What Is the Relationship Between Space and Earth Science?

Space science, or space science, is a science that mainly uses space vehicles or remote sensing devices to study natural phenomena such as physics, astronomy, chemistry, and life activities that occur in space and their laws. ^[1]

Space Science is also called space science. There are broad and narrow senses. Broad space science refers to all sciences involving space, including space technology science, space applied science and basic space science; narrow space science refers to the use of space vehicles to study the physics, astronomy, and chemistry of space And the science of natural phenomena such as life. Its main contents include: space physics, space astronomy, space chemistry, space geology and space life science. The development of space science has enabled humans to have a deeper and comprehensive understanding of the environment around the earth and the laws and mechanisms of change, and has helped to explore some basic scientific issues such as the universe, the origin and evolution of life. At the same time, it will also continue to promote the faster development of space application technology and open up new application areas. ^[2]

Space science rocket

The rocket, or injector, is a vehicle that uses the ejected material to create a reaction force. The rocket mechanism was first used to launch arrows, so it is called a rocket in Chinese. Rocket propulsion is a precise structure. Its principles are mainly mechanics, thermodynamics, and other related scientific applications, such as electricity. The main difference between a rocket and an ordinary aircraft is that the aircraft can only fly in the atmosphere, but the rocket can work in outer space because it can burn and propel without using outside air. Rocket thrust is generated by the reaction of high-speed ejections. The principle is the same as when the water pipe sprays water, and the gun goes back. After the rocket fuel is burned through the combustion chamber, high-temperature and high-pressure gas is generated, and then it is accelerated through a nozzle and exhausted to the outside. These gases are the driving force behind the rocket.

Space science spacecraft advance

Space vehicle propulsion is any method of accelerating space vehicles and artificial satellites. There are currently many known ways, each of which has weaknesses and advantages. Many of the current propulsion methods are rockets.

Space science interstellar

Interstellar navigation is a collective term for interplanetary and interstellar navigation. Interplanetary navigation refers to navigation in the solar system, and interstellar navigation refers to the flight of interstellar space outside the solar system. Unmanned interplanetary voyages have been achieved, while interstellar voyages are still in the exploration stage.
