Generation born in the '80s plays an important role in nation's space industry

Dressed in his favorite red No 24 jersey with a basketball in hand, people cannot believe 28-year-old Li Wen is an engineer for the Shenzhou IX spacecraft at the Jiuquan Satellite Launch Center.

Besides being called a space engineer, the gentle young man from the Inner Mongolia autonomous region prefers people call him "the Kobe in aerospace city".

Los Angeles Lakers' All-Star guard Kobe Bryant is his favorite basketball player.

Li is just one of thousands of young space engineers in China who devoted themselves to the country's aerospace industry and witnessed the successful launch of the Shenzhou IX on Saturday.

Chinese space engineers are about 15 years younger on average than the average age of the space engineers in other countries, China Central Television reported.

The busy young engineers staring at the big screen and cheering the country's first manned space docking at the Beijing Aerospace Control Center on Monday illustrates that the generation of Chinese born in the 1980s is playing an important role in the aerospace industry.

Liu Ning, 32, director-designer of the China Academy of Space Technology, is the head of the technology department of the Tiangong-1 lab module, and through a simulation has experienced almost all of the activities that astronauts might perform in a module during a space mission.

Liu has even experienced a simulated weightless environment, and was hung upside down from a crane to test whether astronauts would be able to open a door in a weightless environment.

Liu served as a training partner for the three astronauts in the Shenzhou IX spacecraft in October to familiarize them with every button and function in the Tiangong-1 module.

When the Tiangong-1 module was launched, Liu felt a sense of loss.

Unlike Liu, 34-year-old Lu Xinguang, director-designer of the Beijing Aerospace Automatic Control Institute, felt relieved after every successful launch. He has already attended the launch of Shenzhou V, Shenzhou VI, Shenzhou VII, Shenzhou VIII, Shenzhou IX and Tiangong-1 module.

Lu told China Central Television that it felt really good to see the spacecraft flying into the sky.

The booming development and proud feeling of being a space engineer has attracted young people's attention.

Shang Teng, 25, a new researcher at the Beijing Aerospace Automatic Control Institute, told China Central Television that he is very excited to have the opportunity to learn from these young engineers.

"Everyone here loves what he or she is doing. It is the right place for me," Shang said.

In China's space development, the 1980s generation of engineers and scientists are playing an important role.

Mou Yu, 30, deputy director-designer of the China Academy of Launch Vehicle Technology, said it is time for the 1980s generation to contribute to social development. Mou is confident of taking on any challenge.

"Young space engineers and scientists are the hope for the development of China's aerospace science and technology," said Yang Hong, director-designer of the China Aerospace Science and Technology Corporation.

On Saturday, China successfully launched the Shenzhou IX, and on Monday the country's first manned space docking was completed, taking China one step closer to setting up its own space station by 2020.

This morning at 6:18 local time, a turning maneuver of 180° has been successfully performed. TG-1 is now behind. For the second manual docking and unlike the first automatic docking, it's Shenzhou-9 which will receive TG-1, hence the turning maneuver.

The Long March 5 will comprise a hydrogen-fueled core using two YF-77 engines in the first stage and a variable number of boosters, each with twin YF-100s. The design has been controversial in China because in its maximum configuration, it will have 10 engines firing at liftoff, presenting an elevated risk of launch failure. Chinese engineers have proposed that a larger, single engine be developed to replace the YF-100, even though it has not entered service.

10 engines to achieve 25t to LEO? China needs to build more powerful engines.

"No matter whether it is for the manned spaceflight project or the communication system for tracking, telemetry and command (TT&C), the launching of the Shenzhou IX spacecraft marks a new milestone." said Qian Weiping, chief designer of the TT&C communication system of the manned spaceflight project, on June 17, 2012 during an interview.

"The mission should examine whether the TT&C communication system can meet the requirements of fully supporting future space station and space activities."
said Qian Weiping.

Qian Weiping told the reporters that the land, sea and space-based integrated architecture of the TT&C communication system took initial shape through the Shenzhou VIII mission, and the manned Shenzhou IX spacecraft will further examine and consolidate the system through optimization, making it an excellent one that can permanently support China's manned space activities.

The reporter learnt from the Meteorology, Hydrology and Space Weather Center of the General Staff Headquarters (GSH) of the Chinese People's Liberation Army (PLA) that a new-generation numerical weather forecast system independently researched and developed by China will serve the launching and recovery of the Shenzhou IX spacecraft, which is also the first time for the new-generation numerical weather forecast system to serve a manned space flight project.

With the most advanced technology, the highest resolution and the longest period of validity among China's numerical weather forecast systems, the new-generation numerical weather forecast system has the functions of using global meteorological observation data and issuing mid-term global weather forecast. Its period of validity has increased from five days to eight days and its support capability on refinement and accuracy has also been markedly improved.

The new-generation numerical weather forecast system passed the appraisal in December 2011. Wang Yegui, head of the expert panel on Shenzhou IX spacecraft meteorological support and chief engineer of the Meteorology, Hydrology and Space Weather Center of the GSH of the PLA, held that the new system will play an important role at critical junctures such as rocket fueling, launching and recovery of the spacecraft and manned rendezvous and docking.

Chinese experts can't fully explain the two glowing unidentified flying objects which appeared to be rushing at high speed toward Shenzhou-9 spacecraft shortly after its launch on Saturday.However, one did raise the possibility that it could just have been two moths flying in front of a camera lens.

It has been confirmed that the objects were recorded by one infrared video camera monitoring the launch and were spotted on a screen at a control center in Beijing about four minutes after the Long March-2F rocket had blasted off from the Jiuquan Satellite Launch Center in northwest China's Gansu Province.

The rocket had just shed its nose cone when they were seen heading toward the rocket before flying past and vanishing two seconds later.

Many television viewers saw the objects during a live broadcast on state TV.

"They couldn't be planes, meteors, birds or separated parts from the rocket," Wang Sichao, an astronomer and UFO expert at the Nanjing Purple Mountain Observatory of the Chinese Academy of Sciences, said in an early assessment. However, later he conceded that were two possibilities. They could be two moths flying dozens of meters away past the camera lens. And they also might have been planes, if the rocket had flown past the no-fly zone by the time the two objects were captured.

"If the two objects, emitting light, had been detected at different locations, they could have been UFOs," Wang told China News Service. "But (we) haven't received a similar report at another location yet."

Wang ruled out spots on the camera lens or meteors.

He said the video would be kept in the archives for further research.The Shenzhou-9 spacecraft took off from the launch site in the Gobi Desert at 6:37pm on Saturday.

A video of the launch featuring the two flying objects was posted on Weibo and by Tuesday afternoon had received more than 2,000 comments.

Many people said the objects might have been planes flying beside the rocket or parts of the rocket itself.

Wang said they couldn't be rocket parts as they were flying in the wrong direction - toward, not away from, the rocket. Planes were a distant possibility early in the launch because there were air traffic restrictions in place around the launch site.

An astronomy expert in Shanghai said the infrared video shot from a single spot offered too little information to identify the objects.
"We need the videos from at least two cameras from different angles to work out the precise position and speed of the objects and then to identify what they were,"
said Tang Haiming, an official with the Shanghai Astronomical Observatory on Sheshan Hill.

Last August, a huge glowing object was spotted high above Shanghai, Beijing and other regions in China by several civil aviation pilots, sparking debate among astronomers.

Some said the object was an aircraft beyond human technology after studying pictures and calculating its flight path.

The Shenzhou-9 and its crew of three, flight leader Jing Haipeng, 45, Liu Wang, 43, and China's first female astronaut Liu Yang, 33, successfully linked up with the Tiangong-1 space lab on Monday.

n addition to the largest difference of being a manned spacecraft, the Shenzhou-9 is also different with the Shenzhou-8 in the following aspects when it rendezvous and docks with the Tiangong-1.

They rendezvous and dock in different directions


The Shenzhou-8 unmanned spacecraft rendezvous and docks from behind twice, namely the spacecraft catches up with and docks with the space lab module Tiangong-1 from behind and then it retreats 140 meters to make the second docking with the Tiangong-1. However, the Shenzhou-9 docks with Tiangong-1 from the front. The Tiangong-1 catches up with Shenzhou-9 and the Shenzhou-9 automatically separates and retreats 400 meters to make the second docking with the front of Tiangong-1.

The methods of rendezvous and docking are different


The rendezvous and docking between Shenzhou-8 and Tiangong-1 is automatic under the guide of the rendezvous and docking equipment on the spacecraft while that between Shenzhou-9 and Tiangong-1 is not only automatic but also uses the manual control to testify the manually controlled rendezvous and docking technology of astronauts.

Actually, the manual control of a spacecraft is equipped on the spacecraft from Shenzhou-1 to Shenzhou-8 but astronauts had never had an actual operation in previous space travel, namely the astronauts only sat in the cabin but did not drive the spacecraft. It will be the first time for the astronauts of Shenzhou-9 to manually control the spacecraft and make rendezvous and docking to personally experience the feeling of driving it.


The environment of rendezvous and docking is different

As the Shenzhou-8 will make its first space rendezvous and docking, it was designed to start automatic rendezvous and docking in sunshine area but come to the shadow area after finishing the rendezvous and docking so as to reduce the interference caused by the light waves while the Shenzhou-9 makes rendezvous and docking in full sunshine area.

As the light waves in the space will interfere with the measuring equipment, the rendezvous and docking of Shenzhou-9 is more difficult than that of Shenzhou-8 and it will be a severe test for the rendezvous and docking equipment.

From two spacecraft to an integrated whole

The rendezvous and docking between the Shenzhou-8 and Tiangong-1 only completes a rigid connection between the two but the cabin doors connecting the two spacecraft do not open. Therefore, they are not a real integrated whole in terms of the inner environment of the cabin.

The astronauts of the Shenzhou-9 will enter in the Tiantong-1 to work and live as an integrated whole, therefore the cabin doors of the two spacecraft will open. The Shenzhou-9 will be the first to connect with Tiangong-1 and they will become two connected rooms running in space. The astronauts will walk through the Shenzhou-9 and enter the Tiangong-1 to live and work. Thus, the environmental control and life support equipment including the carbon dioxide purification device and microbial control device will be opened to provide working and living environment similar to that on the earth.
