China's Shenzhou-12 manned spacecraft, Nie Haisheng, Liu Boming and Tang Hongbo, was sent into space by a Long March 2F carrier rocket from Jiuquan Satellite Launch Center at 9:22 am on June 17, 2021.It is the first time in five years that China has sent a man into space. It is also the first time that China has sent a man into space since it entered the era of space station construction in orbit.This is China's 19th manned space mission and the first manned space mission during the space station phase.

Since the first Shenzhou V manned mission was launched in 2003, China's manned space program has made continuous strides in the past 18 years, from one man to many days, from onboard work to space walk, from short-term stay to medium-term stay. Each step of these strides embodies the courage and perseverance of the astronauts in pursuing their dreams.China has contributed its wisdom and strength to mankind's peaceful use of space.The Chinese government has always been committed to the peaceful use of outer space, and has conducted extensive cooperation and exchanges with relevant countries in manned spaceflight in accordance with the principle of "peaceful use, equality, mutual benefit and common development".In the phase of the space station, China will continue to increase the depth and breadth of international cooperation and exchanges, so that the Chinese space station will become a space laboratory for the benefit of all mankind.It is expected that in the near future, Chinese and foreign astronauts will be able to travel to the Heavenly Palace together.

Slip ring is a very important part of radar antenna, which can form electrical energy and signal between rotating part and fixed part of radar and maintain continuous connection.In order to achieve the radar antenna positioning, communication, detection, monitoring and other purposes, to provide a guarantee for the aviation industry.

CENO’S hollow shaft slip ring technology is well established and can be combined with low, medium and high frequency slip rings to form precise hybrid slip rings to meet different environmental requirements.
