Posing for a portrait aboard the International Space Station (from left) are, NASA astronauts Jeanette Epps, Tracy C. Dyson, and Loral O'Hara, and Belarus spaceflight participant Marina Vasilevskaya. Dyson and Vasilevskaya, along with Roscosmos cosmonaut Oleg Novitskiy (out of frame), were the newest visitors to the orbital outpost after docking to the Prichal docking module aboard the Soyuz MS-25 crew ship. #nasa #astronaut #belarus #spaceflight #participant #cosmonaut #international #space #station
