EDISON - After two days in flight, the space shuttle Endeavour docked at the International Space Station this morning, NASA officials say.

During their stay, the astronauts will install a $2 billion Alpha Magnetic Spectrometer, which will hunt for dark matter, cosmic rays and other galaxies.

Endeavour also hauled up supplies to help outfit the station. The shuttle will remained docked there until May 31.

The mission is commanded by West Orange native Mark Kelly. The shuttle blasted off on Wednesday morning from the Kennedy Space Center and the launch was attended by Kelly's husband, Congresswoman Gabrielle Giffords, who is recovering from an assassination attempt.
