai initially opened the Wentian hatch at 1:45 a.m. (0545 UT), according to China’s human spaceflight agency, CMSA.

Cai and Song installed space debris protective shielding to the outside of the Wentian module, completing the deployment of shielding carried out across a series of missions and EVAs. The pair also installed extravehicular auxiliary facilities and conducted inspection of extravehicular equipment and systems. The latter task included Cai riding Tiangong’s robotic arm to the specific points on the space station’s exterior, conducting photographic inspections.

Wang Haoze, China’s first woman space engineer and the third member of the crew, assisted operations from inside the Tiangong space station, as she had done for the mission’s previous two EVAs. The first EVA, in December 2024, set an apparent world record for spacewalk duration at 9 hours 6 minutes. Cai Xuzhe has now completed five EVAs, more than any other Chinese astronaut.

“The astronauts performed exceptionally well during the extravehicular mission. First, all of our operations were successful on the first attempt, and the alignment and installation of devices were very precise. In fact, the astronauts completed the tasks even faster than we had anticipated,” Wang Yanlei, a staff member with the Beijing-based China Astronaut Research and Training Center, told China Central Television (CCTV) following the EVA.

“The coordination between the astronauts, as well as between the space station and the ground team, was seamless,” Wang said.

The trio now have just over a month remaining aboard Tiangong, according to CMSA, having arrived at Tiangong Oct. 29 last year. Over the past five months, the crew has conducted a variety of space science experiments and technology demonstrations, including fruit fly cultivation, experiments on protein crystallization, and studies on five types of cells.

Mission activities included materials science, carrying out a number of metal and non-metal experiments in Tiangong’s containerless experiment and high temperature scientific experiment cabinets.

“By leveraging the different experimental conditions of China’s space station and the International Space Station, we conduct scientific research in related fields in a complementary manner, enabling deeper and more extensive space exploration,” Wang Yifeng, an engineer at the Technology and Engineering Centre for Space Utilization, Chinese Academy of Sciences, told CCTV.

The Shenzhou-19 mission has also established a new health assessment system for astronauts in a microgravity environment. The system tracks key physiological and psychological indicators, including cardiac health, bone density, muscle mass and emotional well-being. The system also integrates traditional Chinese and Western medicine.

The crew have also been assisted by Xiao Hang (“Little Space”), a small AI robot equipped with human-robot interaction software to support mission operations.

Crews and backups for the following Shenzhou-20 and -21 missions—which will be China’s 15th and 16th crewed spaceflight missions overall—have been selected, according to Chinese space officials. Neither the identities of the crews nor the timing of the missions have been announced. Each mission will last around six months. During crew handovers, Tiangong briefly hosts six astronauts for several days.

The Long March 2F rocket to launch the Shenzhou-21 mission in the second half of 2025 set off via train for Jiuquan Satellite Launch Centre, northwest China, March 18, after assembly and testing by the China Academy of Launch Vehicle Technology (CALT) in Beijing. The rocket will be kept in a near-ready state to enable a rapid-response rescue launch if needed. The Long March 2F (Y20) and Shenzhou-20 spacecraft have been on standby for an emergency launch since the launch of Shenzhou-19, as a matter of standard practice.
