Rockets are the most important way for humans to enter space. In order to explore and use the deeper universe, the world s space powers have launched heavy-duty launch vehicle development programs, and Chinese astronauts have also stepped up their own heavy-duty launch vehicles. The carrying capacity of heavy-duty rockets will now be On the basis of the Long March V large carrier rocket, it has been greatly improved, mainly aimed at deep space exploration, and its lunar transfer orbit carrying capacity can reach 50 tons. In this way, it can meet the needs of establishing a lunar base in the future and manned landing on the moon. China's Mars exploration and other deep space exploration provides a powerful launch platform. This text mainly introduces:. ['The rocket transport system will usher in technological innovation.', 'International space technology research enters a new stage.', "The development of China's heavy launch vehicle will provide support for deep space exploration.", 'Countries vigorously develop heavy launch vehicles to build deep space exploration platforms.']
