Ten years after China sent its first man into low earth orbit, three astronauts operating the Shenzhou-10 spacecraft started a journey on a mission which seeks a permanent space station around 2020.
Chinese President Xi Jinping said at the launch site that the crew carry a "space dream" of the Chinese nation and represent the lofty aspirations of the Chinese people to explore space.
The dream, though also dreamt by the more frequent space travelers of Russia and American, includes a manned space station, moon exploration and even deep space odysseys.
The dream is a humble one. China was decades behind Russia and the United States in space technology.
But Chinese pursue it unswervingly in line with a carefully designed three-phase manned space program.
Two years after the space flight operated by China's first astronaut, Yang Liwei, two men, including Shenzhou-10 commander Nie Haisheng, orbited the earth in 2005. Then three more in 2008, two of whom finished China's first extra-vehicular activities (EVA).
After the unmanned Shenzhou-8 and Tiangong-1 space module docking in 2011 to test automated space docking, a key skill to assemble a space station, three Chinese astronauts succeeded in operating the docking manually in 2012.
The Shenzhou-10 mission, if successful, marks the end of the first half of the second phase, which means China has completely mastered EVA and space docking skills.
However, just as the female astronaut Wang Yaping said, "we are all students in facing the vast universe."
China's pursuit of its own space dream showcases a latecomer's unremitting interests and desire to learn about the universe.
During the 15-day Shenzhou-10 mission, Wang will hold a class in space educating a group of students from a high school in Beijing through satellite communication.
This in-orbit event, hopefully broadcast live, will inspire students and also spur citizen's space interests in a country with 1.3-billion people, making this an unparalleled popularization of science in human history.
Similar to other space giants, China's space program was carried out by astronauts selected from air force pilots and supported by military resources. But China has reaffirmed that it opposes militarization of the space and will utilize the space in a peaceful way.
After the year 2020, China's future space station will probably be the only one of any kind in service considering the ISS's retirement plan. By then, China's space dream will not only serve its own people but also contribute to space exploration for the human race.

China's space dream crystallized with Shenzhou-10 launch
JIUQUAN, June 11 (Xinhua) -- China successfully launched its fifth manned spacecraft late Tuesday afternoon, sending three astronauts on the country's longest space trip.
With 10 astronauts and six spacecraft launched into space in a decade, China is speeding up on the path of exploration and building a home for Chinese in the galaxy.
At a see-off ceremony held hours before the launch, Chinese President Xi Jinping extended good wishes to the three astronauts.
"The mission's crew members carry a space dream of the Chinese nation, and represent the lofty aspirations of the Chinese people to explore space," said Xi.
The President later watched the launch at the Jiuquan Satellite Launch Center in northwest China, and shook hands with staff at the center after the successful launch.
Unlike the space trip of Yang Liwei, China's first astronaut who boarded the Shenzhou-5 spacecraft in 2003, of less than a day, the three astronauts will stay for half a month.
In its journey, Shenzhou-10 will dock with the orbiting space lab Tiangong-1 twice, once through automatic operation and the other manual, and a lecture will for the first time be given on board the assembled orbiter to a group of teenage students on the ground.
Compared with the previous nine Shenzhou spacecraft, the Shenzhou-10 is no longer experimental but considered an applicable shuttle system for transporting astronauts and supplies to orbiting modules.
"It is like developing a new type of car. You have to try it on roads of different conditions. Now trials are over and the car can be put into formal operation," said Zhou Jianping, chief engineer of China's manned space program.
On the other hand, the upgraded Long March-2F carrier rocket is technically the same as the one used with the Shenzhou-9 manned spacecraft.
"No alteration means that China's rocket technology is becoming mature," said Jing Muchun, chief designer of the carrier rocket.
This mission aims to further test technologies designed for docking and supporting astronauts' stay in space, as well as to use new technologies related to the construction of a space station, said Wu Ping, China's manned space program spokeswoman, at a press conference on Monday.
The Tiangong-1 space lab has been in orbit for about 620 days, and about three months are left before the designated end of its service.
The module is considered the first step toward China operating a permanent space station around 2020 and making it the world's third country to do so.
The nation is likely to launch a space station before 2016.
There are risks that the conditions of some components on Tiangong-1 might not be at their best since the module is near the end of its service and has gone through four docking tests, Wu said.
For Nie Haisheng, commander of the three-member crew and a second-time space traveler, this mission will be longer, with more experiments to be conducted, than his previous outing in 2006.
"It will be a new challenge with greater risks," Nie told the media on Monday.
However, he is looking forward to entering the space lab module. "My colleagues and I will work in a home for Chinese in space," he said.
For this mission, the manned space program also considered approaching the public.
In a lecture through a live video feed system, female astronaut Wang Yaping will introduce motion in a microgravity environment, surface tension of liquid, and help students understand weight, mass and Newton's Laws.
Wang will also interact with students and teachers on Earth and the lecture will be broadcast live.
Ordinary Chinese, especially science enthusiasts, are excited about the new mission.
"It is a festival for space fans," said Zhao Yang, a researcher with the China Science and Technology Museum, who just watched the Hollywood sci-fi blockbuster Star Trek Into Darkness on Monday.
He was very much interested in the lecture to be given in space, saying, "There might be an interesting introduction about the weightless condition."
For renowned science fiction novelist Liu Xinci, Tuesday's events reinforced his belief that he will live to see space travel become accessible for all common people.
He has a very vivid vision of future life.
"In the next century, human beings will set foot on all planets in the solar system. People will inhabit the moon and Mars. A lot of people will work in space as space journeys will be as easy as flights."
COMMUNISTS IN SPACE
The three-member crew were all veteran Air Force pilots before being selected as astronauts. Nie is the first general visiting space while his teammate Wang Yaping is China's first space traveler born in the 1980s, a generation growing up in era of reform and opening up.
All of them are members of the Communist Party of China.
Yang Liwei, the country's first astronaut, once told Xinhua that Chinese astronauts might not pray like their foreign counterparts do before they set off on a space mission; however, Communism, as their shared faith, supports them.
"If the country has its own space station, Chinese astronauts, who are Party members, might set up a Party branch up there," Yang said.
Of the crew, 48-year-old Nie is commander of this mission, and responsible for the manual docking operation with the Tiangong-1 target orbiter.
Zhang Xiaoguang, 47, will assist the commander to accomplish the spacecraft's manual docking with Tiangong-1. Another job that Zhang will be doing in space is to film Wang's lecture lecture, which will be broadcast to middle and elementary school students in China.
Wang, 33, is the second Chinese female astronaut after Liu Yang in the Shenzhou-9 mission, which blasted off in June last year. Wang will be responsible for monitoring the conditions of the spacecraft, space experiments, operation of equipment and taking care of fellow crew members.- Xinhua

Chinese Astronauts return to Earth safely; Success on road to deep space!
Module re-entry process: Shenzhou-9’s journey back to earth CCTV News - CNTV English.
After thirteen days in space, the astronauts aboard the Shenzhou-9 spaceship will return to the Earth.
The first stage of the process is for the re-entry module to separate from the orbital capsule.
The propulsion module will later separate from the re-entry module, after it’s propelled it to a lower altitude of 140 kilometers. The re-entry module will then adjust its position before making its entry into the atmosphere. Well, as we can see, according to accurate calculation, the module is to land at Siziwang Banner, in central Inner Mongolia Autonomous Region.
Let's see this simple illustration. The module will pass through the so-called "black out area". At this stage, communication is impossible, due to high levels of friction with the atmosphere, causing extreme temperatures. When the capsule is out of the black-out area, several parachutes will be released one by one, to gradually slow the module's descent. When the vehicle gets below 10km, the heat shield will be jettisoned. At 1 meter above the ground, 4 small engines will ignite to reduce the speed to a safe range for landing. Once on the ground; the re-entry module will communicate with the control center to show its location, so rescue teams find it as soon as possible.
The completion of the Shenzhou-9 mission will bring China one step closer to building its own fully-fledged space station by 2020. China's permanent space station is expected to weigh about 60 tons, so it require rockets such as Long March 5 rockets to send different parts into space. At the hub of China's future space station will be the Core Module. It will control the station's altitude, propulsion, and life support systems for the astronauts.
At one end of the core module is a small connecting chamber. On each side of this are the two Laboratory Modules. Experiments can be carried out both inside and outside these modules, testing such things as exposure to cosmic rays, a vacuum environment, and solar winds. On the other end of the space station is the cargo delivery module, which will carry supplies, equipment and energy stocks. Back on the other side, attached to the connecting chamber will be the Shenzhou spacecraft which will travel between the space station and the earth. China's space station is an ambitious and complicated structure but it’s still only about one-sixth the size of the International Space Station.
Currently flying at an orbit of around 400 kilometers above the earth is the International Space Station. The US and Russia have led the design and construction of the ISS, with 16 other countries also contributing to the project. China's main contribution to the ISS is the Alpha Magnetic Spectrometer. It is a particle physics experimental instrument designed to search for anti-matter and dark matter. These two mysteries have been puzzling scientists for decades according to theory, they should exist. But so far, no direct evidence has been found. It's planned that the ISS will plunge back into the ocean in 2028.
By that time, if China's space program goes according to plan, China's space complex will then be the only space station orbiting the earth.
The Success on road to space!
BEIJING, June 29 (Xinhua) -- The return of the Shenzhou-9 spacecraft to Earth Friday morning marked the end of a 13-day journey through space for three Chinese astronauts.
But it also marked the beginning of a new journey for China as it inches closer to its goal of building a space station.
China's space program has accomplished in 20 years' time the same tasks that took developed nations nearly half a century to accomplish, including manned space flights, space walks and a manned space docking procedure.
The recent successful docking of the Shenzhou-9 and Tiangong-1 lab module marks a new height for Chinese space exploration, as well as a new leap forward for national rejuvenation.
China's space exploration took a long time to ramp up. In 1992, 43 years after the founding of the People's Republic of China, the country decided to establish its manned space program.
Scientific policies have facilitated the program and helped it develop comprehensively and sustainably. The aerospace industry was given a larger role in the country's 12th Five-Year Plan (2011-2015) and authorities have taken pains to implement every step of the manned space program with great care.
The success of the Shenzhou-9 has demonstrated the power of China's collective wisdom and capability. About 110 research institutions have directly participated in the manned space program thus far, with more than 3,000 institutions and units coordinating their efforts.
The mission has also demonstrated the success of socialism, showing that it has the political advantage of accumulating wisdom and resources to achieve great things.
Facing limitless space, China's space program is only just beginning. The country will face challenges on its road to rejuvenation, but the success of the mission has boosted national confidence and shown China's people that the country's space program will have a bright future.- Xinhuat

Three Chinese astronauts returned to Earth Thursday (June 28) after 13 days in space on a historic mission that made their country only the third nation ever to successfully dock a manned spacecraft to another in orbit.
China's Shenzhou 9 space capsule landed at about10 p.m. EDT (10 a.m. Friday, June 29 Beijing time) in Inner Mongolia, an autonomous region of the People's Republic of China. To prepare for their journey home, the space crew — which included China's first female astronaut Liu Yang — separated the Shenzhou 9 capsule its target, the Tiangong 1 prototype space module, on Wednesday (June 27).
Their landing was broadcast live on China's state-run CCTV television network, showing the capsule streaking through the atmosphere like a meteor, deploying its main parachute, then making the final landing and rolling over on its side in a rough touchdown.
"We fulfilled the first manned manual docking," mission commander Jing Haipeng told CCTV reporters after exiting the Shenzhou 9 capsule. His comments in Chinese were translated into English by CCTV. "For the country and people all across the country, thank you for your concerns." [Photos of China's Shenzhou 9 Mission]
Jing and crewmates Liu Yang and Liu Wang appeared to be in good health after their space mission. The trio wore broad smiles and waved to cameras after leaving their spacecraft, but did sit in reclined chairs to help ease their adaptation back to Earth's gravity after nearly two weeks in weightlessness.
Shortly after the landing, China's Premier Wen Jiabao proclaimed the Shenzhou 9 mission a complete success.
"This manned docking mission of Tiangong 1 and Shenzhou 9 marks a large milestone, a major breakthrough for China to master the space docking technology," Wen said while reading a statement. "And also, it marks a decisive step forward on China's second step on its space strategy."

China's big space leap
China's Shenzhou 9 mission, which included successful displays of manual and automatic dockings, represented an important leap forward for China's space program. In addition to being China's longest space mission to date, it also tested technology vital for the country's goal of building space station in orbit by the year 2020.
"Chinese astronauts have their own home in space now," Jing told China's President Hu Jintao on Tuesday (June 26) during a special call according to the state-run Xinhua news agency. "We are proud of our country!"
And while the orbital linkups are important technological achievements for China, the mission also carried a wider social impact because it included the country's first female astronaut: the 33-year-old Liu Yang.
"It was like a home in Tiangong, and I feel very happy and proud of my country," Liu Yang told reporters after landing.
Jing, the commander, is China's first veteran astronaut to fly in space twice. The third crewmember, Liu Wang, served as the Shenzhou 9 docking pilot.
"It feels really good to feel the ground and to be back home," Liu Wang said.
Shenzhou 9 mission, which launched into space on June 16, accomplished China's first manned space docking, after the spacecraft robotically docked to Tiangong 1 on June 18. Several days later, on June 24, the astronauts backed away from the orbiting module and parked their Shenzhou 9 spacecraft once more, demonstrating manual control over the procedure as well.
The successful linkups made China only the third country, after the United States and Russia, to accomplish manned dockings in orbit.
The Shenzhou 9 mission, as well as experiments performed aboard Tiangong 1 throughout the flight, tested technologies that will help China fulfill its goal of building a 60-ton space station in orbit by 2020.
"The data will help us improve technologies for astronauts' future, long-term stays in a space station," said Chen Shanguang, chief commander of the mission's astronaut system, according to Xinhua
China is not a member nation of the $100 billion International Space Station in low-Earth orbit, a roughly 430-ton orbiting outpost that is jointly operated by more than a dozen countries.
But Chinese officials have outlined an ambitious space program for the nation, which includes collecting samples from the moon and robotically returning them to Earth before landing astronauts on the lunar surface.
The Shenzhou 9 mission is China's fourth manned spaceflight. Previous expeditions were launched in 2003, 2005 and 2008.
The Tiangong 1 test module was launched into orbit in September 2011. In November, a robotic spacecraft, called Shenzhou 8, completed the country's first unmanned space docking. According to Chinese officials, Tiangong 1 has performed well, and could play host to another crew in the near future.
"Based on current conditions, the service of Tiangong 1 can be extended," said He Yu, chief commander of the Shenzhou 9 spacecraft, reported Xinhua. "It has consumed less than one-fourth of its fuel and no back-up systems have been used."
Depending on its condition, the module could remain in orbit as China continues its space station construction efforts.
"If Tiangong 1 was in perfect shape, it could work side by side with Tiangong 2, which will be launched in the future," He said.

China's Space Age Grows Up As U.S. Space Race Winds Down
The Russians started the space race back in the 1950s.This picture taken on June 12, 2012 shows Chinese People's Liberation Army (PLA) Air Force fighter pilot Liu Yang (L) together with her two male colleagues, Jing Haipeng (C) and Liu Wang (R), in their spacesuits as they pose for an official photo at the Jiuquan space base, north China's Gansu province. China said on June 15, 2012 that a female astronaut will be among the three-person team on board the Shenzhou-9 spacecraft, and will take off at 6.37 pm (1037 GMT) on June 16 from the Jiuquan space base in the Gobi desert for the country's fourth manned space launch, with Liu Yang, 33, and two male astronauts on board.

The U.S. perfect it with putting a man on the moon, then with a series of modern high tech space shuttle missions and Mars ROVERS. But now, the final frontier captains are more likely to be Russians, with their hopes for a human Mars landing someday, or Chinese, with a new China space station due within the next 8 years.
While the U.S. has basically scrapped its space mission, slashing the budget of NASA and now too close to a fiscal cliff to invest in fly-by-night government funded manned space operations, China is on the move.
The country’s Shenzhou IX spacecraft, carrying two male astronauts and one female astronaut into space this week, completed its first-ever manual docking with the Tiangong I space lab on Sunday. The manual docking of two ships whipping through space ultimately demonstrates China’s grasp of essential space rendezvous and docking know-how. Manual docking requires astronauts to have a precise judgement on the relative distance between Shenzhou IX and the Tiangong-1 module, a challenge to their capability of coordination, accuracy and psychological stability. The astronauts have done more than 1,500 docking simulations on the ground to ensure a successful manual docking.
Their successful completion of the docking mission at 12:47 pm local time on Sunday means China is fully capable of transferring humans and cargo to an orbiter in space much like the Americans, only the Americans have abandoned further work in this area beyond the current International Space Station expedition which ends next month. That current mission is actually being commanded by Oleg Dmitrievich Komonenko, a Russian national born in Turkmenistan. He’s one of three Russians on the Russian Proton vesssel, with two Americans and one astronaut from The Netherlands.
China’s three astronauts boarded Tiangong through Shenzhou IX where they will continued conducting various scientific experiments on the space lab before heading returning.

Three Chinese astronauts manually docked their space capsule at an orbiting module Sunday (June 24), a major first for China's space program and the country's plans to build a large space station.
The astronauts docked their Shenzhou 9 spacecraft with the unmanned Tiangong 1 module 213 miles (343 kilometers) above Earth. It was the second orbital linkup in a week for the two spacecraft, which performed China's first automated space docking June 18.
Shenzhou 9's astronauts Liu Wang, Jing Haipeng and Liu Yang — who is China's first female astronaut — are the fourth Chinese crew to fly in space. The astronauts launched into orbit on June 16, atop a Long March 2F rocket from the Jiuquan Satellite Launch Center in China's northern Gansu province.
Tiangong 1 has been in orbit since September 2011, and was part of China's first robotic docking with the unmanned Shenzhou 8 capsule in November. The Shenzhou 9 crew made their first docking with Tiangong 1 June 18, marking the first time a manned Chinese spacecraft has docked with another vehicle in orbit.

Full video: Shenzhou-9 manually docks with Tiangong-1 CCTV News - CNTV English.
Earlier today, the astronauts undocked the two spacecraft and flew Shenzhou 9 about 1,300 feet (400 meters) away. They then maneuvered their capsule by hand, with Liu Wang at the helm, back into docking configuration with Tiangong 1 at 12:48 p.m. China Standard Time, or 12:48 a.m. EDT (0448 GMT).
"The success of the manual rendezvous and docking mission represents another important phase achievement of the Shenzhou 9 and Tiangong 1 rendezvous and docking mission," Wu Ping, spokeswoman of the China Manned Space Program, said during a press briefing following the docking. "The three astronauts will once again enter the orbiting module of Tiangong 1 to carry out scientific experiments."
The mission's docking maneuvers are a milestone in the development of China's manned space program, which flew its first astronaut in space in 2003. Tiangong 1 (which means "Heavenly Palace" in Chinese) is a prototype for China's first manned space station, which officials say will be functional by 2020.
China is the third country after Russia and the United States to fly astronauts into space.
After today's docking, the Shenzhou 9 astronauts (known as taikonauts) received a message from a group of Chinese oceanauts who are setting records not above the ground but below it.
"We wish for a great success of the manual docking and brilliant achievements in China's manned space and manned deep-sea dive causes," read a message sent by three crewmembers aboard the Chinese submersible Jiaolong, 7,015 meters (23,000 feet) beneath the Pacific Ocean in the Mariana Trench, the deepest spot on Earth, state-run newspaper Xinhua reported.
The oceanaut crew set a new deep-diving record for China on June 22.
Shenzhou 9 and Tiangong 1 are due to stay connected for four more days, with the crew departing June 28 and landing back on Earth June 29.

China marks first manned space docking
China achieved another milestone in its space program as the Shenzhou-9 spacecraft successfully completed its second docking with the Tiangong-1 space lab module by hand. This was China’s first ever manned manual space docking.Ten meters, five meters, three.
It was a moment astronaut Liu Wang had practiced for, more than 1.500 times. And he knew he could do it.

Liu said, "I’m 100% sure of a successfully operation. Because I can’t fail."
Dubbed the "space needle threading" mission, the astronauts had to carefully adjust the craft’s trajectory with very little margin for error.
It all culminated in the historic moment.
Shenzhou-9’s docking ring makes contact with the Tiangong-1 and a tight seal is formed as the connection between the craft is secured.
It was even more accurate than the first automated docking of Shenzhou-9 and Tiangong-1.
The State Council Information office then announced the success of the mission.
Wu Ping, spokeswoman for State Council Information Office said, "I can announce that the first Chinese manned docking of the Shenzhou-9 spacecraft and the Tiangong-1 space lab module has been successfully completed."
A big success, but it’s not over yet.
After the docking, the astronauts entered Tiangong-1 for another four days of experiments.
Following this, they’ll return to Shenzhou-9’s re-entry module, to prepare for the journey back to earth.

China's Jiaolong sets new deep sea dive record
Good news came as the crew of the Jiaolong submersible surpassed the country’s dive record by going deeper than 7,000 meters after a successful test dive in the Pacific Ocean on Sunday morning.
A record breaking moment.
Jiaolong, China’s manned submersible successfully completed a dive of 7,015 meters below sea level at around 11 am local time, 8:55 am Beijing time. It’s the craft’s fourth dive into the Mariana Trench.

The submersible then went on to finally reach a maximum depth of 7,020 meters below sea level.
The three oceanauts sent greetings from the bottom of the deep blue sea to the three astronauts in outer space, who were about to carry out their manual docking of Shenzhou-9 with the orbiting Tiangong-1 lab module.
"We wish the Shenzhou-9 crew success with the manual docking and great achievements for China’s manned space and deep-sea dive missions."
Various samples and video footage have been taken during the deep sea mission to benefit future scientific research.
Jiaolong returned safely on Sunday afternoon.

This file photo, taken in 2011, shows the Chinese submersible 'Jiaolong.' The submersible broke through the 7,000-metre mark in an ocean dive on Sunday, state media said, setting a new national record for China.
A manned Chinese submersible broke through the 7,000-metre mark for a new national record on Sunday, state media said, as the rising Asian nation showed off its technological might.
The dive came on the same day as China was attempting its first manual space docking, a complex manoeuvre that will bring the country a step closer to building a space station.
"This (dive) shows the performance of the submersible is stable," mission chief commander Liu Feng told state television in a live broadcast from aboard the ship supporting the submersible.
"The level of our technical personnel is getting better and better."
The Jiaolong -- named after a dragon from Chinese mythology -- carried three people into the Mariana Trench, the deepest place in the world.
Applause broke out as a depth gauge aboard the supporting ship Xiangyanghong registered more than 7,000 metres, state television showed.
The same submersible reached 5,188 metres in a Pacific dive in July last year. And in a series of three previous dives since June 15, the craft has gone deeper each time. Experts say 7,000 metres is the limit of its design.
Experts say China intends to use the submersible for scientific research, such as collecting samples of undersea life and studying geological structures, as well as future development of mineral resources.
On its third dive on Friday, the crew collected samples of water and sediment and took photos of sea life, Xinhua said.
Scientists say the ocean floors contain rich deposits of potentially valuable minerals, but the extreme depths pose technical difficulties in harvesting them on a large scale.
And the stability and durability of the craft presents further problems for future operations.
The recent round of dives have seen some minor technical glitches, such as the breakdown of communications equipment and problems with the adjustable ballast system, state media has reported.
The 7,000 metre dive was previously scheduled for Monday, state media had reported. The reasons for the change of date were unclear but mean the record-setting dive comes the same day as China's landmark space manoeuvre.
