Why can a rocket launch multiple satellites?

The traditional method of launching satellites is to use a rocket to launch a satellite. Using a rocket and launching multiple satellites into orbit is an advanced aerospace rocket launch technique. Because a rocket launch costs millions of dollars and takes many years, the amount of work is relatively large, the scope of coverage is also very wide. Moreover, each rocket launch has to endure certain risks.

Launching a rocket with many satellites is relatively low cost, relatively high efficiency, so in some ways it shows a country's aerospace technical level.

Launching a rocket with multiple satellites is relatively low cost, relatively high efficiency.

The technique of a rocket with many satellites generally uses two launching methods: one is to launch many satellites at the same time , put into similar orbits, the distance between satellites at a certain distance. ; The other is to use the rocket's bottom-floor engine to launch several times, launching each satellite one after another, causing them to enter separate orbits. Apparently the second technique is much superior.

To make a rocket launch many satellites need to solve many key techniques.

1. First of all, it is necessary to improve the transport capacity of the rocket to bring some large satellites into orbit.
2. The second is to have a firm grasp of the stable and reliable "satellite-rocket" technique , ensuring no errors.
3. The rocket during the final flight, the satellite separated in order from the satellite compartment as designed before both collision with each other and not pollution each other.

It is also necessary to choose the best flight path and determine the best separation time to get more satellites into their correct orbits. In addition, it must be considered: if a rocket carries many satellites, the hardness and focus of the missile structure will not be changed to keep the rocket stable. Missiles and many satellites during flight, electronic devices may bring radio interference.

The earliest country to carry out the engineering of a rocket carrying many satellites was the United States. In 1960, the United States led the successful launch of a rocket carrying two satellites.

The Soviet Union has also previously launched a rocket carrying eight satellites.

China began on September 20, 1981 using the "Storm No. 1" rocket carrying three scientific experimental satellites, becoming the fourth country in the world to master the technique of launching a rocket carrying multiple satellites. From 1981 to present, China has conducted 12 launches with multiple satellites, bringing three satellites, or two satellites into orbit, including many foreign satellites. This proves that the technique of a rocket carrying many satellites of China has reached a relatively high level.

1. NASA launched into orbit of 8 micro satellites that could forecast storms
2. SpaceX will launch more rockets than any other country this year
