A table is captioned "Table 1. Summary of Spacecraft Loads".  The table
lists several spacecraft loading events and the significance of each
loading event on design and performance of the spacecraft.  The first
loading events are inertia loads during launch and landing.  The
significance of these loads are that they drive the design of the primary
structure.  The next loading events are vibrational loads during flight
and orbit operations.  The significance of these loads are that they are
structurally transmitted, causing fatigue/fracture.  The next loading events
are vibroacoustic loads from launch.  The significance of these loads are
that they are acoustically transmitted especially for low mass/area parts.
The next loading events are thermally induced loads during flight and orbit
operations.  The significance of these loads are that they dictate allowable
temperatures and gradients and compatibility of materials.  The next loading
events are pressurization and flow induced loads from flight and orbit
operations.  The significance of these loads are that they apply to pressure
vessels, pipe lines and housings.  The next loading events are mechanical
loads from fabrication and assembly.  The significance of these loads are
that they relate to material residual stresses, fastener/seal preloads and
misalignment.  The next loading events are mechanical/thermal loads resulting
from verification testing.  The significance of these loads are that they may
limit the useful life of material.  The final loading events are mechanical/
thermal loads from ground handling and transportation.  The significance of
these loads are that they are important for the design of MGSE and spacecraft 
interface with MGSE and they may limit the useful life of material.
