Chinese scientists exchange huge research data via global high-speed net
Posted by Xiao Qiang | Oct 31, 2005 Researchers from the Chinese Academy of Sciences (CAS) Institute of High EnergyPhysics exchanged huge scientific data with their Italian counterparts via the Global Ring Network for Advanced Applications Development (Gloriad).
The huge data, collected at the Yangbajing Observatory for space radials, could not be transmitted through the prevailing Internet.
The Hong Kong Open Exchange Portal (HKOEP) witnessed such a kind of huge data transmission in the past year.

Two small Chinese satellites designed to detect gamma-ray bursts associated with gravitational waves launched Wednesday on a Long March 11 rocket, beginning an astrophysics research mission to study black holes and neutron stars.
The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor, or GECAM, mission was developed by the Chinese Academy of Sciences on a rapid timeline of a little more than two years.

The Daya Bay Reactor Neutrino Experiment collaboration - which made a precise measurement of an important neutrino property eight years ago, setting the stage for a new round of experiments and discoveries about these hard-to-study particles - has finished taking data. Though the experiment is formally shutting down, the collaboration will continue to analyze its complete dataset to improve upon the precision of findings based on earlier measurements.
Chinese Long March 11 lofts GECAM mission
December 9, 2020
On Wednesday, China launched a double satellite mission intended for research in electromagnetic counterparts of gravitational waves. The launch took place from the Xichang Satellite Center, Sichuan province, at 20:15 UTC using a Long March-11 – Chang Zheng-11 – launch vehicle.
According to the National Space Science Center under the Chinese Academy of Sciences (CAS), the Gravitational Wave High-energy Electromagnetic Counterpart All-Sky Monitor (GECAM) mission is composed of two small satellites, and it will focus on detecting electromagnetic counterparts of gravitational waves, high-energy radiation from fast radio bursts, various gamma-ray bursts, and magnetar flares.
The mission will help scientists unravel the mysteries of compact objects, such as neutron stars and black holes, as well as the merger of binary compact objects.

The China National Space Administration’s Chang’e-5 mission, set to return Moon rocks to Earth next week, has grabbed headlines around the world. But China’s other space agency, the science-focused National Space Science Center (NSSC) of the Chinese Academy of Sciences (CAS), is making news of its own: Just after 4 a.m. local time today it launched its Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) from the Xichang Satellite Launch Center in Sichuan province.
