It is not a difficult thing to launch rockets nowadays. The US, Europe, Japan, Russia, China, Canada, India, Brazil, Korea, etc. have all been conducting their own space projects as well as exploration rocket projects. Until now, there have been more than ten thousand rocket launches around the world. In addition to national space exploration rocket projects, some universities even have their own rocket launch sites. Taiwan’s research and development projects of space exploration rockets started in 1997, and the National Space Organization is in charge of developing rocket technologies.
