When it reaches the ISS on Wednesday, the shuttle will deliver nearly 15 tons of supplies and equipment, highlighted by the 7.5-ton Alpha Magnetic Spectrometer, which will be attached to the space station's exterior during a robotic arm operation. Once it's installed, the $2 billion particle detector will almost immediately start sending down data about cosmic rays according to msnbc.
