High above the Earth in the orbiting International Space Station, Expedition 31 Flight Engineer Don Pettit modified an Ethernet cable for the Muscle Atrophy Research and Exercise System (MARES) experiment Monday. MARES aims to further understanding of the effects of microgravity on the muscular system.

Flight Engineer Joe Acaba participated in an ambulatory monitoring session with the Integrated Cardiovascular (ICV) experiment. ICV researches the extent of cardiac atrophy – the weakening of the heart muscle – on long-duration spaceflights and seeks to identify its mechanisms.

Sergei Revin, also a flight engineer, joined Commander Oleg Kononenko in working with the radiation payload suite Matryoshka-R, which is designed for sophisticated radiation studies and is named after the traditional Russian set of nested dolls.

Flight Engineer Andre Kuipers installed hardware for the Dose Distribution Inside the International Space Station – 3D experiment, or DOSIS-3D, which will help determine the radiation environment throughout the station.

Kuipers also exchanged some lamps in the Fluid Physics Experiment Facility and checked the upstream resistance of the power connector of the Image Processing Unit to determine the upstream status of the connector.

Later in the day, Pettit performed maintenance on the Waste Recovery System and, with Acaba’s help, unpacked and stowed items brought up on the Soyuz TMA-04M spacecraft that delivered the three newest Expedition 31 crew members – Acaba, Revin and Flight Engineer Gennady Padalka – to the orbital outpost. Padalka, Acaba and Revin continued their onboard orientation, learning the layout of the station and continuing to familiarize themselves with the orbiting laboratory’s operations.

The SpaceX Falcon 9 rocket that bears the Dragon commercial cargo vehicle sits atop the launch pad at Cape Canaveral Air Force Station in Florida following inspections on an engine that shut down during Saturday’s launch attempt. SpaceX has confirmed the rocket is on track to launch Tuesday, May 22 at 3:44 a.m. EDT. The station crew is set to grapple and berth the supply ship to the Harmony node’s Earth-facing Common Berthing Mechanism a few days later. On this demonstration flight, Dragon will be the first commercial cargo vehicle employed to deliver supplies to the complex.

The strenuous body exercise with some supplementary; Vitamin C a reducing agent will mend muscular atrophy and generate collagen fibres in muscle will be key success to healthy physic at microgravity.
