Shuttle Discovery's Astronauts Sail Through Sixth Day In Space

Discovery's astronauts are sailing through the sixth day of their mission to the International Space Station, stocking the outpost for extended operations after the nation's shuttle fleet is retired later this year.

A new science rack that will enable unprecedented Earth observation research has been put in place in the U.S. Destiny laboratory and a stowage rack that will serve as an orbital closet also has been put in place.

Mission specialists Rick Mastracchio and Clay Anderson, meanwhile, are preparing for the second of three spacewalks scheduled to be carried out on the mission. That excursion is set to begin at 2:16 a.m. Sunday.

Space-to-ground media interviews are coming up just before 6 a.m. and a Naval Post Graduate School educational event is set for around 10:30 a.m.
