The making of heroes - the women and men of China's space program

Since Yang Liwei first flew into the great beyond, Chinese taikonauts have completed six manned spaceflights, conducted over 100 experiments and orbited the earth for a total of 68 days and nights.

In early January, to commemorate the 20th anniversary of the taikonaut corps, all 11 taikonauts who have been to space gathered in one of the training centers, raised their clenched fists, and revisited the oath of bravery and commitment they took years before.

In the most recent Shenzhou-11 mission in 2016, Jing Haipeng and Chen Dong stayed in the space lab Tiangong-2 for 30 days.

In the near future, when China's space station is finally in orbit, manned space missions will be a regular occurrence. Engineers and even tourists will go to space.

Zhang Xiaoguang and his colleagues have already thrown themselves into preparations for work on the space station, and his words on completing the Shenzhou-10 mission ring more true than ever.

"Our space dream knows no boundary, and our toil will never cease."
