PHYSICAL SCIENCES
Much of our understanding of physics is based on the inclusion of gravity in
fundamental equations. Using a laboratory environment found nowhere else, the
U.S. Destiny laboratory on space station provides the only place to study long-
term physical effects in the absence of gravity, without the complications of
gravity-related processes such as convection and sedimentation. This unique
microgravity environment allows different physical properties to dominate
systems, and these have been harnessed for a wide variety of investigations in the
physical sciences.
