ISS036-E-005384 (2 June 2013) — In the Tranquility node of the Earth-orbiting International Space Station, European Space Agency astronaut Luca Parmitano exercises on the Combined Operational Load Bearing External Resistance Treadmill (COLBERT), technically named the Treadmill 2 and abbreviated as T2. It is a treadmill for use on board the orbital outpost and is designed to allow astronauts to run without vibrating delicate microgravity science experiments in adjacent labs. It was derived from the treadmill that was originally taken to the station. COLBERT/T2 uses a different kind of vibration-suppression system than the original. Parmitano has been on board the orbital outpost for about three days and will continue his stay into November.
