NASA astronauts Commander Matthew Dominick, Pilot Michael Barratt, and Mission Specialist Jeanette Epps, along with Roscosmos cosmonaut Mission Specialist Alexander Grebenkin, will join Expedition 70 and 71 crew members aboard the station in early 2024 to conduct a wide-ranging set of operational and research activities.

This will be the first spaceflight for Dominick, who became a NASA astronaut in 2017. He is from Wheat Ridge, Colorado, and earned a bachelor's degree in electrical engineering from the University of San Diego, California, and a master's in systems engineering from the Naval Postgraduate School in Monterey, California. He is an active-duty U.S. Navy astronaut. He graduated from the U.S. Naval Test Pilot School in Patuxent River, Maryland, and then served as a test pilot specializing in testing landing on and catapult launches from U.S. Navy aircraft carriers.

This will be Barratt's third trip to the space station. In 2009, Barratt served as a flight engineer for Expeditions 19 and 20 as the station transitioned its standard crew complement from three to six, and performed two spacewalks. He flew aboard the space shuttle Discovery in 2011 on STS-133, which delivered the Permanent Multipurpose Module and fourth Express Logistics Carrier. He has spent a total of 212 days in space. Born in Vancouver, Washington, he Considers Camas, Washington, to be his hometown. Barratt earned a bachelor's in zoology from the University of Washington, Seattle, and a doctor of medicine from Northwestern University in Chicago, Illinois. He completed residencies in internal medicine at Northwestern and aerospace medicine along with a master's degree at Wright State University in Dayton, Ohio. After nine years as a NASA flight surgeon and project physician, Barratt joined the astronaut corps in 2000.

This also will be Epps' first trip to the space station. She is from Syracuse, New York, and earned a bachelor's in physics from LeMoyne College in Syracuse, New York, and a master's in science and a doctorate in aerospace engineering from the University of Maryland, College Park. Prior to joining NASA, she worked at Ford Motor Company and the Central Intelligence Agency. She was selected as an astronaut in July 2009, and has served on the Generic Joint Operation Panel working on space station crew efficiency, as a crew support astronaut for two expeditions, and as lead capsule communicator in the Mission Control Center at NASA's Johnson Space Center in Houston. Epps previously was assigned to NASA's Boeing Starliner-1 mission. NASA reassigned Epps to allow Boeing time to complete development of Starliner while also continuing plans for astronauts to gain spaceflight experience for future mission needs.

Grebenkin, who graduated from Irkutsk High Military Aviation School, Irkutsk, Russia, majoring in engineering, maintenance, and repair of aircraft radio navigation systems, also is flying on his first mission. He graduated from Moscow Technical University of Communications and Informatics with a degree in radio communications, broadcasting, and television.

This is the eighth rotational mission to the space station under NASA's Commercial Crew Program, which works with the American aerospace industry to provide safe, reliable, and cost-effective transportation to and from the orbital outpost on American-made rockets and spacecraft launching from American soil.

NASA's SpaceX Crew-8 Launches to International Space Station

An international crew of four reached orbit following a successful launch to the International Space Station at 10:53 p.m. EST Sunday (March 3) from Launch Complex 39A at NASA's Kennedy Space Center in Florida. NASA's SpaceX Crew-8 mission is the agency's eighth commercial crew rotation mission with the company to the space station.

A SpaceX Falcon 9 rocket propelled the Dragon spacecraft into orbit carrying NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, along with Roscosmos cosmonaut Alexander Grebenkin, for a science expedition aboard the orbital laboratory.

"Congratulations to NASA and SpaceX on another successful launch to the International Space Station! On this eighth crew rotation mission, we are once again showing the strength of our commercial partnerships and American ingenuity that will propel us further in the cosmos," said NASA Administrator Bill Nelson. "Aboard the station, the crew will conduct more than 200 science experiments and technology demonstrations to help fuel this new era of space exploration and benefit humanity here on Earth."

During Dragon's flight, SpaceX will monitor a series of automatic spacecraft maneuvers from its mission control center in Hawthorne, California. NASA teams will monitor space station operations throughout the flight from the Mission Control Center at the agency's Johnson Space Center in Houston.

The Dragon spacecraft, named Endeavour, will dock autonomously to the forward port of the station's Harmony module about 3 a.m. EST Tuesday (March 5).

Crew-8 will join the space station's Expedition 70 crew of NASA astronauts Jasmin Moghbeli and Loral O'Hara, ESA (European Space Agency) astronaut Andreas Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonauts Konstantin Borisov, Oleg Kononenko, and Nikolai Chubb. For a short time, the number of crew aboard the space station will increase to 11 until Crew-7 members Moghbeli, Mogensen, Furukawa, and Borisov return to Earth a few days later.

Crew-8 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include a study of brain organoids to understand neurodegenerative disorders, shifts in body fluids during spaceflight, and the effects of UV radiation and microgravity on plant growth. These are just a few of the more than 200 science experiments and technology demonstrations that will take place during their mission.

With this mission, NASA will maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing science, and developing the skills needed to operate future commercial destinations in low Earth orbit and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA's Artemis missions.
