The plan was released to coincide with China's first "Space Day" which was celebrated1 on Sunday.
According to the ambitious plan, the Mars mission probe is expected to orbit the red planet, land and deploy2 a rover all in one mission, round about the year 2021.
The spacecraft for the mission will be put into space by the new-generation Long March-5 heavy-lift rocket, and is being developed by the China Academy of Space Technology.
Zhang Rongqiao, chief designer of the first Mars exploration, explained its significance for understanding the universe's evolution, as well as structure of matter and the origin of life.
"Such a big plan to achieve orbiting, landing and the deployment3 of a rover in one mission will make history. Only by completing this Mars probe mission can China say it has embarked4 on the exploration of deep space in the true sense."
However, Zhang also stressed the difficulties that would be faced in achieving this goal.
"A total of 43 Mars missions have been launched throughout the world so far. The most recent took place on March 14. It is a joint5 collaboration6 between the European Space Agency and the Russian Federal Space Agency. It's just been launched and it is still on its way to Mars. There have only been 22 successful launches. So the rate of success to failure is about 50-50."
The greatest challenge lies in the landing process, since the weather on the red planet is hard to predict, and its environment is hard for researchers to imitate on Earth.
Experts also explained that since the favorable alignment7 of Earth and Mars occurs for only few weeks every 26 months, 2020 is a crucial launch window for the probe.
Meanwhile, China is also planning to finish building its space station by 2022.
The country will launch its second orbiting space lab Tiangong-2 as well as the Shenzhou-11 spacecraft to rendezvous8 and dock with it later this year.
Xu Dazhe, director of Chinese National Space Administration, explained some of the goals they want to achieve.
"China will complete its civil space infrastructure9 -- navigation, telecommunication10 and remote sensing systems -- to serve different sectors11, benefit the mankind and contribute to the improvement of people's livelihoods12."
The space station will also cater13 for international projects and foreign astronauts in a bid to develop further space cooperation with the rest of the world.
The first space lab Tiangong-1 was launched in 2011 and three dockings with the module14 were conducted in the following years.
The lab, which orbited for 4 and half years, has fulfilled its mission and was retired15 in March.
It will descend16 gradually in the coming months until it burns up in the atmosphere.
The U.S.-dominated International Space Station is scheduled to end its life in 2024, when China's space station may for a time become the only operational facility in space.
