China successfully launched the Chang’e-4 relay satellite to the Earth-moon L2 Lagrange point on Sunday. The spacecraft, which is named Queqiao, was lofted into space aboard a Long March 4C booster from the Xichang Satellite Launch Center.

The satellite will relay data for the Chang’e-4 lunar rover and lander, which is set for launch late this year from Xichang. The rover will explore the South Pole-Aitken Basin as part of the first mission to explore the far side of the moon. The flight will also feature a lunar orbiter.

Sunday’s launch included two microsats that will conduct astronomical observations from deep space.

In recent weeks, Chinese officials have revealed more details about the investigation into the Long March 5 launch failure last year as well as their ambitious launch plans for this year, which include a landing on the far side of the moon.

Long March 5 will be returned to flight in the second half of 2018, according to Bao Weimin, head of the Science and Technology Committee of the China Aerospace Science and Technology Corporation (CASC). Engineers have identified the cause of a launch failure that occurred last July and are working to verify it, he said.
