Hainan island new sub-orbital launch pad
2015/11/04
Completion of new launch pad in Hainan province, Danzhou City, for sub-orbital small and medium sounding rockets with altitude up to 300 km. Will mainly be used in space environment sciences and space weather.

China new space robot Xiaotian
2015/11/05
After the scaled model of China's Mars orbiter and lander, China Aerospace Science and Technology Corporation disclosed on the occasion of the 17th China International Industry Fair opened in Shanghai, its first space robot. Called Xiaotian (小天) meaning Little Celestial, it is designed to cope with harsh space environment and complex operational tasks, encountered on the future space station, manned moon landing, in-orbit servicing, space exploration and other unmanned missions.
Differing from conventional industrial robot is its ability to deal with harsh space environment: zero gravity, high-vacuum, high temperature, space radiation environment and other characteristics, where industrial robots would face serious loss of functions, unable to effectively assist astronauts in orbital operation.

Yang Liwei discloses worst moments from SZ-5 mission: I saw cracks on both portholes becoming larger!
2010/3/27
I thought that I was going to be martyred
At 9:00 on October 15, 2003 the entire rocket tail roared loudly, starting to burn hundreds of tons of high-energy fuel, eight engines spewing red-hot flame, high temperature gas emission taking only a few seconds to vaporize thousands of tons of water. The total weight of the rocket and the spacecraft reached 487 tons.
At the beginning the spacecraft's rise was very smooth; slowly rising, even smoother than an elevator. I realized later that the spacecraft takeoff acceleration is a gradual process.
As the rocket gradually accelerated, I felt the pressure gradually increasing. Because of this, we had to bear such load during training, so my body was feeling quite good.
But as the rocket reached the altitude of thirty or forty kilometers, the rocket and the spacecraft began shake sharply, producing resonances. As a result I endured great physical pain.
The human body is very sensitive to low frequency vibrations below 10 Hz, it will make people's body enter resonance mode. And then the problem is not only the low-frequency vibration, as this new vibrations were superimposed on a 6G load.
This superposition was terrible, as we never conducted such training. I started to worry, thinking that this would end in a serious situation.
Resonance follows a variation curve, thus making the pain more and more awful, I feared my internal organs would be ripped apart, it was almost unbearable. I felt dying.
Slowly, the resonance slowed after 26 seconds. Once freed from that uncomfortable state, I started to feel relaxed and more comfortable, like a rebirth. But in extreme pain, for just a short instant, I really thought I'll be martyred.
After the flight back I described in detail the painful process. Our researchers team believed that the spacecraft's main resonance vibrations were generated from the rocket. After taking corrective design, the problem was solved. Shenzhou-6 and Shenzhou-7 no longer endured this problem.
Thrilling way home
At 4:31 on October 16, 2003, I received the order to initiate the return procedure from the Beijing Aerospace Command and Control Center.
5:35, the spacecraft began to decelerate on the 343 km high orbit. First the spacecraft had to make a 180 attitude adjustment. I felt the ship sustained deceleration, close to the direction of the Earth.
6:04, the spacecraft reached 100 kilometers altitude, entering into the dense atmosphere. Then the spacecraft's encountered great air resistance, it is a sharp slowdown, resulting in a nearly 4G overload, my chest and back were under great pressure. We have been trained to cope with this situation.
But then the situation became very tense: as the right porthole began to crack. I was aware that outside the temperature would reach 1600 to 1800 degrees Celsius.
Then I suddenly remembered the American Columbia space shuttle accident. As hot gases entering from a small crack lead to the total desintegration of the shuttle. Now, that a porthole is broken, I would certainly suffer the same fate!
As the right porthole's crack enlarged to half the size of the porthole, I turned my head to look at the left porthole. It began also to crack.
After coming back to the ground, I was informed that it was the anti-burn coating layer that cracked, and not the window itself. Both portholes craked at different time because the anti-burn coating layers were different for each porthole.
"He said that Yang Liwei’s face was full of blood when he opened the door on the capsule. Later, the blood was wiped out and photos were retaken."
Right side of lower lips clearly showing traces of fresh injuries
