WASHINGTON, April 20, 2017 /PRNewswire-USNewswire/ -- After a six-hour flight, NASA astronaut Jack Fischer and cosmonaut Fyodor Yurchikhin of the Russian space agency Roscosmos arrived at the International Space Station at 9:18 a.m. EDT Thursday where they will continue important scientific research.

The two launched aboard a Soyuz MS-04 spacecraft from the Baikonur Cosmodrome in Kazakhstan at 3:13 a.m. (1:13 p.m. Baikonur time), orbited Earth four times, and docked at the space station.

The arrival of Fischer and Yurchikhin increased the station's crew complement to five. The two join Expedition 51 Commander Peggy Whitson of NASA and Flight Engineers Oleg Novitskiy of Roscosmos and Thomas Pesquet of ESA (European Space Agency). The Expedition 51 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.

Novitskiy and Pesquet will remain aboard the station until early June. Fischer and Yurchikhin are scheduled to remain aboard the station until September, along with Whitson, whose stay aboard the station was extended into Expedition 52 by an agreement recently signed between NASA and Roscosmos.

The expanded Expedition 51 crew soon will conduct new science investigations arriving on Orbital ATK's seventh NASA-contracted commercial resupply mission Saturday, April 22. Investigations arriving will include an antibody investigation that could increase the effectiveness of chemotherapy drugs for cancer treatment and an advanced plant habitat for studying plant physiology and growth of fresh food in space. Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments. Cygnus also is carrying 38 CubeSats, including many built by university students from around the world, as part of the QB50 program. The CubeSats are scheduled to deploy from either the spacecraft or space station in the coming months.

Fischer and Whitson are scheduled to take part in the fifth spacewalk of the year on May 12. The pair's main task will be to replace an avionics box on the starboard truss called an ExPRESS Logistics Carrier, a storage platform. The box houses electrical, and command and data routing equipment for science experiments and replacement hardware stored outside the station. The new avionics box is arriving aboard Orbital ATK's Cygnus cargo craft on Saturday, April 22.

The crew members also are scheduled to receive one Russian Progress resupply mission delivering several tons of food, fuel, supplies and research.

For more than 16 years, humans have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth that will enable long-duration human and robotic exploration into deep space. A global endeavor, more than 200 people from 18 countries have visited the unique microgravity laboratory that has hosted more than 1,900 research investigations from researchers in more than 95 countries.
