NASA astronauts Joe Acaba (left) and Shannon Walker pose for pictures by a statue of a peacock at the Kremlin in Moscow Sept. 1. The statue had special significance for them since they are members of the Astronaut Class of 2004 that bears the nickname “The Peacocks”. Acaba, Alexander Misurkin of Roscosmos and Mark Vande Hei of NASA will launch Sept. 13 from the Baikonur Cosmodrome in Kazakhstan Sept. 13 on the Soyuz MS-06 spacecraft for a five and a half month mission on the International Space Station.
