Sorry, I meant dominate numerically, even factoring out koreans, chinese make up more than 40% of the student body, especially comp sci and engineering. Be it uwaterloo, or uoft
And yes their are smart and dumb people in every race, we shouldnt generalize

Come to UBC, it's University of Billion Chinese.

China has successfully launched a new-generation telecommunications satellite, the country’s Defense Ministry has announced.

BEIJING (Sputnik) – The launch was carried out at 15:19 GMT on Thursday from the Xichang Satellite Launch Center using the Chang Zheng 3B (CZ-3B, or Long March 3B) carrier rocket, the ministry said. The second Tongxin Jishu Shiyan (TJS) satellite will help test multi-frequency high-speed data transmission.

China plans to carry out about 30 space launches in 2017.

Gaojing-1&2 (SuperView-1&2) - CZ-2D - TSLC, LC9 - December 28, 2016 (03:23 UTC)

SuperView-1 01&02 were successfully launched on one rocket in Taiyuan Satellite Launch Center on 28 December 2016. They provide 0.5 m panchromatic and 2 m multispectral imagery to global users.


The two satellites are working at the normal orbit now. The ground stations have successfully received 1241 scenes of imagery by 11 January 2017. A few of first images are showed as follows:

Buildings of the Potala Palace in Lhasa, Tibet





Tibet Exhibition Center in Lhasa, Tibet




Hong Kong Convention and Exhibition Center, Hong Kong

China's quantum communication satellite delivered for use

BEIJING, Jan. 18 (Xinhua) -- 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.

The Quantum Experiments at Space Scale (QUESS) satellite is the first-ever space-ground test platform for quantum communication, said Wang Jianyu, executive deputy chief engineer of the project.

The research team has begun to carry out experiments and preliminary data has been obtained, said Pan Jianwei, chief scientist on the project.

China successfully launched the world's first quantum satellite from Jiuquan Satellite Launch Center on Aug. 16, 2016.

QUESS will explore "hack-proof" quantum communications by transmitting unhackable keys from space, and provide insight into the strangest phenomenon in quantum physics -- quantum entanglement.

The world's first Quantum communications satellite, Quantum Experiments at Space Scale(QUESS), independently designed and launched by China in August last year, has finished its four-month in-orbit test and was put into service on January 18th, reports ce.cn.

QUESS, nicknamed Mozi after the ancient Chinese philosopher and scientist, aims to facilitate quantum communication between ground stations. Quantum communication possesses ultra-high security as a quantum photon can neither be separated nor duplicated.

Quantum communication will enable China to provide high-level communication security support to areas like islands in the South China Sea, Chinese embassies and consulates in foreign countries, and naval vessels.

Mozi has been selected as one of the ten innovative technologies that changed the world in 2016 by Scientific American, and is the only tech on the list that was developed outside of the United States.

First quantum satellite surpasses expectations

Five space exploration projects to begin during 13th Five-Year Plan

Micius, the world's first quantum satellite, has successfully completed four months of in-orbit tests since China launched it on Aug 16, the Chinese Academy of Sciences has announced.

"The overall performance has been much better than we expected, which will allow us to conduct all our planned experiments using the satellite ahead of schedule and even add some extra ones," Pan Jianwei, chief scientist for the satellite project, said at a ceremony on Wednesday.

The major goal is to test the possibilities of relaying quantum "keys" carried by photons, or light particles, over 500 to 1,200 kilometers from a satellite to ground stations to create a new kind of information transmission network that cannot be hacked without detection.

A similar, but smaller-scale, network has been tested and put into commercial use in recent years on metropolitan and intercity networks in China, but satellite-ground quantum communication is believed to be key to expanding a quantum network's coverage worldwide.

Other missions include quantum teleportation and quantum entanglement, both for the first time in space.

"Initial tests on the satellite have reached a transmission rate that will allow us to finish these experiments within several weeks, so we will have time to add new experiments," Pan said.

He said the plans include more complex quantum tests between Micius and five ground stations across China this year, and then cross-continental quantum communication experiments to establish links with ground stations in Austria, Italy and Canada in 2018.

"Many key technologies we developed for the Micius satellite have never been used or tested, so in our original plan, it would have been a full success if we were able to build the satellite-ground connection. We did not expect the signal would be so strong, and the transmission rate so high," Pan said.

Micius is part of the academy's Strategic Priority Program, which has sent three satellites into space since December 2015.

Late last year, the academy published a proposal for five new space exploration projects to be started during the 13th Five-Year Plan (2016-20).

"The academy's Strategic Priority Program gives scientists a new stage to build a stronger international reputation," said Xiang Libin, vice-president of the Chinese Academy of Sciences. "I just received an email from a famous French scientist who wished to cooperate with us on the new space exploration projects. Without the reputation we have built gradually through the Strategic Priority Program, we would not have attracted such attention."

Luojia-1A satellite built to observe ground light

By Zhao Lei | China Daily

Updated: 2017-02-10 08:07

China has become most lighted nation in Asia, signaling its growth, expert says

China will this year launch the country's first remote-sensing satellite dedicated to observing ground light at night, according to designers.

The Luojia-1A, a 10-kilogram mini satellite, is being developed by scientists at Wuhan University in Hubei province and will carry a highly sensitive night light camera with a 100-meter ground image resolution, Li Deren, chief scientist of the project, told China News Service on Wednesday.

Li, a professor of remote-sensing surveys at the university and an academician of the Chinese Academy of Sciences, said that the satellite will be capable of detecting large lighted structures on the ground within its designated observation area, such as bridges over the Yangtze River. He added that images taken by Luojia-1A will be clearer than those by United States-developed satellites.

Luojia-1A will be used to help economic planners and analysts with their research and to provide data to policymakers when they determine overseas trade measures, Li said.

Wuhan University is also working with China Aerospace Science and Industry Corp to design the Luojia-1B, a remote-sensing radar satellite, and plans to send it into orbit in 2019, the report said.

Pang Zhihao, executive editor-in-chief of Space International magazine, said on Thursday that China now has no satellite that was specifically designed to take night images of ground structures.

"Now we have satellites that have infrared imagers or synthetic aperture radars to obtain images of landscapes or buildings. Compared with them, the Luojia-1A's camera is specifically developed to capture lighted objects at night, so it is very sensitive to light," he said.

Pang added that images and data generated by Luojia satellites will be useful for provincial and city officials to monitor local economies and to improve their development planning.

Li Xi, a researcher at the State Key Laboratory of Information Engineering in Surveying, Mapping and Remote Sensing in Wuhan, who is taking part in the development of Luojia satellites, said the project team has vast experience in researching lighted objects.

Its members have used images of lighted structures in Syria and Iraq to discover refugee movements and changes of battlefields. They have also analyzed the concentrations of lighted structures in Asia over the past 20 years.

The research concluded that China gradually became the most lighted nation of those surveyed, a visual representation of the continuous growth of China's economy, he said.
