Description: Conventional modern rocket has existed for more than a half century. However, there has been little or no significant progress in their basic data. They are very exceedingly complex and generally very expensive to build. Designers ordinarily try to improve them by simplifying in order to reduce the cost payload launches. They try to use the first stagy of rocket sometimes, because the rocket engine and body are expensive. But no significant success. The author offers a new type of rocket which does not have the usual rocket body and engine (only open solid rocket fuel). This new rocket is cheap to fabricate, may be switched on and switched off many times and has specific impulse more than conventional solid fuel engine (i.e., close to liquid fuel). One can be used for launch as well as vector correcting rocket. This method is particularly suitable for micro-spacecraft (up to 1 kg). It allows to reduce the launch weight of the rocket to 50 รท 1000 kg.
