NASA astronaut Shane Kimbrough and Russian crewmates Sergey Ryzhikov and Andrey Borisenko landed back on Earth today after spending almost six months on the International Space Station. The three left the station overnight in a Russian Soyuz craft and made what NASA spokesman Rob Navias called a “bull’s-eye touchdown” on the steppes of Kazakhstan at 5:20 p.m. local time (4:20 a.m. PT).
