Chang'e-5, China's lunar probe, successfully carried out its second orbital correction at 22:06 on Wednesday and continued its trip to the moon, according to the China National Space Administration (CNSA).

This follows its first trajectory correction maneuver at 22:06 on Tuesday.

The operations, according to CNSA, is designed to keep the spacecraft on the right track.

During the maneuver, the probe's two 150N engines worked for six seconds.

The Chang'e-5 probe has flown for about 41 hours and is about 270,000 kilometers away from the Earth as of the second orbit correction. All systems of the probe are in good condition.

In general, a spacecraft has to carry out several trajectory correction maneuvers before a successful landing.

Before a space flight, engineers will design a reference trajectory to describe the planned path of the spacecraft. But because of the uncertainty and disturbances in space, the spacecraft may drift away from the planned path. Sometimes even the pressure of sunlight on the spacecraft can add up over time and push the spacecraft off course.

So the control team on the ground has to closely monitor data and keep track of the spacecraft position in order to get it back on course. They need to calculate the data, create a set of commands and carry out multiple testings before uplinking these commands to the probe.

The lunar probe was carried by the Long March-5 rocket and blasted off from the Wenchang Spacecraft Launch Site in the southern province of Hainan at 04:30 on Tuesday.

The mission, named after the ancient Chinese goddess of the moon, will seek to collect lunar material to help scientists understand more about the moon's origin and formation.
