	September 13, 2017  RELEASE 17-077 Three New Crew Members Arrive at International Space Station The Soyuz MS-06 spacecraft carrying NASA astronauts Mark Vande Hei and Joe Acaba and cosmonaut Alexander Misurkin of Roscosmos is seen on the right approaching the International Space Station on Tuesday, Sept. 12, 2017. The spacecraft docked to the station at 10:55 p.m. EDT. Credits: NASA Television   Expedition 53 Flight Engineers Mark Vande Hei and Joe Acaba of NASA and Soyuz Commander Alexander Misurkin of Roscosmos launched from the Baikonur Cosmodrome in Kazakhstan, Tuesday, Sept. 12, 2017 (Wednesday, Sept. 13, Kazakh time) (Sept. 12, U.S. time), and arrived at the International Space Station at 10:57 p.m. to begin their 5.5-month mission aboard the station. Credits: NASA/Bill Ingalls After a six-hour flight, NASA astronauts Mark Vande Hei, Joe Acaba and Alexander Misurkin of Roscosmos arrived at the International Space Station at 10:55 p.m. EDT Tuesday, Sept. 12, where they will continue important scientific research. The three crewmates launched aboard the Soyuz MS-06 spacecraft from the Baikonur Cosmodrome in Kazakhstan at 5:17 p.m. (3:17 a.m. Baikonur time Wednesday), orbited Earth four times, and docked at the space station. The hatches between the spacecraft and station will open at 12:40 a.m. Wednesday. The arrival of Vande Hei, Acaba and Misurkin restores the station's crew to six, as they join Expedition 53 Commander Randy Bresnik of NASA and Flight Engineers Sergey Ryazanskiy of Roscosmos and Paolo Nespoli of ESA (European Space Agency.) The new Expedition 53 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. Bresnik, Ryazanskiy and Nespoli are scheduled to remain aboard the station until December, and Vande Hei, Acaba and Misurkin are slated to return in February 2018. This marks the first long-term increase in crew size on the U.S. segment from three to four, allowing NASA to maximize time dedicated to research. Highlights of upcoming investigations include demonstrating the benefits of manufacturing fiber optic filaments in a microgravity environment, a new study looking to slow or reverse muscle atrophy in astronauts during spaceflight, and exploring the ability of a synthetic bone material that adheres bone to metal within minutes to accelerate bone repair. The crew members also are scheduled to receive Orbital ATK's next commercial resupply mission in November, delivering several tons of research, supplies and vehicle hardware. 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 2,100 research investigations from researchers in more than 95 countries.
