The space shuttle Endeavour, which blasted off on Monday for its final mission, docked with the International Space Station on Wednesday.
As the AP noted, the shuttle is carrying, "the most expensive payload ever carried by a shuttle, a $2 billion magnetic device that scientists hope will unravel the mysteries of the cosmos." The Alpha Magnetic Spectrometer will be attached to the ISS on Thursday.
