Quasi-steady accelerations in spacecraft are related to the position
in the spacecraft, aerodynamic drag, and vehicle rotation. For the Space
Shuttle Orbiters, these accelerations are on the order of lx10 -6
g and vary with the orbital frequency.
 |
The quasi-steady microgravity environment on the Orbiter
Columbia shows the effects of variations in Earth's atmospheric density.
The primary contribution to the variation is the day/night difference
in atmospheric density. The plot shows that the drag on the Orbiter
varies over a ninety minute orbit. |

g-jitter indicates the vibrations experienced by microgravity
experiments (for example on parabolic aircraft and the Space Shuttle)
that cause effects similar to those that would be caused by a time-varying
gravitational field.
