You may remember back at the start of December,     1     China carried out their unmanned Chang’e-5 mission and the spacecraft touched down on the moon to collect samples for research. Now it     2    (success) returned to the Earth. This is the most significant event in China’s space field, and also one of the most notable space     3    (activity) globally. Chang’e-5,     4     (launch) by a Long March 5 heavy-lift carrier rocket early on Nov 24, is the nation’s     5    (large) and most complex lunar probe. It returned with 1,731 grams of lunar rock and soil to the Earth,     6    (mark) a historic accomplishment 44 years after the last lunar substances were taken back. The 23-day mission was China’s first space journey to claim extraterrestrial samples, making     7     the third country to accomplish the task, the first being the USA in the 1960’s and the second Soviet Union in the 1970’s.

The spacecraft     8    (enter) the Earth’s atmosphere at an altitude of around 120km. As soon as it was 10km above land, it released its parachute and landed smoothly in China's Inner Mongolia. Now the spacecraft has been air lifted to Beijing where the samples     9    (examine) by scientists very soon.

The mission’s results will contribute     10     mankind’s deeper understanding of the moon’s origins and the evolution of the solar system.
