Drop Towers

Using a drop tower, an experiment achieves microgravity via free fall.  The duration, usually a few seconds, is determined by the height of the tower.   Example drop towers are:

NASA Glenn Zero Gravity Research Facility

NASA Glenn 2.2 Second Drop Tower

NASA Marshall Drop Tube Facility

ZARM, University of Bremen, Germany

Microgravity Laboratory of Japan

GRC Drop Tower
