For the team lineup, the Shenzhou-16 for the first time includes a payload expert, Gui Haichao, along with flight engineer Zhu Yangzhu that will be led by veteran taikonaut Jing Haipeng, whose trip marks his fourth time in space. Jing will serve as the mission commander.
This is China's first time including a space engineer and a payload specialist as part of a Shenzhou crew. According to China Manned Space Agency, the space engineer's job will mainly focus on ensuring the normal operation of the spacecraft, performing necessary maintenance and inspection of spacecraft systems and equipment, including executing space walks.
While for payload specialist Gui Haichao, who has attracted the most public attention as the only non-career taikonaut to enter space, he will be responsible for managing and operating scientific researches and experimental projects in the space station, focusing mainly on the management and operation of payload.
During their mission, the Shenzhou-16 crew will continue to conduct extravehicular activities and cargo airlock extravehicular tasks, space science experiments, and the trial of new technology. The mission will also include platform management, taikonaut support system tests, and science education activities, the Global Times learned from China Aerospace Science and Technology Corporation (CASC).
This is the first manned space mission at the space station's application and development phase, and also the first radial rendezvous and docking performed under the T-structure formed by the three modules.
Compared with previous radial docking practices executed by the Shenzhou-13 and Shenzhou-14 spacecraft during the construction stage of the space station, the maneuver for this time will represent a more complex challenge, given the larger combination mass and size, and more intricate aerodynamic effects, the CASC revealed.
Specifically, with the successive joining of more modules and spacecraft including the extra-large Wentian and Mengtian lab modules, as well as manned and cargo spaceships, the space station's size, mass, inertia, and center of gravity have changed significantly, impacting the attitude control of docking vehicles, with some parameters even increasing by orders of magnitude.
Previously when the Shenzhou-14 manned spacecraft docked radially with the space station, it weighed only 47 tons. Now, the Shenzhou-16 will face a 90-ton space station complex with crew onboard.
Therefore, the Shenzhou-16 will use a relative attitude and position control manner, especially for close-range docking. The changes in motion characteristics of the space station will directly affect the spacecraft's rendezvous and docking control process.
As for the launch vehicle, deputy chief designer of the Long March-2F carrier rocket Liu Feng told the Global Times that they have made over 20 technical adjustments to improve rocket performance.
The development team has focused on improving redundancy and equipment advancement to continuously enhance the reliability of the rocket, Liu said, noting that the team has promoted the localization of various electrical system components on the rocket so as to further improve the level of independent control of the product.
The team also used digital and information technology to empower the rocket and introduced "intelligence" into data interpretation.
With the construction of remote measurement and launch support system, developers have achieved real-time communication of test data for the Long March-2F rocket, so that ground control personnel can more easily and comprehensively receive relevant data from the rocket, and carry out real-time monitoring and analysis meanwhile displaying it on the shared screen simultaneously.

China on Monday unveiled the line-up of three taikonauts for Shenzhou-15 manned spaceflight mission that is set to be launched on Tuesday night. The trio led by mission commander Fei Junlong with two space newcomers Deng Qingming and Zhang Lu are going to conduct a direct handover in orbit with the Shenzhou-14 crew at the China Space Station in construction, which shall mark a first in China's aerospace history.
The upcoming Shenzhou-15 crewed spaceflight mission is not only the anchor-leg launch mission at the China Space Station construction stage, but also is the first one to embark on the next operational stage, Fei, the 57-year-old veteran taikonaut who visited the space as the mission commander in the China's Shenzhou-6 mission in 2005, remarked at a press conference on Monday at the Jiuquan Satellite Space Launch Center in Northwest China's Gansu Province.
The crew will carry out more experiments in orbit, operate, maintain and repair relevant equipment and above all execute even more challenging extravehicular activities, or known as spacewalks, with more complicated paths to take on, Fei said on Monday.
The Shenzhou-15 crew has undergone great amount of specific training, which made them very confident to deliver all the set goals and to successfully complete their space run, Fei said.
Deng Qingming, 56, is among the first batch of taikonauts trained in China that includes the country's first astronaut Yang Liwei and also his mission commander Fei in the Shenzhou-15 mission. He has served as a backup for nearly 25 years, in missions such as the Shenzhou-9 and 10, but never got the chance to fly. This will be his first time ever in space.
Zhang Lu, 46, also a new face, was selected in the second batch of taikonauts trained in China in 2010.
Mission insiders told the Global Times on Monday that the two crews of six taikonauts will carry out the space station handover in a face-to-face manner for the first time in the country's manned space history and that is not only of symbolic significance but also carries great practical values to the overall development of the country's first permanent space outpost.
Sources with China's astronaut training system, told the Global Times on Monday that such feat would enable the predecessor Shenzhou-14 to introduce and share what their work and life would be like inside the space station with the new Shenzhou-15 crew directly, boosting the continuity and efficiency of the handover.
It would also help save the resources to set the space station combo from occupied state to unoccupied one and then back again. And the handover will be more target-oriented, especially for those ongoing experiments and space station maintenance work, the sources said.
Having six taikonauts simultaneously onboard the China Space Station in construction, would also verify its performance under the full load condition, which would lay groundwork for future tasks where more payload technicians are needed for more complicated experiments, Song Zhongping, a space watcher and TV commentator, told the Global Times.
By plan, the handover will last for a week or so, and after that, Shenzhou-14 crew will return to the Dongfeng landing site on Earth.
As the temperature drops to somewhere near minus 20 C in Jiuquan around this time of the year, the launch of Shenzhou-15, which is via a Long March-2F rocket from the Jiuquan center, also faces a special challenge of extremely low temperature.
According to the China Academy of Launch Vehicle Technology (CALT), the developer of the Long March-2F rocket, Shenzhou spacecraft had only been launched twice in unscrewed condition during the Shenzhou-1 and 4 missions in late November. Shenzhou-15 would be first one to be carried out with taikonauts onboard in the cold weather.
However, the CALT explained that they have taken such unique challenge into consideration. They have also confirmed the two sets of the temperature system inside the rocket's nose cone, to make sure that the temperature of the propellant of the return and propelling module meets the launch condition.
