China has unveiled its design for the external appearance of its Mars voyager, which is expected to be launched around 2020.

A campaign has been launched to find a name and a logo for the voyager. Chief designer, Zhang Rongqiao, told us more about the project.

"Through years of analysis of Mars exploration, and taking into consideration our current technology and the international trend, we've decided to divide our mission into two steps. Step one is to orbit Mars. Step two is to bring back samples. That will be accomplished in 2030," said Zhang Rongqiao, chief designer of China's 1st Mars exploration mission.
