Nice write up on the QC news about China’s QC satellite from late Wed.

China’s Quantum Science Satellite was declared operational this week after five months of in-orbit testing, now set for a busy two-year mission demonstrating hack-proof communications by means of entangled photons as a trailblazer for what is widely considered the communications technology of the future.

The Quantum Science Satellite, nicknamed Mozi, was launched into orbit on August 15, 2016 as the world’s first dedicated quantum communications testbed, embarking on an ambitious mission dedicated to validating the principles of quantum communications across vast distances of open space.

Enlarge Image Singapore’s Nanyang Technological University has successfully launched a satellite from the International Space Station (ISS) for the first time. It’s a nanosatellite that deserves special attention for its new thruster technology. These new micro-thrusters allow the satellite to remain in for space twice as long as other similar satellites, according to the university. The improved thrusters could go a long way towards fighting the problem of space debris: Man-made trash such as the old satellites and spent rocket stages that create a field of debris around the earth.

QC communications (includes networking) is now available in China.

Nice job China; now if the rest of us can catch up.

China’s quantum communication satellite, launched last August, is officially operational after four months of in-orbit testing, the Chinese Academy of Sciences (CAS) said Wednesday.

Testing of the satellite, payloads and space-ground links have been completed, the CAS said, adding that everything was operating properly.

Hope folks are realizing this is happening and now real. Not sure what experiments their doing as they have already been experimenting already on hacking.

The world’s first quantum science and communications satellite has been handed over to Chinese scientists for the official start of experiments to test the phenomena of quantum entanglement and ‘unhackable’ quantum communication.

The Quantum Experiments at Space Scale (QUESS) satellite was launched on August 15 last year and soon after began testing its payloads and space-to-ground links.

“The in-orbit test came to a very successful end,” said mission designer and leader Pan Jianwei, an academic at the Chinese Academy of Sciences (CAS) which oversees the institutions involved in the mission.

Entrepreneur’s Space X agency files request for $10bn project with the FCC and says internet speeds globally will reach 1Gb/s.

The man who wants to take humans to Mars also wants to connect the whole of planet Earth and bring digital equality across the globe.

Elon Musk’s Space X spacial agency has requested to the US Federal Communications Commission (FCC) authorisation to launch 4,425 satellites which would be used to provide connectivity to the more than 7.2 billion humans on Earth.

The US Defense Advanced Research Projects Agency (DARPA) officially handed off control of the Space Surveillance Telescope (SST) to the US Air Force Space Command. After five years of successful operation the telescope will now be dismantled and sent overseas.

Australian forces are planned to handle the task of scanning the skies for asteroids that could endanger satellites or potentially strike the Earth. The Air Force will maintain “a broad and full SST partnership” with the Australian military, said 1st Lt. Sarah Burnett, a spokeswoman for Air Force Space Command (AFSPC). After the move, SST will operate as a dedicated sensor in the US Space Surveillance Network, operated by AFSPC.

Hmmm; there is another use for this type of satellite just can’t openly state.

SHANGHAI—China launched a satellite to monitor its greenhouse gas emissions early on Thursday, the latest step in efforts to cut its carbon footprint, the official Xinhua news agency said.

The launch follows the United States joining China in formally ratifying the Paris agreement to curb climate-warming emissions. It also comes as large sections of northern China have been shrouded in near-record levels of air pollution for most of the past week, disrupting flights, closing factories and schools, and forcing authorities to issue red alerts.

China launched the satellite via a Long March-2D rocket from Jiuquan Satellite Launch Center in the northwestern Gobi Desert, Xinhua said.

Scientists with the China Academy of Space Technology (CAST) claim NASA’s results ‘re-confirm’ what they’d already achieved, and have plans to implement it in satellites ‘as quickly as possible.’ China claims they’ve created a working prototype of the ‘impossible’ reactionless engine – and they say they’re already testing it in orbit aboard the Tiangong-2 space laboratory. The radical, fuel-free EmDrive recently stirred up controversy after a paper published by a team of NASA researchers appeared to show they’d successfully built the technology.

The implications for this could be huge. For instance, current satellites could be half the size they are today without the need to carry fuel.

At a press conference in Beijing, researchers with CAST confirmed the government has been funding research into the technology since 2010, and claimed they’ve developed a device that’s already being tested in low-Earth orbit, IBTimes UK reports. It comes just a month after anonymous sources told IBTimes UK that tests on the EmDrive were underway aboard Tiangong-2 shown below.
