Overview

A team led by Christopher Carr (full citation below) performed some testing with a Slam Stick to quantify the "weightless" or reduced gravity conditions experienced in space or on planetary surfaces, e.g. the Moon or Mars. In their paper, they present a method for collecting, analyzing, and classifying the altered gravity environments experienced during a parabolic flight. Specifically, they used Slam Stick during a Boeing 727-200F flight with 20 parabolas.

Their data and analysis code are freely available:

Results

The following figure shoes the section of the aircraft the Slam Stick was located in, the orientation, the raw DC data, and then the filtered data.

The following is a power spectral density of g level that was used to help identify the filter frequency cutoff to use.
