The Shenzhou-20 crew on board China's orbiting space station on Wednesday extended greetings to children in celebration of the upcoming International Children's Day on June 1.

The crew, made up of astronauts Chen Dong, Chen Zhongrui and Wang Jie, reflected on their childhood aspirations as young pioneers to contribute to China’s space exploration.

They expressed hope that today’s youth would actively play a role in the nation's progress.

The Chinese Young Pioneers (CYP) is a national organisation for Chinese children.

"I still remember the first time I put on the [young pioneer's] red scarf. It was then that I made a silent vow to become someone who could contribute to society. That childhood dream has guided me through my journey in the aerospace field, and it's what has brought me to space today," said Chen Dong.

"Back when I was a young pioneer, I was fascinated by the blue sky and curious about what was beyond Earth. When China's first manned spacecraft, Shenzhou-5, was launched, I was thrilled, and it strengthened my determination. Today, I've finally realised my dream and am able to work aboard China's space station," said Chen Zhongrui.

"I have been remembering clearly the first line of the CYP anthem: 'We are the successors of communism.' This song has inspired generations of young pioneers to honour the legacy of our revolutionary predecessors, following in their footsteps with courage and striving toward our ideals," Wang said.

"When I sang this as a child, it always filled me with a sense of strength. Today, I'm proud to be an astronaut, contributing to our country's space endeavours. In the future, I hope you, the younger generation, will carry the baton and help China's space exploration to take steadier and farther steps."

Chen Dong added: "This time, we brought the CYP flag to China's space station.... We believe you will take up the baton of history, starting by learning from the pioneers and growing into true pioneers, with the ambition to serve and strengthen our nation, and to be resolute and responsible strivers."

The crew declared a "happy Children's Day to all the children" as they waved a Chinese Young Pioneers flag.
