How Do Rockets Carry The Satellites?
The science behind the launching of rockets into space orbits has not changed ever since the 19th century. After the invention of “gun powder” in China, humans have been using explosives to attain controlled explosions. These explosives are fired up to acquire maximum pressure for the rockets to be able to break through the layers of the atmosphere. Since the late 1950s, countries have been launching satellites with the help of rockets to explore space and find answers for some of the mysteries.
The working behind rockets
The fact that rockets work by a mechanism of pushing themselves against the air is the same old story. But did you know that they are also designed to acquire momentum and work in a vacuum once they leave the earth’s troposphere? Yes, rockets take advantage of the power of a moving object and gain energy.
For example, consider yourself on a skateboard who’s trying to throw a basketball. What happens when you release the ball from your hands? Your skateboard will start moving in the opposite direction conserving a level of momentum. In the same way, rockets also use the same system to achieve strong propulsion.
Stages of a rocket launch
There are two stages of a rocket launch. The first stage is to cross the dense layers of the atmosphere that requires several engines and enormous fuel supply. As the rocket moves higher it encounters more air resistance and experiences a thinner atmosphere.
The first stage is just the dispatching of a portion whereas the second stage has a huge role to play. Once the rocket enters a specific region, it releases the satellite into the orbit. Rockets like Blue origin new Shepard are a powerful class of rockets that can launch several satellites into the orbit.
Class of rockets – satellite launching
Orbital class of rockets is powerful to launch objects in the orbit that are made to revolve around the earth. A satellite must be accelerated at a speed of approximately 17,000 miles an hour to remain in the circular orbit of 500 miles, just about the earth’s surface.
During the Apollo missions of launching a satellite into the orbit, rockets like Saturn V, Delta IV heavy spaceships, Falcon rockets can lift to 20,000 to 30,000 pounds of massive satellites into the earth’s orbit. Satellites are usually launched near the equator because it’s more efficient and rotates faster than the poles. But we can expect reusable rocket parts that can reduce the cost of launching satellites very soon.
