BEIJING, April 24 (China Space News) -- China's first Mars exploration mission has been named Tianwen-1, announced the China National Space Administration (CNSA) on Friday, China's Space Day.

The name comes from the long poem "Tianwen," meaning Questions to Heaven, written by Qu Yuan (about 340-278 BC), one of the greatest poets of ancient China.

CNSA said all of China's planetary exploration missions in the future will be named the Tianwen series, signifying the Chinese nation's perseverance in pursuing truth and science and exploring nature and the universe.

CNSA also unveiled the logo of China's planetary exploration missions, featuring the letter C, signifying China, international cooperation and capacity of entering space.

Since 2016, China has set April 24 as the country's Space Day to mark the launch of its first satellite Dongfanghong-1 into space on April 24, 1970. This year is the 50th anniversary of the start of China's entry into space.
