【目标:日地拉格朗日L1点!#嫦娥五号#轨道器开展拓展试验】12月17日,嫦娥五号任务轨道器与返回器实施分离,并顺利执行规避机动。在完成既定主任务后,轨道器启程飞往距离地球约150万公里的日地拉格朗日L1点,进行环绕飞行并开展探测试验。日地L1点探测试验后,将根据轨道器状态和约束条件等情况,视情开展其他拓展任务。(来源:中国探月工程)

[Target: Sun and Earth Lagrange L1 point! Chang'e-5 orbiter launches extended test]
On December 17, the Chang'e-5 mission orbiter and the returner were separated and the evasion maneuver was successfully executed. After completing the established main mission, the orbiter set off for the Sun Earth Lagrange L1 point, about 1.5 million kilometers away from the earth, to carry out a circumnavigation flight and conduct exploration tests. After the sun-earth L1 exploration test, other extended tasks will be carried out according to the status of the orbiter and the constraints. (Source: China Lunar Exploration Project)
Unofficial report that Chang'e-5 orbiter has arrived at L1 Sun-Earth Lagrange point.An update from the China Lunar Exploration Program (CLEP) on January 19th states that the spacecraft is now 1.43 million kilometers (889,000 miles) from Earth and will arrive at the L1 Sun-Earth Lagrange point in mid-March. Once at L1 between Earth and the Sun, the probe will test the design and control of the orbit, take readings of the radiation environment, and make observations of the Sun.
This gravitationally stable orbit offers a prime vantage point for solar observations. The 25-year-old Solar and Heliospheric Observatory (SOHO) still operates there, as does NASA’s Deep Space Climate Observatory (DSCOVR).
