New York, Jul 29 (IANS): A Russian Soyuz MS-05 carrying the three new crew members to join the Expedition 52 docked to the International Space Station (ISS) after a six-hour spaceflight, to continue important scientific research in the orbiting laboratory, NASA said in a statement.

NASA astronaut Randy Bresnik, Sergey Ryazanskiy of the Russian space agency Roscosmos, and Paolo Nespoli of European Space Agency (ESA) launched aboard the Soyuz MS-05 at 11.41 a.m. on Friday from Baikonur, Kazakhstan.

The three crewmates aboard the Soyuz MS-05 spacecraft orbited Earth four times, before docking at the space station.

Their arrival restored the station's crew to six people, which includes Expedition 52 Commander Fyodor Yurchikhin of Roscosmos and Flight Engineers Peggy Whitson and Jack Fischer of NASA.

The new Expedition 52 crew members will spend more than four months conducting approximately 250 science investigations in fields such as biology, Earth science, human research, physical sciences and technology development.

The expedition team is expected to soon conduct new science investigations arriving on SpaceX's 12th NASA-contracted commercial resupply mission targetted to launch in August.

The astronauts will assemble and deploy a microsatellite investigation seeking to validate the concept of using microsatellites in low-Earth orbit to support critical operations, such as providing lower-cost Earth imagery in time-sensitive situations such as tracking severe weather and detecting natural disasters.

In addition, their work will also include an invesitgation into the study developed by the Michael J. Fox Foundation of the pathology of Parkinson's disease to aid in the development of therapies for patients on Earth as well as the use of the microgravity environment in stem cell research

Whitson, Fischer and Yurchikhin are scheduled to remain aboard the station until September, while Bresnik, Ryazanskiy and Nespoli are scheduled to return in December.
