The Shenzhou-21 crew aboard China's orbiting space station released a music video tracing the country's space endeavors, blending their scientific mission with a musical tribute to celebrate the Spring Festival, which falls on Feb. 17 this year.

Taking a break from their busy schedule in orbit, the trio -- Zhang Lu, Wu Fei and Zhang Hongzhang -- recorded the song "The Five-Starred Red Flag Flutters in Space", specifically composed for Chinese space professionals.

Ahead of the music video, the crew shared their personal reflections on the national flag.

"The first time I performed a spacewalk, the five-star red flag of China outside the cabin was shining with dazzling brilliance," recalled Wu Fei.

"That five-star red flag is the most beautiful scenery in my heart," said Zhang Hongzhang.

"Let the five-star red flag fly high in space," the trio said together, setting the stage for their musical tribute recorded 400 kilometers above the Earth.

The video pays tribute to the pioneers of the space program, featuring footage of China's first astronaut in space, Yang Liwei, alongside subsequent generations of astronauts who have followed in his path.
