The development of space technology has shown that the mankind has made great achievements in its journey of the continuous research, exploration, and utilization of space. It brings about important impetus and significant changes in the economic and social developments of mankind. Especially, it can also “impact life on earth through the stimulation of technological development, and generation of scientific knowledge” said by Dr. Ernst Stuhlinger, the associate director for science of NASA Marshall Space Flight Center, in 1970. Of course, space technology is one of the most challenging missions and complex engineering in the world.
