Walz, both mission specialists, tilt the Active Rack Isolation System (ARIS) hardware which was included on this flight to evaluate conditions and hardware requirements for the International Space Station (ISS). The ARIS is designed to isolate certain experiments from major disturbances that are expected to be found on the ISS, such as vibrations caused by the movement of mechanisms and crew members and the operation of equipment. STS-79 was chosen for the inclusion of the experiment because the Shuttle-Mir complex more closely approximates the acceleration environment of the ISS.
