        Earlier this year, China achieved a new milestone(里程碑) in space exploration(探索). On Jan 3, Chang'e 4 became the first space probe(探测器) in history to land on the far side of the moon, People's Daily reported.
        From Earth, we can only see one side of the moon. The other side has been a mystery. Scientists have long wondered what lies on this side of the moon.

        Chang'e 4 has sent back photos of the far side of the moon. It is also used to carry out experiments, such as growing seeds in a low-gravity(低重力) environment. The data(数据) collected from these experiments could be used to help us build a base on the moon in the future.

        The success of the Chang'e 4 mission(任务) is a main achievement for China's space program. It marks a new stage in China's deep space exploration, said Wu Yanhua, head of China National Space Administration.

        China launched(启动) its lunar(月球的) exploration program in 2004, naming it Chang'e. Chinese scientists set three goals —“orbiting(环绕运行), landing and sample(样本) returning”— referring to launching probes that could circle around the moon, touch down on its surface and bring lunar materials back to Earth.

        Chang'e 4 has realized the goal of landing. The third will be achieved during the Chang'e 5 mission, which is set to take place before the end of this year, China Daily reported.

        Following the success of the Chang'e missions, Chinese scientists are looking even farther into our solar system (太阳系). China's first Mars(火星) mission is expected to be carried out by 2020, Wu said.
