with the Shenzhou VIII smooth transitions, and the Temple of God eight launch countdown has entered the stage of docking. Recently, a former China’s manned space project applications received Commander of the British scientist Hou Tencent micro-interviews, the Shenzhou VIII spacecraft docking with the target aircraft and other Temple One hot topic of space to answer.
are selecting women astronauts
friends “less Bin”: how many astronauts weight for good? How much is good? How old is better? What special requirements?
Hou Ying: astronaut selection criteria is: 160 – 172 cm tall, is now extended to 175 cm; weight 50 to 70 kg; mental state to be very good, for example, Yang Liwei, the Shenzhou heart rate per minute Only 65 under. There is a, practical ability stronger. The selection of our female astronaut, is great. Astronaut’s age is generally 30 to 40 years old.
friends, “Wang Qi”: what year the International Space Station, retire a few years the world is not only run our space station?
Hou Ying: The International Space Station and 10 years, that is, only to retire in 2020. United States now hopes to extend its life made to 2027, or longer. Anyway, in 2020 we will be successful launch of China’s space station, then we will become the world’s only space station.
high-thrust rocket development in Tianjin
broken throat: the construction of our launch site in Hainan, Hainan by typhoons frequently, have no effect on the base ?
Hou Ying: out now for the future space station, Wenchang County in Hainan to build a fourth launch site, which is facing the sea while the low-latitude emission. Climate would be affected, but we will choose the launch. Still have a lot of good weather.
Hou English: Why should it launch base in Hainan? Because in the future we want to build the space station to launch Chang E IV, need high-thrust rocket, the rocket thrust is not enough now, so we want to establish the Long March V, thrust up to 25 tons. But it’s rocket is five meters in diameter, and now all of our rockets are 3.25 m in diameter, the other three launch site because of the track can not be brought into question. Now that we developed in Tianjin Long March V, in the future can be transported by boat to Hainan, passage.
Fengxian Biao: The United States uses the most recent space launch 77-ton high-thrust rocket, and is developing a large 144-ton thrust rocket. What China is now the largest rocket thrust is how much? Is there a greater thrust in the development?
Hou Ying: The United States has not reached the 144-ton level until 2017 to reach this level. Their shuttle can load 30 tons. China is now the biggest load force is tonight with the Long March 2F-T1, can reach 8.6 tons. After 2013, China will have to load 25-ton Long March V, Chang E address space station and launch problems.share:
