Combo of rocket, Mengtian lab module rolls out to launch pad, set to lift off

dule, and the Mengtian will be hosting in-orbit experiments dedicated to physics and material sciences, while the Wentian focused more on biological and space life sciences.

Also, the Mengtian will carry the world's first space-based set of cold atomic clocks consisting of a hydrogen clock, a rubidium clock and an optical clock.

"If successful, the cold atomic clocks will form the most precise time and frequency system in space, which should not lose one second in hundreds of millions of years," said Zhang Wei, director of the Utilization Development Center of Technology and Engineering Center for Space Utilization under the Chinese Academy of Sciences.

The world's first cold atomic clock that operates in space was made by Chinese scientists. It was launched with the Tiangong-2 space lab in 2016, and has a margin of error of less than one second in 30 million years.

Now, through ground-based experiments, Chinese scientists he developed cold atomic clocks that are far more accurate than the Tiangong-2 version, according to Zhang.

The development of space cold atomic clock technology will contribute to higher-precision satellite positioning and nigation, and support fundamental physics research such as dark matter probes and gritational we detection, scientists explained.

The Global Times learned from mission insiders on Tuesday that the Mengtian module will be docking with the Tianhe core module at the front after being launched.

With 274 space launches over the past decade and great advances in various space sectors, China has become a strong space power, Wu Yansheng, a delegate to the 20th National Congress of the Communist Party of China, who is the chairman of the China Aerospace Science and Technology Corp, said on Saturday after the conclusion of the Congress.

With 2022 marking the 30th anniversary of the establishment of the country's manned space engineering project, the completion of Tiangong is a key target of the three-step strategy for the project, and an important symbol of China becoming a strong space power in the world, space watchers said.

China's Tiangong Space Station will become the true international space station with the real purpose and practice of openness, as we he been constantly inviting global partners including those from developing countries and European countries to come onboard, in forms such as foreign astronauts' joint flights or experiment payloads to be installed in the space station, Song Zhongping, a space observer and TV commentator, told the Global Times on Tuesday.

The successful launch of Mengtian and its following rendezvous and docking with the space station combination would offer a perfect period for the in-orbit building and assembly stage for the China Space Station, and henceforth the space station would become fully operational with two space labs, space observers said.

The completion of building of the space station will be a milestone in China's space technology development and drive all-around development for a variety of fundamental industries and stimulate new applications such as space breeding and new materials, Song added.
