trebuchets were launched by first tying down the throwing arm. then its sling was loaded with projectiles. it was released when the sling was full. The counterweight on the other end of the throwing arm dropped, pulling the sling up and causing it to hurl the projectiles. this had to be done every time they needed to launch the trebuchet. if you don't know what "projectiles" means, then just look it up.
It prevents the spacecraft from being launched as gravity causes it to be attracted towards earth.
The launch pad (even hours after launch) is not a place you'd want to be.See the related link for more information.
İf gravity is high, satellite will be very small due to lifting forces for satellite,otherw mise satellite wll vey big.
As of today the next launch is STS-128, it's scheduled to launch August 25th, 2009.
Trebuchets were medieval siege artillery used to throw heavy stones at castle walls and open a breach through which besieging forces could enter. They could also be used to launch projectiles (or a rotting dead cow in a primitive form of germ warfare) over castle walls to weaken and lower the morale of the besieged.
