Replacing the Mercury Planetary Orbiter in its trolley
The Mercury Planetary Orbiter (MPO) Structural and Thermal Model (STM) being lowered back to rest on its ground handling trolley. The Inter-Module Hardware (IMH) cup interfaces have now been removed from the trolley and replaced with their Mechanical Ground Support Equipment (MGSE) equivalents. The thin, red spacers employed to prevent the IMH cones from making contact with the MGSE can be seen on top of the trolley interface pillars.
