(1) We should learn from their spirit of dedication and courage to climb the peak of science and technology. In scientific exploration, success and risk often exist. Spacewalk is the first attempt in China's space science and technology field. At the moment when they stepped into Shenzhou VII, the three space heroes also understood what it meant. However, they practiced the famous saying of Armstrong, the first astronaut who landed on the moon, with practical actions. Isn't this a selfless dedication? In our life and work, we should follow their example, give more and care less, and be a happy "true" messenger.

(2) We should learn from their rigorous scientific spirit. From Shenzhou-1 to Shenzhou-7, from manned spaceflight to spacewalking, all the complicated procedures reflect the word "rigor". It is precisely the rigorous working attitude of space science and technology workers that has led to one new breakthrough after another in China's manned spaceflight. Rigidity is not only a scientific attitude, but also an attitude towards life, which we should vigorously carry forward and inherit in our future work and life!

(3) Learn their spirit of unity and cooperation. For the successful launch of Shenzhou VII, many scientific and technological workers in front of the stage and behind the scenes have integrated the spirit of unity and cooperation into the whole team, into the hearts of every aerospace scientific and technological worker, and wrote a magnificent hymn: Unity is strength! It is with the concerted efforts of all astronauts that this spacewalk mission can be successfully completed.
