  • NASA astronaut Piers Sellers is seen in the Cupola aboard the International Space Station during STS-132's mission to the orbiting laboratory. (nasa.gov)
  • As an astronaut, he flew to the International Space Station in 2002 (STS-112), 2006 (STS-121) and 2010 (STS-132), where he carried out six spacewalks during the assembly of the orbiting laboratory. (nasa.gov)

  • Fortunately, when the space station was designed, planners recognized that having a platform in low Earth orbit (LEO), which is about half the altitude of most Earth remote sensing satellites, provided researchers the opportunity to do something unique. (nasa.gov)
  • That means that instead of passing over at the same time every day, which is typical of an Earth remote sensing satellite, the space station actually has a precessing orbit and does not go over the poles. (nasa.gov)
  • The precessing orbit of the space station laid out over a map of the Earth. (nasa.gov)
  • This review will consider the impact of true and simulated microgravity and other characteristics of the space flight environment on bacterial cell behavior in relation to the potential for serious infections that may appear during missions to astronomical objects beyond low Earth orbit.
