Four women on the International Space Station pose for a photo in the Zvezda Service Module while space shuttle Discovery remains docked with the station. Pictured clockwise from the lower left are NASA astronauts Tracy Caldwell Dyson, Expedition 23 flight engineer; NASA astronaut Dorothy Metcalf-Lindenburger, Japan Aerospace Exploration Agency (JAXA) astronaut Naoko Yamazaki and NASA astronaut Stephanie Wilson, all STS-131 mission specialists.
The STS-131 mission’s seven-member crew launched aboard space shuttle Discovery on April 5 from NASA’s Kennedy Space Center, joining the six residents of the space station when the shuttle docked on April 7. The merging of the two crews marked the first time four women were in space at the same time.
