CAPE CANAVERAL, Fla. (AP) - Space shuttle Discovery's crew is expected to spend its last full day in space stowing equipment and testing the spacecraft's steering jets.
Discovery's seven-member crew also had a break scheduled Friday to talk via satellite with students from President Barack Obama's alma mater, the Punahou ('POON-uh-hoe) School in Hawaii.
2 of Discovery's crew members, Joseph Acaba and Richard Arnold, are former teachers.
Obama talked to Discovery's crew while they were still docked at the international space station on Tuesday.
Discovery is due back on Earth on Saturday after its mission to deliver and install power-generating solar wings at the space station.
