China launched a relay satellite on Wednesday morning to lunar orbit to pave the way for the space power's prospective trailblazing (开拓性的) expeditions to the Moon. The Queqiao 2, or Magpie Bridge 2, satellite was lifted...
Queqiao-2 uses highly elliptical lunar frozen orbit which was only about 300 km away from the moon at the closest point. Queqiao, however, orbits around the second Lagrangian (L2) point of the Earth-Moon system, which is about 65,000 km from the moon. The closer distance will make data ...
BEIJING, April 12 (Xinhua) -- The Queqiao-2 satellite has recently completed in-orbit communication tests, with its platform and payloads working normally, according to the China National Space Administration (CNSA) on Friday. The functions and performance of Queqiao-2 meet mission requirements, a...
The launch is only the first step in this mission, as Queqiao 2 also needs to carry out a series of important actions such as a mid-course trajectory correction and a braking operation. After it enters an elliptical frozen orbit around the moon, it also needs to conduct communication tests ...

Queqiao relay communications satellite was developed to provide relay communications services for the Iander and the rover on the far side of the moon.From entering into its halo mission orbit around the Earth-moon libration point 2 on June I4,2018,it has operated on orbit more than fifteen ...
Also riding on Queqiao is a pair of microsatellites that will be released into an elliptical lunar orbit for similar radio astronomy experiments as the Dutch antenna. The twin microsatellites, developed by Chinese scientists, will carry out interferometry tests to demonstrate the feasibility of a futu...
China launched a relay satellite on Wednesday morning to lunar orbit to pave the way for the space power's prospective trailblazing expeditions to the moon. The Queqiao 2, or Magpie Bridge 2, satellite was lifted atop a Long March 8 carrier rocket that blasted off at 8:31 am from a coast...
While in orbit, it can "see" both the earth and the far side of the moon. From earth, the orbit looks like a halo on the moon, said Zhang. The concept of deploying a relay satellite in the halo orbit was first put forward by U.S. space experts in the 1960s, but was realized ...
