  Galaxy is full of eyes, youth without regrets.

  [Explanation] On the eve of the launch of China's first Mars probe, Qi Tielei, director of the Comprehensive Department of the National Space Administration's Lunar Exploration and Space Engineering Center, used these eight words to express his feelings at this time.

  Like him, many young people have contributed their strengths in their respective positions during the Mars exploration mission. Gao Fenghe from the General Department of the Fifth Academy of Aerospace Science and Technology Group is the test commander of the Mars exploration mission. He said he is a Martian "post-90s" and has an unusual relationship with Mars.

  When I first took over as the commander, I was living a lot every day, not only had to complete the satellite test work, but also arranged the daily test process tasks and coordinated with various interfaces. It would be awake day by day. No matter what time I get off work every day, I basically wake up at about 5:30. After waking up, it's all about my head. Then my colleague said to me, "Gao Yu-hyuk, you are especially suitable for going out on blind dates in the future. Telling people that sleep is suitable for bringing children, and wake up at 5:30 every day, girls don't need to wake up at all." Of course, I didn't dare to say this later. When I came up with a blind date with a girl, I said that the child was awake. It was too rude to say.

  [Explanation] Talking about his high-intensity history of overtime, Gao Fenghe has a sense of humor in his words. But when he talked about the dedication stories of his colleagues around him, the expression on his face became much more serious.

  Like the people who came to our testing team at the launch site of the probe, some had their daughters who were just born. They came to the launch site in less than a month and worked for 120 days. Some people just got married, that is, married for three or four months, and then they came to the launch site. Before leaving, I must have been very reluctant to say "disagree", but in terms of actions, I was very supportive of our work.

  [Explanation] Zhang Zemei, chief engineer of the Mars exploration mission orbiter of the Eighth Academy of Aerospace Science and Technology Group, has worked this year for ten years. Born in 1985, she said that she was the "age responsible" in the team and was called the "sister" for many years. The experience of struggle with the post-90s and post-95 colleagues in the team has become Zhang Zemei's most proud of.

  We may have some youthfulness, some rebelliousness, and some dislikes. But I want to say that after several years of personal experience, I also found that the young people around me really don't like to talk about it, but it doesn't mean we can't carry this career. Our group of people have gone through such a long period of struggle. After four or five years, sometimes ten years, this may be a course of our life, but no matter what else we can experience later, I think this should be very precious to us. A journey in the past is also a journey that can be bragged with for a while with the child.

  [Explanation] Gao Xianhe's department is the place to complete the whole star test mission. Their team is also the closest person to the satellite. Therefore, after coming to China's Wenchang Space Launch Site, Gao Xianhe also received a special mission.

  One day our chief designer said to me, "Gao Yuhe, we have to say four words to the base commander at last, called'detector is good'". These four words are very important, because they are telling the whole base, telling us the whole launch site, telling us the whole country that our satellite is ready, and these four words must be spoken well and spoken. The momentum speaks of the confidence of our detector, but also the confidence that we will win.

  [Explanation] Within a few days of receiving the task, Gao Yu-hyuk began the process of practicing his password against the sea. After repeated practice, he now has the confidence to say this password clearly and accurately. Gao Fenghe also hopes that on the launch day, his password can send blessings to the Mars exploration and launch mission.
