What are the semi-circle shaped components behind the wings of the space shuttle at launch?

Answer 1

I believe that they house the turbopumps for the engines.

Answer 2

Birds are incredibly secure. they'll actual delay a lauch if a great poultry or flock is nearby. poultry hits can and function brought about injury to the insulation tiles. as a methods as a results of fact the "poisonous" gases, they are greater often than not water with slightly Aluminum oxide jumbled in from the solid boosters. At lauch, a great area of the cloud you notice is water dumped onto the launch pad to hose down vibrations off the launch platform that could reason tile injury. After liftoff, the commute makes use of Hydrogen and Oxygen for the main considerable engines, springing up in basic terms water as exhaust. the solid rocket boosters derive thrust from Aluminum and emit Aluminum Oxide, that's basic interior the ambience.

Answer 3

Those "lumps" are where the engines for the Orbital Maneuvering System are mounted. Those engines are necessary to reach orbit after the big external tank drops away, to circularize the orbit, to alter the orbit, and to de-orbit to come back home.

Answer 4

The other part of the semi-circle is on the other side..........
