Expedition 37 NASA Flight Engineer Michael Hopkins waves to friends and family at a news conference held at the Cosmonaut Hotel in Baikonur, in this NASA handout image taken September 24, 2013. The shutdown idled most of NASA's 18,000 workers. Only 550 employees were considered exempt, including American astronauts Hopkins and Karen Nyberg serving aboard the International Space Station and flight directors at Mission Control in Houston. Skeleton staff maintain key science and communications satellites but work on new missions, including preparations to launch a Mars probe on November 18, have been suspended, said NASA.
