Hydrazine• Oxidzer: Nitrogen
Tetroxide
R.C.S.– 44 thrusters on the
nose and tail of the Orbiter
– Same propellants as OMS
Demo
Time
Three Fuel Cells provide electricity for the orbiter– Oxygen + Hydrogen =
• Electricity • Water
Length: – 60 feet– 18.3
meters
Width: – 17 feet– 5.2
meters
Depth: – 13 feet– 4 meters
Hitch a ride?– Not pressurized
or temperature controlled
Uses:– EVA and Cargo
Remote Manipulator System– RMS or “Canadarm”
moves payloads and assists with EVA
Orbital Inspection Boom– OIB is used with RMS to
inspect heat-tiles for damage
The only pressurized and temperature controlled part
of the Orbiter
E.C.L.S.S. (ee-kliss)– Removes CO2– Cools avionics and equipment
