Measured Success: The Microgravity Measurement and Analysis Project

Abstract

In microgravity, even minute forces can affect experiments: therefore, investigators need to know the precise strength of the gravitational levels and vibrations affecting their experiments to interpret results correctly and to develop an understanding of the effects caused by these forces. The Microgravity Measurement and Analysis Project (MMAP) at the NASA Lewis Research Center was established to provide a single source for measuring the microgravity environment on various orbiting spacecraft, providing support for scientists, and microgravity environment data. As part of this project, the Space Acceleration Measurement System (SAMS) and the Orbital Acceleration Research Experiment (OARE) have supported 15 shuttle missions. In addition, one SAMS unit has been operated on Russia's Mir Space Station since September 1994.
