China builds nuclear-powered deep-sea station

Not content with ambitious plans to dominate space exploration over the coming decades, China is also looking to master the ocean with the development of a deep-sea station which could be its first step towards large-scale underwater mining.


Plans for the nuclear powered mobile deep-sea station were unveiled earlier this year by China Ship Scientific Research Centre – the state-owned venture whose Jiaolong manned submersible recently reached depths of over 7,000 metres – according to South China Morning Post.

The craft would have dimensions of 60.2m x 15.8m x 9.7m, weigh about 2,600 tonnes, and have enough room for 33 crew members.

It would have propellers to move submarine-like underwater and several ports to allow smaller craft to dock with it, the report said.

On that note, a smaller prototype which could carry 12 crew on an 18-day expedition is currently in production, with an expected delivery date of 2015.

While China’s plans in space appear to revolve heavily around military strategy, its deep sea efforts have more to do with the country finding an answer to its current energy problems.

Drilling for oil and mining copper and other natural resources both appear to be high on the list of China’s deep-sea priorities, although technological limitations may hold back advances in the project for some time, the report claims.

When China wants something it usually succeeds in the end, however, so it would not be out of the question to see the launch of a full-sized deep-sea station by 2030, according to SCMP.

As with most elements of Chinese technology innovation, the PLA is never too far away – this deep-sea project is apparently funded by 863 Program, a hi-tech state scheme.

China plans nuclear deep-sea mining base


A Chinese company is set to build a nuclear-powered mobile deep-sea station in the western Pacific, according to local reports.

The China Ship Scientific Research Centre's proposed station -- which will have huge propellers to enable free movement in the ocean depths -- will be manned by 33 crew for up to two months at a time and powered by a nuclear reactor.

Its main goal, according to reports in the South China Sea Post, will be to mine for precious metals. The nation, which recently announced it is stockpiling rare earth elements amid fears of shortages, would use the facilities to hunt mainly for copper, lead, zinc, silver, gold and oil.

Underwater mining is typically a costly affair, full of potential dangers and problems. Canadian-owned Nautilus Minerals Inc was the first commercial copper-gold mining venture to be granted permission to explore the Bismarck Sea floor surrounding Papua New Guinea, but has already run into problems with environmentalists warning the mining could destroy marine life and cause devastating oil spills. China's Tongling Non-ferrous Metals Group had signed up as the project's very first customer in April 2012, but a dispute with Papua New Guinea also stands to halt the mining project's 2013 launch completely

The Chinese company appears to be wary of these issues, and is therefore treading carefully, with plans for the bold venture slated for a more reasonable 2030 launch -- according to experts the South China Sea Post spoke to -- and a smaller 12-crew prototype capable of 18-day dives set to launch by 2015. The larger 60-metre-long craft will weigh in at 2,600 tonnes.

In preparation, the China Ship Scientific Research Centre has been engaging in test dives of manned vehicles -- its Jiaolong model reached a record-breaking 7,020 metres at the Mariana Trench in the Pacific Ocean on the same day that China's Shenzhou-9 spacecraft docked at the Tiangong 1 space station.

Reports suggest that the project is being funded by the state's 863 Program, a fund specifically for the development of innovative technologies, which has links with the military. Nevertheless, mining for oil and copper seem to be the most likely priorities on the agenda, with crew on the station able to spend two months at a time living and mining underwater.

Shanghai is hosting the 41st Underwater Mining Institute conference October 2012, and further details could potentially be revealed then. In the meantime, a look at the China Ship Scientific Research Centre's website reveals fields of interest that range from manned submersibles such as the Jiaolong vessel to atmospheric one-man diving suits and autonomous underwater robots -- the latter would be exponentially beneficial in aiding aquanauts during danger-filled underwater mining missions.

The centre also appears to be keen on waterslides. Definitely one to watch.

JIUQUAN, Gansu, June 9 (Xinhua) -- China will launch its Shenzhou-9 manned spacecraft sometime in mid-June to perform the country's first manned space docking mission with the orbiting Tiangong-1 space lab module, a spokesperson said here Saturday.

By 10:30 a.m. Saturday, the spacecraft and its carrier rocket, the Long March-2F, had been moved to the launch platform at the Jiuquan Satellite Launch Center in northwest China, a spokesperson with the country's manned space program said.

In the next few days, scientists will conduct functional tests on the spacecraft and the rocket, as well as joint tests on selected astronauts, spacecraft, rocket and ground systems, according to the spokesperson.

The Shenzhou-9 will be launched into space to perform China's first manned space docking mission with the orbiting Tiangong-1 space lab module.

The manned spacecraft Shenzhou-9 and its carrier rocket were delivered to the Jiuquan Satellite Launch Center in early April this year.

The Tiangong-1, or Heavenly Palace-1, was lowered to docking orbit in early June and is orbiting normally, the spokesperson said.

The final preparations are running smoothly, and the selected astronauts have completed their training and are in sound physical and mental conditions, according to the spokesperson.

Niu Hongguang, deputy commander-in-chief of the country's manned space program, said earlier that the three-person crew on Shenzhou-9 might include female astronauts, but the final selection would be decided "on the very last condition."

The space docking mission will be manually conducted by astronauts, giving China another chance to test its docking technology, the program's spokesperson said previously.

One of the three Shenzhou-9 crew members will not board the Tiangong-1 space module lab, but will remain inside the spacecraft as a precautionary measure in case of emergency, the spokesperson said.

The target module Tiangong-1, which blasted off on Sept. 29, 2011, went into long-term operation in space awaiting docking attempts of Shenzhou-9 and Shenzhou-10 after completing China's first space docking mission with the unmanned Shenzhou-8 spacecraft in early November.

China has announced it will carry out a manned space flight at some point in the middle of June.

A rocket carrying the Shenzhou 9 spacecraft has been moved to a launch pad in the north-west of the country.

According to state news agency Xinhua, it will carry three astronauts - possibly including a woman - to the Taingong 1 space station module.

This will be China's fourth manned space flight and its first since 2008.

It became only the third country to independently send a man into space in 2003.

Stellar plans
 
Last year, China completed a complicated space docking manoeuvre when an unmanned craft docked with the Taingong 1, or "Heavenly Body", by remote control.

The astronauts onboard the Shenzhou 9 spacecraft will also dock with the Taingong 1 - an experimental module currently orbiting Earth - and carry out scientific experiments on board.

Xinhua reported that Niu Hongguang, deputy commander-in-chief of China's manned space programme, said the crew "might include female astronauts".

The mission is part of China's programme to develop a full orbiting space station.

Beijing is planning to complete the 60-tonne manned space station by 2020.

China was previously turned away from the International Space Station, a much bigger project run by 16 nations, reportedly after objections from the United States.- BBC

China will launch its first manned mission to an orbiting space laboratory in mid-June, according to state media reports and the country's human spaceflight agency.

A Long March 2F rocket will launch three astronauts aboard a Shenzhou 9 capsule for China's first manned space docking at the mini-space station Tiangong-1. The space lab module has been circling Earth unmanned since its launch last year.

"The Shenzhou 9 will perform our country's first manned space docking mission with the orbiting Tiangong 1 space lab module," the Xinhua news agency quoted Zhou Jianping, chief designer of China's manned space program, as saying today (June 9).

Zhou's comments came as he accompanied the rocket set to launch the Shenzhou 9 mission to a pad at China's Jiuquan Satellite Launch Center in the country's northwest region.

The mission, Zhou told Xinhua, will be a major milestone for China's space exploration program.

"It means China's spacecraft will become a genuine manned shuttle tool between space and Earth. It can send human beings to space stations or space labs," Zhou told Xinhua. "This will be a significant step in China's manned space flight history."  [Gallery: Tiangong 1, China's First Space Lab]



China's Shenzhou 9 mission will mark the fourth human spaceflight for the country, which has been making steady advances since the launch of Chinese astronaut Yang Liwei in 2003 on Shenzhou 5, the country's first human spaceflight. China is the third country to achieve human spaceflight after Russia and the United States.

Since its first flight, China has launched two more manned missions, the two-man Shenzhou 6 flight and three-person Shenzhou 7 mission. Last September, China launched the Tiangong 1 module — a prototype for a future space station — into orbit. That launch was followed in November by the unmanned Shenzhou 8 mission, which successfully docked a capsule with the space laboratory twice during the test flight.

The Shenzhou 9 mission will mark China's first human spaceflight to an orbiting module. Earlier this year, space program officials said the mission could also mark the first launch of China's first female astronaut, but a final decision on that is pending, Xinhua reported.

A translation of an announcement released online by the China Manned Space Engineering Office (CMSE), which oversees China's human spaceflight program, stated that preparations of both the rocket and Shenzhou 9 astronaut crew are going smoothly.

A series of spacecraft and rocket tests, as well as final mission training, are underway ahead of the planned spaceflight, CMSE officials said.

China's Shenzhou (or "Divine Vessel") spacecraft are three-module space capsules with a design originally based on Russia's Soyuz space capsules, but the Chinese vehicles carry substantial modifications.

Like the Soyuz, Shenzhou vehicles carry up to three astronauts and consist of a propulsion module, a crew capsule and an orbital module. But unlike Russia's Soyuz, the orbital module of Shenzhou spacecraft carries its own solar arrays and can remain in space after its crew returns to Earth in the crew capsule.

China's Tiangong 1 ("Heavenly Palace 1") space laboratory module, meanwhile, is a prototype space station designed to test the technologies required for a much larger space station complex currently under development. The Tiangong 1 module is 34 feet long (10.4 meters), 11 feet wide (3.35 m) and weighed about 8.5 metric tons.

Chinese space officials have said the country is developing a larger, 60-ton space station that will consist of several modules. That space station is slated to be launched in 2020.

China is currently following a three-step space exploration program that ultimately aims to land an astronaut on the moon. According to a white paper released by the Chinese government in December, the country plans to launch a series of robotic moon landers and a lunar sample-return mission by 2016.
