Like everything in life:
There is a benefit and a cost to everything.
Solid Motor Rockets (SMRs)have these advantages:
1- very simply to build, not complicated, less can go wrong
2- can be tailored to provide differing thrust at different stages of its burn
3- provides extra "oomph" (delta-V) to help rocket go higher/faster
4- can be jettisoned after use to save weight
Disadvantages:
1- once they are ignited, they cannot be "turned-off"
2- if they malfunction, usually an explosion results.
SMRs can help a spacecraft achieve orbit in a fairly safe, fairly inexpensive manner.
The most costly part of any rocket launch, with respect to fuel consumption, is the very begining of its journey, at lift off. The amount of fuel needed to get the entire rocket moving and through the thickest part of the atmosphere.
The SRMs are best use at the very beginning of a launch for this reason.

What is burn time in solid rocket motor?
It depends on the motor. The Space Shuttle's 4-segment motor burns for 124 seconds, for instance. The Atlas V's solid rocket motors burn for 90 seconds. A common size B4 model rocket motor burns for 1 second. it depends on the size of the rocket, the grain material, and the oxidizer to tell you how long one will burn.
How many solid rocket boosters does the space shuttle use?
Each shuttle used 2 solid-fuel rocket boosters, which were designed to be recovered and re-used.
What part of the space shuttle is reused?
The orbiter, the airplane looking part, and the solid rocket boosters are reused. However, the SRBs (solid rocket boosters) have to be completely dismantled and almost totally rebuilt.
Why do space shuttles have solid rocket boosters?
to beat gravity of the earth
Which rocket on the space shuttle are most powerful?
The solid rocket booster or SRB's as they are known. They pack a right punch I can tell thee!

What is a hybrid Rocket propellant?
A hybrid rocket is the rocket with a rocket motor that uses propellants in two different states of matter; one liquid or gas and one solid.
Is rocket fuel solid or liquid?
There are solid rocket fuels, and there are liquid rocket fuels.
What are solid rockets?
The correct term is "solid propellant rocket". These are rockets that burn fuel that is not a liquid(or they are NOT liquid fuel rockets). These rockets have a fuel that is poured into the rocket case and turns to a solid. Once ignited, there is no stopping the burn or controlling it.A simple example of this is rocket you shoot on the 4th of July. It burns black powder that has been formed into a cardboard case.Whereas, a liquid fuel rocket can be controlled by varying the amount of fuel that is injected into the rocket motor.
Can a solid fuel rocket work without oxygen?
Yes. Solid rocket fuel contains its own oxidizer.
What has the author Robert L Porter written?
Robert L Porter has written: 'Star 48 solid rocket motor nozzle analyses and instrumented firings'
What is the purpose of the nozzle in a rocket?
To shoot the rocket up into the sky.
Are the solid fuel rocket or the liquid fuel rocket faster?
liquid fuel
How do they put a rocket motor into a rocket?
If you have a standard kit, the motor goes in the tube at the bottom so that the end of the motor with a clay nozzle sticks out. Place an igniter in the motor and (if you are using Estes or Quest motors) put the plug ontop of the igniter and push it in. Turn the rocket upright and put it on the pad. If you don't have a rocket with a motor mount meant for this than don't try it.
Which engine does a real spaceship have?
Hydrogen/Oxygen rocket motor and chemical rocket motors.
What is the purpose of a launch rail?
The purpose of a launch rail is to hold the rocket steady during takeoff so that the rocket isn't tipped
