Space Shuttle Solid Rocket Booster

The Space Shuttle Solid Rocket Booster is the rocket that provides 83% of liftoff thrust for the Space Shuttle. It is the largest and most powerful solid rocket ever flown, and the most powerful rocket motor of any type ever flown. Each SRB produces 1.8 times the liftoff thrust of the F-1 engine used in the Saturn V moon rocket.

The two reusable SRBs provide the main thrust to lift the Space Shuttle off the pad and up to an altitude of about 150,000 feet . In addition, the two SRBs carry the entire weight of the external tank and orbiter and transmit the weight load through their structure to the mobile launcher platform. Each booster has a liftoff thrust of approximately 2,800,000 lbf at launch. They are ignited after the three space shuttle main engines' thrust level is verified. The two SRBs provide 83 % of the thrust at lift-off. Seventy five seconds after SRB separation, SRB apogee occurs at an altitude of approximately 220,000 feet , after which they land on parachutes; impact occurs in the ocean approximately 122 nautical miles downrange, after which the two are recovered.

The aspiration for interpersonal combination is the most powerful motivated in man.

All forms of orgiastic unions are controlling and even violent; they are temporary and periodical. It is a union in which the individual self disappears to a large amount and where the aim is to belong to the group. There is orgiastic condition, which may have the form of sexual orgasm, alcohol, drugs and etc. Regrettably, equality today means similarity, rather that oneness. Orgiastic unions result in a rising sense of separateness. People try to be equal by performing tasks and feelings agreed by the system and trying to follow the similar rules, the same model of life from the age three or four. Union by consistency is calm and it is permanent.
