Treadmill with Vibration Isolation Stabilization

The Treadmill with Vibration Isolation Stabilization System, commonly abbreviated as TVIS, is a treadmill for use on board the International Space Station and is designed to allow astronauts to run without vibrating delicate microgravity science experiments in adjacent labs. International Space Station treadmills, not necessarily described here, have included the original treadmill, the original TVIS, the БД-2, the Combined Operational Load-Bearing External Resistance Treadmill (COLBERT), and the Treadmill 2 (abbreviated as T2). Some share a name, some a design, some a function, some use different (passive) vibration-suppression systems, some it is unclear how they differ.

The name for the treadmill (COLBERT) came about due to a naming contest that NASA held for what became the Tranquility module. Comedian and TV personality Stephen Colbert used his show The Colbert Report to encourage his viewers to write in votes to use "Colbert" during the contest. After the results of the contest were announced, NASA decided to use Colbert's name for the new treadmill in place of naming the Tranquility module after him.^[1]
