From Beijing space flight control center,The chang'e-5 orbiter, under the precise control of flight control personnel on the ground, was successfully captured at 13:29 on March 15 by the sun earth Lagrange 1 point, becoming the first spacecraft in China to enter the sun earth L1 point exploration orbit.

At present,The chang'e-5 orbiter is 936700 km away from the earth, with stable attitude, energy balance and normal working conditions. It will be operated in the sun earth L1 probe orbit in the future, with a cycle of about six months.

L1 is located between the sun and the earth,

The objects in this position are subject to the same gravity from the earth and the sun. It is easier for the spacecraft to maintain a relatively stable operation state here, which can save fuel and will not be blocked by the earth or the moon. Therefore, it can observe the sun or the sun facing surface of the earth continuously for a long time, which is the best position to place the solar observation station.


The chang'e-5 orbiter will be separated from the lander on December 17, 2020, and will be under long-term management from December 21,After two orbital maneuvers and two midway corrections, it took about 88 days to arrive at L1To start a new phase of exploration mission.

Due to the high precision of the long March-5 rocket, chang'e-5 orbiter completed the process of escorting the returner,In fact, only 0.3% of the original planned fuel is consumedIn the end, more than 200 kg of propellant was left, and there was more spare force to carry out the expansion task.

In the future, Beijing space flight control center will organize and carry out routine management and expansion test of chang'e-5 orbiter according to the implementation plan of expansion test, further expand engineering and scientific exploration achievements, provide technical support for subsequent deep space exploration tasks, and explore and accumulate more experience.

It is worth mentioning that the long-term management team of Beijing space flight control center is still in chargeAt present, these spacecraft are in good condition and operate normally.
