Ah sticking to the Chinese proverb " Those that say it can’t be done should get out of the way of those getting it done."

NASA: New "impossible" engine works, could change space travel forever

NASA: New "impossible" engine works, could change space travel forever
Until yesterday, every physicist was laughing at this engine and its inventor, Roger Shawyer. It's called the EmDrive and everyone said it was impossible because it goes against classical mechanics. But the fact is that the quantum vacuum plasma thruster works and scientists can't explain why.

Shawyer's engine is extremely light and simple. It provides a thrust by "bouncing microwaves around in a closed container." The microwaves are generated using electricity that can be provided by solar energy. No propellant is necessary, which means that this thrusters can work forever unless a hardware failure occurs. If real, this would be a major breakthrough in space propulsion technology.

Obviously, the entire thing sounded preposterous to everyone. In theory, this thing shouldn't work at all. So people laughed and laughed and ignored him. Everyone except a team of Chinese scientists. They built one in 2009 and it worked: They were able to produce 720 millinewton, which is reportedly enough to build a satellite thruster. And still, nobody else believed it.

Now, American scientist Guido Fetta and a team at NASA Eagleworks—the advanced propulsion skunkworks led by Dr Harold "Sonny" White at the Johnson Space Center—have published a new paper that demonstrates that a similar engine working on the same principles does indeed produce thrust. Their model, however, produces much less thrust—just 30 to 50 micronewtons. But it works, which is amazing on its own. They haven't explained why their engine works, but it does work:

Test results indicate that the RF resonant cavity thruster design, which is unique as an electric propulsion device, is producing a force that is not attributable to any classical electromagnetic phenomenon and therefore is potentially demonstrating an interaction with the quantum vacuum virtual plasma.

The entire idea that we have found something that seems to go against the the principle of conservation of momentum just seems crazy to me. But the fact that it has worked for two independent parties can't be denied. That's the laboratory speaking. Then again, perhaps both labs made a mistake. I'm sure this will be tested by the Russians and the Europeans too, but at least I'm glad we are working on it.

But the fact that we may be witnessing something completely new, something that may push us forward into sci-fi territory once again, is very exciting.

There's another story out there, I think it was a War is Boring article, completely paranoid on why the Chinese are keeping the Tiangong in orbit and not directing it to burn in the atmosphere. This article here is completely reasonable on why the Tiangong is still operational. If you're planning a manned space station for the first time, you want to know what could happen in the long run. The article filled with paranoia didn't even speculate what the Tiangong was doing except point out what the US maybe being doing already. So how's that justify paranoia unless the US was engage in nefarious operations in space?

Russian space program will switch from American to Chinese made electronic components.

Chinese microelectronics will replace U.S. microelectronics in Russian space, defense industries

Russian rocket and space and defense enterprises plan to buy batches of electronic components from China worth some $1 billion in the next calendar year, the newspaper Izvestia reported on Wednesday.

"We are working with the China Aerospace Science and Industry Corporation [CASIC]. The institutions comprising it have already provided us with several dozens of items that are either a direct alternative, or have slight alterations, of those elements that we cannot buy due to the sanctions imposed by the U.S.," a source close to Roscosmos told Izvestia.

The technical documentation is now being translated and the products are being tested to determine if they meet the stated characteristics in terms of susceptibility to temperatures, vibration and impact of heavy charged particles, the source said.

Russia plans to buy several billion dollars worth of such products from China in the next 2-2.5 years, until the Russia industry begins manufacturing electronic components of the necessary nominals in the space (radiation-resistant components) and military (for use in military systems) categories.

Representatives of 12 institutes developing and manufacturing electronic components in the CASIC structure will arrive in Moscow on August 18 to take part in a specialized seminar for Russian manufacturers, the source said. A similar seminar will later be conducted in St. Petersburg, the source said.

"The seminar is organized in cooperation with Roscosmos, the company Reshetnikov Information Satellite Systems, and the St. Petersburg firm Epsilon, which has recently received official partner status from a company conducting foreign economic activities in CASIC," the source said.

Reshetnikov Information Satellite Systems has confirmed the information on the upcoming visit by the Chinese delegation and the preparations for a seminar.

The office of the United Rocket and Space Corporation has expressed an interest in the development of cooperation with China.

"The corporation is ready to work with all manufacturers of electronic components who can make competitive offers in terms of quality, supply time and price. Possible cooperation with China is especially vital in connection with the sanctions that have been imposed," Igor Burenkov, information policies director at the United Rocket and Space Corporation, told Izvestia.

According to Izvestia, Russian companies purchased some $2 billion worth of electronic components from the U.S. annually before summer 2013. The Americans turned a blind eye to the supply of electronic components for Russian dual-purpose goods. The relations aggravated after Russia refused to extradite Edward Snowden. After that scandal, the U.S. refused to sell Reshetnikov Information Satellite Systems elements for the spacecraft Geo-IK-2. Now, the billions may go to Chinese manufacturers.

However, the source told Izvestia Russian companies are currently not getting refusals from European suppliers of electronic components.

"The Europeans are currently supplying everything without problems, with the exception of digital analog transformers. The purchase of digital analog transformers requires a special license from a European authority. However, there are no problems with that either, we are buying European products, including from ST Microelectronics, a leading European producer of electronic components," the source said.

Andrei Ionin, a leading analyst with Glonass, said he believes the establishment of large-scale cooperation with Chinese manufacturers may become the first step towards the formation of a technological alliance with the BRICS countries.

I doubt it, there is no prototype yet ... and CZ-5 can only be launched from Wenchang Satellite Launch Center which is not ready yet until early 2015

Has this been reported by other, more reputable outlets? Epoch times ain't exactly known for its truthfulness.

Cool, mankind is one step closer to going back to landing a human being on the moon again.:eek:

Beijing (AFP) - China will launch its first recoverable moon orbiter later this year, the government announced, in the latest step in its ambitious space programme.

The mission will be launched before the end of the year and will travel to the moon before returning to earth, the State Administration of Science, Technology and Industry for National Defence (SASTIND) said in a statement on Sunday.

Doing so will require withstanding the high temperatures that develop when a probe re-enters the Earth's atmosphere.

The orbiter will test technology that will be be used for China's ambitious Chang'e-5 mission, which aims to gather samples from the moon's surface, the official Xinhua news agency reported.

Beijing sees its multi-billion-dollar space programme as a marker of its rising global stature and mounting technical expertise, as well as evidence of the ruling Communist Party's success in turning around the fortunes of the once poverty-stricken nation.

The moon orbiter has been transported to the Xichang Satellite Launch Centre in the southwestern province of Sichuan, SASTIND said.

China had declared that mission a "complete success", but mechanical problems have plagued Yutu and reports in May said the rover was gradually becoming "weakened".

The Chang'e-5 mission will be more sophisticated and technological challenges include taking off from the moon's surface, rendezvous and docking in lunar orbit, and high-speed Earth re-entry, Xinhua said.

The military-run project has plans for a permanent orbiting station by 2020 and eventually to send a human to the moon.

A chief scientist told state media in 2012 that China planned to collect samples from the surface of Mars by 2030.
