Shenzhou-11 docks with Tiangong-2 space lab

More than 40 hours after lift-off, the Shenzhou-11 spacecraft has docked with the Tiangong-2 space lab. Astronauts Jing Haipeng and Chen Dong have moved into what will be their home in space for the next month.

Shenzhou-11 spacecraft docks with Tiangong-2 space lab


The Shenzhou-11 manned spacecraft successfully completed its automated docking with the orbiting Tiangong-2 space lab at 3:31 am Wednesday Beijing Time, according to Beijing Aerospace Control Center (BACC).

Shenzhou-11, which was launched Monday morning from northwest China's Gobi Desert, began to approach Tiangong-2 automatically at 1:11 am Wednesday and made contact with the space lab at 3:24 am.

The rendezvous took place in the orbit about 393 kilometers above Earth.

The two astronauts aboard Shenzhou-11, Jing Haipeng and Chen Dong, monitored and reported on the docking operation, relaying their findings to the control center.

According to the mission schedule, once they enter the space module, the astronauts will stay there for 30 days.

Shenzhou-11, China's sixth manned spacecraft, will undertake the longest-ever space mission in the country. The two astronauts will spend a total of 33 days in space.

Sun Jun, deputy chief engineer of BACC, told Xinhua that the precision needed for the orbit prediction and automated docking calculation was much higher than previous docking missions.

China is the third country, after the United States and Russia, to complete successfully space rendezvous and docking procedures.

Tiangong-2 was sent into space on Sept. 15. It is hailed as China's first space lab "in the strict sense" and a key step in building a permanent space station, which the country aims to accomplish by 2020.

China launches manned spacecraft


China launched the Shenzhou XI manned spacecraft on Monday morning to transport two astronauts to the Tiangong II space laboratory.

The spacecraft was sent skyward at 7:30 am atop a Long March 2F rocket from the Jiuquan Satellite Launch Center in Northwest China. It is carrying two male astronauts – 49-year-old Jing Haipeng and 37-year-old Chen Dong.

After the launch, the spacecraft will travel two days before docking with the Tiangong II, which was lifted from the Jiuquan center in mid-September. Then the astronauts will enter the space lab and stay there for 30 days, which will be the longest space stay by Chinese astronauts.

The core tasks of the Shenzhou XI mission are to test rendezvous and docking technologies for the country's planned space station, to verify the life-support capability of the spacecraft-space lab combination as well as conduct scientific research and test engineering experiments, according to Wu Ping, deputy director of the China Manned Space Agency.

Prior to the Shenzhou XI, China had sent five spacecraft and 10 astronauts to space since 2003, when it lifted the Shenzhou V to carry the nation's first astronaut Yang Liwei, who is now a senior space official, into space.

China is the third country in the world that has independently fulfilled manned spaceflight following the former Soviet Union and the United States.

China's manned space program, a source of national pride, aims to place a permanent manned space station, which will consist of three parts — a core module attached to two labs, each weighing about 20 metric tons —into service around 2022, according to the manned space agency.

Lab shows early results

After being launched into orbit on Sept 15, the scientific applications of the Tiangong II space laboratory have been tested and have returned data. Here are some of the results:

The cold atomic space clock, the first of its kind in space, has carried out several tests with stable results, as expected. Scientists believe that such a clock can help to synchronize other atomic clocks more precisely, and that the technological development will create more possibilities for further explorations in space.

The multi-angle wide-spectral imager has captured a range of information on oceans and land as well as changes to clouds, aerosols and water.

The stereoscopic microwave altimeter has applied interference image technology to observe sea surfaces, parts of the Yellow River, the Taklimakan Desert, lakes on the Tibetan Plateau and the Lancang-Mekong River.

An agricultural experiment has sprouted seeds of Arabidopsis thaliana, a small flowering plant, and rice. Samples will be cultivated in space and carried back to the Earth by astronauts.

The space-Earth quantum key distribution and laser communications experiment has established stable connections between the space lab and ground stations.


China to enhance space capabilities with launch of Shenzhou-11


Monday's successful launch of the Shenzhou-11 spacecraft is another step forward to put China among leading players in space technology, said Alexander Zheleznyakov, a Russian expert on history of space flights.

The craft with two astronauts aboard is planned to dock with China's second experimental space lab Tiangong-2 launched in mid-September.

The move marked China's latest effort in a couple of months toward a space power, after successes in the maiden flight of its new generation carrier rocket Long March-7 in June, and the launch of the world's first quantum satellite "Micius" in August, among other developments.

China's achievements and programs in space missions, in particular the lunar exploration program that is well planned and steadily advanced with achievable goals, are impressive and admirable, said Zheleznyakov, who is also member of the Tsiolkovsky Russian Academy of Cosmonautics.

He thought that qualities of the Tiangong-2 space lab indicate the way how China would build its planned space station, which is similar to that of the International Space Station, by gradually docking other space modules with the basic cabin.

Zheleznyakov believed that China's experimental space lab will help provide solutions for spacecraft of different functions to approach and dock, and for a long-term operation of life support system, among others, in order to increase both the safety of astronauts and the service life span of the space station.

He expected to see a node module at China's future space station with multiple docking ports, compared to the only one currently at the Tiangong-2.

The Russian expert added that manned space missions can help push the development of other industries, especially high-tech ones, as space projects involve new materials, advanced application programs and innovative technical solutions, including cutting-edge results in many areas.

Igor Lisov, a prominent Russian space expert and an editor at the industry magazine Cosmonautics News, also spoke highly of China's steady progress in its manned spaceflight programs.

With the achievements made, China can now test technologies for cargo spacecraft docking, life support system operation and water recycling, among others, so as to ensure a long-term continuous operation of its space station in future with less dependance on replenishment from the Earth, he said.

Sergey Zhukov, a test cosmonaut and president of the Moscow Space Club,said it will be the right choice for China to build a space station on the basis of the cylinder structure of the Tiangong-2 space lab.

On the prospects of China's space station, Zhukov believed that advances in technology would likely turn future space station into a terminal to enable manned space missions further beyond as well as stopovers of spacecraft such as mooncraft for maintenance and cargo relays.

Broader space cooperation between Russia and China will benefit each other, he added. Xinhua

The future of the space race



https://youtu.be/1Tsvb1t8908

The history of the space race goes back as early as the 1960s. Back then, the former Soviet Union and the United States were competing for the power of technological superiority.

But now, China has made it a 3-way race, with all three countries developing their respective space programs. However, the three countries are all headed in different directions, as each space program has its own aims and priorities.

Let's take a closer look at what the future of the space race could look like.

The space race of the 1960's between the former Soviet Union and the United States was about power, bragging rights which nation was technologically superior.

Today, the space race is well, maybe a brisk walk. And the three major space faring nations the U.S., China and Russia appear at this point, headed in different directions. So where are the big three going

Since the Shuttle Atlantis landed back at the Kennedy Space Center five years ago, the U.S. has not had the capability to put humans in space. You heard me right.

The U.S. relies on the Russians, at a cost of 65 million dollars a seat, to carry its astronauts to and from the International Space Station. That could change by 2018 when private companies Boeing and Space X should have vehicles ready to ferry astronauts.

With these Station missions turned over to private companies, NASA, the U.S. space agency is now concentrating on building a massive new rocket and a spacecraft, Orion, to carry astronauts first to an asteroid rendezvous and then Mars in the 2030s. Some U.S. partners would like to see a moon mission as a stepping stone to Mars. But NASA rarely uses the moon and Mars in the same sentence.

China on the other hand seems destined and determined to send humans to the moon.

Methodically and in measured steps, China is building toward a permanent presence in space. The Tiangong 2 Space Lab with improved living quarters and life support will be home to two Chinese astronauts for at least thirty days conducting experiments in physics, biology and space medicine.

A mission to put a lander on the moon's dark side is in the works for 2018. And a permanent space station could be in orbit by the early 2020s. All are precursors to landing its astronauts on the moon.

Russia would like to go to the moon too. But the country's struggling economy has forced a tightening of the space budget. Plans for a powerful new rocket that would take cosmonauts to the moon is delayed. But the Russians are still planning a sample return mission in the 2020's and eyeing a 2030 lunar landing. A morale boost could come this week.

A joint Russia-European Space Agency probe is scheduled to deploy a rover to the Martian surface. Russia's last successful planetary probe was in 1984. One unanswered question is whether Russia and United States will go their separate ways if the International Space Station's mission ends as planned in 2024 or continue to play in the same sandbox.

What happens in the future with the big three space powers will likely come down to politics as it usually does. Outside of cooperation in space, the U.S.-Russia relationship is strained and that may well spill over into space relations.

China was never a part of the space station family of nations. And, the U.S. congress forbids NASA from cooperating with China. So, China has been going it alone quite nicely. But nobody is getting along very well. It is possible that by the middle of the next decade, all three will be going their own ways and perhaps all in different directions.

China to launch Shenzhou-11 manned spacecraft on Oct 17


The Shenzhou-11 manned spacecraft will be launched at 7:30 a.m. Monday Beijing Time, China's manned space program spokesperson said Sunday.

The spaceship will take two male astronauts Jing Haipeng and Chen Dong into space, said Wu Ping, deputy director of China's manned space engineering office, at a press conference at the Jiuquan Satellite Launch Center.

The mission will be carried out with a Long March-2F carrier rocket, Wu said.

The spacecraft will dock with orbiting space lab Tiangong-2 within two days, and the astronauts will stay in the space lab for 30 days, she said.

After that the Shenzhou-11 spaceship will separate with Tiangong-2 and return to Earth within one day, Wu said.

The mission aims to transport personnel and materials between Earth and Tiangong-2, and examine rendezvous, docking and return technologies.

During the mission, the spacecraft will form a complex with Tiangong-2. The complex's capabilities of supporting astronauts' life, work and health, and astronauts' abilities for carrying out flight missions will be tested, Wu said.

Other objectives include conducting aerospace medical experiments, space science experiments and in-orbit maintenance with human participation, along with activities to popularize scientific knowledge, she added.

Several technical alterations have been made to Shenzhou-11, though its main functions and technical parameters remain basically the same with Shenzhou-10, Wu said.

To meet the needs of this mission, the orbit control strategy and flight procedures have been adjusted to adapt Shenzhou-11 to the change of the rendezvous, docking and return orbit from 343 kilometers to 393 kilometers from Earth.

The layout of cargo loading has been adjusted to enhance transportation capabilities for the mission.

To further improve the spacecraft's reliability and astronauts' safety, wide-beam relay telecommunications devices have been equipped, which will significantly expand the scope of telemetry, tracking and control, as well as improve the space-ground communication support capabilities when the posture of the spacecraft is changing rapidly.

To verify future space technologies and meet the demand for prolonging the service life of rendezvous, telemetry and tracking devices in future space stations, such devices in Shenzhou-11 have been upgraded, according to Wu.

Certain technical alterations have also been made to the carrier rocket, she said. - Xinhua
