Rockets+3B

rocket engines are3,000 times more powerful than a car engine. most rocket engines operate by burning fuel. Solid-fuel boosters rochets burn out and are discarded at 32 miles above the ground witch takes about two minutes. Two pressurized tanks that contain liquid hydrogen and oxygen. During launch,the fuel is fed to the rockets three main engines. Most rocket boosters are around 360 feet tall. Nasa's space shuttles are the most complex flying machines. the v-2 rocket was a single stage rocket fueled by alcohol and liquid oxygen.

the austranots started to lift of the ground with there three main thrusters powering them of the ground and then they cut off and the two other thrusters (as powerful as 3,000 cars enginse) start two power them through the lawers of the atmispher and the gravity of the earth when they got into space they began to be attacked by a gaint space crab that was walking on the earths autmisphere and it was angry becuase it had not yet ben fed witch also made it hungery. But acting kwick the space ships leader john fired the big lazer at the crab. The crab never being by the lazer was confused and the space men got away. Hi I'm Jeff and I am going to tell you all about rocket engines becuase that is what my job is based on the engines of the rockets nasa builds. Rocket engines compared to car enginse are 3,000 times more powerful, so imagine your mom taking you to school in a rocket.Also like cars most rockets work by burning fuel, but unlike cars rockets lose some of there engines becuase when thier empty they weigh down the rocket and have no more use. So the solid-fuel boosters are discarded 32 miles above the ground and most boosters are around 360 feet tall. Today Nasa's space shuttles are the most complex flying machines. One of the old modles was called a v-2 rocket and it was fueled by alcohol and liquid oxygen.Did you know? That the first rockets were invented by the Chinese a spinoff from thier invention of gunpowder.
