CAPE CANAVERAL, Fla. (AP) — After being rushed in from Russia, a toilet pump was loaded into space shuttle Discovery on Thursday just in time for this weekend's liftoff to the international space station, where the lone commode is acting up.

A NASA employee based in Moscow hand-carried the pump on a commercial flight that touched down Wednesday night. Within hours, the pump and related equipment were packed away aboard Discovery.

Discovery is scheduled to blast off Saturday on a 14-day mission. The main delivery item is a 37-foot-long Japanese lab; it will be the biggest room once installed at the space station.
