1-Intro

In todays world the majority of the space launch cost comes from building the rocket which takes the satellite or payload to its orbit. Once it leaves to its orbit the rocket or the launch vehicle is destroyed or left behind as the 40 percent of the whole cost of the launch is in launch vehicle . If one can find how to effectively reuse rockets just like airplanes, the cost of access to space will be reduced by as much as a factor of a hundred.

3-falcon 9 Re-Usable vehicules overview

SpaceX privately developed the Falcon family of launch vehicles :The Falcon 9 and the Falcon heavy

-We will talk about Falcon 9 re-usable the vehicule is powered by liquid oxygen and kerosen and can be equipped with a SpaceX Dragon spacecraft which is a spaceship

Falcon 9 re-usable first launch was on december 21th 2015

The overall goal of F9R is to make Falcon 9 fully re-usable by returning them to a landing site vertically Falcon 9 is planned to return to the launch site after separation and land it vertically on deployable landing legs.

4-Conclusion

Compared to other launch vehicles the F9R is a reusable launch vehicle.

By using F9R the cost is being reduced by 40 percent ; But The Falcon 9 experiences major temperature changes during its flights, as well as intense pressures and vibrations from the winds in the atmosphere. furthermore restore a rocket engine is often expensive. And if those repairs take too long, SpaceX cant launch its vehicles as frequently. finaly To launch F9R the climate condition should be absolute normal, the vertical landing is very complicated , if any thing goes wrong whole vehicule would be destroy.

F9R = Falcon 9 Re-usable
