Expedition 24 Crew to Double on ISS

Profiles of NASA astronauts Doug Wheelock and Shannon Walker, and cosmonaut Fyodor Yurchikhin. They're scheduled to launch on their Soyuz TMA-19 to the International Space Station at 5:35 p.m. Eastern on June 15 from the Baikonur Cosmodrome in Kazakhstan. Wheelock and Yurchikin are both spaceflight veterans; Walker, the only native Houstonian chosen as an astronaut, will be making her first visit to space. The Soyuz crew will join Expedition 24 crewmates Tracy Caldwell Dyson, Mikhail Kornienko and Commander Alexander Skvortsov aboard the orbiting laboratory.
